Can't find the network SSID from any of the

Have you inadvertently turned SSID broadcast off? This can be checked by connecting an Ethernet cable to the router, going into Internet Explorer, using 192.168.1.1 as the URL and checking to make sure that SSID broadcast is on in the firmware. I suggest going to www.linksys.com to find more information on how to work with the firmware control panels if you don't know how.
