Spoke to a guy names Martin from BT
Told me as far as he was aware the Halifax Exchange Has no congestion issues.
I cant see a problem with my setup at home,as the speeds are fine during the day,just goes to pot about 4pm till after Midnight.
Anyway he was going to call out an enginner, but i said i will monitor it for anaother week to see if things improve.
Martin will ring back in a weeks time,take it from there.
Its Pretty Dire tonight
Today i put a brand new filter plate on the bt box also a brand new cable to the router..
Rules out my internal wiring
To be honest cant see how it can be my wiring as the speeds are great during the day just between 4pm to midinght
Getting cheesed off now
Still think it is congestion and I would suggest you go back to mod who is helping you. If you have an email from a mod then just reply to that and get mod help again
