I gave your mobile number a quick call, I'm sorry I didn't get speaking to you. The reason for my call was to see how things are with your connection.
I can see that your current session has been active for the last 9 days. Have you had a chance to connect your router to the master socket?
I've run a few checks on your line and your connection is looking a lot better in terms of error now that the location of the router has changed. I've requested a profile reset with Wholesale and this should see the interleaving reduce on your line.
Please, can you reset your connection over the weekend and let me know if you've seen an improvement?
This is a problem for many people mate there is no fix for it, Just BT being BT, they say they are away of the issue and are trying to fix it so they say.
@PaddyB Here are some screenshots of how its been today
Earlier today with 1 x 1080p youtube video
Earlier today with BBC iPlayer going (not sure on what the bitrate is for iPlayer)
And here is an idle network test which happened to be running whilst I was talking to you on the phone just now
