Multiple router reboots and line speed

[#1]

Estimated line speed was 6MB based on BT info.
Was getting 4MB connection and speeds of around 3.6MB/s.
A few weeks ago, I had router problems and ended up trying different routers and messing about. I then had to leave the country on an emergency and now have come back to find it has dropped to 2.7MB connection and speeds of 2.6MB.
Is there any way to get the line profile reset so I can go back to what it was?

Can you post the full router stats please - when we see those we should be able to give advice.

@omens
I've just been running a few checks and can see the SNR (signal to noise ratio) is quite high for your line (just under 10db) and this has most likely dropped the sync speed somewhat. As the connection is stable I've forced a reset to 6db which should go through within a few hours and should leave to some improvement.

Keep us posted.

SNR is now 7 and download speed has improved to 3.6 MB.

Good stuff!
