Yeah, I thought it was strange too and I just figured it was an ISP problem.
The speed that I gave you are from a hardwire connection from the router, I get a relatively similar download speed on a wireless connection. Sometimes I get speeds of around 800 down depending on day. I've also tried different ports with no significant change.
I am connected via PPPoE through the router and connected to an older model DSL "dumb" modem (it is strictly a connection point only, no routing capabilities) The router handles DHCP for my network.
