Hello Jay,
Please access the AP through the console port using a console cable (any console cable should work). The baud rate (speed) is 115200. Are you able to get to the login prompt? If so, reset the unit back to factory default using the following credentials:
Username: reset
PW: FactoryDefault
Once the unit reboots, log back in, change the password and run the following command:
>en
#sh ip int br
This will provide you with the available IP addresses to reach the unit with.
Thank you,
Chris
