If the device was associated with ZD, you have to install standalone software to the AP. If not it will revert back to the old settings, I also had to get a separate power supply to ensure I was not on the network where I have ZD installed.
Also, ensure your laptop is on the same subnet as the AP, I used 192.168.0.15, 255.255.255.0 I connected the AP directly into my laptop.
Once the AP is reset, login to the AP's UI using the
default IP - 192.168.0.1 and the user name is super Password is : sp-admin
