[Q] Wifi

view story

http://forum.xda-developers.com – Hello I have a Samsung galaxy s3 i9300. I love working with the phone except for the wifi signal and the celluar signal. I have tried different modem and still no luck. I've read that for solving the wifi problem you have to install a different kernel? What is the best kernel for better wifi signal? If i am in the same room as the modem then i have all the bars full. But when i go to an other room i'm only keeping 1 or 2 bar signal. And for better signal with te celluar i always have to set networkmodus on gsm only otherwise i'm have no reception at all, maybe 1 bar. I use this phone for (HowTos)
