SMC Barricade WAN problems

[Goi]

Hi guys...
I had my 8 port Barricade working perfectly with my cable modem service, until just earlier today when it just stopped working. The router lights are still on, correctly(WAN, LAN, FDX, etc), and so are my cable modem lights. Connecting my PC to the cable modem directly works, which is why I suspect, if not confirm, that its my router that's the problem. The LAN still functions, but I just can't access my cable modem connection.
I went to the router web setup page, and all the numbers are 0, with the "remaining lease time" in reconfiguring mode for an eternity, and the gateway unreachable
I'm using the DHCP server(no fixed IP address for each NIC), and nothing has changed. What could make it just stop working? If its a faulty router, shouldn't the indicator lights indicate that its not working anymore? The WAN light is on, showing a WAN link, and the M1 light is also blinking, showing a functional router. I'm stumped...help!

anyone?

Have you tried turning it off then back on???

 

[Goi]

Yup, tried that, as well as doing that to the cable modem...didn't work though.

If you've flipped it off and on I assume you've also tried to release and renew the IP address as well, right???

You might go back though the Internet Connection setup and make sure nothing amiss in the WAN configuration/setup.

Yeah, I rebooted, and also used winipcfg to release/renew my NIC's IP address, but still no go. Works only if my NIC is directly connected to the cable modem. Nothing in my NIC's TCP/IP config seems amiss. In the first place, everything's setup for auto-detection(DHCP). Could my router be dead? I'm gonna try exchanging for another one...

oh well, i sent the router back for repairs...i'll know if it works in 2 weeks
