I have a Linksys router BEFW11s4 and that is hooked up with another Linksys (for Vonage) and they are hooked up to a PC. I always connect with my 12" PB G4 via airport and NEVER have had a problem. Then, I went and messed with the router and had to reset to factory default. I changed the SSID and had it not broadcast - I can't set any WEP or WPA because they are different on the mac and the router. My mac now has a signal with the router, and after restarting the router,the pc, the mac and running network diagnostics, I CAN NOT get the mac to connect to the internet. Any ideas? I'm getting very frustrated Also, I'm getting the internet on the pc.
