I am remotely bringing up this site and while changing the EAP's to static IP accidentally typed it in wrong. So instead of192.168.100.xx I set it to 102.168.100.xx.

now I can't adopt it but I do see it in the device list. I tried to forget it and it "forgot" it from the controller but failed to reset it to defaults. 
 

now I no longer see the option to "forget" it again.

i have tried power cycling it using the PoE reset but I cannot adopt it as the adoption fails every time.

i tried to recover by creating a new Vlan with the 102.168.100.1/26 but I still can't adopt it.

i don't have physical access to the device as it is a remote site.

the Controller is an ER7212PC

any advise?
