I've installed Jelly Bean custom ROM for Samsung Galaxy S3; then when I tried to connect to the wifi, my phone shows that the signal is very strong. After a minute of connecting, it shows a message "Network disabled, poor connection". The wifi setting was saved, but still can't connect to the internet. Then I flash it back to its original ICS ROM, and it easily connect to the wifi.
There is 2 different JB Custom ROM that I tried, and both of them are having the same issue. What should I do?
I've search this problem and found some answers, but those answers are not working for me.. Please help..
Wait for Samsung to release JB instead of using Beta test roms .

Which roms have you tried? I have the same problem but it's only on the latest leak (DLH6). Wi-Fi on roms based on DLH4 works fine for me.

Which modem did you switch too? Worth a try.
Its because of WIFI encryption, remove the password and try.
It's a bug in the leaked builds, they're BETA so you can't blame anyone but yourself.
it seems some people also had success after changing from wpa2 key to wpa key on there router.
I've the same problem.
I used to use Resurrection Remix JB 3.0.6.1 and everything worked fine. Then I flashed another CriskeloRom v13 (both are JB), and WIFI worked fine as well.
The problem was: when I flashed back to RR Rom, I couldn't connect any of the WIFI access points (actually, I tried 2) though the signal is very strong. I tried different settings and I also reset the APs and it didn't work at all. I also tried different modems and it didn't work either. Then I tried to re-flash both ROMs and found something may help:
1. flash RR: pass (before this the ROM was an unknown 4.0.3 version came together with the new phone)
2. flash CrisKelo: pass
3. flash RR: fail
4. flash RR with different modems: fail
5. flash RR ICS: fail
6. flash RR: fail
7. flash CrisKelo: pass
8. flash RR: fail
Anyone can give me some hint? What I need is the RR JB ROM with WIFI connections!
Sorry I can't paste external links because of the privilege, and both ROMs can be found at galaxys3.roms-db.com.
Best regards,
Same problem here. Running CheckROM v5.5. Have tried 2 different kernels (Perseus and Siyah). Hopefully the XXDLIH release will fix it....
hey guys,
i found a lot of theats for this topic, but no one can help me.
wi-fi will work and i find all wireless networks in my neighborhood, but if i connect, the signal strength decrease to 1 - 5%.
then android reconnect.
the signal strengh will great until i try to connect.
one solution i found descriped to install the stock rom and then update to cm. but if i try this i get the bootlook. i must factory reset the device. then all data will lost. and i get the same problem.
does anyone know what happens?
i tried 3 AOSP roms, cm9, cm10 and AOKP rom.
all 3 with android ui has the same problem. only the stock and samsung based roms works.
at the moment i use Android Revolution HD .
but i don´t like the samsung ui

Hi, Just follow the instruction in op and you wont have a problem. Not to lose anything just backup them! Simple!

You have to ODIN flash 4.0.4 stock rom before flashing CM10 to get rid of wi-fi issues. Thats all I know about that.
Did you lose your way to the cm10 discussion thread?

I have a problem with wifi. I have to reconnect wifi every morning. It looks like it's connected, but internet doesn't work until I turn off and turn on wifi. I need to do the same thing when i came home. Wifi connect but internet doesn't work.This is happening only on stock 4.1.2 roms. I tried to copy /etc/wifi folder from this thread http://forum.xda-developers.com/showthread.php?t=2114095

Same with me. I also tried the /etc/wifi files from LSJ (even made a CWM-flashable ZIP with these), but that didn't help. Flashing different kernels, or forgetting/reconnecting the Wifi connection didn't help either.
I have the same problem also. It's very frustrating bug that you need constatly turn off and on wifi to get data connection back. Looks like there is good wifi signal but still not data connection before restart.

the same for me very frustring !!!! xwlsd (xwls8 > same)
Hi to all
I really don't know why, but last two mornings wifi worked without turning off and on. I have xwlse rom with philz xwlse kernel 4.64 on my phone.
First i installed dorimax kernel 7.48, but phone was very unstable. So i installed xwlse rom and philz kernel with mobile odin.

xwlsd and phil'z kernel 4.63 fixed > bug wifi but not all time it's works well for 2, 3 days and the day after: bug : turn off, turn on and it's ok
Hi. I never had this problem. I'm on 4.1.2 xwlsd. What i did was a clean install of my system. This instructions are for the international version GT-I9100.
1. Download Odin3 v1.87.
2. Get the official firmware form sammobile.com.
3. Open Odin3 and put your phone in download mode. Connect it to the PC and make sure the yellow square appears.
4. I used a pit file to reparation but don't recommend you try it. You can hard brick your phone.
5. Thick auto reboot, F. Reset time, phone EFS clear, phone bootloader update.
6. Press on PDA and browse the firmware you downloaded. Be sure to extract it first if it's a .zip file. You should see a .tar file.
Now you have a clean install of original firmware. Good luck.

So you are saying this problem is kernel related... Maybe is possible our problem is becaused of phil'z kernel? I have to try to keep the stock kernel, and monitoring the situation...
Inviato dal mio GT-I9100 con Tapatalk 2
i don't think this is the kernel is fault because phil'z kernel is stock kernel.
Same problem here with stock rom, no battery saver apps, and battery saving not active in the settings.
Upgraded to JB with Kies, factory reset afterwards.
R: Wifi problem on stock 4.1.2
Ehy guys, what kind of wifi module is installed on your phone? Murata or Samsung? Mine is Murata, and maybe or problem is manufacturer related... Do you think is it possible?

You have to go here: http://hwaddress.com/ and you have to write in the box the first 3 couples of number/letters of your S2 MAC address(xx:xx:xx). You can find it in wifi advanced settings. In few seconds you will know what is your wifi module manufacturer... Let me know you results...

Samsung Electro Mechanics for me
Murata Manufacturing for me .
R: Wifi problem on stock 4.1.2
Ok... We can exclude the wifi issue is manufacturer related... We have to think if there is something more we can try to fix this crazy problem.
Inviato dal mio GT-I9100 con Tapatalk 2
Samsung Electro Mechanics for me too. It's not a HW issue, because under stock ICS, or under AOSP/CM/AOKP JB the wifi works fine. The issue exists only with the recent stock JB roms, and those based on them (NeatROM, Omega, WanamLite, etc). It's also not caused by the kernel, because I've tried stock-based kernels and upstream-based kernels (Dorimanx, Siyah) and the issue persisted.
Has anyone tried flashing older baseband/modems? They shouldn't be related to the wifi in theory, but who knows...
R: Wifi problem on stock 4.1.2
At this point I'm thinking the problem is caused from one of the apps we installed on our phone, maybe for some kind of incompatibility with JellyBean... As I said some posts ago, next week I will try to flash Android 4.1.2(XWLSD), without root, and I will use the phone with none of my apps installed... I will give you some news about this proof in the next days...

Hi guys,
I flashed CM10.1 and carbon and infamous and on all those 4.2.2 roms i have a problem.
That problem is that none of those roms can connect to my router.
If i reflash the stock rom then it works perfectly.
If i reflash cm10.1 then it does not work anymore but it can connect fine to other routers.
Is this a problem with my router or with cm10.1 ?
i dont think the router is the problem as i completely resetted it each time i reflashed and on stock rom it works perfectly.
Any help is welcome.
Grts Dave
Also i always did factory reset and wipe cache and all.
I just now reinstalled cm10.1 and again no connection to the wifi.
I get full signal and it shows the security and strenght of the signal and all just when i push connect it does not want to do anything.
The router is a wndr3700 with dual ssid 2.4 and 5ghz
Tried now giving the tablet a static ip in the router but also that does not work.
Im getting crazy here cause on stock ics rom all is working
By any chance did you flash another kernel after flashing those ROMs? Because flashing wrong kernel can sometimes lead to those error. I personally experienced it myself.

Nope did not flash any kernel after the rom flashing.
Came always from stock to either cm10.1 or carbon or infamous roms.
Did not flash any other kernel after that.
I tried CM10.1 again now but this time with the A1 kernel 1.9
This combo also does not let me connect to my wifi.
I just cannot figure it out why the stock firmware can connect perfectly but any custom 4.2.2 rom cannot.
Im using ARHD 40 with boeffler kernel and Ive noticed my 5ghz wifi channel has gone. Ive tried with the stock kernel and its the same. Any ideas how I can get it back?
Wipe and flash a full stock rom, same answer as any other fault.
If it works with stock then you broke something in your firmware, if it doesn't then you have a hardware fault.
