Today I upgraded from 7.19.6 to 7.20.1 and 5G quit working. The 5G Wifi says that it’s running and so does the interface, but the bridge shows the port status as inactive. I can’t manually restart it so I’m at a loss as to what I’m missing here.
Hoping that it’s just something silly. It worked up until I upgraded it.
I don’t know if this is related but 2.4g comes up quickly on a restart, but 5G has always taken up to 5 min to be seen on the network.
Bridge port status will change to active as soon as first wireless station connects to AP.
So the big question is: does your AP appear on scan list of some wireless stations (e.g. your smart phone) in 5GHz band after restart? Mind the CAC frequencies, AP may have to wait for a minute or 10 minutes before start of transmissions (or multiple that if it happens to detect radar during period of "listening").
You may want to look at 5GHz wifi interface detailed status, if it's in the "listening" state bevause of CAC, it'll say so.
Without seeing your configuration it’s hard to say what could be wrong… But 5GHz coming up after few minutes is a normal behaviour if you are using DFS channel. AP first must scan for any radar in the area before bringing up 5 GHz radio to avoid interfering with the radar.
I think that device reports that port is inactive as there is nothing connected to the 5 GHz radio
EDIT @mkx was faster
I tried using the Quick Set on this so it wasn’t gumming stuff up. I just need it to work without any problems which it usually does. The configuration files don’t show much.

No it doesn’t appear on any scan list from any phone or device that I have. In detail mode it shows that the State of the 5G is running.
Thanks for that… first try at getting my configuration printed… I didn’t know.
This has been resolved now. Apparently, when you use the Quick Set it doesn’t actually set 5G correctly to the 5G frequencies. Once I set the frequencies to 5150-5825 everything popped up on the network the way it was supposed to.
Thank you for giving me some things to look at during this process.
Rule #4, JFYI:
As @jaclaz posted, and in case you didn’t read it, using quickswt with Mikrotik is a no no…
Why ?
Because quickset is known to cause problems when you use it for first setup and then you try to configure something else. Best practice is to leave it alone.
