so i guess you have 2 wireless cards, one on every station...
on the host, put these settings in TCP/iPV4:
DG:192.168.0.2 (other's pc ip)
and, on the client, put these:
DG:192.168.0.1 (other's pc ip)
Lookup your ip address, the one that connects you to the wired internet, and enter it in the Preferred DNS field, on client machine, so:
also, you have to share your wired connection and allow it to be used by other connections
