Windows 7 won't recognize XP PC in network

A Home network is a local area network used for communication between digital devices at home, usually personal computers. Homegroup is a feature that simplifies files sharing only between Windows 7 machines and do not communicate with XP/Vista computers. To change this, you need to change the networking system so that Windows XP Operating System can be used. Go to network and Sharing center in the Control panel and check if you have set up Home network in your active networks. Choose Work network to convert Homegroup to your Workgroup to enable sharing of and access to resources between Windows 7 and XP/Vista. You need to assign the same Workgroup name to both machines.


I had a Compaq computer running Windows XP - I used a Linksys WRT54G, Version 2 to network with my laptop, also running XP - everything worked fine. Two weeks ago I purchased a new HP P6230Y loaded with Windows 7. When I set up the computer I attached the router to the new computer. However, I can't get the new PC to recognize the old XP PC and I can't even go online with the XP. Do I need to somehow uninstall the Linksys info from the old PC? If so, how do I do that? Any help you can provide me with would be appreciated!


Did you set up Homegroup for networking in Windows 7?
Homegroup only works with Windows 7 computers and will not talk to your XP computer.
If so, you will need to change the networking system to one that XP can use.

On your Windows 7 computer:
  • Click the Start button at the bottom left of the screen.
  • Then go to the Control Panel and choose Network and Sharing Center.
  • Click the link under "view your active networks" (if you've set up a Homegroup, the link should say "home network").
  • In the next window choose "Work network": this will switch you from a Homegroup to a workgroup so your two computers can talk to each other.

Before you can network the computers, you must assign the same workgroup name to both of them and SHARE folders in Explorer.

The XP computer's internet problem is not related to the above. If your broadband modem is connected to the router and the router is connected to each computer, you should not have any problems. If you are using a wireless connection you may have changed the ID or keyword when you installed the Windows 7 computer.
