Just recently, in the past week or two, my router has been kicking me off aim after a few minutes. I know its my router because when I'm hardwired directly to my cable box it doesn't do anything...and on top of that, I know its not my wireless card because I can still surf the net totally fine. I even connect to my next door neighbor's router and AIM doesn't have a problem when I use their router.

Anything I can do? Its doing it to my roommates too. Does it have something to do with a stupid firewall? I had this router last year and this never happened once so I'm kind of confused why its doing it now...
