If you want to reset the Cisco Aironet 1250 Access Point to factory default settings you have to use “Write erase or erase/all nvram” command, these commands resets the Cisco Aironet 1250 Access Point to factory default settings except the static IP Configured. This feature is really helpful if you reset the Cisco Aironet 1250 Access Point accidentally. Still you will have an option to access Cisco Aironet 1250 Access Point  using a web browser interface.

Mindful thinking from Cisco.
