These are the problems I am encountering.

  • XP can access Windows 7, not the other way around (which is fine, because I don't need it the other way currently)

  • File transfer is too slow like 0.031 MB/s even though netperf and netCPS list around 8-9 MB/s.

I disabled firewall on both computers. Both are same workgroup. I left homegroup on Windows 7. Windows 7 sees the connection as unidentified network.

10.1.1.2 (XP) and 10.1.1.1 (Windows 7) Subnet mask 255.255.255.0 Default gateway and DNS are empty for both of them.

Both computer are connected to internet using wireless (using home network), and both of them are connected to each other using wire!

If anybody has any pointers, do let me know. I have no problem doing such setup with both computers being Windows 7. This time one of them is XP though, and that seems to be the problem.

I figured out the problem based on this thread which didn't have much to do with my own problem: http://social.technet.microsoft.com/Forums/en/w7itpronetworking/thread/7aadace2-8fc0-4c7b-8ffe-76e285d02c06

On windows 7, do the following: 

Control Panel --> Network and Sharing Center --> Change Adapter Settings --> right click the conection and select properties --> select Configure button --> goto Advanced tab --> look for Link Speed and Duplex --> change Auto Negotiate to 100 Mbps Full Duplex.

Firstly, I'd disable the wireless for an over-the-wire file transfer. This is simply to reduce probable problem sources.

Secondly, make sure you're using a crossover cable for your connection. You can buy these from some electronics stores, or make one yourself from an existing patch cable. Seek Wikipedia for more details.

It looks like you've got the rest of the configuration pretty much right - disabling firewalls and setting static IPs. During the file transfer, make sure the Windows 7 firewall is completely disabled for all networks (public & private). Best bet is to just shut down the service itself via services.msc. Don't forget to put your firewalls back up before you connect to the Internet again, and make sure the static IPs are on your ethernet ports and not the Wi-Fi.

Lastly, to further minimize other sources of performance interference, make sure you don't have any programs running except what is necessary for your file transfer.
