If you specify a non-DFS channel, then it probably works.
I have a 'tab' open on [1] and [2] to research it further, but haven't
gotten around to it yet. So selecting a non-DFS channel is a workaround
but hopefully there is also an actual solution.

Asking on the OpenWrt forums is more likely to find a solution to this
problem then on this list (but maybe you're lucky).

Hello,

i have a Raspi 3B+ and try to connect to WIFI 5G.

The Access Point is OpenWRT and operate in
AC mode, Channel 64 (5320 MHz).

There is no Wifi 5G found.
I have no idea what is wrong there.

@Tim: 3B+ has b/g/n/ac dual band 2.4/5 GHz see https://en.wikipedia.org/wiki/Raspberry_Pi#Specifications

@Diederik I'am not sure if OpenWRT is the Problem. Other clients can
connect to 5G Wifi. Or did you mean that Raspi does not Support DFS?

If you're using the built-in wifi on the 3B, then I'm pretty sure it's
2.4GHz only.  You'll need to use an add-on USB wifi adapter if you want
5GHz (maybe SDIO is also possible).

Its been yonks since I retired my 3b, but I don't recall it having 5G in
its radio, only the 2G 11 channel. And I can't scan with the rpi4b that replaced it, nasty neighbor was stealing my bandwidth to the tune of
80Gigs a month, so all radios are disabled here. Karma caught up to him
and he did a year n the gov's economy hotel. His woman threw him out,
but I've never bothered to turn my radios back on, lots more peaceful
that way when you need a piece of cat6 to get into my machines.


Cheers, Gene Heskett.

I had to put my OpenWrt router on a non-DFS channel for 5G, otherwise I couldn't connect to it. But if it works for you, then it's likely a different issue.
