3.Wifi only connects on Resurrection Remix ROM but not on Stock ICs which is my secondary Rom

Flash another Kernel or at least the same one again!
Wifi probs are most time related to kernel.

[Q] Wi-Fi doesn't work in all custom roms! Help me!

So this is the problem. Wifi works ok on my original 2.1 firmware. But it doesn't work on custom roms. Why is that? How can I fix it? Please help me someone/
Hi there
Some additional questions:
1) which custom roms have You tried ?
2) what do You mean by "doesn't work".
- Can it turn WIFI on ?
- Can it discover network?
- Can it connect to the network?
Which part is the problem.
Cheers

1. Couple of elenix , fusion rom , and others,cant remember their names.
2.Yes WiFi turns on ,discovers my network,says that it remembered it,but at the last step it says on the network Disconected,and on Wi-Fi disconected,and wifi begins to connect to it again,and it can happen like that forever.
I would think it's router related.
Have You tried with other wireless networks ?

wifi stoped working at all!! check rom v4

I installed check rom revoHD v4 and wifi just stopped working. When i activate it, it says its activating, it turns on and a few seconds lates it turnos off. It never gets a mac adress.
I tried changin kernels (siyah 2.51), and modems with no luck. Anyone has an idea how to fix it?
Thanks
(everything else seems to be working fine, bluethooth gps etc)

What kind of security is your wifi modem is having? is it wps smthng lk that? Did you tried with different wifi hotspots?
it doesnt have any security, i disable it
The thing is that it doesn even recognize that there is a wifi signal, it just turn off automatically before without detecting any wifi signal, i tried at work and the same thing happened
(sorry if i misspelled a lot of words jejeje)
try to flash another ROM and see if it works...
Sent from my GT-I9100 using XDA premium app
i restored the backup i made with cwm and everything works fine now (touch x-power rom), and if i reinstall check rom the wifi goes out again, it seems it deletes something that leaves me with no wifi mac adress (i searched in about the phone, turning on and of wifi and every time it said not available)
Bizarre...
im getting the same thing, did anyone find a solution?
had this same exact issue.. it is a hardware problem.. so changing rom, kernel or fw wont help you at all... only solution is going to samsung service center.. my problem was solved in 3 days..so many s2 users have this problem..
take a look at these threads...

There are a lot of problems with KK5 and wifi. If you update Busybox it borks it completely. I can't connect to my 5Ghz home wifi but the 2.4 Ghz works fine. I also can't connect to some wifi that uses WEP. All works fine with previous builds. I have seen threads that suggest replacing the wpa_suplicant file from Android 2.3.5 fixes the problem.

CM10.1 wifi keeps disconnecting crazily.

Hi all
I am using latest cm10.1 rc2.

After a while my wifi connection starts to disconnect and reconnect all the time until i disable wifi. Damn it drives me nuts.
I flashed stock rom yesterday no problem with it. Then i flashed cm again an hour ago and problem comes back.
Any solution?
Using an airties modem + airties ap.
Of couse i searched for an hour but couldnt find anything usefull
Solved it by replacing some wifi files from stock rom.

Hmmm, dorimanx and siyah kernel isn't compatible with cm12. cm12.2 doesn't exist yet, maybe it is a kernel related issue. Try apolo kernel 8.0 or gustavo kernel since they are compatible with lollipop.

WiFi issues across rom's

Sooooo. I have a problem with my ls990.
WiFi won't connect to anything. Sometimes it refuses to turn on
Bluetooth, cell service and data service all seem to be working.
There are three main WiFi states that happen.
The occurrence of theses seems to be random and they only change after a reboot.
WiFi stuck turning on
WiFi can see networks but can't connect
After boot, it auto connects then after a few second/minutes then disconnects and resorts to one of the two states above.
I have tried flashing to stock ROM ZV4.
The first time I flashed the ZV4 ROM via LG Flash tool, WiFi worked. However, when I flashed lineage os after, the wifi problem continued
When I flashed the ZV4 ROM a second time, the WiFi issue resumed.
Since WiFi does connect to WiFi networks occasionally after rebooting, this has led me to believe that this is a software issue and not a hardware problem
TL;DR: WiFi doesn't work after stock ROM flash
If anyone has any idea as to what the problem is or how to fix it, it would be greatly appreciated! Thanks in advance. :good:
Bump as I'm having the same issue on my wifes G3
