I love this story as reported by the BBC about a small village in Wales which was having persistent broadband outages and it was proving difficult to work out what the cause of the problem was. After eighteen months engineers began an investigation after a cable replacement programme did nit fix the issue.
Eventually after sweeping the village with detection devices they narrowed it down to a single house. What was happening was the person in the house was switching on their old TV at 7am every morning and the electrical interference emitted by their second-hand television was affecting the broadband signal.
They have now promised not to turn on the TV anymore!
We know that there are many potential problems with electrical devices interfering with broadband connections, as well as other devices in the home playing havoc with wifi signals as well. It’s never easy.
