I know this is not related to runerebels, but I kinda need help :P

My computer is not recognizing the wireless it says that is receiving a signal but not acctually connecting to it, any thoughts b/c it was working fine earlier and I shut down my computer and came back and it no longer is connecting... P.s this was on my written on my iPod :P

Computer, such a vague term these days.  If it is a laptop, make sure the wireless is turned on.   If it is a card to a desktop/tower, rollback to a working driver and get the latest update as the driver may have corrupted.  Dongles could have corrupt drivers, too, but those could also get jimmied out every once and a while.
