Hello,

Did you find any solution for this ?

I'm in the same "club" and I even attached a serial console to the router..but issueing nvram erase from that ..makes the console freeze => requires reboot
also I see this in the boot seq:
Device eth0: hwaddr 00-1E-8C-72-2E-CE, ipaddr 192.168.1.1, mask 255.255.255.0
gateway not set, nameserver not set
Null Rescue Flag.
Reading :: TFTP Server.
Failed.: Timeout occured
Loader:raw Filesys:raw Dev:flash0.os File: Optionsnull)
Loading: . 0 bytes read
Failed.
Could not load flash0.os:: Error

Of course..IP is not pingable via any method like:
- after boot
- hard-reset
- 30/30/30 method
- keeping ping on, then power off, ping on, power on..etc
I don't even get by using a Linux, any arp reply from the router..seems like it's as solid as a wall.
