Did you know that an old TV set can wreck a whole village's broadband?
by hazel from LinuxQuestions.org on (#58G7T)
It happened recently in a Welsh village called Aberhosan. They had dreadful broadband reception. You had to log in very early in the morning to get a decent speed. Yet BT Openreach engineers couldn't find anything wrong. All their tests showed that the network was working perfectly.
Finally they tried a spectrum analysis technique called Single High-level Impulse NoisE (SHINE) and discovered an interference signal that started at exactly 7.00 AM. They traced it to a specific house, where they discovered an old TV set that was switched on every morning at 7.00 to watch the morning news. The set was switched off permanently and the problem was solved. BT are not giving out the offending address for obvious reasons.
You can read the whole story at https://www.openreach.com/news/secon...entire-village. What it doesn't explain (and what I would very much like to know) is what specifically that TV set was doing that TV sets in general don't do. Any ideas?
