What can I do... about confreg-register

Soon Kwan Kwon

Hello guys.

I have two Routers (2801, 2811)

 

I changed the confreg-register from 0x2102  to 0x2132 by my mistake.

But it is not working properly.

When I connected to the routers with PC, in the PuTTY, its font was broken down.

 

So, I searched it and then I found that the answer was to be setting the console speed more than 9600.

I did following that steps.

 

However, I recognized another problem was present...

After I configured register 0x2102, but It was changed 0x2122... 

Continuously I changed register, but continuously remained 0x2122. 

The point is .. Why did it change continuously 0x2122??? 

Please teach me what can I do to fix it!

Regards,

Eject the CF from the router(s).  Reboot the router into ROMmon.  Change the config-registry value to the correct ones from ROMmon:  config-register 0x2102.

 

Once done, insert the CF and reboot the router once more.
