Just bought a new WRT54GS: Hardware profile: Vendor:LINKSYS ModelName:WRT54GS Firmware Version:v3.37.6 , Dec 29 2004 #:000 Boot Version:v3.4.2 CodePattern:W54S Country:US RF Status:disabled RF Firmware Version:v3.37.6 RF Domain:US (channel 1~11) RF Channel:8 RF SSID:MWNet -----Dynamic Information RF Mac Address:00:12:17:C9:06:0C LAN Mac Address:00:12:17:C9:06:0A WAN Mac Address:00:12:17:C9:06:0B Hardware Version:2.0 I use at as â€œGatewayâ€ â€“ It connected to Cable modem. When I first install it I connected all my computers to Lan ports, I didnâ€™t have any wireless computers, and Wireless mode was â€“ Disabled. Now I need to turn it on But as soon I turn Wireless mode from â€œDisabledâ€ to â€œMixedâ€ it loosing connection with Cable modem. All internal connection are fine. I can connect my wireless laptop, all my wired computers can ping each other, but there is no external connection. To restore connection with cable modem I have to Disable wireless and click â€œDHCP Renewâ€. Does anybody ever have this kind of problem? I just in case upgrade my WRT54GS to the latest firmware from Linksys, but it have not change anything. Now my question is: Is it something known and could be fixed by upgrade/downgrade firmware or set some settings? Or should I return this device and ask for another one?
