i recently got onto wind and went with the LG optimus 2x. for the past 4 weeks, the wifi has been working fine but a couple days ago it stopped working. it manages to obtain the ip address and everything but when i try to go on youtube or facebook, i get a message saying "there is a problem with your network, touch to retry." the signal strength is strong,the wifi icon is still there,and at settings, it says i am connected to my router(d-link) so i dont know what the problem is.i've tried factory reseting my phone and turning it on and off but the wifi still doesnt work. someone please help!!!!!!!!!
