I have a very strange Problem.

I can't access my router via LAN.
WAN is not working !
Is only accessible via WiFi but again no WAN is up.
On the log files i see that USB is failled with error 79 and all NAT and WAN are down.

I can do FW Upgrade - Change CFG - can access it via telenet, but only via WiFi.
Lan don't answering on Ping and olny switching (Switch Box) is working.

What can i do now ? Is HW fail and i have to forget it ? or some trick can revive it ?

Here is the log file....

Try reverting to factory defaults.
 
Done this several times, tried all available fw versions also,
Nothing helps. Is strange but the router is still semi-bricked.

Rescue mode is not working also.:confused:

This situation makes my crazy...
All my services are down including streaming to TV.

Now the Router is back in Service by Own, without do anything.
But i Think i found the problem.

Code: 
00:07 kernel: Physically mapped flash: CFI does not contain boot bank location. Assuming top.

It can't finf the CFI location for mapping and the ROUTER hangs to load Services.

The log now is this.....

etc .....

This is normal and the Router is fine,,,,,

Is the Second time i have the same problem and i really don't know what causing all this mess....

Is the 64K cfe mod the source of my problems ?
 
Hi,
Have you ever cleared NVRAM or performed 30-30-30 rest with your router?
