Wifi

I think it was a smart move to move to the dongle. While the T1+ we have does not get too warm, the MAG boxes we have get really really hot. I attribute that heat to the internal WIFI. The T2 is nice and cool..
 
There are also 3 tiers of Wi-Fi antenna. W1 2.4 only, W2 (which ships with NA z7+) dual band rated for 600 mbps, and w3 dual band rated for 1200 mbps. My w2 antenna from my formuler worked perfectly fine on T2. Would like to get my hands on a w3 now for comparison.
