Am I Being Sold Nonsense....? Not on ADSL2!

Ok, if it's uncapped, wouldn't that be reflected in the MySky connection details page? There, it says my line is set to 4096/800.

That'll just likely show what DLM profiled it to. It won't reflect manual re-profiles made.

Here we go, just reproduced my stats. Test socket, Sky router, decent filter.

ADSL Link Downstream Upstream
Connection Speed 4898 kbps 796 kbps
Line Attenuation 46.0 dB 27.4 dB
Noise Margin 7.1 dB 13.9 dB

From Sky's site:
Download Speed
Your connection has been set to a download speed of up to
4.9Mb (5024Kb)
Upload Speed
Your connection has been set to an upload speed of up to
0.8Mb (800Kb)

That's the bit that surprised me; "set to" an upload speed of 4.9mbps sort of implies a cap?

Another forum I posted on for some help has suggested that with a noise margin of 7.1dB and a target of 7dB, the modem is selecting a lower sync in order to make sure it can achieve its target SNR, and that my line is just too noisy and there's nothing I can do about it.

Any thoughts? I'd like them to set it to 10240/800 and maybe just see what happens. Or is there a time of day where the SNR's likely to be better and I could resync and see what happens?

If Sky sent an e-mail and confirmed that the line is already set to 10240/800, then I'd go by that rather than what your MySky suggests. If you want to call up to confirm what the line is set to, then go for it, but it'll probably be a waste of time in regards to improving anything.

Target SNR is 7dB. If the line is uncapped to 10240/800 adsl2plus, provided there isn't high INP on the line (which it will only be 1symbol anyway with that profile), you're getting as much as possible.

Just to prove the point about MySky and it not possibly not showing manual profiles -

Speed Estimate

When you purchased Sky Broadband, we estimated that the maximum download speed for your line was: 0.5Mb

My actual stats (after numerous reconfigs which is now set to 2784/896 on the dot, not 8192/384):

ADSL Link Downstream Upstream
Connection Speed 2784 kbps 896 kbps
Line Attenuation 61.5db 31.5db
