Sync speed drops every evening on BB Unlimited.

I've spoken to a Sky adviser about this and went through all the "connect to the BT socket, fit the right microfilters, reboot the router etc. ...."
Of course, none of this has made any difference.

The issue is that I've just bought a Sky hub and checked the speeds to compare with the old router.
The hub appears to sync a little faster.
From the Router Statistics, it starts at 10,239 kbps, 37.5 dB, 6.2 S/N - then in the late afternoon, it drops to 8,571 kbps, 37.5 dB, 9.1 S/N.
It will stay at that level until I unplug the phone line and reconnect the next day, or later in the evening.

The Sky man said it shouldn't do that and to get back to him if nothing improves.
It hasn't improved and I'm wondering what I should say.
Do you think my line is being subject to Network Management?

Read this which might help you work out the problem. If it's happening every day then this is probably the cause or rather will help you find the cause.
