Powerline tv signal disruptions

Hi

One of my clients asked for my assistance with his private home network infrastructure

I'm not sure if this subject is allowed/accepted within EE since it isn't stricto sensu an IT issue

He has connected his Orange Fiber Livebox to the home electrical outlet using a powerline adapter (200Mb/s) and he did the same at the other end, between twenty and thirty meters, with the Orange TV set-top unit.

His electrical cabling and circuit breaker panel were recently installed

When he watches TV (digital) the image or sound will freeze from time to time.
The halt lasts between one and five seconds and then all returns to normal, sometimes it can last longer.

I suggested that he try more recent powerline plugs, notably 500Mb/s, which I provided him with. Unfortunately this has solved nothing.

I connected a TP Ethernet cable between the Livebox and the TV box and now all is working perfectly, without any disruptions whatsoever.

He is adamant that his electrical installation isn't to blame, and frankly when I saw his electrical panel I didn't notice any dust.

I'm stumped, any ideas, suggestions ?

thanks
yann

What else is using that "AC leg"?
Refrigerator,  Air Conditioner, anything else with a motor/heavy draw, water pump, etc?

thanks for your response

I did take a look  at this and found nothing of particular concern
The electric heaters are on a different leg and circuit breaker panel
The air cons are both switched off
No pumps or electrical appliances of the kind you mentioned

Computers, yes, nearly half a dozen...could they cause such an effect though ?

I seriously doubt it, but you never know (I have seen some "strange" things).   ; )
It still sounds like some kind of interference, though. Since the TP cable seems to be working fine.
A quick look for the Manual comes up with stuff mostly in French(?).

A couple of other thoughts:
- flaky patch cable. try different cables between the Fibre/TV devices and the powerline adapters. Are they Cat5e, at least?
- is it random, or is there a pattern to it?
- is there any way to monitor the connection between the Live Box and the TV Box?
Maybe you can catch what is 'stalling' the signal.
- while Ethernet over Power is better than it used to be, it still has "issues" at times.
Might take some experimenting to find a Make/model that will work the way it is suppose to, in their setup.

Also, a general idea of how his network is put together might help some.
It might need  some kind of QoS from the router. The EoP might be "sensitive" to bandwidth hits. <shrugs>
