Have you tried to use the test socket? Connect your hub to that and see if that makes any difference.
Just to prove the speedtest.net servers are overloaded and will give you different results!
First is Middlesbrough server with 44Mbps, the second is Newcastle server with 59 Mbps and the last is the result from speedof.me test site with 63Mbps. Use the test socket and check the speed on different servers with wireless and wired connection as well. If you still have issues I think a moderator will probably have a look at this for you.
Thanks all for posting. There's some usefull comments on this thread. We would always recommend using the wholesale speed tester on a wired connection but you'll also see your connection speed in your hub stats (thanks @licquorice @pippincp for pointing that out). Wireless will alwys show a descrepency in the speed but I take your point @matekaneve . I hope you've got the advice you were looking for @jaypeegolf .
