I bought phone with android 4.2.2 os and i cant normaly connect wifi N. In router installed dd-wrt, access point, G/N speed, wpa2. In phone i press connect button and after some time, web browsing, pages stop reloading, but logo shows i am connected. So after that i need in phone turn off , turn on wifi to have ability browse fot ~5 min again..so frustrating. How i can solve that? i dont think touter is problem, because my laptop with wifi working very good.
