[Q] 3G stop working..

HI
I have a strange problem with my Arc s (the problem suddenly started this week).
when i turn it on the 3G works but after 2 minutes it show the H sign of 3G but no internet and also no calls. when i disable data i can call.
so i figure the 3G is working bad.. and cause to network in the device to fail..
its not rom problem.. i tried 5 different roms and the same (and the device worked great with he first rom before).
the store don't want to fix it because it say because i installed rom the warranty is expired..
can someone please guide me how to fix it ? can i order the 3g component and fix it? thank you

[Q] MIUI 3G problem

I`m using MIUI rom from here on my phone. There is often some unknown problem with 3G/Edge connectivity when i disconnect it from Wifi. Nothing can help even changing between 2G/3G modes to force Cell reconnect. The only solution that can help is to reboot the phone, but WHY? If there is some patch/fix/anything to get rid of this problem?
Thanks a lot.

Please post in the correct section.

Rom SMS receiving on WIFI issue???? HELP

Please help guys.
I installed perfectly the V10 Google edition "feel the experience" ROM with 4.2.2.
My APN settings seem to be correct but whenever I'm connected to WiFi I can't receive any messages until I turn it off.
I know there's no WiFi calling, I'm just saying in general if you're connected to WiFi you won't receive any SMS until you get back on 4G or LTE.
I'm trying to figure out if changing the channel mode of the mobile Internet will help but idk how to get on there using the dialer.
Last thing, I would have replied to the actual ROM post but it doesn't let me reply due to my low amount of posts as a new user.

Wifi problems

Hey guys,
i have a weird problem with Wifi on my phone (LG Optimus G). Since Android 4.4.2 and now also Cyanogenmod 12 i got problems with my wifi. It shows me that my wifi is connected, but i dont have any connection to Internet or Network. I have first to switch wifi off and then again on to make it work again. This is happening 5-6 times each day.
With Android 4.1.2 i dont have this problems, wifi is working perfectly. Would it be possible to import the wifi driver from 4.1.2 ?
I used for sometime the app wifi reconnect to not switch the wifi alle the time manually on and off, but this is also not a solution.
I hope someone can help me.
regards

Noone a Idea ? What could i do alone ? Where can i check the wifi logs ? Could i take the driver from 4.1.2 ?

ROM With Working Wifi Calling?

Hey everyone, so looking for a rom that is newer Android 5 or 6 that can still take advantage of Tmobiles Wifi calling.
After the last update my cells been randomly rebooting and incoming callers cant always hear me so im ready for a change.
Tips for those that dont like wifi calling:
Incoming and outgoing calls and texts work flawless on wifi calling.
It does need to connect on the tmobile server (4G) after a reboot or it wont work.
You need to have a better signal connection with your router/modem more than say a faster connection.
It will work the same on Wireless N @72 as AC @433.
Last and my favorite you can put your cell in Airplane mode then turn Wifi on this will save much
battery life as your cell doesnt ping tmobile on the cellular network.
Thanks everyone hope someone knows a newer rom they can point me towards Thanks!
