-- History

I had a long history of connection problems since my house move, which previously had been isolated to a BT engineer not reconnecting my line properly. Now we can connect OK, but at a very slow download speed, even though our sync rates are quite high (high enough for a 2MB connection anyway).

Plusnet Usertools IRC suggested getting PN to check the Bras Profile on their end. I have raised a ticket to that affect (#20652433).

I haven't started fiddling with MTUs or anything yet. Can anyone suggest any additional ways in which to increase my download speed?

If your connection problems are in the past and that SNR margin of 16 dB is stable they should set your target SNR to the default 6 dB which would get your sych rate up close to 6 Mbps (which would be a start!)

Until your proper synch rate is defined it is hard to get to terms with the nitty gritty of improving download speeds
