If your switches are ToughSwitches then yes, use the reporting interfaces to view the traffic and other things.
But typically, WiFi issues are best solved using a mobile app like Wifi Analyzer on Android... and just moving the WiFi channel frequencies to less populated parts of the spectrum. The vast majority of WiFi issues are simply "someone else transmitting on the same frequency", and won't be related to you having several switches in the setup. If other people have added WiFi in your vicinity since you installed the Unifi, this is likely the issue.
On an upside though, most default channels are coded into BT boxes, etc... so if you pick a spare bit of frequency manually you'll always be in the clear and they'll always stomp over each other.
I'm in a tower block... lots of WiFi above, below, to the sides... have no issues with my Unifi.
I'm not convinced the issue is with the wi-fi. It's connecting at full strength. I suspect it may be one of the switches but I don't know how to test that.
Not easily is the unfortunate answer, especially if the switches have no reporting interfaces. You would have to rather primitively test each hardware route through the switch, but the effort involved is such that I'd just get a better switch. Not helpful I know.
