Hi everyone, I'm new to this board and new to mac. I purchased a macbook a while ago. I live in a house, and the wireless signal from my linksys gateway seems to be strong throughout the house when I use my thinkpad, but not so with my mac. Is it possible that the internal wireless card in my pc has a better antennae than my mac? If not, can I take my macbook into a genius bar to have the internal card checked out? If so, is there an external airport card I can plug in to boost the signal? Thanks!
