Hello all....

My girlfriend and I have to travel for work rather extensively, and sometimes we're only in a given location a few weeks - makes getting dsl/cable rather unwieldy. I've taken to wardriving a bit with my G4 Powerbook, and have had some reasonable luck (using Kismac and MacStumbler). Checking email and mapquest from behind a gas station in Reno is pretty groovy....

Problem is, we're currently in a place with limited signal strength to a couple of open (non wep/non wap) networks. How can I improve this? Is there a way to easily add an external antenna to the G4? Or am I stuck going after an aironet card and adding an antenna to that?

I've also got an Airport Extreme with antenna port - anybody know if I can run Kismac through the Airport so I can get some gain off an external antenna?

Thanks for the help - you can see, I'm a relative newbie to this...but it's cool!
