News from the BBC [bbc.co.uk] of a SHINE (single high-level impulse noise) that interfered with a villages internet connection on a daily basis.
Engineers have solved a mystery which left villagers with broadband problems for 18 months.
Connectivity could be poor along with slow speeds from 07:00, causing issues for households trying to get online.
Openreach engineers replaced cables at Aberhosan, Powys, but it did not fix the problem so they had to think again.
They then switched to a monitoring device and found the fault was due to electrical interference emitted by a householder's second-hand television.
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 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.
