Ok here's the way it went let me say I had the newest version of dd-wrt but I didn't like it.
1st I did A 30-30-30 reset.
2nd I telnet to the firmware and eraced, rebooted, Then waited a couple of minutes to reset. the names were root / admin
3rd I used a program called TFTP2.exe to flash the original firmware, Did anouther reset and volia I'm back to the original settings!
OH and the telnet password is root / admin
you happen to know which CFE version you have? 1.3 or 1.5?
I donn't think it would matter would it?
