[Q] Why does JB 4.1.2 not connect to wifi properly?? - Galaxy Note II Q&A, Help & Troubleshooting

Hello all. I have been playing with the new 4.1.2 JB ROMs on my 7100 Note2 and have been having one major and repeatable issue, that I have seen mentioned a few times by others, with no obvious resolution.
I have tried the various leaks of the 4.1.2 that were floating around (the stock one, Wannam and Android Revolution HD 5) and now I have just tried the final Polish PLAY version of 4.1.2 as well as the latest Wannam as well. All do/did the same thing:
They can see my wifi SSID and they can BEGIN to connect and "obtaining IP address" comes up. EITHER they then fail and tell me connection is poor and to try again, or they will connect and then drop within a minute. Just today I made some kind of movement on this by trying different kernels. Perseus25 gives up and tells me signal is poor. Perseus27 WILL actually connect and stay connected but can never actually surf anywhere. Note2Core will either connect or tell me my authentication is wrong (which it isn't) and when connected, it too refuses to surf. RedPill is same as Note2Core. BTW, even when they DO connect, they do so at a measly 5Mbps (and cant find internet)
Now, you are all probably thinking "his wifi is rubbish!" but I REALLY cant see how that can be! Firstly, there are other users out there who have mentioned this in a few threads but I have never seen any useful replies as to a solution (or a cause!). But also, if I restore back to my usual ROM which is Android Revolution 4.1 HD (=JB 4.1.1) with a perseus25 kernel, then I connect immediately and stable at 54Mbps and works great. (all it takes is a CWM restore back and it is working 100%. same location in my office, same router, wifi etc!) Plus same wifi serves two laptops, wife's Galaxy S2, and has seen many iphones, ipads, and other laptops all fine.
Back in the days of the leaked 4.1.2 I DID try jumping wifi channels on the router just to prove a point. Every single one did same thing.
Flashing procedures have been the 'standard' method: boot into CWM, wipe data/cache/dalvik/battery, then flash new ROM, boot OK.
I had assumed that the early leaked version of the ROM had some bug but very disappointed to find same behavior in the Polish PLAY version which is final release AFAIK. It makes all these subsequent ROMs based on it totally useless to me.
I even extracted and flashed the modem.bin from my working ARHD4.1 ROM but nothing changed. So modem and kernel same as working systems but something clearly broken somewhere.
If you are one of the other folks out there who also has this issue, might be helpful if you give some info about your setup, so somebody clever out there can help us join the 4.1.2 club?!
Any thoughts?
(setup: UK VirginMedia 120Mbps down/10Mbps up. Cisco Linksys E4200 router. about 10 feet from router with one 'paper wall' between! ARHD4.1 finds full signal and surfs fast. 4.1.2 totally unusable)
Help me Obi-Wan Kenobi(s), you are my only hope!

I have noticed similar problems on my SGH-i317 using CleanROM 3 (4.1.2). The wireless connection randomly drops while browsing. This happens even in areas with excellent signal quality.

Thanks for contributing. Helps prove the point that it is something in the new ROM as our wifis are fully functional otherwise. I have matched the modem and kernel from my working 4.1.1 system and still failing....
I hope we get some help.

I also got this problem from latest WanamLite & Omega ROM. Both are using 4.1.2 JB.
Wifi detected and connected but always obtaining ip address..
Sometimes it tooks so long and can get ip, but still cannot access internet or can't even ping different ip address from the same network.

strange, i've been running omega 7 to 7.4 but dont have any problems with wifi.
i've connected to home wifi (TP-Link), workplace (Cisco/Linksys) and some coffe-shops without any problem.
most of them using WPA2 or WEP. sometimes obtaining ip address with WEP could take a lil longer about (10-15sec) but always a success.
but never used wanamlite for my note2 so cant comment any, srry

I'm not saying the issue is in the wifi itself, but it can probably be fixed by disabling n mode and only using b and g. Also try to make sure the phone gets assigned a static ip.
Issue seems to be 4.1.2 related.

yes.. i'm also facing the same problem.. whenever i flashed custom rom based on 4.12, like wanam 2.0, 2.1 n crash rom, i cant connect to the wifi.. it always shows optaining ip address and it never connected.. now i m using stock rom 4.11 n there is no problem to connect to the wifi..
i juz wonder why it happens to several devices only?

I having the same wifi problem with 4.1.2 firmware...revert back to 4.1.1 wifi connection run flawlessly..strange !

I have tried switching OFF the 5GHz signal from my modem and sticking to 2.4GHz.
Have also tried turned off N and locked it down to just B & G.
Have tried turning off the WMM in the QoS section.
All of these have been mentioned around the place as possible solutions, and I am afraid none of them changed anything at all for me. Also read that one person had his wifi issues resolved when he dropped WPA2 security and went back down to WEP. This is an unacceptable solution to me as I don't want to make my WiFi so insecure, and also, what happens when I go to my friends and family who all (rightly) use WPA2?! So wont even be trying that.
I am actually getting a new Virgin Media Superhub in about 2 weeks so will revisit the issue then to see if 4.1.2 just doesn't like my Cisco router.
Just weird. And frustrating as wanted to move on to 4.1.2!

have you tried changing the channel on your n router?

Ok. I here is my evo 4G lte story. I flashed cm10 as soon as I got this phone a month and bit ago. I totally had wifi connectivity problems at work and at my house. One worked better and one had to be spammed to connect 20 times to connect and would still occasionally drop. I went to sense is from there and found it to be reliable. Though I just moved to the ota, I find this sense to be just as reliable.
In all. The new ota let me move to jb with reliability.

Why not all people getting this wifi problem using 4.1.2 ROM? Does the device something problem? But why going back to 4.1.1, wifi problem dissapeared and can connect directly?
Really2 weird....

yes.. i also wonder why this happen..

I also have exactly the same problem. I have tried every single 4.1.2 ROM but I can't keep my wifi working. I have had to go back to 4.1.1 as well. My wifi is perfect on 4.1.1. I use Cisco e4200 with ddwrt flashed. Very frustrating!

Try changing channels to below 11 if you're in Europe and the router uses channels above.

I`am on ARHD 6.0 currently and i never had problems with wifi on all the previous ARHD rom`s. Try doing a full wipe or at least also do a system wipe (and wipe cache/dalvik cache, data/factory reset and format preload) before flashing a rom. I`am sure that will help guys.

i have same problem no ip adressing and when i set statique ip no internet
i test Omega wanam mondx... same issue
omega 6.1 works great but at 7 version no internet by wifi, but ok in data
i have a logcat if help (catlog app)
i test rest router, change wpa2 to wpa, change channel, wps, super wipe (allll format) every omega rom, set mac adress in router with static ip
i become crazy why not on all device its n7100 XEF french buy on amazon

[Q] Wifi Problem

Guys, my wifi is acting really really weird lately.
I flashed aokp m4 with franco r98, and it works perfectly with my home wifi. But at school, it would not connect even though in wifi settings the phone can see the wifi and its full bars. I stood next to a friend with a gnex unrooted and stock Rogers rom, and he has full bars. While on my phone, it just says that the network is saved. I have been able to access the wifi before back when I had stock. So I decided to try my cwm backup of my stock rooted and still no use. wont connect.
Last try i made was to reflash google 4.0.2 stock image and lock bootloader, and try it with the factory rom. NOPE, no help at all..
Right now, Im back home on my wifi, full bars, and no problems watsoever running m2 with r98 again. but still...why???!!!
Is it hardware issue? How can I test and check!!! i really need this solved...as wifi is like a necessity in life these days LOL
Also, I tried foxhound before i went to stock, and still wont connect to school wifi.
One more thing, there is like one spot to two in school that i would get 1 tiny dot of wifi, whereas every other phone around me including the ipods have full bars...SOooo, any fixes?
anyone help ?

Before you flashed your custom rom did it work at school?
If it works at home, then it probably isn't a hardware issue... maybe check your wifi settings and try putting the frequency at 2.5 Ghz instead of auto? Or try to put it at 5.0 Ghz?
Maybe there are some Wi-Fi apps you can try searching for in the market that gives you more information?
You sure you're typing the correct password?

a week before I was on aokp m4 with r98 and things were fine. this week, the problems began. tried changing the accepted frequency, tried srock rom, tried stocj rooted, tried using someone else's sign in info. what wifi app should i get...thanks for the reply
Sent from my Galaxy Nexus using xda premium
I'm not exactly sure about the wifi diagnostics app, I just got my phone a couple days ago
I'd say just download some random one's for now. See if the signal that it's reporting is different. Maybe long press the network name and select "forget", then try again?
Are you not getting enough bars? Or can you just can't connect to the AP?

problem with wifi

I have problem with my nexus, wifi is connected but I cannot access any internet. Sometimes interet works normal, then suddenly disappears, wifi is connected normal but there isnt internet
I tired wih other android phone, samsung galaxy ace, but same thing
But nokia n8 works normal, this dosnt happening
I do not know of which can be either the router or the phone
I tried to change settings on the phone and the router but nothing
If someone has an idea, I would be grateful to him
I had the same problem on my nexus, while the wifi worked fine on other devices. I flashed several different ROMS, to no avail, and resolved myself to believe that it was a hardware problem. Before flashing back to stock, I reset the Router, just for laughs. Problem solved. Make sure your wifi settings on android are correct, and try resetting your router. It's worth a shot. Which ROM are you on?
i tired several times with reseting router, even change settings, sometimes internet start to work but after 30-40 minuts stops again
i dosnt now what exactly ROM is on phone, becouse i just buy him
Without knowing the ROM, and at the risk of sounding like a tech support douche, maybe you should try a wipe/factory reset.

Hi,
I am new to dealing with the Android OS with my Galaxy Nexus, but I am thinking the same thing. My main concern is backing up and reinstalling all of my information, apps etc. I use Titanium backup pro for my backups but would like to know if my phone will be recognized when I try to reload all of my apps.
Thank you for your reply.

I have WiFi problems at my house. It shows that I am connected but no internet. I know is the router in my case.
I would test your WiFi somewhere else, such as Starbucks or Barnes and Noble.

Hi,
I have connection everywhere - Starbucks, home, Staples, Chapters/Indigo (Barnes and Nobles equivalent in Canada), even borrowing Wifi from unsecured home networks etc. but the disconnect is between the Wifi and getting my Internet to connect. Connection bars are all gray and at home very strong signal showing. This reminds me of connection problems I had with my laptops (running the MS OS of course), but in the Android OS I am a "newbie" and reading forums trying to figure what other people's connection problems are, and how they were solved.
There are no Wifi connection problems using my laptop (now) or my daughter's iPods, my wife's Blackberry Bold at home. My data works find, and I wish there was a roll back feature to the time just prior to the problem occurring last Thursday. My understanding is I have to completely restore my system, and this leads me to more questions about if I can reload all of my apps or if I will have to pay for them again. In the end, it may be faster.
I downloaded - per member recommendation - a Wifi analyzer and it shows that my home Wifi speed is excellent.
Thanks, I am always open to ideas to solve.
Do you know how to find the version of ROM on my Galaxy Nexus? I must look.

[Q] Wi-Fi "Authentication error occurred"

So I have tried to trace my issue to it's roots and after a lot of investigation I decided to make this thread.
The issue:
When connecting to home wifi network I get "Authentication error occurred" even though it's the good password.
It first occurred on stock 4.1.1 ROM with stock Kernel even before rooting. What's more interesting is that I've successfully used the same wifi network for around a month. Other devices connect just fine, no settings on the router changed when this started happening. Didn't fiddle with any settings on the phone neither. I can connect to free wifi APs just fine.
What I've tried:
Dialing *#0011# and from service mode disabling wifi power saving feature.
Using all possible encryption combinations on the router (Open - no password, WEP, WPA-PSK AES and/or TKIP, WPA2-PSK AES and/or TKIP or both WPA and WPA2 at the same time), switching channels, disabling 802.11n mode.
Using some modded wpa_supplicant files from this thread.
Using a bad password just to get a different error.
Downloading some other wifi connectors from the Play Store including Wifi Connection Manager which claims to "Fix device Wi-Fi problems." by cleaning the stored wifi config files and maybe something more.
Flashed Omega v10 ROM with Perseus kernel.
All these things and basically any combinations of them worked to no avail. And the only thing that helped was being very close to the router. That way I manage to connect but moving a couple of meters away, like to a nearby room, and it starts giving the same error even though the network strength is still full at that point.
My thoughts:
I saw a similar issue at a couple of places including a similar thread last active dec 23rd, Android issues on code.google.com and androidforums, but no solutions found there worked. Also comparing how my old original Note and an even older LG P500 perform, the wifi signal is obviously weaker on the Note 2. My area is not heavy on wifi networks, so my guess is there's something wrong with wifi drivers or configuration. Sooooo.... What can I do to remedy this issue and also is there any way to beef up my wifi in the process?

I had somewhat the same issue. Autentication error.Even though WIfi worked properly on my Galaxy y.
From v9, I flashed v6 Omega and then everything was working fine. So go ahead and flash Omega v6.
And after that did you go back to a Jelly Bean ROM?
Edit: at first I figured omega v6 wasn't JB, but then I checked... For the peace on my mind I'll try flashing Omega v6 later today.

When I went to v6, all was working well. But when v10 was released,i flashed it,hopiing that the wifi issue is not there but alas same result.
Before flashing,I made a backup of my wifi folder found in root folder /etc/wifi .
After flashing v10, and overwriting the wifi folder with the one that i had backed up, the issue was solved even on 4.1.2 for me.
Worth a try mate.
Do report back.

Authentication Problem Wifi - solved for me
Hi folks - I had the same issue with my Galaxy Note I717 (it's the AT&T Note 1) that I got yesterday. I have no problem with my T959 Vibrant to connect to my router at all. But the Note always gave me the authentication problem. So I took it with me to work today and no problems at all to connect to Wifi over there - everything just worked fine.
Back at home - same issue. So I was thinking about to reset my router when I saw this button on it's side and I remembered that I had read something in the settings of my phone.
So that's what I did: When choosing the network on the phone I went to advanced settings. WPS - here I choose Push Button. After that I pushed the button on my router and voila everything worked as supposed.
After switching Wifi off and back on there was no authentication problem anymore. So to confirm the whole thing I let the phone forget the connection and I had the same authentication problem. After choosing WPS "push button" and pushing the button on the router everything worked again.
I don't know - maybe it's just basics for a lot of guys here, but I was glad to figure that out by myself and maybe it helps someone else.
In the case that it might be important - my Note runs stock ICS 4.0.4, stock kernel. is rooted and unlocked. The Vibrant runs ICS Passion V13.1 and Kernel Kiss Yum Yum Good #2. The router is a D-Link DIR 655 Wireless N
Following up the thread:
No, flashing omega v6 didn't work for me.
What I found out is actually 5 GHz band routers work just fine (for example at my university) and all the 2.4 GHz ones give the same error if I'm not close enough to them (something like 5 meters with straight visibility and 2 meters behind closed doors with my home router Comtrend WAP 5813n).
I have called Samsung's Warranty Center to ask for assistance and since we don't have official Samsung service centers in Lithuania, they told me partnered service centers might just return the phone to me as it is and so they would call me when they found out more about this issue (that was almost 2 weeks ago). Will call them again tomorrow and will post any updates if the story develops.
EDIT: After talking to them they apologized for taking so long and assured me I was not forgotten and the issue was forwarded to UK because they have no records/info about it here in Lithuania. Strange thing is I still have my phone, they didn't even wanna check it out.
Note 2 wireless issues
Lads I tried EVERYTHING to get connection working after it dropped on me after a month. Done everything I have read on every forum. EVERYTHING. All other Samsung devices work fine except this note 2! One other odd thing I discovered. It connects fine to any modem or roster fine then when try again on each it won't. You tell me guys? I had it with this issue. Help before I chuck it in Port Phillip Bay!
Hello Jumbo,
i had the same problem and read a lot threads about this error message.
For me it looks like not all who get this error have the same problem.
Some wrote that they fixed it by
- exchanging the wifi folder with the one from 4.1.1..
- flashed a different kernel
- downgraded to 4.1.2
- changed wifi energy saving stuff
- messed around with their routers
and so on..
I also did all this stuff but with no success..
In my case I figured out that
- the same problem exist on 3 different routers (so it couldn't be a router issue)
- the wifi speed (when I sometimes got connected) kept falling from 65MBit down to 5MBit
and by having a wifi connection, I couldn't reach any webpage.
- then I recognised, that I only had a working connection, when I was close
to my router, like 1 or 2 meters without anything between us. In this case
I had no problems with authentication and to surf on the web.
I decided to send my Note2 in for a repair, and guess what... They changed my
Mainboard and since then, everything is back to work..
How long did it take for the repair? I can't imagine being without my phone for an extended period....
I know, it's an addiction, but I'm ok with that..
Steve
I have an identical issue with my S3 GT-I9300
For a totally reliable wifi connection, I've had to site the cradle for the phone on top of my router!
Am out of warranty, so if anyone finds a fix for this that does not involve a mainboard change...
(My first post on this site- I just wish it had been a fix rather than a query)

Sorry for the late answer.
My repair took 1 week...
shipped it to w-support on Monday and got it back Saturday.
I was really happy with w-support here in Germany.
I've reset my device to stock and so far it's been sitting @ warranty center for a week, no answer about the roots of the problem yet..
May have found a solution
Hi,
I had the similar problem. With me it started happening after I changed to a Zyxel modem. After some investigation I noticed that in the Zyxel the default gateway is set at 192.168.1.254 whereas most other brands use 192.168.1.1.
Have an inkling that Android doesn't play nice with non-192.168.1.1 gateways.
So changed this in the router settings.
To be sure I also allocated fixed IP on the LAN to my devices and made sure that in the advanced settings of my WiFi network on the Android device I made sure the primary and secondary DNS addresses matched those that the router uses.
Oh.. And to top it all off I fixed the broadcast channel of the router to channel 11 (Probably best you use an app like WiFi Analyser from the Play Store to find the channel that works best for you)
This seems to have solved it for me for now. (I know, not a very scientific method, but got fed up with trying to isolate the culprit)
BTW. Am running (1) Galaxy Note on latest stock ROM (rooted though) (2) Galaxy Tab 2 7" (stock JB ROM - non rooted).
Hope this helps..
Sounds so strange that gateways and channels did it for you. I've tried to change channels on my router with no results. Also I have tried way too many routers before I decided router settings were not a problem. I guess we may have different kind of hardware/software faults resulting in same error message.

I know. It is weird.
Mind you only a few hours have passed since my changes. I'll keep an eye on it if it reverts to it's old state.
Ok.
Had the same issue again this morning, but oddly enough, once it connects, it stays connected. Also when the phone is put to sleep.

[Q] losing wifi connectivity- full bars but all gray

so, I've read around here on the XDA forum about problems with wifi connectivity where we have full bars for wifi but they are gray and you are not getting out. many describe my situation but I've not seen any real solutions...
my problem is that I can connect to my wifi router without issue but then a random amount of time later, sometimes fairly quickly and sometimes it's hours later, I will pick up the phone and see full bars but they are gray and I'm not getting out. I can try opening a terminal window and pinging the gateway/dns servers and can't even reach the gateway.
things I have tried:
- turned off MAC filtering on the wifi AP
- switched from a 5 GHZ wifi on the AP to 2.4 GHZ net on the AP and vice versa
- manually set the phone wifi preference to one or the other (5 or 2.4)
- battery pull on the phone
- delete network settings for my AP and reconfigure
I have not yet tried a static IP config on the phone but I can easily try that... {edited to add} well, I tried static config and that didn't help at all...
one other tidbit of info, I have a work Blackberry with wifi and it never loses wifi connectivity so this is a problem unique to my Nexus.
I'm running Cyanogen 10.0.0-toro and no, I haven't tried a full wipe and reload yet.
thoughts or suggestions?
I'm not trying to threadjack here, but I just wanted to share my experiences.
I've been have the exact same thing happen to my phone (Nexus maguro). I've tried every JB rom I could find, several different kernels and my wifi eventually always goes grey on me. All network activities stop. I'm back on stock everything right now and it still happens.
It happens on my home wifi as well as work wifi.
I'm about to puttstock ICS on my phone and try that out for a couple days.
Anyway, good luck with your problems, i'm going to follow this thread in hopes you'll get a solution that may help me.
If I do figure anything out i'll post back.

I've been have the exact same thing happen to my phone (Nexus maguro). I've tried every JB rom I could find, several different kernels and my wifi eventually always goes grey on me. All network activities stop. I'm back on stock everything right now and it still happens.
It happens on my home wifi as well as work wifi.
I'm about to puttstock ICS on my phone and try that out for a couple days.
Anyway, good luck with your problems, i'm going to follow this thread in hopes you'll get a solution that may help me.
If I do figure anything out i'll post back.

seems that this is a topic that has been posted on a bit over time with no real single culprit or fix. I'll post back if I figure anything out... I know in the Cyanogen thread, I saw info that stated that the MAC address of the phone was changing and I'm going to try and determine if that is happening to mine.
I have the same issue. Sometimes even when i pick up the phone, if i look fast enough i see that the Wi-Fi bars weren't even there! Thats only 1 out of 5 times though. The other time its usually just grey bars. Sometimes it actually will click back and they'll flash to blue and grey 2-3 times and then go solid blue. Then sometimes like you, they'll stay grey. I've tried everything too...reverting to stock, Different kernels, ROMs, routers, static IP, 2.4 or 5ghz, full auto mode. The only fix that makes it a little more reliable, is using Wi-Fi PM Fast. But even that, is not reliable. I'd say its about 50% reliable then, for a huge sacrfice in battery life. For me i've noticed this started to happen with 4.2. Before that i never had a problem. All other devices though no problem. My Nexus 7 is just fine. But the galaxy nexus, no matter what router or where i am, the Wi-Fi is totally unreliable. For me, it happens within 2 minutes that it will disconnect most times. Then 1 in 10 times it'll be fine for 10 hours.
In all honesty, i've given up. Just come to deal with it. Use mobile networks when i'm not needing to download. I can download files and stream music just fine too. If there is traffic going through, it never disconnects. But when its just sitting there without traffic, it disconnects, or, loses connection to google servers i should say.
well that's not good to hear...
I installed stock 4.0.4 a couple days ago and have not had my wifi go grey on me yet.

yeah, I love Cyanogen so not willing to go back to stock... waiting for them to finish 10.1 and I guess I'll see how it behaves then.
Hi all,
Just to say that I have the same problem. I have been upgraded from ICS to 4.2 and nothing had happened but I had to downgrade to 4.1.1 (AOKP Build 4) due to other issues and after that I started notice the WiFi problem.
At first I thought it was when the screen went off, but I has happened with screen on too. I have to turn WiFi off and the back on to connect properly again, very annoying.
As I said I started noticing this after I downgraded, but then again, I had used AOKP 4.1.1 before without this issue. I think that it is time to change my phone :/

so, I've read around here on the XDA forum about problems with wifi connectivity where we have full bars for wifi but they are gray and you are not getting out. many describe my situation but I've not seen any real solutions...
my problem is that I can connect to my wifi router without issue but then a random amount of time later, sometimes fairly quickly and sometimes it's hours later, I will pick up the phone and see full bars but they are gray and I'm not getting out. I can try opening a terminal window and pinging the gateway/dns servers and can't even reach the gateway.
things I have tried:
- turned off MAC filtering on the wifi AP
- switched from a 5 GHZ wifi on the AP to 2.4 GHZ net on the AP and vice versa
- manually set the phone wifi preference to one or the other (5 or 2.4)
- battery pull on the phone
- delete network settings for my AP and reconfigure
I have not yet tried a static IP config on the phone but I can easily try that... {edited to add} well, I tried static config and that didn't help at all...
one other tidbit of info, I have a work Blackberry with wifi and it never loses wifi connectivity so this is a problem unique to my Nexus.
I'm running Cyanogen 10.0.0-toro and no, I haven't tried a full wipe and reload yet.
thoughts or suggestions?

I'm on Muzzy 4.2.2 and I'm currently having the same problem. It's not a new problem since I remember having it months ago (disabled my phone's WiFi because I kept missing emails and other notifications - grew tired of dealing with it). I thought it was my router, so I swapped it with a newer one recently, but it carried forward (old router was TRENDnet Draft N and the new one is ASUS RT-N66U).
I would like to know how to properly troubleshoot this problem.
I'm glad I didnt have to create a thread for this. I have been facing this problem quite a lot. I can confirm that WiFi works absolutely fine until 4.1.2, whether it is stock or CM10 (I havent tried the other ROMs yet). I have faced this problem only from 4.2. It still exists on 4.2.2. Happens on all the ROMs I have tried till now including CM10.1 nightly as well as the stock factory image.
When the phone is sleeping, it seems to lose WiFi connectivity and when woken up, the WiFi bars is grey though it is full. If I am very lucky, it will turn blue automatically. Most of the times, I have to switch WiFi off and back on for it to connect properly.
Anyone knows the root cause for this? In case this has been discussed in any other thread?

have you posted this information over in any of the threads where the developers are working such as Cyanogen in an effort to bring this issue to the forefront for more visibility?
I have had those wifi problems with every android version and rom I had on my GNex as far as I can remember.
Sometimes it will be able to reconnect but sometimes I have to disable and re-enable wifi to get it back.
I too thought that it might have been my crappy router as I have had multiple problems with it over the years (some Linksys router).
This is really annoying because it won't receive any e-mails until I randomly decide to have a look at my phone. :/

trust me, I understand your frustration... some days, I can go almost all day without loosing wifi data throughput and other days it won't last 10 minutes without going to gray bars.
unfortunately, no one is sharing any fixes which tells me that no one has a good handle on the problem.
Same issue for me on stock Android 4.2.2. Leave WiFi on overnight and when I wake up its connected to WiFi but gray bars...

The update to 4.2.2 drivers have fixed all WiFi issues for me. For the first time since 4.1 I can now use WiFi optimization now. And WiFi is fully reliable.

same thing happened to me on toroplus sourcery 5.1, after trying everything i could think of and talking to one of the devs, i finally did a fresh download of rom and gapps. wiped cache,wiped dalvik, factory reset, wipe system, deleted android folder off of storage then installed the fresh download of rom and gapps and its been working great for me since. hope this helps.

Can you elaborate on this? I've flashed 5 different modems and still get this problem... it happens to my cell service bars, as well. Would love to know what the cause is.

i just know ever since moving to a 4.2.2 kernel that has the 4.2.2 drivers my wifi has been stable. I know there was a post in the anarkia thread with the ak kernel that had the drivers. but i believe most any 4.2.2 kernel would have them implemented. i do have the newest bootloader and radio too. but i know as soon add i got the 4.2.2 drivers all issues were resolved wifi wise. of course i think if you have a 4.2.2 kennel you'll have them.

I'm looking forward to that update - I've been watching the Cyanogen threads for when I think the 10.1 has matured enough to become my daily driver... good to know you've had positive results!

me facing same issues , Solution would be to use an app called wifi fixer by zanish-g1 from the play store ...
it worked for me !! :good:

One X Wifi Problems After 4.2.2 Update

Hello, i know this has been discussed here before, but i wanted to ask for help anyway. My Wifi was working perfectly fine on Android 4.1, but after this update to 4.2.2 its really bad.
I know its software issue, pressing right top corner of my HOX doesnt help at all. I tried factory reset, but it didnt help. I´m running official ROM and no root. The problem is that sometimes when i have full signal strenght, the wifi speed is still horrible (like 0.5mb on 10mb wifi).
Any suggestions what to try? Thanks a lot

I have exactly the same problem. All HTC customer service suggested was factory reset, tried that and no difference. On 4.1 it worked fine on my wifi at home throughout the house, now on 4.2, works ok downstairs but useless upstairs even when it says I have 4 bars of signal. Very one times flaky though and sometimes drops to 1 or none. This is a disaster as I understand there is no way to roll back to 4.1. This is unbelievable!! How can an official update totally break basic functionality with no way back!? Searched all over Internet to find a solution and no luck, even though a fair few people seem ro have this problem. Is not a hardware problem, as OP, squeezing top right makes no difference. Have tried static IP, doesn't help. Desperate for help, can any wise heads on here suggest anything? Thanks!
So wish I had not updated, it worked brilliantly before.
Same situation here after the update... With full signal keep having horrible Wifi speed... :'(

Do you have the same problem 4play975? Seems quite a few people do..! As per OP my phone is not rooted and don't want to root it really.
Any chance anyone can suggest any other solutions to try?
Failing that, some details on what Richmondos fix is would be useful!!
Yeah, I really dont want to root my phone too, because i have warranty for more than 1 year now and I will sell the phone in future, so I dont wanna risk loosing warranty..
I also have similar problem! But it varies, sometimes it's bad and sometimes not??? Phone is stock and locked and don't want to unlock and install custom stuf, until warranty period is over.
Hello to all
I have the same wi-fi problem on my HTC One X since I made the update.
Is there any way to solve this?I hope so, because Wi-Fi signal is very bad, and I use it a lot of time.
I have CWM recovery installed,bootloader unlocked, and s-on, recently I have rooted my phone,
but at this moment is not.
I dont care installing new kernel, radio,etc........I just want to solve this problem :crying:
Tanks to all
I have a problem with my wifi too since the Andriod 4.2.2 and Sense 5 update, but it seems to be a bit different from yours. The speedtest.net app and the ping & DNS app give the same results as my PC that is hard wired to the router, so speed and ping seem to be fine.
But I get errors like Connection Problem Authentication via the proxy server was unsuccessful - but I don't use a proxy server. In the HOX wifi settings for that router the Proxy settings are Manual, Proxy hostname 127.0.0.1 and proxy port 3128. Are these correct for when there is no proxy? If switch from Manual to None and go back in then it has gone back to those settings.
Another error is Connection Problem this page contains too many server redirects. But the page displays fine if I switch to mobile data.
Or I get Connection Problem there was a network error. Again it works fine on mobile data.
Then there are some webpages that give a 404 page cannot be found error. Again it works fine on mobile data.
Some of these problems are repeatable on the same webpages across different routers in different buildings.
Sometimes when connecting to a router the HOX connects and the loses the connection and then reconnects up to 10 times before settling on the connection.
Like you I would rather not root etc if possible.
So, noone know a solution for users without root? I found out that on some wifi (in school), it works quite fine even on worse signal. But before update, it was ok on every wifi..
Hi
i have the same problem with my wlan connection. Nearly 100kb/s.
I had tested my internet download speed on my computer and takes interesting information:
my internet connection is 70MBit, this means i can download with nearly 8,2 MB/s.
If my HOX is not connected to the router, the whole downloadspeed is available on the computer. But if the HOX is connected, the downloadspeed is only 1 MB/s.
After disconnecting and rebooting the router, the internet connection is as well as before.
Does anyone makes the experiences?
regards
Daniel
I don't have the speed problems, Speedtest.net app gives the same results on my HOX as my PC.
One of my wifi problems is to do with the Wi-fi connecting to a weak signal instead of the stronger one - I have worked around this by installing WiFi Fixer App which works well at switching to the stronger signal.
Also there are some websites that give errors like Server Error too Many Redirects (for example http://www.thefreedictionary.com/ does that for me) or 404 Error - Page Cannot be Found (http://fahrbot.co.uk/) or are sometimes slow to load - I have found that these issues don't happen with the Opera Mini app, so why does the stock browser give these problems when on wifi, but not on mobile data?
Another one is that if I click a link in a webpage (or type in a URL) that takes me to a webpage that has a mobile version as well as the desktop version I get a strange URL that doesn't work. For example on mobile data typing in www.abmobileapps.com takes me to the mobile version of the website, but on wifi the URL automatically changes to http://www.abmobileapps.comhttp/www.abmobileapps.com/ and the page cannot be found. Again it works in mini Opera on wifi.
WIFI FIX
if you use rooted device, use lyapota mods and flash modpack http://forum.xda-developers.com/showthread.php?t=2114584 (contin wififix and other).
for me works great :highfive: (my router has openwrt)
I found out that on some other wifis speed works just fine. I have router D-Link DIR-600 with stronger antenna than it was stock. I use WPA2 security and Dynamic IP.
Is there anything what I should try to fix it? Thanks for any suggestions.
Here are some advices how to fix the WiFi issues - router dependent (need access to the router setup):
1. Make sure that you are not using channel 11-13
2. Disable "WMM Support" in router Wireless -> Advanced Settings. Note: this will force G-only speed (54Mb)
3. You you want to keep the N speed, put your phone in the highest possible QoS priority without disabling the "WMM Support"
Hope this helps

Thanks for the tips...
So, we will change WMM settings for all wifi modems that we connect...
Shame on you HTC...Next time I will ignore HTC while buying a new mobile phone...
after flashing lyopotas mod pack my hox'S wifi seems to work again like it's supposed
maybe it helps
After update,
i can't use my home wifi (Innacomm),using other wifi okay.
conneted but can't surf internet (error 404) but can only use opera mini (very very very slow).
Using other device no problem with the wifi..anyone can help me? TQ :crying:
The problems I am having with proxy and 404 errors are all caused by the Web Protection feature in Kaspersky Internet Security for Android since the OTA to Android 4.2.2 (it worked fine previously). I have installed the latest KIS 11.1.4.141 from the Kaspersky website (because Google Play says it is up to date at version 11.1.3) but the problem still occurs. So I have turned off Web Protection in KIS and all my issues have been cleared up.
