Well I'm stumped on how to proceed.
Client Has had bad Wifi for ever so i put in two Ubnt UAP-LR in a 2000 Sqft house full bars everywhere. Thought i was done. Calls back Still Drops out every once and a while. Also the HAM radio guys voice comes over my speakers sometimes. (zone 2 of a Denon). I asked a guy who asked a guy and he said put Toroidal Chokes on the power and data lines. Said the HAM guy would do it. HAM guy is not friendly. So trying to help i put Ferite Beads on the Data Wires. She is still having issues. Therefore Help What should i Do?

Call FCC.

Client did that. No luck

Quote from Client
I called the FCC and they said they don’t deal with ham radio type interference anymore

drywall screw through the antenna cable

Along with being a HAM radio Guy. He's a Nut. There are at least 7 cameras that i can see from the street and client says that he has the perimeter covered with Microphones.

use ruckus with RF rejection?

Usually! HAM radio is not going to cause any interference. So either his equipment is not installed properly (the grounding is extremely important in this regard to transceivers and antennas), he has defective equipment, or he is running an illegal amplifier.
1st = you need to get a spectral analyzer to actually see the interference. Metageek has a nice package for WiFi analysis that includes a 'device finder' antenna to track down interference. This will allow you to actually point the finger at the neighbor as the problem. Or discover it was actually something in the customer's own house causing the problem.

If! it is the HAM neighbor causing the problems:
This is ABSOLUTELY an FCC issue. I would call them myself and talk to someone about it. If some idiot tries to blow you off, demand to speak to their supervisor! Just because someone doesn't want to do their job, doesn't mean they can get away with it. It just might require a LOT of work on your part to get them in trouble.
There is NOTHING you can do at the customer's house, to fix this - if the problem is one of the 3 mentioned above with the neighbor. If you truly can't get the FCC to get off their arse to do their job: Start filing police reports with the sheriff's office. They will get sick of it, the neighbor will get sick of having a deputy knock on his door, and someone somewhere in the Sheriff's department is going to chew someone's arse out at the FCC until they send someone to look at the problem and give them authorization to do something.

OH! The voice over the speakers:
This could be a design issue with the Zone 2 receiver. In which case, not much you can do about it. But if the HAM guy is running an illegal amp, then this could be a sign of that and require the above mentioned craziness.

And just to mention: To do all the above, would require an enormous amount of time & effort. Is this customer a good friend? Or are they going to be paying you very well? Otherwise, they might need to just live with it.

Adding more: They could wrap their house in a faraday shield. This would solve any external problems. Would be VERY expensive. And they would never pickup terrestrial signals in the house again (i.e. AM/FM radio, OTA TV, etc...).

I would absolutely put ferrite chokes on the wires... the Zone 2 speaker wires. If the speaker terminals screw down, make sure they are TIGHT.

You say

This may bother you, but I don't understand why your client cares about this, unless you live together.

Along with the other phone calls recommended to you, try calling the ARRL (not AARP) to see if they can suggest something. They're all hams and they're interested in how they are perceived.

By the way, you don't characterize the wifi problems, as to, for instance time of day, regularity or randomness, or any other detail that might help take the ham off the hook. It might not be him, you know!

Proceed with Warfare.

Is Zone 2 amplified by the Denon AVR or a separate amplifier? If the former, make sure the house's electric service is well grounded. Loose connections at the receptacles, intermediate and at the panel can allow RF to infiltrate the audio equipment. In addition, the house's grounding stakes need to be deep enough and on a single conductor from the panel.

Where is the antenna located WRT the room with the AV and network equipment? If the outside wall of the room is close to his antenna and it's a single story house, it's going to be difficult to stop this.

I don't suppose there's an HOA that you can turn loose on this guy, eh? Maybe a neighborhood petition would help- ask others if they have the same problem and since he wants to be a dick, make it a game.

How do you know he is a HAM radio guy?
You can use his name to get a call sign. Not for this board to post.
He might be an illegal CB operator with an amp.
Take a picture of the outside antenna and I will tell you exactly
what it is.
Try one more time or talk to the wife to see if you can get a resolution with him.
If not, a noise generator on the band he is operating at will fix it.

You can get the FCC out there if you tell them he may be transmitting with 1-2000 watts.

What version of unifi are you using, loads of issues with certain versions similar to what you describe.

Dupe...

It is true that the UAP-LR's have more transmit power and possibly a better receiver, but blasting the WiFi can saturate the WiFi receivers and cause issues in nearby clients. Also, if the client transmitter is weak, their reply will not reach the access point -- regardless of the access point's transmit power. Make sure that you are using latest UAP-LR firmware. (from a couple weeks ago)

With respect to the Ham, make sure that your wire dress is good. Don't have wires dangling all over the place because this will simply act as an antenna and  increase the signal level that the equipment must reject. Minimize the interconnect length, bundle any slack and keep it close to the unit.

Generally, I don't like to ground HiFi units, because this usually causes more trouble than it cures, but grounding might be helpful in this case.

Install a high quality surge suppressor in an attempt to scrub the Ham from the power line. Be anal about bundling the power cords.

Install shorting plugs on all unused inputs.

I don't know about this receiver, but certain units have an unreal sensitivity to RF energy.

A while back I had an experience with a receiver detecting foreign language broadcasts. There was a Ham next door so I blamed the Ham and managed to minimize the situation with wire dress. Some weeks later I encountered the same model receiver detecting the same foreign language broadcasts -- almost 20 miles from the first receiver! While I had suspected that the Ham was running some sort of rogue linear, this amp would not be powerful enough to hit another customer 20 miles distant. And, there was an FCC monitoring station between the two locations.

My analysis was that there was some sort of freaky resonance in the receiver that increased its sensitivity to a particular shortwave frequency. I beefed up the receiver's internal ground buss and added some extra power supply bypass capacitors with good high frequency performance. It was a "buckshot" approach, but it changed the resonance enough to block the shortwave pickup.

Does the Denon use electronic source switching? In few cases I've seen nonlinear behavior in CMOS input switches. If this is your situation, you'll need to reduce the strength of the Ham's signal before it reaches the switch. Good wire dress can help, along with some small bypass capacitors on the inputs.

Don't overlook the possibility that an input device, such as a cable box, DVD player, etc. is responding poorly to the Ham's signal and that the issue is really with the input device adding the Ham's signal to its own output. In this case no amount of rework on the receiver will help because the Ham's signal is already bundled with the content before the content is sent to the receiver.

Edit: A new firmware for the UAP-LR was issued June 15. This release is not yet bundled with the GA (General Availability) controller, but this should happen soon.

A couple thoughts on this--

The ham guy is licensed. As long as his is following the rules, he has the right to the spectrum he is using, even at 1-2000 watts.

You, and your gear (wifi) is not licensed. It falls under FCC part 15 (unlicensed operations) which clearly states that is "not to emit unwanted interference, and must accept all unwanted interference". Short version: Too bad.

Now, with that said, most ham guys are friendly, helpful, and want to apply knowledge. If the ham will not help, certainly the local ham community will. ARRL is a good suggestion. Quality chokes are the way to go here.
