Hi, can you just confirm the exact model you have

Hi, so just confirming the firmware you are installing is as below, you will need to do this via SSH, doing it from the controller will/may not work

http://dl.ui.com/unifi/firmware/BZ2/4.0.69.10871/BZ.ar7240.v4.0.69.10871.191109.0532.bin

I don't how to update via ssh. 

Hi, ssh into the device, it should be ubnt/ubnt for creds, then issue a "help" command and it should tell you what commands are available, but you want to issue the following

upgrade http://dl.ui.com/unifi/firmware/BZ2/4.0.69.10871/BZ.ar7240.v4.0.69.10871.191109.0532.bin

Note how I have adjusted the URL to http, otherwise it will fail, this update also presumes the AP can see the internet and has DNS resolution
