I have been running this laptop for about a year and haven't found another wireless network around my house in all that time. the microwave and the cordless phone may be a problem but I don't know if they were in use at the time.
I'm not sure what I have in my windows laptop because it is built right in but I have got an ADMTEK 8211 chipset on my wireless card in my desktop. both computers are setup as ad-hoc.
here is the output of iwconfig
lo no wireless extensions.

for the xp box signal strength is excellent.
When I ping from the xp box I get a reply from the liunx box ip address.
As soon as I turned off my firewall on the windows box I started receiving replies to pings on my linux box and the network worked for about five minuets. Then windows dropped the connection and said I don't have permissions to view my network when I tried getting back on. Linux starts saying host is unreachable and windows starts saying the request timed out when I try pinging again.
