[Q]Could the wifi router be the culprit?

I have previously posted on how my WiFi was only working via a ****ty app.
Now I have some more info that makes me beleive that our home wifi router is the cause of that.
I went to my friends house and WiFi worked completely normal there, so it must be the routers fault right?
I have also reflashed the radio, so it probably isn't it's fault.
It all started happening when I updated to the OTA 2.2
Any help on how to fix this?

what about flashing a custom rom?

Well, I'm running CM7 with 2.3 and it's still the same :/

I don't have pc wifi to experiment with. But I will try to tell something.
Wifi on wildfire has the support of b and g networks by default. So no wifi "n" network on wildfire by default. There is a chance of difference in these network types between ur wifi and ur friends wifi, such that it works only with ur friends one.
And I think I saw somewhere in development section that someone made wifi "n" network working on wildfire. But Im not curious about it since I don't use it.

But what's really odd, is that it worked like it should on stock 2.1, so obviously 2.2 ****ed something up...right?

[Q] CyanogenMod 10: Wifi Problem?

Hey There,
I've just installed this fine ROM today, and it seems great,
but for some reason, the wifi reception is BAD now.
It works fine if I seat near my router, but if I move 3 meters away
it looses the connection ... and says the reception is POOR.
Any1 else has this problem?

Which version of CM10 did you flash, if it's anything older than beta 1 try flashing Beta 1 ? if you still have problems after Beta1
Try flashing a different kernel and see if that resolves your problem. (if i can spare you some time, try faux123's kernel)
http://forum.xda-developers.com/showthread.php?t=1647993
And then if you still have problems.
Try running the Viper ROM 2.6.0 with the Butter hacks runs very smooth.

Thanks for the quick replay
I flashed the "[08-09] [ROM] CyanogenMod 10 - Endeavor Unleashed" rom.
I don't think this is the same cm10 everyone's using.
and I don't really understand, doesn't the Kernal comes with the rom?
Can I change it without changing a rom ?

I notice the same problem a few days ago (I think is since I have install CM10). I have switched on OrDrost since 2 days, I tried the Faux kernel and finally I just revert to full stock rom and my wifi signal haven't change :/

But on the stock rom WIFI was ok.
Update: Ok I did the "Squeeze" test. Wifi is great whn I squeeze
So it is a hardware problem?? How it only started after I put CM10?

Have you reinstalled the stock rom since you have the problem?
I don't know if CM10 is the cause, or it's a coincidence..

there's an UNOFFICIAL release at the moment which may fix some issues, though I've not noticed anything and I've had every release since A10 installed, so it could be a hardware issue.

I'm on the newest build of cm10 and my WiFi network is fine. I can from leedroid and so far just the same. I do have a tiny bit of earphone cable between my back and hard case which gives me my full bar due to the hardware fault.
Couldnt be bothered sending it back. So this works. Bit did recorded it with HTC so they know I have the fault.

Not yet, I really hate the stock rom.
tgcp, Where can I get this rom?
(Although it really seems like an hardware problem,
I heard the latest stock update helps a little so there
might be a software solution)

But if you use Cm10 without that little earphone cable, the wifi won't work good?
BTW, what does htc support ask to fix the problem? Do they care you rooted and unlocked the device?

The cable is about 3mm in lengh and as i have a hard case, its enough to compress the connection inside the phone where the fault is.
Htc would of course fix it, but whats the point if the phone is working and its not noticeable.
I would have had to relock bootloader and go back on stock rom.

I can't move more then 2 meters from my router or it disconnects.
Does your wifi issue not that bad? (without the cable's help)

With out my fix the signal is a joke. 1 bar when 3 feet away. Wasnt usable.

Problem is I can't get back to stock! from what I understand the Stock RUU for my phone wasn't released ...
Do you think HTC will be "understanding" and fix the wifi issue even with a custom rom?
(they'll know anyway that I opened bootloader)

Try flash the Rom with the stock kernel, that will surely solve the WiFi problem.
Sent from my HTC Desire C using xda premium

Did you not do a backup before installing custom rom. Im positive that even if you relock the bootloader they can see that if they went in to recovery. But unlikely. So if you flash stock rom and re lock bootloader, remove root you should be fine

Hi, try using tbaldens CM10. It can be found under HTC ONE X ORIGINAL ANDROID DEVELOPMENT. I found this to be the best CM10

I have been chasing this problem ever since installing CM10 on my Evo 4g LTE. I was getting 4 times the wifi distance on the stock rom. I go about 30 ft. outside the office and wifi drops. Also, what is the most annoying... I stream over our LAN, and when the screen is off, it turns wifi off after a few minutes. (and yes, the check box is checked to keep wifi alive). I've also tried all of the wifi fix apps and none work. If I leave the screen on and stream........ it is good anywhere from 1/2 hour to an hour, then it will just stop. This kills my battery of course. The problem 1st occured when I first bought my OEM 4g lte, but there was an option in the advanced menu "best wifi performance", after checking that, it worked great, then I switched to CM10 and I now have the wifi issue, and there is no option for "best wifi performance". I've tried a couple other jellybean roms and they have the issue as well. This is driving me nuts. I hope someone finds a solution. I don't think the average person would find this as a problem, but when I stream over the net and move all about the shop, it is unacceptable.

I faced the same issue but not on any other ROM. It was specifically with Cyanogenmod 10. I was upset because it gave me the best results but the wifi result was really poor.
However, since I work with wireless networks often, I decided to explore Cyanogenmod's wifi settings. I noticed that if you go in the Advanced Wifi functions (which you can find in the Wifi options menu) you will notice that there is an option called "Wi-Fi Region Code".
Apparently, this option allows you to select the frequency bands your device can operate and is subject to the different world regions. It is quite possible that your Access Point follows the regulatory body of your country and you should know which frequency bands they allow the AP to operate. Due to this it may be just that the Cyanogenmod, by default, put you in a different regulatory domain and limits your frequency band to a subset offered by the AP. Hence, this effectively limits your wifi reach even if you are sitting right next to the AP.
I chose "Japan" since I remembered that their regulatory domain allowed for quite a large subset of frequencies that are allowed on the WIFI spectrum. This immediately increased my received signal strength and I did not have any problem since.
I suggest you play with this, it is likely that your android device will start functioning correctly. However, if you are facing this limited frequency issue on more than one device and that too running different operating systems and different wifi hardware...chances are that your wifi router is malfunctioning. In that case, replacement or repair of the Access point is the best alternative.
Good luck. I hope this solves your problem.

[Q] Why does JB 4.1.2 not connect to wifi properly??

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.

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

HOX Crashing Wifi network

Hi Guys, im experiencing some annoying problem .
When i connect my phone to our Wireless network i got like 10 sec Internet access then it crashes the whole network. (I receive signal but cant connect to internet) . Then i have to restart my Router and disconnect my phone in order to get my Internet back.
Im using Static IPs but the Gateway and DNS are the same (idk if thats ok but works perfectly on my PC)
This problem appeared after the Jelly Bean update, before that ,it worked perfectly.
I would be very happy if somebody knows why is that happening.

Yes set your router to G mode only will do the trick. Its a step down from B or N but seems the only solution. Its a HTC issue not JB because friends of mine who have other manufactures(Samsung) phones with JB have no issues on my network when my router is set to GB and N.

Sense 5 wifi n-mode and wifi fix

Hi all
I believe the HOX has a wireless n compatible receiver..well I'm Viper ROM that has the wifi fix and I was checking the possibility of connecting to the wifi with just n-mode enabled in it...As soon as I switch to wireless-n, the phone's wifi disconnects and cannot connect again to the modem...All my other devices connect well even in this mode...So the question really is does the wifi fix really fix anything? It doesn't matter which ROM I'm on...I have to check with the pure stock ROM to see if the wifi works then...
