[Q] Wifi Tethering issues, anyone else having any?

Hi,
I'm an Android user for more than a year now and ever since I have the Galaxy Nexus the tethering is been giving me headaches. it seems to connect to my laptop but after a while it just stops to work. I can't browse any site or download anything from my laptop but this does seem to work on the Nexus.
I've resetted the phone to factory settings but this didn't solve it. I've also noticed that disconnecting and reconnecting to the wifi tethering helps even though I do have connectivity problems sometimes.
is anyone else experiencing the same issue?
I'm on the UK 3 network and the Nexus is not rooted and the unbranded version.

before the galaxy nexus I was using the HTC Desire (rooted etc) but never had the same weird disconnecting issue..

I have not tried it yet

Yes, having the same issues here as we speak. All the issues and fixes above I am experiencing. I'm from Australia on the Optus network.
I put my sim into a Huawei E585 and had no issue whatsoever, so seems to definitely be a phone issue....hopefully a software issue which will be fixed soon as I its extremely annoying as you know!

I'm awaiting the 4.0.2 or 4.0.3 update now, this seems to solve several issues and they also mentioned tethering in it. let's just wait it out now

I haven't received any update on the Galaxy Nexus yet, still running 4.0.1, can anyone please verify if they are having issues running ICS 4.0.2 or newer on their handsets while tethering?

I wonder if the networks have found a way to remotely block tethering access? I say this because I have an HTC Desire on Orange which will no longer load anything when using Wi-Fi tethering.
My Galaxy Nexus is fine though. I'm on the One Plan with Three which includes unlimited data and tethering (says so in the small print of the contract). I'd say contact Three if you're on the one plan and ask for their help.

Guess you didn't really properly read all messages,
I don't have any probs if I tether from my desire, I have an All you can eat data on Three,
the thing is it just stops working and I cannot ping my Nexus from my computer. according to the change log for the nexus they did say to fix some wifi issues etc with updates..
So which version are you running???

I am running 4.0.2, Samsung galaxy nexus, and tehering is not working. Anyone have a solution to this problem?
Temporary solution: (Click thanks! )
Google knows about the ICS tethering problem and this is their temporary solution.
http://code.google.com/p/android-wifi-tether/
You must "allow" you computer after you've connected to the hotspot. See this thread for more.

I am experience the same issue on my Galaxy Nexus, it's currently running 4.0.2 and Baseband I9250UGLA4.
my solution to the issue at the moment it's using USB tethering.
I suggest PdaNet, you can find it at Google Play and it's free =)
i am not using the stock wifi tethering feature on ICS instead i'm using FoxFi and at times the timeout issue will show up but if i restart the hotpot a few times, it seems to be working fine again...
i'm not sure if i am any good help to anyone but that's my experience...

FWIW, I have not had any issue with this. I tried tethering for the first time the other day with my Wi-Fi-only tablet for an hour and it Just Worked.

[BUG?] WiFi drops after a few minutes...just off/on helps - The FINAL ANSWER search

Hey my xda friends out there!
Being a pretty new Nexus owner, I´m getting crazy by serious WiFi issues over here. My Nexus can´t get any stable Wifi connection at all...as soon as I´m making up a connection, I can be pretty sure that I will loose it after a few minutes. The only way out of this is...like I knew it from buggy roms before...to switch WiFi off and on again. After this procedure, I do have WiFi again, but it´s the same situation like before...after a few minutes --> bam, I´m out again.
Well, after some research on several forums out there, I can be sure that there are some other guys, struggling with same issues as well. Some of them are just having some standby issues, some of them can´t get any wifi connection at all. But an answer to my sort of issue? No way...
So what´s the deal here? I´m on a Stock Rom, what could be the reason for my WiFi issues? Any ideas?
Would be very very grateful for some support!!

Having the same problem here. YouTube seems to knock out Wi-Fi for me. Or marketplace downloads.

My initial suspicion is on a router configuration. Do you have this issue on multiple wireless networks, or just yours at home/work? Try somewhere like a coffee shop with an unsecured network. If you don't have the same issues on other networks, I'd look into messing with your wireless configuration. My router at home gives me issues losing connection to Google's servers (gray signal bars) intermittently, and I haven't yet found a solution.

Hey copkay! Thanks for your input!
The point is:
Dell Streak,
HD2,
SGSII,
Flyer,
Touchpad,
Transformer,
Galaxy Note,
Sensation.
ALL of them worked/are working well. So this has to be a Nexus thing, or am I wrong? Maybe its working better with an unsecured open WiFi Hotspot, but hey, this shouldn´t be the main place to work (imao!)
What do you think about it?

You have too many gadgets.
But yes, that's a good question. WiFi can be finicky with some drivers, so it's possible that yes, it's a problem with the Nexus in particular. The reason I'm asking is that it's much easier to narrow down the problem when you eliminate certain solutions. So does it work properly on other wireless networks? Does it do the same? Does it drop connection entirely, and if so, for how long? Or does it simply switch to gray bars?
I certainly don't recommend switching to no network security, but if it's a particular router/setting, more information would help to deduce the problem.

I had some of the same issues with my wifi (as well as sometimes it wouldn't fully connect and would get into an authenticating loop). I never had this on my past devices though. I don't know the ultimate solution to it, but I have found some work arounds for some of the networks I frequent.
What I've found is that I've had to turn off the auto detect wifi frequency band and leave only the 2.4ghz band while other times I've had to turn it back to auto detect.
While annoying and not the desired answer, hopefully it can help you out in the mean time.

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.

Wi-Fi unreliable

Recently I've been having problems with Wi-Fi. My phone and nexus 7. They both stay on blue bars all the time claiming they're connected to Google servers. And it'll work good for about 20 seconds and then I'll have no connection for about a minute. Bars will stay blue like its connected and WiFi show that it's fill signal but pages won't load, apps will timeout and YouTube videos won't stream. Makes it impossible to download any Roms or apps at times. This just recently started happening. Videos will stream good for maybe 2 minutes tops. Then pause, after a minute Wi-Fi will stay streaming and going again by itself and stream. I haven't changed my router or is settings. I have static ip's assigned too. All other computers work just fine for internet. Never a problem.
I've tried changing kernels, Roms, complete wipes and reinstalls. Rebooted the router. Nothing fixes it. I'm getting really frustrated. I'm at the point where I'm going trio go buy a new router just cause I want to use 5ghz. Anyways, any suggestions to solve this?

There may be an error in aosp code that can cause wifi instability: http://forum.xda-developers.com/showpost.php?p=35146886&postcount=5128

Weird how it affects just my device in an entire thread with a ton of people using the rom and same kernel.
I went and picked up a new router. I'll see if that fixes it. Thanks for the input though. I appreciate it.

Didn't help with new router. My WiFi still cutting out like crazy on Franco kernel. Almost as soon as I turn off screen. But its not turning WiFi off. Just goes into some sort of state where nothing comes through. When screen on everything is fine though now.

In Wifi settings, you could try unchecking "Avoid Poor Connections" and see if that helps.
Also do you have any other devices at home on the same wifi network - do they experience the same issues, I know where I am if we get a lot of rain, it causes intermittent internet slowdowns, I had similar issues and after testing other devices found this to be my problem not my Wifi.
Also, have you got any cordless phones in the house that might run on the same frequency?
I still have an issue keeping wifi at 100% d/l when the phone is asleep, even though the setting is for always on. It must be a hardware thing for me because every rom I've tried from ICS to the latest JB exhibit the same issue. If I am in a desperate need to d/l a large file on my phone, I just temporarily change the screen display off timer to 10 minutes of so so the wifi will stay at max d/l speed.

Ya avoid poor connections is unchecked. And wifi optimization is unchecked. I've tried putting my router on full auto, tried setting static ip addresses for everything. Changing from wireless n to wireless g. Changing security to off as well. Using the 5ghz band instead of 2.4. The nexus 7 is working perfectly fine with the new router. But my galaxy nexus is totally unreliable. Weird is that it just started happening within past couple weeks. And actually, it was good for the first day or so after new router. I can confirm all other wifi devices jn the house work just fine without any hiccups. I've never had a problem with other devices. No dropouts or anything. It's really puzzling me!
One thing I found weird, if I disable wmm on my router, my nexus 7 and galaxy nexus will not connect. Anyone else get this?

I hope you also have your router firmware completely up to date.

Ya my router auto updates itself. Its a Cisco EA6500 in case your wondering and is helpful.

I use my wifi at work and it's very unreliable. At times going into an endless disconnect/reconnect loop. Sometimes restarting the wifi helps or putting it in and out of airplane mode. Other times nothing helps except a reboot of my phone. Some apps may make the issue worse. I don't think there is a fix and waiting for google to fix the flaw a user pointed out earlier.

Possibly a 4.2 issue. But its not affecting everyone it seems. But i see that there is a huge thread about this at the google site. Not an isolated case

When you say you set a static ip, you set one from the router, have you tried setting a static ip on the phones wifi advanced options as well?
Have you tried different radios?

Yup has happened to me mine connects to the net but has grey bars and doesn't open any websites and apps dont connect to the net a reboot solves the problem

I set static on both router and the phone. I've tried all the north american radios. None of the euro ones. no effect. Sticking to the latest North American radio for now. I've managed to make it work sorta with CM10.1 with stock kernel on completely fresh install. It works, but the down arrow on the Wi-Fi icon stays lit almost 100% of the time. no idea why, only other device that was on all yesterday was the nexus 7, and that was on the 2.4ghz and phone the 5ghz. Huge wlan_rx_wake!

It's likely this:

See if that sounds about right and if so, you'll just have to wait for a Google Patch.

When i first updated to 4.2, I was getting crazy dropouts. After unchecking the Wi-fi optimization, it was more consistent but still drops out frequently while at work. There is a known bug with the wifi driver that hasn't been addressed for years, but still trying to find the original articles describing the problems.
It seems you are having tons of issues, worse than most.
If you are having a problems suggested on this site, maybe this can help.

It affects me as well. Completely random. Everything appears fine except that instead of blue, the icons are grey. Turning off wifi and turning it back on fixes it.
In the link above, there is a comment where you can submit more info for Google to help solving the problem:

the weird thing is, it just started happening about 2 weeks ago. It was perfectly fine up until then. Never had an issue with Wi-Fi. If this don't work i might try doing an entire wipe right back to stock and locking bootloader.

[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.

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 :/

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. :/

I have had those wifi problems with every android version and rom I had on my GNex as far as I can remember.

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.

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?

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!

Temporary solution
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:
