I'm trying to help a friend with a new router. He just purchased a WRT54G V3 router and is running the Linksys 4.00.7 firmware. The router intermittently changes the ssid to Linksys and the wireless security mode to WPA. Other settings such as QoS, password, and DMZ are not affected. When he changes the security mode back to WEP the passphrase and key are still there. Any suggestions?
