I am having some issues with my macbook's wireless. I was wondering if there was any good way to determine if it is my airport card that is acting up or if it is just a bad antenna connection (without opening it up... preferably). My girlfriend has the same macbook as myself and she can get 4X as good of reception than I can. I can be sitting 6ft away from the router and still only be getting 2 bars (and might loose them intermittently). I've tried using KisMAC to see if there was any interference from other wi-fi signals, but I don't think that is the issue. Thoughts? Cheers, This community is great.
