If you are looking for an Altheros based card that has the best reception plus Mac compatibility I would suggest the 3Com 3CRPAG175. It has an antenna that retracts (which is also a switch that turns the card on when extended and off when pushed in). If you get this card you can then go to the 3Com web site and download Mac drivers that install a panel in the System Preferences which controls the card and supplies information and diagnostics. If you use a different Atheros PCMCIA card, you have to download (and pay for) Orangeware’s drivers to make it Mac compatible. I tend to use this card in the setting you mention because of its compact size and the excellent antenna system. You can also use a Broadcom based card (same as Airport) and forget about 3rd party drivers. One thing to keep in mind is that amost all Wireless routers in use these days use the Altheros chipset, so you can use the maximum setting on the card and get better speeds then you can with Airport. jg On 4-Oct-05, at 10:31 PM, Josh Zhixel wrote: > Does anyone have any recommendations for a decent 802.11g card > that'll 'just work' on OS X 10.4?
