Al Cellier said : Earlier this year I upgraded my mid-2006 Mac Mini (Core Duo) with an (Macbook Original Wireless WIFI Card 802.11n AR5BXB72 - Atheros) Airport Extreme Card to get N-WiFi. That works fine in Leopard 10.5.8; but in 10.6.4 & 10.6.5, I can't get connected to my router. Is a new driver needed for 10.6 ? Network Utility / Info Tab / Network Interface (en1) reports "Model: Wireless Network Adapter," as (802.11a/b/g/n). As an aside, the Bluetooth seems much flakier now than with the original card.
The update, as of July 21, 2011 has that now that I have installed 3 antennas onto the WiFi card instead of just one, and now the Mini works great in Snow Leopard 10.6.8 !!!
We are getting full 300Mbps status on the n protocol.
No added drivers or tweaking, just the antennas and the system update (system update alone was not enough).
