Wifi issues on CM9/CM10 - Galaxy S I9000 Q&A, Help & Troubleshooting

Hi,
first of all I want to thank all of you pushing the SGS to the newest level of smartphone software.
Here is the problem:
I installed CM9 exactly as it was discribed in the tutorials. Everything is working fine, except the wifi module.
When the device is in the airplane mode and wlan is activated, there is no problem, but when I turn off the airplane mode and turn it on again after a short time, I get a reboot or the wlan settings screen freezes at "WLAN is activating", when I want to turn on WIFI again.
I tried all available kernels (devil, semaphore,...), tried TeamNyx RC5, tried CM10 and nothing improved this situation!
Flashing the JVU(or another stock Gingerbread) via Odin, I can use the WLAN correctly.
Thanks for your efforts!
EDIT:
I get the same problem on CM10
Using CM7 everything works perfect!
Please: If you got the same problem, answer to this thread!

Same here on Vibrant. CM9 and 10 only.

maybe your ril is just not combatible,
instead of just using the recommended ril try a few others.
also, if you have any power saving programs set to auto switch to 2g when screen is off, could be causing the phone to turn off the radio to switch to 2g / 3g and thats not working because the network is unavailible.
changing your ril orchecking your power settings with any radio manager (like the power manager in CM) you can set it to turn off / on 3g when wifi is on / off and so forth.
could be some of these settings messing with it, and becasue the ril / bb is not working correctly its just bomming out and staying on flight mode because its lost the signal.
so either try a fresh full wipe install install (do a nandroid for backup testing)
check your problem with a fresh install. change rils if you experience the problem (use any of the rils with the same number (.eg. 0725 rils or whatever) check the discription on getril as it pops up what it is and where it came from in a pop up as you select them.
keep matching til you find something that works, (try about 4 - 6)
if all of the above dont work you may try a BB change. but take extreme care*
i dont like changing basebands unless i have to =/
Try 218 ril.
i had that problem while using temaseks kang with proper RIL (phone would lose signal and wouldn't reconnect to network, and trying to reboot with a airplane mode on/off would just make the phone stuck in airplane, even after reboot). the thing that i noticed is that airplane mode would get stuck if activated from power menu, wireless networks menu .. but solved the problem adding the Airplane mode to the notification bar power widgets (icons in notification bar) and airplane mode would then get deactivated normally. that was the only way i got to deactivate airplane mode running temaseks kang.
hmm, still trouble. Flight mode is randomly enabled, and only reboot can change this...
I have used [CM7][UNOFFICIAL][NOV10] temasek's ROM for more than one year with default kernel,
I now have updated all my phone
Only change i have now is that i use kernel: 2.6.32.59 symbi0sis-v1.3.1-UHC [email protected]#1
Thanks to temasek for a really nice ROM!
But, could this kernel make this type of flight mode trouble?
Should i use another kernel?
Or is there a other solutions?
In app GetRIL i get message that RIL/baseband dosnt match.
Seems that i have RL 0218 /V10b Erope) but i should have 0725 (V10d, europe) Any comments?
Thanks
I fixed this problem by disabling automatic time in settings. I then installed Clocksync to set the proper time. Dont know why this worked, but it just did, so give it a try and reboot.

if it helps,
i have a same problem with cm7 and galaxy3.
still trying to determine what triggers it.
i'm not willing to give up on cm7. it's a great rom

[Q] WIFI issue!! AOKP milestone #5 T-Mobile USA TAB

Hi I've been trying to find out the problem for past 2 hours and flashed again many times and i cant seem to find the problem here.
the problem is that after a clean install of this rom AOKP milestone #5, i connect to my wifi 2.4GHz. 5GHz doenst seems to work.
it doesnt even show. now the problem is that when i reboot once than the tab cant turn the wifi back on.. so i cannot connect to the wifi.
i get black toggle not gray like the other toggle and i go into the setting menu and the tab tries to turn on the wifi but i can't.
it just says "turning wifi on" and nothing. so i flashed again and same problem occur. i dont know the problem.
so i am trying to restore the overcome 4.1 nandroid backup but it doenst work from the new CWR (MTD).
how can i flash the recovery (non MTD) that i used to have with overcome rom.
if i cant do i have to restock all the way again so i can restore to overcome nandroid backup that ive made?
if i have to restock, what do i have to do from AOKP Milestone #5 ROM (MTD)?
Thanks in Advance
Dan
You restock the same way as in overcome.
Fire up Odin and flash with repartition.
Then you can flash overcome kernel and boot to cwm recovery and restore.
Don't know about you, but my overcome Android restore always have FC after reboot to the point of unusable.
I usually have to wipe all and restore from titanium backup instead.

Never quite seen such in aokp.
Do you have MAC address filtering in your wifi router ?
With aokp the Mac changed but I thought only once, not every reboot.

I read this on a thread.
Guy had mobile data switched on, and whenever he rebooted, wifi wouldn't connect.
Guy switched mobile data off, rebooted, wifi started working, then turned on data.
Try and let us know.

Sorry for reviving this thread, but your comment has helped me out. I have AOKP M1 on my i605 and wifi has been a pain. Turning mobile data off, wifi on, and mobile data back on solves the problem. Thank you!

[Q] [CM10] 2G/3G toggle switch not working

Hi guys, I have a problem with the 2G/3G toggle in the notification bar. It doesn't seem to work properly. When I want to switch to 2G, it immediately switches back to 3G.
A reboot does not help.
Does anyone else have this problem? Is there a solution?
I just want to have a quick way to switch between 2G and 3G. It worked fine in CM9.
i9000
CM10 stable
Stock kernel
Toggle settings is set to 2G/2G+3G
Am I really the only one having this problem?
I find that hard to believe, having only stock kernel and not having changed anything in the developer settings.
Can no one reproduce the bug?

You're not alone.
I also don't work. I tried lots of modem (jvt, jvu, jw4) same results. :crying:
And cm9 works fine !
I can confirm that. But I find it quite weird that a reboot doesn't help. Oo For me it works a couple of times and after that it stops working and I have to reboot.

Same Problem here...my phone (SGS I9000) doesn't seem to work on 2G anymore since yesterday update. If I switch to 3G it works. there seems to be some problem on 2G networking??
Welp, I tried using Semaphore 2.5.0. Didn't work, the problem's still there and unchanged.
Any ideas?
Same problem here. Sometimes reboot helps, sometimes not. I tried with stock and Sema 2.6 kernel and with stock and jw1 modem. Neither of them are working correctly. I'm using a nightly.
+1 on stable cm10
with latest HellyBean the same problem. sometimes the toggle work, sometimes not.
edit: after wipe cache again, it works. a bit slow... but it works!

WiFi activation loop

Hello everyone,
I flashed CM 10.1.2 with build-date 2013 Jul 11 and I can't activate my WiFi anymore.
Bluetooth is ok, but I can't disable NFC - same as WiFi.
I push the button and it's "working" to activate wifi or deactivate nfc - but nothing happens. [edit: nfc working after reboot]
I've got not many ideas what I can do. Everything is working fine with the stock rom v.20a EUR_Open.
Has got someone an idea what I can try?
I did every step on it's own to have a look on which point the problem appears - after installing cm 10.1.2 with cwm recovery.
Bootloader is unlocked.
I'm looking forward to your suggestions and please accept my apologies for my bad english.
Kind Regards
FChaos
For nfc, just restart once, that will fix it
Hey,
im having the same issue with wifi.
When i try to activate the switch gets stuck in grey but it does not activate.
I have it since I installed CM 10.1.2 stable. Before everything worked just fine.
Any solutions for this problem?
Greetz
Wipe cache & dalvik cache
Fix permissions
Reboot
If that doesn't work then full wipe and reflash.
Note: WEP encryption will not work with CM v10.x so make sure you are using WPA on your wireless networks.
I already tried everything you mentioned, but nothing works for me.
WEP is not the problem, because I can't even get to the point to select my router. Also I'm using WPA2 at home.

I presume the CM build you refer to is a nightly? Try a different one or CM stable - nightlies are a beta software and may have random bugs.
The problem occurs since I installed the CM 10.1.2 stable.
After that I also tried some of the new CM 10.2 nightlies, but the problem still exists.
Any other ideas?
Edit:
When I install Android 4.1.2 Stock everything works just fine, but the moment I install CM wifi does not work anymore.

[Q] HP touchpad wifi not turn on Cm11

Hi all,
I recently flashed the cm-11-20140913-SNAPSHOT-jcsullins-tenderloin on my HP TP first time after WEBOS and love to have android on my TP. Although it was working perfectly regarding all aspects, but two days back wifi stops working suddenly and it doesn't turn on. When i slide the bar of wifi from OFF - ON it didn't move and the screen says WIFI TURNING ON and remains. After that i completely wiped all the data and flashed another version of CM11, it did work for some minutes and again the same problem with wifi. I then tried (After Wipping again) the old CM10.1 version with supported files but again it doesn't on from the start. One thing i want to mention that when i change the CM11 version it stops working after couple of minutes and then i shut down and check in the morning it was again working and then again stop after rebooting. I also tried to control it from WIFI Apps i.e. wifi control, wifi manager when it works for some minutes but the apps also failed to TURN ON THE WIFI when it fails from the system.
I also try to search this topic but i didnt find any which worked for me.
Any help regarding this issue would be highly appreciated.
Regards
No any Response:S
First of all, how did you "flash" the ROM? Are you using tptoolbox?
Also, there are several newer versions of jcsullins ROM available to install.
What gapps did you use?
Please provide more information on your part so folks are able to help you.

I have this same issue, wifi works fine on lollipop, but not on cm11, i originally used tp toolbox to remove webos, resize partitions and flash lollipop. I tried going to cm11 for full functionality and wifi would not work, i tried 3 different cm11 based roms and none worked, i went back to lollipop and wifi worked right away.
