I think (and will be corrected if I'm wrong!) that only web traffic goes through the proxy server. So your ping tests are making a direct connection between your computer and the server at the other end (without any proxying going on).

I thought that and did try lowering my MTU value to 300 bytes. Didn't seem to help very much :-(

My brother has an NTL broadband connection in his flat (he lives in London, same modem and connection speed as mine). I took my laptop and doing that same test with 2000 bytes to www.bbc.co.uk resulted in zero packet loss. My laptop is running XP Professional. So the fact is that in your area and my area, there is something wrong with the network that is causing this behaviour. It seems to me that the more data you send at once, the more chance there is that it won't get delivered.

Don't know whether any network experts out there can come up with a diagnosis or any ideas based on this information, or just tell me that I'm barking up the wrong tree altogether.
