Wireless network cards

[Bryan Berch <dfbsd@xxxxxxxxxxxxx>]

I want to get a wireless network set-up in my house using my gateway
box.  Can any one give me a good choice in a wireless network card for
my desktop box or is there a better way to do it?  

If the network card route is fine, can there be an antenna located in a
central location in the house using a cable from the network card and to
the antenna?

I'm new to wireless and any suggestions appreciated.
