I'm having 1841 Router, its configuration is not getting safed. If I reboot the router all my running-config is like default. But when I check my
sh startup all the configuration which I did is displayed. Checked the config-registery too and its 0x2142 changed too 0x2102 still the same problem, when reloading the router all the running config is disappeared.
You need to change the config register.
The routers were left in password recovery mode of 0x2142. Changing it to the proper 0x2102 fixed this mess. I hope this will save others who come across this problem.
Do this: en conf t config-register 0x2102
Hope it helps.
please rate if it helps.
