Getting better speeds

[Keiran2K8]

You could try, Say that you have a Ticket Open and you would like to speak to them..

Dont mention the utility, Just say that you have a excellent line and BT have tested it and its perfect, And you want out of the G.DMT.

Once the CAP is off, I havent heard of Sky putting it back on.

Figured it was pointless to wait so phoned back and gave them the ticket number. I was told Tier 3 are very busy with waiting times of up to 45 minutes. I've been put on a "priority callback", I'll give them until tomorrow then I'll phone up and just wait.....

I dread to think how much this is all costing, I must have been on the phone to them for at least an hour, probably more so far!

Im sure if there was a utility that could uncap you on the Net - noone would need to call Sky, Just pop a Visit to SkyUser.co.uk

What do you mean? You have confused me, are you saying there is a way to un-cap my connection without bothering with Sky tier 3?

Just got off the phone to Tier 3, spoke to a nice Scottish chap who was very helpful. He tried numerous options on my line including ADSL2+ and ADSL without any caps to see what the line can take.

He wasn't entirely happy but he has agreed to put me on ADSL2+ with a connection speed of 15323kbps. The line attenuation is at 26.5 and my noise margin set to 9.6.

When he was running tests my line synced at 16238kbps but that was without error correction or something. When he put that on, it gave me the 15323kbps I have now. He explained I seem to be getting errors that are above the threshold he would like to see for ADSL2+ and would normally leave me on ADSL with 8096kbps. As I requested it he has said I can stay on ADSL2+ but if I have any issues over the next 24-48 hours to call back and be put on G.DMT again.

I've been on ADSL2+ for about half an hour now, and my router stats are below. What do you guys think? Should I be okay on ADSL2+? He mentioned something about a build up of errors which might cause problems with disconnections that I didn't completely understand.

Yes your errors are a bit too high for comfort. Chances are you'll find your connection slows to a crawl after a few days and you'll have to reboot to "flush" them.

My recommendation would be to boost your noise margin a little higher so it never drops below ~10-12db. This of course means that at the quiet times of day you'll have a noise margin of 13-15db or so and a lower sync speed than currently but still considerably faster than 8096kbps.

If you do find your connection can't cope with ADSL2+ (which I doubt) then don't ask T3 to switch you to G.DMT - do it yourself and stay in control.

Right, I've set my noise margin to 11db and my new stats are:

Downstream:
Connection Speed - 12672 kbps
Line Attenuation - 26.5 db
Noise Margin - 14.2 db

Upstream:
Connection speed - 764 kbps
Line Attenuation - 14.9 db
Noise Margin - 12.0 db

I'll see how it goes for a couple of days, then decrease the noise margin and repeat. It's good to be in control!

I tired the old broadband speed checker and it reported speeds of just over 10Mbps. Not too shabby, I'm happy with that if it remains stable. Hopefully the image should appear in my sig if I've set it up right!
