I don't use any channels with a (DFS) after it. 37 shows on an AP but does not seem to work with a STA. I typically use 147, 156 and 164 and do not use auto mode (never) for my APs. I'm noticing every once in a while APs set to channels I would not have put them on or they're in auto-mode and causing trouble. Is this caused by firmware updates or a known firmware number? yes, no, which one?

In my experience with UBNT gear, if you are using a DFS channel and you have not set a channel list, it will jump to a random channel upon detection. This can cause a lot of issues with colocated equipment. I have also found that when you are setting three DFS channels in your list; if it jumps through all three and gets a detection on all of them, it will still jump to a random channel. This is it's alternative to just shutting off for an hour. We now put all DFS APs with a channel list but make sure that the last freq in the channel is a non-DFS channel (whichever one would cause the least amount of disruption to colocated devices). Then, we monitor the frequency with SNMP so that we get a notification if it changes channels.

A STA by default will scan all frequencies if that's what you're asking. All frequencies available to it.

    i answered to quick earlier.  i hadn't read back far enough to
    understand your problem.  I'm actually still confused some what
    your problem is.  A ss of your wireless tab of a radio that your
    talking about would help.  So your saying that on a power beam  m5
    it's set to an auto channel or a channel in the wrong range you
    normally use after a firmware update to 6.04. Is that right?  That
    doesn't make a lot of sense unless the pbe m5 is the AP as the AP
    dictates the channel.  that's where I'm confused the most.

using pbe-m5-400, 6.04 at present, most of the m5 gear are pbe. Am wondering if the update to 6.04 put any of them into auto
    channel mode?

        pretty sure Josh is right on.  on the stations that don't have
        the channels that the newer ones have update the firmware.
         can't remember what version is the oldest that accepts it,
        but 5.6.2 kind of rings a bell.  we have 6.0.4  and I know
        that works.  to add more channels need to  activate UNII rules
        under the system tab on all our m5 gear so that doesn't
        happen.  Nanostation m5s throw me off the most since they do
        some eds channels but not all so it's easier to get lucky and
        work out of the box and forget on them.

        Are you saying the station's frequency is only doing the upper
        channels? Depending on which m5 radio it is, you might not
        have access to 5.1 or 5.4 (pre/post an FCC key...)

                I suggest setting multiple frequencies on the AP so it
                cycles through them.

                    two issues: I've got some m5 gear that seem able
                    to change channels
                    after install on their own. I've found a couple
                    that were in auto mode
                    (never allowed here) and a few more that were in
                    not normal channel
                    selections.  Does this happen as a result of
                    firmware updates?

                    I've noticed on the newer radios they have a wider
                    range of channel
                    selections, but this seems weird as another new
                    one out of same parts
                    order pile won't have the same range.  I'll set
                    the access point for
                    channel 37 and go over to the receive station and
                    it won't see it.
                    Cannot connect them, the station will only go to 147.
