Hi Harrison,
You can use this method;
Reset the AP-Cisco IOS Software
Complete the steps in this section in order to reset Cisco IOS Software-based APs.
Note: Cisco IOS Software-based APs have a default configuration that includes a username and password combination. Both the username and password are "Cisco", which is case-sensitive. After you reset to factory defaults, be prepared to give "Cisco" as both the username and password when you are prompted by either the GUI or the command-line interface (CLI).
If the privileged command prompt ap# is available in the CLI, the write erase command and the reload command erase the startup configuration and reset the unit.
If the GUI is available, choose System Software > System Configuration. Press the Reset to Defaults button.
If neither the GUI nor the CLI is available with sufficient privileges, complete these instructions in order to use the Mode button:
Disconnect power from the AP.
Disconnect the power jack for external power or the Ethernet cable for inline power.
Press and hold the MODE button while you reconnect power to the AP.
Hold the MODE button until the Status LED turns amber, and then release the button.
The Status LED turns amber in approximately 1 to 2 seconds.
After the AP reboots, reconfigure the AP and use the web browser interface, the Telnet interface, or Cisco IOS Software commands.
Note: The AP is configured with the factory default values that include:
The IP address, which is set to receive an IP address with DHCP
The default username and password, "Cisco"
