Re: Sky BB speed issues - improving a poor noise margin

Sky appear to put many people on G.DMT/Interleave, with a capped max speed, rather than ADSL2+/FastPath.

They do this if they feel that your line is too poor for ADSL2+, too noisy.

Sky's G.DMT can AFAIK go up to around 12mbps I think, while Sky's ADSL2+ currently tops out at 16mbps.




When I first connected, I only squeezed a bit over 5mbps out of it, because of my high attenuation, & my low noise margin.

After removing the ring wire, my noise margin increased, enabling me to connect at a higher speed - although it topped out at 8096kbps, as it had been capped by Sky at 8096 & was on G.DMT.


"Tier 3" is the 3rd level of Sky BB tech support...... they can, if you badger them enough, & jump through hoops with Tier 1 & Tier 2 first, switch you from speed capped G.DMT to ADSL2+.

However, if your speed sucks anyway there is little point.
