....and then the network disappears from the list for about 5 minutes. After a hardware test, nothing showed up, this leads me to believe there could be a problem with the router. But I can access the router (when I can connect) fine and alter settings. (And as only I know the password for admin, no settings could have been changed). Will this be my MacBook or simply just the router (Linksys WRT54GS)? The other PC on the network is connected to the router through a cable and has no problems.
