Have been having a few odd issues with our DSL broadband connection, brought to a head by complete failure last Friday.

Much investigation revealed the cause of the complete failure was that some 11 years ago when the house was built some Muppett decided to loop the incoming telephone connection behind the outside plastic cover upwards. Over time this allowed water ingress down the loop of cable into the ‘phone socket inside the house – that was filled with condensation and green corrosion.

However having got things working again it transpired the Downstream noise margin of the router was 12db. But sometimes 25db. Infact usually 25 db in the daytime.

Much investigation eventually “LED” to the problem being caused by the luxion star kitchen spotlights, the sort that can electrocute people. Off to do battle with some ferrite rings methinks.
