OK, I'm getting sick and tired of Apple's crappy 802.11n drivers. I'm one room away from my WAP, but my signal strength is around 60% and the signal keeps dropping intermittently and often takes forever to reconnect. My brother's Acer laptop (which is 802.11g, btw, not n) has absolutely no problems. I want to try using an external (USB or ExpressCard) card...does anyone have any recommendations?
