I am having trouble with my 877 dsl router where when I boot it up I get to the console
         --- System Configuration Dialog ---

Would you like to enter the initial configuration dialog? [yes/no]

unless I select either yes or no the CD light on front of the router keeps flashing and I can not do anything with the router. If I select no and set some values like hostname and reload the router it dosnt keep any of the saved configurations. My IOS version is c870-advipservicesk9-mz.124-15.T4 dose anyone have anyidea what might be going on
thanks

Hi,

It's either lost its configuration or it's been told to bypass it.

Have a look at the configuration register  with the show version command

At the bottom of the output, it should say:

Configuration register is 0x2102
0

Say "no" to the initial configuration dialog, and at the prompt do a "show version" as mentioned above.  If it says anything other than 0x2102, look for a startup config using "show start".  If the startup config is there, do a "copy start run" to bring that configuration into the running configuration.  Then go into config mode, change the config register to 0x2102, and then save the config ("copy run start").  You MUST bring the startup config over to be the running config, otherwise when you change the config register and save that, you will overwrite the existing startup config with essentially a blank config.

If the config register is set to 0x2102 and there's no startup config, then you're on your own.  Hopefully you have an archived copy someplace.

The console baudrate is set to 115200 instead of 9600, that's why the config register is 0x3922 instead of 0x2102. See http://www.cisco.com/en/US/products/hw/routers/ps133/products_tech_note09186a008022493f.shtml#config-reg-meaning.
