Cantenna/USB Dongle WiFi Fun!
I just ordered up a D-Link USB 802.11b dongle. It should work great with a homemade antenna or a cantenna (link1, link2). It will be cheaper and less work than your typical cantenna/pcmcia combo: no coax hardware, no hacking the pcmcia card. There should be little signal loss since the dongle will be directly in the can and no lossy coax cable-- just get a can and make an adjustable sliding slot for fine tuning. The D-Link is 40mW, which seems to be a standard power. It will be a nice supplement to my laptop since there is little I can do with its built-in wireless. Stay linked as I get the shipment and work on the cantenna.
