Seems to me that that router did not have it's config saved. If you've got a copy of the config you could paste it in.

 

by: wiscomPosted on 2009-08-18 at 10:03:47ID: 25125265

Hi,

Or check the config register. Do a "show version" look at the last line. Must be set on 0x2102

Check also NVRAM with the command: dir nvram: [enter] , please send the output of this.

THANKS! I did what you said "check the config register. Do a "show version" look at the last line. Must be set on 0x2102" and it wasn't set to 0x2102, it was set to 0x2142, I made the change, cycled the router and BAM, back in business... I wonder what would've made it just go to that state after working for I don't know how long...
