Impenetrable WIFI Sleep Problem - Samsung Galaxy Nexus

After checking couple of forums, I realized that this is a general bug for Android. Many people complain about it but it seems nobody could find an exact solution. I will try to explain the problem to be more precise.
Even though "Keep Wi-Fi on during sleep" is checked as "Always", when the phone goes to sleep it doesn't connect to internet.
Wifi signal shows it is connected but it is not. I have to disable/enable wifi in order to make it work.
You can see many posts regarding to this issue. It looks like people acquiesced the problem since nobody found an exact problem.
Is there any solution that you could find?

I have GSM Nexus also.
I bought it 3 days ago. I noticed it right after I powered it on. I had similar issue with my HTC Desire.
Now I installed a ROM to try it and still no luck. I started to think that problem is because of modem.
What ROM & Kernel are you using?

This happens to me. I picked up some gameloft games in the 99 cent sale and downloading 800mb over wifi is impossible. The screen turns off and the download fails.
I found I have to set the screen to stay on when on USB, plug it into a wall, and download.
I've been on several roms. I haven't started experimenting with kernels but thats the fix I think in this case. Even CM roms do this. Hopefully it isn't hard coded into the hardware.

You could set your screen sleep policy to wait 30minutes to turn off. Surely wouldn't take longer than that.

+1...downloading game loft games is not possible. The game only downloads on wifi but the download stops after the screen goes to sleep.
Edit: Just tried downloading 300mb of game loft game data and it works even when screen is off. Im on AOKP BUILD 17, I definitely had this problem on stock 4.0.2.

I had the same problem with my stock rom. I still have problem. I didn't try any other rom until now. I think I should give a try.

I am my second Galaxy Nexus due to other issues. The first one did not have this wifi sleep issue, but my current GN does ( I installed a VOIP app on the second that was not on the first... not sure if this has anything to do with the wifi sleep issue). I think I may have found a work around. I changed the setting to never and tested a few times. Then I changed it to always again and now wifi remains on while the phone sleeps. I have tested it a few times and so far it is still working. I will update the post if the problem reoccurs.
Stock ROM (4.0.2)

You know what,I have the opposite issue.my wifi never shuts off.... I just leave it.wifi on this is way way way more battery efficient than my galaxy s. Even the cell radios are pretty awesome. Hardly take any battery at all.

I updated my kernel and its fixed. Downloaded MC3 finally.

[Q] gps issue on juggernaut 4.1

Sorry in advance if someone has asked this already but its hard to go through all the posts on your phone lol. Anyway, when i first got my galaxy s2 i was impressed at the vast improvement that was made to the gps from the vibrant that i had but since i rooted and flashed the juggernaut Rom onto my phone i seem to be having the gps issues again. Either the phone won't find my location or it'll locate me but then sit on the "searching for gps" screen forever and never get to the turn by turn directions. Has anyone else experienced this? Any known ways to fix this issue? Any insight would be great. Fyi, I've tried using the app "faster fix" and it did nothing.
Thanks
Josh
have you tried factory wipe then reflashing juggernaut ? and leaving it for 10 mins? also ur tryin gps outside?

I've noticed this issue. For me it just takes a LOT longer than it used to to connect. I used GPS test and it finds PLENTLY of satellites just for some reason it takes around 3 minutes to connect to them whereas before it would be an almost instantaneous connection.
Download the app fasterfix (need root access) and then just select your regin it will work better and lock almost immediately

GPS not switching on

Hello
On liquid smooth rom 1.4
Franco stock kernel that came with the rom.
I9250xxla2 baseband
Here is where my problem lies.
The phone is marugo bought from Google play running stock ics 4.0.4.
When I first got it, I never got a lock on GPS, having tried gmaps and GPS status and toolbox.
I thought it was a rom issue, so I rooted my phone and tried slim ics, cm9 nightly and liquid smooth rom finally settling on lsr because I found performance to be better; I'm sure there are better roms out there.
My GPS icon NEVER blinks. It just sits there saying "searching for GPS". I have gone up to the roof and sat there 30+ minutes but the icon never blinks, let alone showing satellites and locking.
How do I find out whether the GPS module is busted or not? I have gone through a few agps patches and fixes by replacing or flashing from cwm recovery.
The phone has only been used 2 weeks so I'm covered by warranty I suppose.
Now who out there can give me a solution or point me to some forum that has some.
I had no problem with my old phone, i5700. Side by side, that finds and locks gps in 2 seconds from my balcony.
The phone is otherwise great, just that the GPS issue is giving it and Google a bad name

I've moved on from Liquid. Just Google file name, or try rootzwiki http://rootzwiki.com/topic/20429-aospliquidsmooth-ics-v14-rom-5182012/
GPS icon blinking is AGPS right?
No it is not blinking at any time.
I got hold of the GPS fix liquid 125.zip and flashed it, formatted cache and dalvik just to make sure. Was out 1 hour and nothing, no activity at all.
Sent from my Galaxy Nexus using XDA
nope. the patch has not worked. gps has been on for the last 45 minutes. no satellites.
anybody else with any other solution?
try the GPS fix patch, AND the FasterFix app to select your location

I have tried that too and no luck with that too. Is there a secret code for GPS test?
Sent from my Galaxy Nexus using XDA
sorry to state the obvious - have you tried it outdoors?
If after all this it isn't working I'm sure it is safe to assume it is busted.
"Long is the way, and hard, that out of hell leads up to light."
yes I have. On the roof, in my car. At the same time i have another Samsung phone, Spica which happens to lock in 3 seconds.
What happens now, is that the icon blinks, but no satellite

WIFI issues since 4.2

Well the battery drain thing is driving me crazy, but another thing is this wifi issue, it will endlessly disconnect and connect, it does this all the time, disconnecting about every 15 seconds and connecting back again.
Anyone else experiencing this behavior?
Guess that you've got your answer to your battery-drain-issue! But I haven't had these issues, maybe try a full wipe and reinstall?

Op, experiment with your router's Wi-Fi settings, if I'm not mistaken there were some changes on that (encryption algorithms i think).

Seems like I spoke too soon, after a reboot to the Router all is well. Sad though that I did a full wipe before realising that..
Well glad that you found the solution! Yeah, that's pitty but the bright side about it is your phone is cleaned up now

4.2.2: Bluetooth won't turn on

OK, I have Odin'ed twice, and wiped the poor little phone so many times I'm gonna need to use Desitin. It does not matter, I have pretty much tried every 4.2.2 ROM out there, and although I have had one or two that I could initially get bluetooth to turn on, even those would fail to do so after a few hours. I've tried rebooting with it on, rebooting with it off, does not matter. The last few AOKP and CM nightlies as well as Jedi, it will not even turn on. I have seen a few folks state somewhat similar issues, but I am getting that it is not pervasive for the community. Does anybody have any ideas as to a fix, or, even any ideas as to what causes it, so maybe I can play around with whatever and try myself? Or, best case-scenario, did anybody have the issue on ROM ABC and discover that by switching to ROM XYZ it was fixed? I'm not updating my sig because it changes multiple times a day anyway, but I am back to CWM 6.0.2.7 from TWRP if that variable matters at all. Same situation whether on stock, Cerux or ASD kernel.TIA...

I works on the 2/26/13 Nightly of CM10.1. You wanna try and clean flash it? If it doesn't work then it's just a problem with your phone hardware instead of the software. Might be a buddy bluetooth adapter or such.

Fingers crossed, so far so good. I reinstalled Rootbox which is awesome. I changed from CWM back to TWRP and also installed Cerux 1.42 which in the thread made mention of the bluetooth issue being fixed, and being kernel, not ROM related. I am using crossbreeder which makes things crazy fast. I saw the "nos script" in some thread but couldn't find it with a Google search. Do you have a link for it and what exactly does it do?
Edit: Crap. it went away. Oh well, back to 4.1. Hellybean it is. I just don't get it. BT works fine on any 4.1 or ICS ROM. Only thing with 4.1 is music skips in my music player but I can live with that, I can't live with no BT. Thanks for your help. Maybe when source drops it will be all good.
Does ithe bt button turn on then instantly off when you press it? This happened to me and i went into recovery and wipe dalv n cache.. Worked perfectly after
Or i saw this post. Not sure if itll help

Well, what seems to happen is it is fine for 15-30 minutes after I've freshly installed the ROM, then it just turns off. When I then try to turn it back on it hangs at "turning on" and then goes back to off. At that point when I click "turn on", it doesn't even move. I'm a gonna try the fix, nothing to lose at this point...
Nuts. It fast moves to on and immediately goes back to off. White flag, thanks to all.
Apply the fix and delete all you devices then try turning it on and off with nothing on it...if it works then add devices one by one...if you have devices married to it the patch might not work also I think my computer dongle was the culprit

Has anyone had any luck with this? I've tried various combinations of different 4.2.2 roms and kernels and have the same issues described in this thread with all of them.

I found one thing that at least gets it working again without rebooting is to activate airplane mode. Its faster than rebooting. Wish I had a better answer...

Strange behaviour you think only your Gnex has

I browse xda alot and stumbled up on many weird issues.
Maybe this thread could be an advise-thread like "don't use your Gnex with a Netgear N Wifi AP"
If there is no interest in this thread, just let it die
This is not a thread related to a specific ROM. More for flashaholic people like me who encounter little issues that occur on many different ROMs.
I will list my issues so you get an idea why I started this thread:
- If I connect my Gnex to the charger and use it, almost every time PIE will break and I cant navigate anymore (AOSP-PIE) - I have to reboot my phone.
- If I connect my Gnex to my schools WiFi (CISCO Hardware) I have constant data-download activity and my battery drains in no time
- Sometimes if I connect my Gnex to the charger it behaves like it gets plugged in and out very frequently
- At home, connected to my WiFi (Netgear Router) I have to constantly wake my Gnex to receive new messages (Whatsapp, Mail, etc.)
Maybe we can help each other with tips?
- cheers
I have none of these issues but one. The last one. I thought I was the only one! It happens randomly to me.. I tried to find a fix but havent come across any. Nice idea for a thread it helped me already

I have not faced any of these issues. Been changing ROMs ever since the day I bought the phone (A year and a half back).
That charging issue alone cropped up once. But I was able to fix it by pushing the pin in the charging port up by a bit using a safety pin
1. My volume down is busted. Pressing it on normal mode, nothing happens. In Safe Mode, it works though I have to press real hard. Due to this, cant do screenshots anymore.
2. I can connect this gnex to my computer fine but the phone does not detect the charge.
3. Much much more wakelocks when using original battery compared to a china branded replacement battery

well, that's interesting! I'm planning a replacement because my phone is two years old and so is the battery.
While using certain kernels with Trickster Mod and "set on boot" option, I get a reboot if the screen is off when Trickster applies it's settings. Took me a long time to figure this out. If the screen is on when Trickster applies kernel settings it works just fine. Never could figure out why this happens, but I use tasker to keep the screen on for 2 minutes after boot to prevent it.
