Hi,
I am having problems with wifi drops under custom roms (I've tried several CM10 builds and AOKP's JB Milestone 1).
Under a rooted stock rom (UCLH9) and ATT installed kernel (3.0.8-985684) I get a very stable wifi connection.
However, if I install a different rom via ClockworkMod, I'll get wifi connections for ~ 30 seconds (or until data stops transmitting), and then it will drop out. I have to cycle the wifi on and off to re-establish a connection. Again, I'll stay connected for 30 seconds or less and wifi will drop again. The rest of the phone works fine.
Despite the dropped connection, the wifi icon (under settings) will say connected but show no signal bars. In addition, the phone nearly comes to a halt and hangs, as if all processes are being devoted to reconnecting.
This happens on at least two routers (one at home, one at work), so I don't think it is a router issue.
I've seen some people talk about the *#0011# dial code to turn off wifi sleep mode. If I dial this under the rooted stock rom, I'll get the menu as expected. But if I dial this code under either custom ROM first I see "USSD code running" and then I get an error "Connection problem or invalid MMI code."
If, after all this, I restore to the rooted stock ROM, wifi works and everything is fine.
Any suggestions for getting a wifi functional custom ROM installed would be appreciated.
Thanks

Sometimes getting a kernel for those type of problems fix it because they are basically replacing your phones access to your drivers (Wifi and so on)
This one puzzled me for a while. The rom comes preset to disable wifi after a certain amount of idle time. Go into Settings>Wireless & Networks>WiFi then press your settings button>Advanced> Keep Wifi On During Sleep> Set to Always. Maybe this is the fix to your problem.
This is happening to me right now with my LG G2, WIFI is stable on the stock rom but drops constantly with any custom rom. Did anyone find a fix for this?
I have tried several fixes including WIFI on during sleep to always, WIFI optimization off, different freq bands, I can't figure this one out...

If I don't enable data, the phone works fine. I can receive and make calls just fine.
Once I turn on data connectivity, data works fine for a while. Like 40-45 seconds. After that, the connection sort of gets stuck. I cannot make any calls, and if I call my number, I get a 'not reachable' message. The indicator in the notification bar will show full bars for a while, then if I got Settings >> Wireless & Networks >> More >> Network operators to do a manual search for network, the status bars drop to zero, become an 'x', and then go to full again. The behavior then repeats.
Bootloader is unlocked.
Any kind of help will be appreciated.
If it helps, I have the NTT Docomo version of the Galaxy Nexus (SC-04D) that is sold in Japan, but I live (and use the phone) in India.
Are the APN's set up properly for your carrier?
I'm assuming you've tried the usual toggling of airplane mode and rebooting, etc.?
APN is setup correctly, which is why the data connection works fine for a minute or so.
Toggling Airplane mode often does nothing at all, since the cellular connectivity system seems to be stuck, even when it does, it takes a loooong time for Airplane mode to get enabled in the first place, and disabling it takes even longer.
Rebooting the phone fixes the issue, but it returns very quickly (within a minute or so after rebooting).
Also, another similar thread over here mentioned that their problem got solved by flashing the FuguMod kernel - http://forum.xda-developers.com/showthread.php?t=1438417
I flashed the kernel successfully, but the problem still persists.
Mine is doing the same thing. I'm out of ideas.
i'm starting to think this problem is extremely common.

i believe those thread is about same problem (or variants)...
it will be really useful if everybody was under same thread! =o)
I ROOTED and unlocked my phone as soon as the option was available. Afterwards I entered the *#6335623# to change the wifi popup. Ever since I've had to manually connect the wifi to the closest signal. I've tried to use the same *#6335623# code on the dialer but it doesn't come up any longer. Has anyone had this issue because I haven't seen it posted anywhere.
I'm running Aokp on the latest vrlhe radio.
Does anyone have any ideas. It seems that it now not only doesn't auto connect to closest wifi, its starting to say that all the connects are poor signals even when 10 ft away from the wifi box.
Uncheck the poor signal option under advanced settings, and see if that fixes it.

Hi all
A search of the forums revealed 5 potential threads similar to this but not quite (not same symptom, phone, modem ...)
Keep loosing mobile data connection...
I have installed X-note 3 and found that my mobile internet is intermittent particularly in Youtube where I frequently have to click "No connection , Retry" or "Connection to Server lost, Retry" and in Play Store and Gmail where the problem tends to occur on a screen unlock after it has been unused for a few minutes - about 3 to 5 mins.
I dont believe this is a ROM issue because I d/l various ROMS such as Revolution, Alliance, PacMan, Paranoid and still I get the problem.
I tried installing all 9 of these radios here: http://forum.xda-developers.com/show....php?t=2044937 to no avail.
Also notice that if I set Network Mode to "GSM only" then this makes no difference to the problem (the default is "GSM/WCDMA Auto" which is what I've set it back to)
WiFi works fine.
Any ideas?
same issue here.
a lot of time trying to know why this happen. and i think it is due to fast dormancy.
the phone usually stays in standby in 3g... when you request some data it will automatically turn h or h+. Here is when you will notice the internet moving.
But unfortunately if you have some.coverage issues you can have this problem and then the programs instantly report no conection. If you insist you will see you can obtain connection. 5 seconds later 3g will appear again
It does not mind you will see the bars of coverage at maximum... if there is no quality signal you will have this problem.
I just have this problem at work. Not in other places.
But if you want a constant connection I recommend to keep for example online music while navigating...this will avoid the issue...unfortunately you will increase your data plan..
Yes!! This is exactly what happens.
So it can't be my specific phone but perhaps a hardware design or software issue. I don't recall this I happening before I rooted
Weird
Fixed it - so far at least
Fast Dormancy is the problem. It was enabled by default and I have turned this off. The connection is now fine and seems to be "always on". For me this is okay because I do not have any data limits or pay per MB for data. I do notice that new connections take a little longer to start (for example, time taken to access internet when opening up an app that is not currently running) . This is not noticeable for apps already running (in the background)
This explains ....

Hi All,
I am still lumbering on with an old HTC Desire running CM 7.07282011-Nightly and have had no real issues up until a couple of days ago.
Whilst in France (not that that make a lot of difference) the Wi-Fi access stopped working and the phone stopped being able to see any Wi-Fi networks. Basically, it switches itself off after around 30 seconds and cannot pick up any networks. In addiiton, the WiFi MAC address shows as unavailable although teathering via a WiFi hotspot works fine. I was switch between teather and normal Wi-Fi when the problem occurred.
If I go into Settings --> Wireless and Networks -->WiFi setting, then switch on the Wi-Fi, I get the "Turning on" message but then a Sorry warning saying "Application Settings (in process com.andriod.settings is not responding" and I can either "force a close" or "wait". If I wait, the Wi-Fi will simply switches itself off after about 30 seconds.
I did read in another post that this might be to do with the Wi-Fi sleep status but I tried all 3 options (from the menu in the Wi-Fi setting page) but that didn't do anything.
The issue appears to be that that phone has lost the Wi-Fi adaptors MAC address (says unavailable). However, I can still use Wireless Tethering and connect to to the phones WiFi hotspot. I think something has go screwy with the Wi-Fi tethering and Wi-Fi access (as I was switching between both when on my travels), but I need some help in trying to fix it.
Any Help Welcome
Chris
I tried updating to cm-7-20130301-NIGHTLY-bravo (whuch was the last release version), but still no joy.
Any help welcome
Well, after trying pretty much everything, I had to run a factory reset on the phone. Finally, my Wi-Fi is working again. Of course I now have the ball aching job of setting the phone up and re-installing all my apps again. Google restore is pretty rubbish
Looks like there must have been a config setting that got screwed somewhere. I did take a backup of the ROM and if anyone knows where this might be resolved, I wouldn't mind restoring.
I have a peculiar WiFi issue in my office where I can connect to the router, however, I immediately receive a message: "internet unavailable". I am using latest stock T-Mobile ROM. 5.01, Build 20E. Other phones have no problem like my Nexus 5 or other people's iphones. Also, I am running a dualboot partition with a nightly on the same phone and it works fine in Cyagenomod.
I've tried this app: WiFi Doctor, and it finally worked until I went out of the office for a few minutes. When I came back I was at square one and what's worse, WiFi Doctor couldn't cure it any longer.
Anyone? Hello? I'm pretty sure there are a few smart people out there.
T-Mobile G3 stock ROM, Android 4.4.2, build D85110m, encountered the same problem in my office. Likewise, no issue with an old Samsung or iPhones.
From what I've manged to find on the internet, IPv6 or the MTU setting might be a contributing factor.
This isn't a fix per se, but voodoo steps of forgetting the network, switching off wifi, switching on wifi, re-connecting to network (staying on the Wi-Fi screen and waiting to see that it connects) works sometimes. Sometimes it fails and tries to re-obtain an ip address and it works after it re-tries several times. All this while I would be on the Wi-Fi screen watching it.
Occasionally, rebooting the phone helped for a while.
All the boxes under Advanced Wi-Fi are unchecked for me.
My G3 is not rooted, so I've not tested to see if disabling IPv6 or changing MTU fixes it. If you (or anybody else) do test it, I'd appreciate it if you could post your results.
