Wireless connection should be fast but it is very slow

I am using a Samsung N210 with 2GB of memory in it and Windows 7 Starter.  When I use the wireless connection the "Connection Status" shows as 72Mbps, which is to be expected considering I am only a few feet from the router.  However, the speed is nothing like that in reality.  I tested the actual transfer speeds for the wired and wireless connections by copying a 238MB folder with 77 photos in it.  I copied it from the NAS device, where I store all my files, to the local disk of the netbook.  Here are the results:
Marvell Yukon 88E8040 Family PCI-E Fast Ethernet Controller
25s => 76Mbps
Realtek RTL8192E Wireless LAN 802.11n PCI-E NIC
660s => 3Mbps
What can I do about this?
I would be very grateful of any suggestions.
Thank you

Thanks. We'll let you know when a new response is added.

I usually use “iperf” for bandwidth measurements.

You can use wireshark to see if you are getting a lot retransmits.

do you have the latest drivers for your wireless interface on your laptop?

    you may have a fast connection, but is there are errors in the transmitted packets (interference, etc.) it can still take a long time to transfer

    The wireless speed is very slow. We have another laptop that works much better.
