I have a TiBook who's wireless reception is really starting to get annoying (a common problem I know, but for some reason it's worse recently). It seems that wireless PC Cards really aren't that expensive, plus since I have an Airport Extreme base station, it seems I could make use of the 802.11g over the TiBooks built in Airport card. Rather than just try the mods to attach an external antenna to the TiBook, a new card seems easier... Any recommendations on a Card that works well or is well supported by OS X? I don't use the card slot really for anything else, and I don't transport the TiBook enough to be worried too much about the antenna thing sticking out the side. Thanks!
