Can you check that when you plug the laptop in to the router it auto-negotiates the correct wire speed? If you are XP just left click on the network icon in the system tray.

You should be connected at 100mb full duplex to the router. If the laptop has gigabit ethernet, make sure jumbo frames is disabled. Also check the MTU is not too high.

If the router has the facility, check that it is connected to the modem at the right speed too (again, 100mb full duplex).

If you have two computers, you can connect one to the WAN side and one to the LAN side of the router and try transferring files or just using something like iperf to check the transfer speed.

The router you have should be capable of 70, maybe 80mb with a very low number of connections. With P2P and 500+ connections it might just hit 50mb. Probably the best bet for 50meg would be to get a Buffalo router and run Tomato on it. Buffalo routers can hit 98mb under realistic conditions, as they are design for use on Japanese 100/100 fibre. I have two and can confirm they work as advertised.
