Tower is in plain view, no obstructions, is set to 2412Mhz, 20Mhz bw at
less than 3 miles away. Tower is a rocketM2 with a 120degree sector
antenna am-2g15-120. There are 24 users connected. Problem first
started showing up when there were maybe 5 users over 2 years ago.
There is only 1 user with this problem and there are at least 6 users
within easy sight of this 1 user who have no problems. Problem seems to
be specific to this one location, I suspect it has something to do with
pump-motors as they turn on at random times and there are several in the
nearby area. How do I prove the problem? Anybody know what kind of
test equipment would spot motor and/or power noise? An old black and
white TV used to be pretty useful at picking up un-grounded motor-noise,
I don't have one and we don't have a tv station that broadcasts
something an old-tv would even tune to.
The one-time I saw the problem while I was there and airview showed
nothing useful. Channel 1 and 11 were empty, actually all the channels
were empty when there should have been something. I don't know what
could essentially block signal, which is kind of what I saw.

Does this site have Perfectly clear line of site? What is the tower AP?
If clear line of site and V/H AP try setting the CPE to the Horizontal
and see if that clears it up
This has worked a few times for me
If not you may need to rent an Anritzu and set it to record for a few
days to see what the
interference is

I think I've tried everything mentioned at least once. I moved it to
a NSM900 Loco for awhile from a different tower. I've had NSM2,
NSM2Loco, AirGridM2 and AirGridM2HP and NanoBeamM2, Maybe next try a
PowerbeamM2-400? Don't have an M5 tower near here yet. Client uses
an Air-Router set to channel 6. Everything in large house uses
channel 6 to talk to Air-Router. Have changed the Router to Gateways
and even other brands. Always the same intermittent problem with
connecting to internet.
Presently, channel width is 20Mhz (everyone gets this setting via
tower) on channel #1 (2412Mhz) signal is: -59 and using an
airgridM2HP. PWDOG set to tower IP 300 seconds.
FYI--I've had this problem for 2 years. Couldn't resolve it and
stopped service. Customer wants our service and wants problem resolved.

Two things I've done when experiencing odd issues at one site that
worked for me.
1. Check customer router settings. Reduce channel width to 20
mhz on both 2.4 and 5 only and set channels to ones you don't use.
I've had some customer routers blasting at 40 or 80 mhz channel
width. Once I reduced, both my radio stats and their experience
improved. I've had this on multiple customers. Not sure why default
is 80mhz channel width.
2. Redirect the dish to change the signal strength. I had a
similar case and as last resort I made the signal worse and it
worked. Was in mid 50's and moved to low to mid 60's and issue
disappeared. I even tried turning the power down due to the strong
signal and still didn't work till I moved the dish.
Somebody on here, mentioned during my similar interferemce issue,
that something could be facing this one dish that is new in the area
and the direct inference is impacting the service. It worked and no
idea what it was picking up.
Hope that helps.

It's just the one customer. Neighbors to each side are just fine.
Neighbors are about 1/4 mile away on same hillside in quasi-rural
area. There are no other WISPs in area, no airFiber that I've
found. AirView shows nothing worth getting excited about when
problem isn't happening, when problem is happening Airview is not
accessible as unit is not responding. Rarely has problem occurred
while I'm on the premises and goes away before I can zero in on it.
I'm suspecting large pumps, old transformers, bad neutral? How to
prove and stop wasting time and money on one customer? Pulling hair
time!

Spectrum Analyzer and AirView both show real noise.
You said you changed bands at the customer site, are there other
customers on those APs that are having issues or is it this one guy?

I have on two occasions tried to cross the path of an AirFiber5
and had the signal completely blocked. Like Rory said they
don't show up on Site Surveys or noise figures, but are very
apparent in AirView.

Subject: [Ubnt_users] cannot find interference source
Have a client that is difficult to login to at times,
service for them seems to quit. Has good signal strength.
Have changed the radio to different models and frequencies
and connected to different towers. It's like some kind of
barrier at random times is erected between house and
tower. Site survey and spectrum analyzer never show
anything remotely definitive as to possible cause or source
of trouble. Could problem be noisy electrical transformers
or well pumps and what low-cost equipment would I need to
find it?
