News from the BBC of a SHINE (single high-level impulse noise)[*] that interfered with a Welsh village's internet connection on a daily basis.
The mystery of why an entire village lost its broadband every morning at 7am was solved when engineers discovered an old television was to blame.
[...] After 18 months engineers began an investigation after a cable replacement programme failed to fix the issue.
[...] Openreach engineers were baffled by the continuous problem and it wasn't until they used a monitoring device that they found the fault.
The householder would switch their TV set on at 7am every morning[sic] - and electrical interference emitted by their second-hand television was affecting the broadband signal.
The owner, who does not want to be identified, was "mortified" to find out their old TV was causing the problem, according to Openreach.
"They immediately agreed to switch it off and not use it again," said engineer Michael Jones.
While some properties in the surrounding area have Fibre to the Premises, several homes in the Aberhosan area are still limited to using copper-based ADSL connections.

This is RF spewed out by the TV, going to a phone line as opposed to the coax the TV is using. Maybe the phone line was only an inch by the TV or something like that. LED lightbulbs and power adapters are not something you can compare this to. A large old tube TV can be close to a kilowatt of power. It can create a huge magnetic field that hits an unshielded phone wire.
As far a finding the source of RF - possibly 18 months is too long, but sound fine to me. It takes months of ignored reports to even look into the problem. Then they send engineers to the houses of people reporting the issue to fix their home network. Then after many reports they start looking on their end. By the time you identify the shared wire shit is coming from, it's been months. Now which house is it? How do you know it's RF - there's many possible issues, including your own equipment being the cause.
