I have recently been called to a friends house to look at an issue with their broadband connection being very unreliable, dropping out etc.
Having been on site for an hour broadband seem to work fine, line stats were good etc etc,
and then the phone rang…. and the ADSL dropped
Hmmmmm. Faulty filter? I thought, Pull out a few cupboards to get to the phone socket
All of the Phones etc where plugged directly into the wall socket, the only thing connected to the filter was the USB modem !!!
Apparently they had SKY+ and SKY multiroom installed, and the so called “Engineer” had added some extra sockets etc and reconnected everything in the wrong order and in the process completely screwed the ADSL connection !
