I don't think the Linksys BEFSR41 v2 can do the full 10meg, but the v3 does. Also the speed test you did seems to think you're on a 1meg tier... "Ideally, you should get a result of around 1000 Kb/s (higher is better)" ...and your results say that you're getting around the 4000-5000 Kb/s, about half of what you could/should get on a 10meg con.
