ya i was thinking dns, but it really throws me in a loop, becuase it goes off and on, and as of right now My mac which is on the wireless LANworks fine, but my 2 windows boxes and my linux box has nothing. (Yes i restarted the router, and yes i restarted my cable modem) Should i call the moron at comcast? ussually anytime i call them with any problems other than the obvious they have no clue what to do, and never send me to a higher tech support.
