I've been configuring a Cisco 1811 router and I'm pretty sure I messed it up, so I went to restore the factory defaults. I followed this set of instructions (fronm Cisco's site):
This method uses the config-register 0x2102 command in global configuration mode.
Check the configuration register on the router by issuing the show version command.
The configuration register setting is displayed in the last line of the show version command output and should be set to 0x2102. If this is not the case, enter the config-register 0x2102 command once in global configuration mode.
If the show version command is issued again, the same line in the command output will have '(will be 0x2102 at next reload)' appended to the current register setting.
Erase the current start-up configuration on the router with the write erase command.
Reload the router with the reload command. When prompted to save the configuration, DO NOT save.
System configuration has been modified. Save? [yes/no]: n
Proceed with reload? [confirm]
Once the router reloads, the System Configuration Dialog appears.
--- System Configuration Dialog ---
Would you like to enter the initial configuration dialog? [yes/no]:
The router is now reset to the original factory defaults.
I got to the line that said " Would you like to enter the initial configuration dialog? [yes/no]:" and I quit otu of the hyperteminal as I wanted to do the configuration via the web interface (as I don't really understand the command line yet). The problem is the router isn't giving any ip addresses. I tried the default address (10.10.10.1) but that didn't work. If I do an ipconfig on the computer attached to the router it gets an invalid ip address (18.104.22.168) even though the computer is plugged into the router via cat 5 cable.. My question is how can I reset the router so that I can access the web portal (10.10.10.1)?
