Long-term investigation of unstable input

Separate area for niche lag issues including unexpected causes and/or electromagnetic interference (ECC = retransmits = lag). Interference (EMI, EMF) of all kinds (wired, wireless, external, internal, environment, bad component) can cause error-correction latencies like a bad modem connection. Troubleshooting may require university degree. Your lag issue is likely not EMI. Please read this before entering sub-forum.

We have a TN-C-S electrical system serving four houses. If a coaxial cable is severed at one of the other houses, could it affect the electricity supply in my home???

Unplugging and reconnecting cables and devices, switching lights and fans on and off etc now changes nothing. The issue is related to coax for me and im sure it is for most people
My house has coaxial cables connected to the TV in rooms separate from my PC; nothing in the PC room, including the internet, has coaxial cables. The idea is to remove all the coaxial cables or connect just one to my PC. Could you explain how we can do this?

Could you provide a little more detail, please?
I'm not sure what you mean by saying the issue is related to Coax.

Leave it...
If you don't know what you are doing or don't know how to cut/disconnect coax temporarily.

There should not be any current on the coax cable.

Ask someone who knows how to do it.

I connected a coax cable coming from my TV antenna into a wall coax port.

I have multiple open coax ports that has no terminator cap or are unplugged, here is sweden we have 3 coax connections in each outlet.. I wonder if this could be it

It could be bro, the coax stuff is the only thing that maintains the change, I also have multiple open coax ports left in the house so I'm gonna try terminators when they arrive. For now keeping a connection from the attic tv antenna to my downstairs living room coax port via a standard coax cable is keeping my pc good, terminators might be a different effect on things considering they cancel out the line so we'll see

Could a disconnected coaxial cable in my home affect this? I have several coaxial antenna cables, but they are disconnected from the TV (even though the cables themselves are still there).
