How about changing the Ethernet cable or re-crimping connectors? Since this is on 2.4 GHz I would check to see how many Bluetooth devices they may be using especially speakers and such. That frequency hops the band and if enough devices are all hopping around it might be enough to mess with your radio. The hopping sequences are probably too fast to show up on airview. Other ideas to check are things like local transmitters on other RF frequencies. Ham radio operator, business band radio, volunteer firefighter with a radio? One other possible source could be an old cordless phone or two, they have been used on both the 900 and 2.4 GHz bands. Locate them all and replace them with DECT 6.0 phones, those are on their own dedicated 1.8 GHz spectrum. Even one they don’t use in another room will broadcast when the phone rings. Unless you were there as its ringing you would not see it on airview either.

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. On 2017-12-06 01:33 PM, Mitch wrote: Does this site have Perfectly clear line of site? What is the tower AP?

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.

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.

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! On 2017-12-06 09:17 AM, Josh Luthman wrote: Spectrum Analyzer and AirView both show real noise.
