Hello guys! I got one big problem.I bought samsung galaxy s4 before 2 days,and I have problem with internet connection on my router.When I connect to the wireless network signal strength is fine and if I try to go to Facebook application,Play store or even browser it just crashes and message pops up "Unfortunately browser has stopped working" same thing is for play store and facebook application. But the one thing is so interested.If I connect to my friend's wireless connection,neighbour's or somewhere everything is working fine. Please answer me and help me,just imagine the feel to have phone like this and can't connect on your network but can on every other. P.S Excuse me for bad english ;/ Regards, Dejan.
