When you are at ROMMON, type "confreg 0x2142". This will disable the

password requirement. Then boot the router. You will come to "Router>" mode.

Go to enable mode (type "enable") and then copy the stored configuration to

a text file (issue "show start" command and copy all the output to a text

editor) and remove the password (if you have aaa configuration, then issue

"no aaa new-model" command). Then copy rest of the configurations back to

the router. Then, go to configuration mode and type "config-reg 0x2102",

exit out of the config mode and save the configuration (write mem). The

procedure is also listed in the link below.


Hope this helps.

If NT's post (+5) above doesn't work for you, then the next one carries a disclaimer.

Using this process, the CONFIG of your router will be erased and the router will be reset back to factory default.

At the back of your 877W router is a "Reset" button.  Turn the router off, hold down the Reset button and turn on the router.  Wait for about 10 seconds before releasing it.
