If there is no apparent packet loss (or very little packet loss) when doing ping tests, you might find you have a similar problem to me in that small packets (eg. those of default ping size) get through with much less packet loss than larger packets.

Try opening up a command prompt window (if you're using Windows) and do this:

ping -L 2000 -N 20 www.bbc.co.uk

(ie. ping www.bbc.co.uk with 2000 bytes 20 times)

If I do that test, I get 50% packet loss.

If I ping the same site with the default size of 32 bytes, I get little or no loss.
