I currently am trying to program the config for a 1720 router however i cannot get the config to stick. I boot up to the command prompt put in all the configurations use the "write mem" command and then hard reset the router but when it boots back up I get the initial system configuation dialog.
I have tried booting to the rommon prompt and typing "confreg" and following the prompts keeping all options set to no except for this setting
"enable "ignore system config info"? y/n [n]: Y"
Is set to yes. but when i get to the end of the config it just loops and starts over with
"you wish to change the configuration? y/n [n]: Y"
If i choose yes it loops if I choose no it goes back to the rommon prompt. Am i doing something wrong?

Hi,
reconfigure the router and use as first command:
-enable
-conf t
- config-register 0x2102
- do wr
-do reload
You should have solved your problem and then you can finish configuration and write to startup-config.
Regards.

Check your config register using the command "sh version". The correct setting should be 0x2102.

Configuration register is 0x142

Input from your commands.
Router>en
Router#conf t
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#config-register 0x2102
Router(config)#do wr
^
% Invalid input detected at '^' marker.
Router(config)#do reload
^
% Invalid input detected at '^' marker.
Router(config)#
After that I input my base settings for the router reset the router and it seems that my settings have stuck. Thank you so much for your help!!!
