One of two computers can't access network

Archived from groups: microsoft.public.windows.networking.wireless (More info?)

Answering my own post, Toshiba is fnally seeing HP - at least for the moment!

Probably what worked was resetting the TCP/IP, using the NetShell utility,
as explained in Microsoft KB 299357.

It is also possible, but I would guess less likely, that what helped was
simply going to Network Connections/rtclick on the relevant connection
icon/Properties/Wireless Networks/and then under Preferred Networks: (a)
removing "MSHome" which automatically reinstalls when the Network Setup
Wizard is rerun or (b) still less likely, clicking on Properties of MSHome
and disabling Data Encryption.
