Engineers solved a mystery that left villagers with broadband issues for 18 months.
Connectivity can be poor with slow speeds starting at 7:00 am, causing problems for households trying to connect.
Openreach engineers replaced cables at Aberhosan, Powys, but that didn’t solve the problem, so they had to think again.
They then switched to a monitoring device and discovered the fault was due to electrical interference from an owner’s used television.
The owner, who does not want to be identified, was “mortified” to discover that his old television was causing the problem, according to Openreach.
“They immediately agreed to turn it off and stop using it,” said engineer Michael Jones.
Engineers walked around the village with a monitor called a spectrum analyzer to try and find any “electrical noise” to help identify the problem.
“At 7 am, like clockwork, it happened,” Mr Jones said.
“Our device detected a large burst of electrical interference in the village.
“It turned out that at 7 a.m. each morning, the occupants would turn on their old television sets, which in turn would shut down broadband for the whole village. ”
The TV was found to emit a single High Level Impulse Noise (SHINE), causing electrical interference in other devices.
Mr Jones said the problem had not returned since the fault was identified.
What Can Cause Broadband Problems?
Suzanne Rutherford, Openreach’s chief engineer for Wales, said anything that includes electrical components – from outdoor lights to microwaves – can potentially impact broadband connections.
“We are simply advising the public to make sure their electrical appliances are properly certified and meet current UK standards,” she said.
“And if you have a problem, report it to your service provider first so we can investigate. “
