    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).

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

    The Access Point is OpenWRT and operate in

    @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?

    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.

    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.
