thank's for fast reply but i try it on 3 routers tp-link - cisco - d-link but not working

You can do Factory Reset from Main menu (Back Up/Restorw) but I don't think it'll help. After all, only flashing new rom left. Try, if not.... Send it back to Samsung I'm not sure

[Q] CM on ace help!?

Every time i am flashing a version of cyanogenmod my wifi doesn't work on my router at home but on school it does work On stock rom or stockrom based roms is my wifi at home working. Flashing another modem i already tried
Thanks

Do you have a password on your home Wi-Fi? If you do, start the Wi-Fi from settings->wireless & networks -> Wi-Fi settings, otherwise you don't get prompted for a password.
You should try to flash different region's modems..

I have a password and i have insert it -.- A diferent modem doesn't work i have already tested that. Thats the weird. On school my wifi does work. At home not. Stock rom works at school and at home.
Did you test other devices on your home wi-fi? You might need to look into the router status.

Try to set static ip in wifi configuration if you know how to do and what to write.

Tried everything and I still have the problem. Really nothing seems to work.
I'm reading about resetting my router, full wipe, your tip,...
Is there anything else left?
You can try reflash the latest firmware using odin.

Have you tried
Settings/more settings/mobile data/automatic connections, make sure the box is not checked.

If you are in the UK, update your modem to LH1 , I had this and lh1 was released to address this problem
Still haven't found a solution. Back to stock rom now and back to samsung for repair i guess.
I have the same issue (stock, unrooted, factory unlocked) and I have the LG8 modem. Only started after the latest OTA update which took me to LG8. It's not my router because I can make a 20 minute Skype call on my wife's iPhone and on this phone it cuts out after a minute or so, every time. Even as I'm typing this, I see the message on my screen telling me I'm reconnecting to my router every couple of minutes. Very frustrating.

Did WORK with ARHD 3.0!!! THX Mine problem solved!!!
I'm still trying to fix mine.
When i'm near my router/modem it can connect and download at slow speed. When I move away I lose connection.
And after a reboot or just when trying to connect from a further distance I get: authentication error occurred.
Even with my open network.
I think it started happening after the installation from the first OTA JB.
Maybe installing this one again could help?

For your case, did you try wipe/factory reset?

Prior to enabling wifi tether you must enable mobile data first.Your device will be used as access point so it will disconnect from your modem/router and must have an internet connection to share.So turn mobile data on!!

I'm not daft, it was working. When I turn it on it starts it up then about 3 seconds a box pops up saying a error accrued during tethering. I've tried refreshing my stock Rom and a custom same problem, I don't know if its a problem with my build? It's not a hardware problem I dont think

Mobile data and Wi Fi aren't working

Mobile data connects but won't load anything...works on other phone.
And WiFi disconnects instantly after connecting or stays in obtaining IP address loop. It was working fine few hours ago. Now I tried to reset router, phone but still its not working. All other phones and PC are working fine with WiFi.

For mobile data have you added your service providers details in APN?
Wifi, IP address correct?
If they are try reflashing Firmware via odin.

Must Try Reflashing The Kernel. The Kernel files may have corrupted
