      Ok thanks, but now I've switched over the MTU to 1500 and my results are dismal - Download Speed: 2858 kbps (357.3 KB/sec ) Upload Speed: 353 kbps (44.1 KB/sec )

      Looks as though 1492 is a winner.

      Very odd - as I said, something else is happening here as it is easy to demonstrate that the right MTU for the Sky network is 1500 (at least in regard to packet fragmentation).

      Are you Vista by any chance - and have you run TCPOptimizer?

      Neggy on Vista. (Whoops, slipped into the old CB lingo there - that dates me!). No, I'm running XP Pro on a 2.66 Ghz P4 with 1 Gb of memory. Yes I did try TCP Optimiser but it makes the connection slower.

      What I don't understand though, Sky's default MTU is set to 1500 and the default (factory) settings include UPnP switched on. Yet this forum has discovered that the UPnP makes the router less reliable, with the advise that we should switch it off - isn't it just possible that the default 1500 MTU is wrong too? I mean it's pretty obvious that whoever programmed the router for Sky originally hadn't a clue what he/she was doing, so is this another example?

      Perhaps a few of you could try switching to 1492 or even lower (AOL reccomends 1400 I believe) and testing the actual download speeds.

      I suggested Norton d/ls, but I also reguarly d/l new Linux distros which are upwards of 600 Mb and whilst using Firefox so I can visually see the d/l speeds.

      No I don't think so - test it yourself. Open up TCPOptimizer and run the MTU test (though your comment about it making your connection slower makes me wonder whether you've messed up the settings). If you don't believe that test run this one. You should see Max packet sent/recieved (MTU) as 1500. That tester may also reveal any errors in your TCPOptimizer settings.

      1500 is the standard MTU for a PPPoA connection and Sky is PPPoA.

      1492 is the standard for a PPPoE connection. 1400 is a non standard AOL PPPoE setting.

      Re: Important Discovery!

      Just checked it again with TCP Organiser set to the PPOE 1492 and the router page also set to 1492. Here are my results from the Namesco test:

      Download Speed: 6078 kbps (759.8 KB/sec ) Upload Speed: 347 kbps (43.4 KB/sec )

      I may not be able to convince others but on my setup the PPOE settings make the down loads faster. Also my router doesn't freeze so often with these settings.

      I had BT in to check all my wiring and it's all fault free. Cannot run a test from the master socket because it's buried in the loft (it took the BT engineer 2 hours to find it!) and I haven't got a long enough extension cable to where my computer is.

      Actually, at the end of my 12 month contract I will move to a more reliable supplier, if there is one!

      Not with up 8Mb with a 40 GB download for 5 there isn't. Anything comparable will cost you 4 times that.

      Even at that cost, a reliable connection that doesn't keep freezing at random times, it might be worth it. As it is I've torn out most of my hair.
