not sure if anyone here knows how to fix a wireless internet problem

well like a week ago my laptop stop picking wireless interent connection. I have the router in a different room. Before i could use my laptop anywhere in the house, but i used it mostly in my room. well last week it stopped picking internet connection and it will only pick it up if im like 10 or 12 feet away from the router <.<

whats wrong with it?

and is it possible that the wireless card or whatever in the computer overheat and not work?

its called my life was wrecked and rebuilt by anime and manga

Err...wouldn't the random questions thread be better...?

Erm, basically it's either your router or wireless card. Try moving around the router, it might be something screening the signal. (my guess).
Or borrow another router from someone else. If anything else fails, try resetting the router and setting it back.

If everything else fails again, reset the router and see if it works now. Else, get it to the repairs...
