Since the BT "network maintenance" on & about the 23rd June, my 40mbps DS speed has been at 50% and it's getting really irritating. What's changed in the Bolton area? (and I'm 100 yards from the cabinet, so it ain't that). This is a recurring issue (over the last 3 years!!) and nobody no matter how much I get angry ever does anything to actually fix whatever's wrong.
Before I pick the 'phone up and yet again start swearing at someone, is there anyone of any competency that has any clue how to PERMANENTLY fix the problem?
