I would also take a look at the packets when he is connected wirelessly, and wired, and see if you see a higher level of duplicate acks, or fast transmissions, which might spell issues with the physical media ( NIC, Cable, Port on the Wireless router, etc etc)

Can you add/replace the network card? You didn't say if it is a desktop or laptop? If it is a laptop, I'd test at a different location. Friend, co-worker or some other place. If a desktop, slap a cheap nic in and see what happens. From: Roger Wright [mailto:[email protected]] Sent: Monday, December 05, 2011 10:15 AM To: NT System Admin Issues Subject: Home Throughput Issue A colleague has a problem that is stumping us: He has broadband at home and when connecting wirelessly to his router his throughput is significantly slower than when using the Ethernet connection. Speedtest.net says he's getting in excess of 20Mbps down and 5Mbps up via a wireless connection, but with a wired connection to the router his reported speed drops to 5 down/1 up, and the difference is readily apparent when browsing. Connecting with a wired connection from another machine, however, doesn't not report a slower speed and closely matches the wireless speed. He's updated the drivers for the NIC, adjusted the speed and duplex settings, disabled the software firewall, tried other ports on the router, swapped cables, but cannot improved his throughput when using an Ethernet connection from this machine. It seems odd that his wireless connection would be noticeably faster than his Eethernet connection. Anything else he can check? Roger Wright ___ I just had my vision checked. My hindsight was 20/20.
