Signal of -89 sucks big time.

Also noticed you are using DFS. 6 miles in DFS band is a stretch too. If you have channel at the AP end set to auto it could explain why after you unplugged it it didn't work afterwards. I would stick to a high power channel.

Silly question but what is DFS? I understand that it is showing channel with DFS but it was during the troubleshooting that we picked that one.

I am going to try and sound nice here - these radios need to be installed by professional installers, and by ticking the agreement when you first log into them, you should know what DFS is.

From the ubnt instruction manual / wiki
Enable DFS: DFS is the part of the IEEE 802.11h wireless standard. Enable DFS option allows to enable/disable DFS support (applicable to M5 series only). DFS may be mandatory in some regulatory domains and should be tuned according to the regulations of the selected country. Please consult compliance guide and official regulations authorities for further explanation of compliance requirements for the country where AirOS v5.3 based device is installed.

Dynamic Frequency Selection will listen on the channel selected for a radar system - such as aeroplane tracking at airports, weather monitoring etc. A link can interfere with a radar system many many miles away. So when it starts up, it will listen for a radar and if it detects one, it changes to another channel.

To elaborate on what was said above - the DFS channels in many countries usually have lower output power limits, so that could be why the signal level has gone down - but its a big drop so im not entirely sure it is.
