Hi,
I can only assume what you want to do:
You can reset the AP1231 by accessing it via Web browser, navigate to the “AP”-widget and select the “Clear Configuration” action
Alternatively you can access the AP1231 via SSH/console and use the “support”-account (with the password that you specified via the WebGUI) and issue “ssudo firstboot” and confirm this with “y”
Thanks, Regards, Benny
