Old TV set interfered with village’s DSL Internet each day for 18 months | Ars Technica

Having exhausted all other avenues, we wanted to do one final test to see if the fault was being caused by a phenomenon known as SHINE (Single High-level Impulse Noise) where electrical interference is emitted from an appliance that can then have an impact on broadband connectivity.By using a device called a Spectrum Analyzer we walked up and down the village in the torrential rain at 6am to see if we could find an “electrical noise” to support our theory. And at 7am, like clockwork, it happened! Our device picked up a large burst of electrical interference in the village.The source of the “electrical noise” was traced to a property in the village. It turned out that at 7am every morning, the occupant would switch on their old TV which would in turn knock out broadband for the entire village.As you can imagine, when we pointed this out to the resident, they were mortified that their old second-hand TV was the cause of an entire village’s broadband problems, and they immediately agreed to switch it off and not use [it] again.
