Just been round to my dad's and his internet is rather slow. I did a speed test and it came out at 3 Mbps. Not too bad, he lives a mile or so from the exchange.
But his ping time was over 500ms! It's making web browsing slow in some cases and he's about to start using a webcam so I guess that's going to be rubbish with a half second delay!
Any idea on how to fix it?
