Are the antennas suitable for 5GHz? What about signal strength? On the MAC it might be useful to install a WiFi scanner which will tell you all about signal strength. There is a free program called "Wifi Scanner" in the AppleStore. It is very useful. I can't help with the COMPEX miniPCI 'cause I got another brand on my Alix 2D13. But I realized that signal strength with 5GHz can be significantly lower than with 2.4GHz using antennas which are meant to work on both bands.
