Lag,internet,EA online, and more lag

[0x0Glitch0x0]

ok so here is my problem one day i got on BattleField3 and i could not connect to EA online at all. It would launch the game and then it would instantly close the game and say BattleField3 has stopped working. Then in the bottom left Corner in the box that would say what sever im on ect. would say that i was disconnected from EA online . but then the games it would let me into to play my ping would go from 64 to the thousands in seconds. So i thought i would get on my xbox and play battlefield 3 there and it worked fine and my xbox and PC use wirless internet but PC battlefield just refuses to work with me. Please help this has been going on for months and i want to get back into PC battlefield.
