Default Low internet connection- switches to roaming mode

Hello,

Running ARHD 33.1 / stock kernel.

Problem: When my internet connection (not the signal strength bar) is getting low it tells me I am in roaming mode. For example: I'm in a room with very thick walls, it sometimes displays the 'E' connection and few seconds after I'm in roaming mode.

It happened for the first time when I flashed a wrong kernel (sense 4, but I was running sense 5). I was stuck on bootlogo, flashed stock kernel again and my phone was working, except this internet connection thingie... I was doing a full wipe, fastboot erase cache etc, reflashed ROM.. nothing helps.

I hope someone can assist me to solve this issue.
