Yes our Hub3 does exactly the same.
The ultimate fix is supply your own router & access points & operate the Hub in Modem mode. We should not need to do that in 2023.
VM admitted this week that the WiFi policy applied to the Hubs re-enables both 2.5 & 5Ghz, if you turn either or both off in a few hours they re-enable.
We can add manual channel wander also reverting to 20/40/80 on 5Ghz to the list.
One that we see daily on this forum is Hubs(3/4/5) that will not connect a 2.4Ghz device ( e.g an Epson, HP or Canon printer), today a Hub 5 owner used WiFi analyser on a phone and reported their printer can't connect because the Hub 5 2.4Ghz WiFi signal is not transmitting. This one is a real pain as lots of IoTs, security cameras, printers, entry level mobiles, older laptop + Kindles require 2.4Ghz.
