  • Can't save config on Cisco 1811 - Loads default config everytime

    I have a Cisco 1811 that I can't get the configuration to save on. If I make any changes to the configuration and then run the commands "copy run start" or "write memory", after I restart the router it loads a default config file with basically nothing in it. Here is the message that is displayed when I restart it:
    Code:
    Router#reload
    Proceed with reload? [confirm]

    The only thing that stands out is the line that says "Readonly ROMMON initialized", but I'm not sure what that means. Any help would be appreciated.

    Sounds like the config register may NOT be set to 0x2102

    After the router reboots, type" show version". The last line will show what the configuration register is set to. If is not set to 0x2102 (like 0x2142), then...

    Code:
    Router#configure terminal
    Enter configuration commands, one per line. End with CNTL/Z.
    Router(config)#config-register 0x2102
    Router(config)#^Z
    Save your configuration, then reboot.

    If the router still comes up with the default config, then there is something else wrong.

    Good luck!
