That explains some of what I may be seeing

Newer firmware do lose some of the edge frequencies on certain devices, after updating. I think it was just on Powerbeams of a certain hardware revision. Newer models all work at the edge bands if I recall. I think you have to activate the UNII rules for that to happen though, but I could be wrong. For example, some of the M5 firmwares do not allow 5840, but still allow 5835. Those same models do not allow 5735 but do allow 5840. I am not sure what the behavior of the device is when you upgrade to those firmwares if it sits on the edge band at the time of the update and is in AP mode, as we only use them for CPEs. We ended up moving all of our APs off of those edge bands after getting a large batch of CPEs that couldn't 'see' the APs.

No. I have never seen a firmware update switch an AP into 'auto' mode. If you are not using DFS then I have no idea what would cause that.

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.
