    Getting CST to un-cap speed?

      We are all "flying blind" on this, so lets see what Shorty comes back with. As for Sky routers and attenuation, my Sagem will happly bounce around 30 to 35db as it displays noise readings. there is no change in sync speed.
      My Speedtouch is rock steady at 25dB. Both provide a rock steady 16meg. The true attenuation is 22.6dB at 300khz

      That's got me confused

      "True attenuation" - what's that? (attenuation, in this sense being a measure for a given frequency). Are you referring to a test frequency or an approximation of particular ADSL mode frequencies? Edit: just seen your edit. How is testing at 300khz in any sense the "true attenuation"? Still confused.

      I don't have a Sagem so I can't comment from personal experience but "bouncing around" doesn't sound like normal behaviour. The two Netgears and two Linksys I've run on my Sky connection have never changed by more than 0.5db over extended periods of use. Each one of course reports a different attenuation, there being no "standard" measure of attenuation that each router manufacturer adopts.

      Of course attenuation is frequency dependent (before retireing from BT, I took a great deal of interest in my line and the 300khz attenuation test was one I did)
      My point is that routers only give a rough indication of what is going on, for the reasons you say.
