An Old TV Set Interfered with a Welsh Village's Internet for 18 Months

Engineers have warned us time and again about the problems caused by interference from certain devices. It's rare nowadays to find appliances without proper certifications, but a small Welsh village called Aberhosan experienced what could be considered the worst-case scenario: an old television wreaked havoc on the local ADSL service for 18 months, knocking out connections every day at the same time.

Any exchange of connectivity horror stories quickly becomes a fabulous collection of nightmares. Weeks without service, losing sync every half hour, speed drops, bogus charges... some users even end up wishing it wouldn't rain so the internet keeps working. However, today's story involves a small town in Wales, a couple with an impeccable routine, and a rebellious television.

A Village's Daily Nightmare

The village in question is Aberhosan, a beautiful place with just 400 inhabitants. The local connectivity relies on ADSL technology and is managed by Openreach, a subsidiary of BT Group (formerly British Telecom). But for the past 18 months, Aberhosan didn't enjoy its ADSL—it suffered from it. Every day at seven in the morning, the service would come to its knees. Resident complaints multiplied, and the failures escalated to the point of being unable to use conventional telephone lines.

The company replaced all the cabling, but the problems persisted. Finally, a last-resort decision was made: sending a team of engineers to the village to locate and eliminate the source of conflict. The COVID-19 pandemic complicated matters, but the team was ready to start at six in the morning, under torrential rain, armed with a spectrum analyzer. Their best hypothesis pointed to an effect called SHINE, Single High-level Impulse Noise, which generates an electrical interference pulse when a device is switched on or off.

As expected, the engineers detected the pulse at seven in the morning and traced it to the home of Alun and Elaine Rees. What did they find there? An old 16-inch TV set of the 'Bush' brand, which the couple had bought for 30 pounds and placed in their bedroom. They both switched it on to start the day with a bit of Good Morning Britain, and Mrs. Rees admitted that she loves watching Piers Morgan in the mornings.

With the mystery solved and the promise that the TV would not be used again (something certain residents of the village want to verify on their own after 18 months of frustration), this case serves as a reminder that interferences are more common than we imagine. Christmas lights, microwave ovens, closed-circuit systems, power supplies, and even old RF adapters can interfere with internet and/or cable TV services.
