I've got a UniFi 48 port PoE switch that will not get or pass DHCP addresses from any source.
For example, the switch itself WAS set to a static IP address. I noticed that every device connected to it suddenly could not access the network. I plugged in a laptop to the switch and discovered I could not get DHCP. So I did what I shouldn't have done, and I "forgot" the switch in the controller. From that point on it hasn't connected back to the network. I have pulled the switch out and replaced it with a new one which works fine, but in my lab the old switch behaves the same way.
I have factory reset using the reset button but no change. I am thinking maybe a firmware update went sideways and that caused it. I would like to try to upgrade it but the only way I can login is using the console port.
I would like to be able to either set a permanent or "sticky" static IP address to the switch so that it doesn't constantly override with the 192.168.1.20 address and/or upgrade the firmware via CLI (either SSH or console port if possible) once I get a static IP to hold.
