Forcing them both onto the sector, they have now been stable for over a
day. Weird. Some sort of issue with Mu-MIMO and the smart antenna?
Like it was trying to talk to both SM's at the same time but because
they were so close they were interfering with each other?

No, I forced them both to the same antenna. I figured if it was
timing thing, then both on the same antenna should fix that.
They've been up for the last hour since I forced them to the sector,
reporting same distance and identical Signal levels.

Did you force one to each antenna?

Forcing them to the smart antenna didn't help, just forced them
to the sector to see what happens.

If you're compounding it with multipath, those tiny
timeslices probably have more overlap to the same antenna. I
dont know the math so I'm probably wrong

I didn't think of that if they're using the 2 separate
uplink antennas. But I would have thought the scheduler
would keep that from happening.
I just forced them both to the smart antenna. We'll see
what happens.

If distance is fluctuating it could be multipath,
eliminating that as much as possible will help.
but having them on two different uplink antennas may
help ensure the AP isnt "blinded" on the uplink.
the AP Rx should be pretty much even, if theyre not and
one is fluctuating more than the other it may be the
multipath culprit. I dont know if theres shrouds for
these like ubnt had, but if you have one of the old NSM
shrouds you could try affixing it with the gap away from
the other radio to shield the two somewhat. It wont fit
all the way around but could give you an idea of whether
you should go to the machine shop. I dont know if
RFArmor is still a thing or not

Yes, distance is fluctuating. Right now they're
showing equal distance. And both re-reged within 30
seconds of each other 10 minutes ago.
Do you mean set the preferred AP?
Don't have a good way to get vertical separation.

can also try locking one to the sector

Is the SM distance fluctuating? Can you
get vertical separation, 18 inches?

I have a rooftop that has an existing
Force300-25 radio on it for
several months. I just added a new
Force300-25 radio on a new mount
next to it, so they are separated by a few
feet horizontally. Both
radios are now re-associating randomly to
the EPMP3000Ap with Beam
Steering Antenna every couple hours. Has
anyone else seen this? These
are the only 2 SM's on the AP that are
dropping. In the AP wireless
table, it also thinks that they are 0.5
miles different in distance.
Signal levels are exactly the same.
I've seen the Signal levels do strange
things when EPMP SM's are close
together, but I haven't seen the radios
make each other drop out before.
