      DLM works best on good lines. If they run DLM on your line you will probably find yourself capped to a very low speed within a few days.

      Regarding your speed; lower your expectations a little. You are aiming too high.

      It was a joke? why has it suddenly jumped up 100kbps?

      I know, but I spend a lot of time on the net so any improvement is welcome. I wonder if BT will run fibre optic over the two miles to get to my house...

      In reality that's 8kB/s. An improvement that you would hardly notice.

      Unless you are capped you should get a different sync every time you restart your router. The speed sync is a speed that the router was able to negotiate at a certain point in time from the exchange. It will vary with the amount of noise on the line.If your router is negotiating a sync at a time when you get a sudden spike in noise then your sync speed will fall down to a low figure like the 256kbps you got. Similarly if while negotiating a sync the noise level on your line goes down suddenly you could end up with a sync of more then 2000kbps.

      Sky's equipment is not SRA (seamless rate adaptation) capable (or enabled). Basically what this means is that your speed does not improve or deteriorate according to the amount of noise on your line in a real time scenario.

      Your router stats suggest that you are loosing sync to the exchange too often. This could be down to the fact that too much data is being pushed down your line. If you leave your router idle you will probably notice that it does not loose sync that often. But as soon as you start downloading stuff it gives in. Think of your line as a thin electrical wire that gets too warm when it's used for too long.

      Sometimes routers can help improve syncs and stability. I don't know if you've been asked this before but what router are you using? It will be great if you can conduct a trace route to bbc.co.uk and copy paste your results here too.

      Recently there have been reports of speeds rising and falling without a resync so I think SRA is enable on some lines. It was always understood that Sky did not use SRA, but that may now not be the case.
