Resetting to the Default Configuration

Step 9 Type yes, and press Enter to confirm the command.

Note The resetall command is valid for only 2 minutes immediately after the access point reboots. If you do not enter and confirm the resetall command during that 2 minutes, reboot the access point again.

Step 10 After the access point reboots and the Express Setup screen appears, reconfigure the access point by using the terminal emulator or an Internet browser.
