I have a PC running XP and a new laptop running Vista.
I have a wirless connection from both to a router. I have both computers recognising a home network and both connect to the internet via this network. Neither computer seems to see the other and both say they are the only one connected. If I turn off firewall on both still the same. I want to establish file sharing between them. How do I do it? What have I got wrong? Can anyone help?

This is a repost:

Refer to How to configure file sharing in Windows XP and Windows Vista File and Print Sharing.

Set your laptop running Vista to basic network sharing.
