Just got a belkin n300 and flashed to toastman 1.28.75 rt ext. I am trying to use it with a motorola sb6121 cable modem with comcast service.
Computer connected directly to the modem works fine, the computer obtains an ip address via dhcp, but when I put the router between the modem and the pc the router cannot get a ip address from the modem (also set to obtain an address by dhcp) Just seems to be stuck on renewing.
I have tried different cable and power cycling each component.
Bringing the router to my office it obtains a wan IP address from another tomato router just fine.
edit: reading up on the issue it looks like I need to have the modem unplugged for a longer time or clone my laptop mac address to the router. won't be able to try it out until this evening.
