I had some 6-7 years trouble free Internet with Tiscali .. and then it became Talktalk … 
That's when the crap started … Line dropouts, no broadband, reset router etc. etc. etc.
Went on for months off and on …
'Engineer' came and fitted new router, didn't work so he disappeared for 3 days and having spent 3 lifetimes on their useless phone line another engineer came and fitted another new router which sort of worked, for a day or so, then back to situation normal ie,. no Internet.
Problems apparently caused by internal sockets / wiring / filters etc. etc. ie. Any damn thing you like except Talktalk ..
So, in Dec. 2013 I dumped the incompetent Goons and went to PlusNet.
Ever since then my apparently shaky set-up has worked quite well for some reason …
