[SOLVED] Asus Striker II formula usb playing up

I have over the last week noticed my internet dropping out. Then over the last few days my USB Netgear wpn111 just stops working- says it had driver problems. Funny thing is my G19 keyboard goes on the flash sometimes it does this with my internet and my G9x mouse freezes. I then tried a powered usb hub but it still does it. I think that the ZMB is faulty- god dam its only new and its only just started doing this-any ideas.
