I have a Macbook Pro CD 2.0 Ghz and I have to say the airport on it is pretty bad. In one of my classes a guy with a Macbook sits directly in front of me and he has almost full wifi signal (~4 bars), while I have nothing. I can sometimes see the network pop up but never get enough signal to connect to it. What I would like to get is a little USB wireless adapter and I might as well go for 802.11 N.. I would like one that has an external antenna like this Hawking HWUG1A, but it only supports G. Any suggestions for adapters with 802.11 N and an external antenna?
