Yesterday, i have unlocked and rooted my phone to put CM9 nightly on my galaxy nexus[GSM]. Everything works fine but i have one issue, the wifi speed is really slow on my phone.
this is the rom that i flashed on my phone.
http://forum.xda-developers.com/showthread.php?t=1398495
I have tested on speedtest.net and i am getting less than 0.5mpbs. I have looked over my router and other devices, they are getting 5mpbs. Is this an issue with CM9? On stock settings for the nexus i get 5mpbs.
Is there a fix around this?
What is your broadband connection rated at? 5/10/15/20...mbps? If you are rated at 15 or 20 and your only getting 5 on other devices you could have a router issues.
Does the speed get any better when you are within 5 feet of the router?
Do you have multiple Wireless Routers/AP's?
there is no difference if i am beside or 20 feets away from it. I still get less than 0.5 mpbs. There was no issue when i was using the stock version of GNexus 4.0.2.
I only have one router.
I have managed to fix the problem, can a mod please delete this thread?
I have the same problem. When I restore back to stock, the problem goes away. I do have the FD01 radio firmware installed.

How did you fix it? You could at least share it with all the people who tried to help
Hi folks
I was having the same problems. I just upgraded to 9-20120511-NIGHTLY-maguro and my wifi issues have gone.

Try rebooting your router. I've been using CM9 for weeks now and the only time I've had issues were with my router.
This isn't even the fastest.. just a random test. CM9 Nightly 5/11.

I have the same problem after I assigned my phone a static IP on my home router. Search on MAC randomization for this issue. There are several kernels that fix this. I believe Franco, Trinity, and Imoseyon will work. I wish the stock cm9 kernels would get fixed for this issue.
Sprint GN, Tapatalk
Do you have some sort of QoS setting on your router keeping it from providing the speed to certain devices or something like that? I agree with the others, first thing I would do is factory reset my router.
Having a similar issue my epic is doing 25mbps on a 30mb line but both of my gnexs on different roms are only getting g 10-12????

I've also noticed that my Wifi performance is seriously degraded and very slow. At first I thought it was my connection, but further testing narrowed the issue to my Gnex only. I get very long 1000+ms ping times using the speedtest app and get a stuttery 1-2mb/s down and up, when every other device in my house (6+) is showing upwards of 20mb/s down and 2mb/s up. I have replicated the horrible ping and download times from various wifi hotspots.
To test further, I reverted to a backup nightly with no change. I went back as far as my 04/29 build and the problem remained. Maybe I just didn't notice it before, but I'm not certain. I have even flashed other ROMs such as AOKP and speedtest showed superfast results.

Wonder what AOKP did to it because myself and many others finds wifi to suck on the stock roms.
The wifi problem goes away when i use a kernel that addresses MAC randomization.

Figured out the cause of the slow wifi
I found out what the issue was with my wifi slowness and awful ping times.
I re-installed the latest Nightly and this time I did a "wipe data" (wiping out all of my apps) and my speedtest results were awesome again. Essentially a clean install. After reinstalling my apps one by one, I've been running speedtest each time and found that Doubletwist/Airsync was the cause of my slowness. Uninstalling DoubleTwist/AirSync and then rebooting fixed the speed/ping issue right away. HTH.

You could also try AirDroid (https://play.google.com/store/apps/details?id=com.sand.airdroid) as an alternative to upload/download files to your phone.
Works great for me ^_^
Wtf? This started happening last night.. When ever the screen goes off, or if i press the power button to turn off screen /block phone, the wifi turns off :S
Im on francos kernel and his app updated last night.. Dunno if that is causing the issue

I'm experiencing the same issues along with random 3g/h data loss's as well. I'm using faux's 17m kernel. I also upgraded to B36 and did a full wipe and am still experiencing these issues.
I have a wifi problem as well, but mine is that it won't connect. It turns on and all, but just doesn't connect to my router. Laptop and PS3 connect fine, but nothing to my Gnex. However, it was working fine this morning, last time it did was at 8 am. Any ideas?

Bad idea to bump this old thread lol.. I figured that i can not use wifi keep alive app and turn on the keep wifi on native policy at the same time.. Is you do so.. The wifi goes crazy..
As for your issues try flashing a different kernel?
Galaxy Nexus AOKP m5 Franco kernel m3
I've now tried several kernels (Faux, Morfic, Popcorn, Stock) and no matter what wifi won't connect. I have two routers in my house, one is a wireless N and one is a G. My Gnex won't even recognize the N router...
As much as I LOVE AOKP i've gotta to to CM9 until this is fixed.

Do you have security on your routers? If so, read the thread I started about it.

Is anyone else experiencing this? This has happened to me with a couple of different roms; sfhub's rooted FF18, datajosh's FF18 rooted deodexed rom, and PhantomHacker's ICS FF18 Blazer rom. After I flash a custom recovery like agat's or chris41g's my wifi start not working properly. It will connect fine and work for a little while. I haven't quite pinpointed when it stops working, but after sometime the wifi will just stop bringing down data. This may be happening when the phone goes to sleep. Regardless, it will be connected to the router, but no data is flowing. I need to turn off and then turn the WiFi back on to get it working again. I've tried changing the wifi to disconnect when the phone is asleep, that sort of fixes things, but I'd rather have my phone always connected.
So, do other experience this? Is this a common problem I just have to deal with? Is there a thread somewhere that I'm missing that will help me fix this?
Right now, I'm running an the AOKP milestone 6 rom that came with the TWRP custom recovery and wifi is working properly, but I'm thinking I want to go back to a TW rom but want to figure out this WiFi issue. Any help would be awesome. Thanks!
I'm having the same problem, but only on my home network as far as I can tell. I found a thread elsewhere that proposed it was a problem with using WPA PSK encryption on 802.11g networks and a bug with ICS. The suggested solution was to change your encryption to WPA2 PSK. I did this and thought it fixed the problem, but it has returned a day later.
This doesn't happen when I'm at work, so I think it is some setting on my home network that ICS doesn't like.
I also experience this problem. I'll try messing around with my router tonight. I feel like I also don't have problems at school. So its worth a shot. I'll let you know how it goes.

So, I actually wasn't able to mess around with my router last night. But I'm wondering if this could be a router issue and not a security issue. Out of curiosity, what kind of router are you using? I'm using an old WRT54GL that I really like and suits my needs fine. I just can't believe out of everyone on XDA with an E4GT that most everybody isn't running WPA security of their routers. Similar to you, when I'm at school I'm not experiencing this issue. I'm wondering if I should buy a router from Walmart or something and see if it fixes the issue, return it if it doesn't. Thoughts?

I'm experiencing the exact same issue after loading the FF18 OTA update from stock recovery. Factory reset after update did not correct the issue, Sprint support has not been overly helpful- and went as far to say that correcting the issue may require replacement of the phone, and that I shouldn't accept the ICS update on the new phone if I go that route (not doing that).
Possible Solution
Okay, today I swapped out my wireless router with a dual band wireless N router from netgear. I've had it installed for a couple of ours and so far my WiFi on my phone is working as it should. I've made no changes to my phone. So, this may be a router issue. I don't know anything about hardware, or why this would be happening, but this may be a solution. I'll post an update if the WiFi ever acts up again.

I apologize for resurrecting this thread but, for posterity, i'm also running a WRT54GL v1.1 and have the same problem on two different E4GTs running FF18. I have tried the 4.30.15 cisco firmware after factory reset along with tomato 1.28 (with different SSIDs), both had the same issue (i.e. wifi seems to 'hang' after a few hours. the notification bar shows the wifi signal strength, as well as being connected, but unable to do anything online. this issue only appears to happen when using this router.), which suggests a possible hardware incompatibility. the current fix is to diable/reenable wi-fi, which will work again for a few hours. The router works perfectly will all other devices.
I will poke around a bit tonight and post results if I find anything
UPDATE: I apologize for the wait, but may have a workaround. The phones have since been updated to FH13 and both still had the same problem.
I'm currently using Linksys/Cisco firmware Ver.4.30.15 for my WRT54GL v1.1. In the wireless security section of the web interface, I have changed the security type from WPA2 Personal to just WPA Personal. No other settings were changed. Just to rule out a DHCP issue, I set an IP statically on the phone but this may not be necessary. Since the change I have not had the "connected but not really" problem as described above.
I have had a limited time to test the change, but if the problem persists at least it's an improvement. I will keep the thread updated with what I find.
Yes please keep us posted if you find anything with the settings on the router. i have the same router as you ther WRT54GL and I am experencing the same wifi connected yet disconnected bug. Have to turn it off then back on to make it work right.
I have the same issue. Not sure what the issue is but I never had any problems on Gingerbread.

+1 I too never had any issues with GB 2.3.6. The wifi problem started with ICS FF18 and now too with FH13
Hey everyone, just came over here from the HTC One X ( AT&T ) forums, smashed the screen on it and used an upgrade to get an AT&T SGS3, loving it so far. Had it rooted and custom recovery, and was on a custom ROM not even an hour after getting home. Anyway, onto the main part of this post.
I tried CM10 ( the 11/01 and 11/02 nightlies), both of the AOKP, and LiquidSmooth, and on all of them, my WiFi stability is not there. It seems to disconnect at random, if connect at all, and when i walk out of range of the router, and then come back, it will not automatically reconnect until i go into airplane mode. Trying to turn WiFi itself off and back on does not work - it won't turn off/back on, it sticks at what it was at.
TouchWiz ROMs, everything works just fine. I'm pretty sure it was working on MIUI as well, but i didnt have MIUI on there long enough to properly test it.
I am using the UCLH9 radio, since AFTER searching the forums pretty in-depth, i found that all radios prior to UCLH9 had wifi driver issues. Flashing this new radio did NOT fix the issue.
I have tried both stock CM10 kernel AND Ktoonsez's kernel (which is pretty freakin awesome, btw! :good: ) and still have WiFi problems.
I have tried flashing ROMs through both TWRP and CWM Recoveries, and have done a full wip of /system /data /cache and /dalvik-cache 3 times each before flashing a ROM.
I'm a pretty competent at flashing ROMs and troubleshooting problems, I am a pretty well-known beta-tester for multiple Sense and AOSP ROMs over at the One X forums, and I have a very good knowledge of how to work ADB and Fastboot. I've been around XDA for a little while, and I know the way of things around here. (don't want you guys thinking im just another a$$hole that threw a post up the second a problem occurred without doing some research first!)
If anyone has ANY ideas as to what may be causing the wifi drivers to crash, PLEASE fill me in.
I've tried all the same things you have and have had no success. The best wifi stability I got was the AOKP_d2att milestone1 w/ lean kernel combination, but wifi would stay connected for 3-5 minutes as opposed to 30 seconds.
I briefly tried CM9, but that still had wifi issues. I might try a few other ICS roms
I came across these threads that documented the problem across other phones:
code.google.com/p/android/issues/detail?id=34942
code.google.com/p/android/issues/detail?id=36993
I've decided that I'm stuck with ICS until the official JB comes out.

Well, I flashed Intergalactic, which is a modded Stock ICS TW ROM based on the AT&T firmware. Shortly after, I reinstalled TWRP recovery and flashed task's AOKP with ktoonsez's kernel, and WiFi works!
This is similar to an issue we had several weeks back with CM10 based ROMs on the HTC One X, you couldn't get LTE unless you flashed a ROM based on Android 4.0.3, it was something with CM10 obviously, because it was fixed in one of the October nightlies iirc.
Try flashing intergalactic and then task and ktoonsez aokp and see if your WiFi is working and let me know
Sent from my SGH-I747 using Tapatalk 2
Nope, no luck this way either.
Wifi under Intergalactic works fine.
TWRP flash AOKP milestone 1 alone, with the ktoonsez kernel, or with lean kernal and my wifi still hangs after ~1 minute of inactivity. The phone grinds to a halt. If you can get to the settings, it says that I am connected to my router, but shows no signal bars. If you can then turn wifi off, the phone un-freezes, and (except for no wifi access), the phone is back to normal. If you now turn wifi back on, it stays up for another minute or two and goes down again.
I'm open to any other suggestions.
Thanks though

i am using task and ktoonsez rom....when i first installed it, i noticed wifi dropping, it was annoying.
kinda dont happen anymore. The only 2 things i can think of that might have helped me is; i flashed a new modem i747MVLLE8(I'm with rogers), and under Wi-fi(menu/advanced), i unchecked poor connections.
also my router is 2.4ghz and 5ghz band, but i am connected to the 2.4ghz band.
hope it helps somehow.
I had horrible dropouts and speed with my last WiFi router. I forget the name/model but it was a new model (released this year) that had great reviews.
I went back to my old router and all my wifi problems disappeared.
I do get dropouts once in awhile still. But I haven't done a clean ROM install in awhile.
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. :/

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:
