Interleaved vs fastpath test

My line is fairly noisy, so in past times I've struggled with gaming mode enabled - line was unstable and kept dropping down to ADSL2 modulation

I haven't tried since BT replaced my dropwire and the line has become alot more stable, so though I would give it a go

Just changed over and here are the stats before and after - now to see if it remains stable

Ooo look, your bandwidth increases when you're on Fastpath

Good luck.

So it does (bandwidth increases on fastpath that is)

And look, it's increased even more

For that attenuation, I'd expect a sync of 13466

So would I, but sadly something is preventing that from happening

What does the bitloading look like on e.g. the latest Routerstats?

Eek, lots of gaps there. Wonder what's causing it.....
Have you got any RFI filters on there?

No RF filters
Plugged into master socket - not much difference in test socket
Ring wire removed
Internal wiring checked by BT to be fine
NTE5 replaced
Dropwire replaced
Similar results with other routers - i.e 2Wire & DG834GT
Different filters tried
Different RJ11's tried
Ferrites tried in different configurations

At about 5pm when I resynced, DMT was showing 10 gaps - now up to 18 gaps mostly corresponding with MW radio stations
