Router was working wirelessly before I just moved, and even after I got settled in my new place. All of the sudden I cannot connect wirelessly from my MacBook Pro. Believe my operating system is Snow Leopard. Modem is fine, has been checked and reset by Comcast. I can hardwire from the modem to the computer and get online. I can hardwire from the router to the computer and get online, so the router does work. I cannot get wireless connectivity through Airport to my network. Linksys online support won't help me for free through online chat because my warranty is up (router is probably two years old). Can anyone help me fix this?!?
