Did you setup connection by MAC address on the Router? Check your connection options in the router.
I'm sorry I do believe I had found the issue (N300 Wireless Router - Local Only (Vista)). Vista related (Shocking), apparently wireless, vista, and certain routers don't mix well. I have read possible fixes and had seen updating the network adapter may fix it as well. Have yet to try these but will shortly.
I would take this thread down but I am new and clueless on how to do so. Thanks again though for posting and trying to help me with the issue I've been having.
