I can connect on wifi with both 2.4 and 5 GHz. However signal strength is low when not within a few feet of the router. In the room where the NUC resides it gets about 4Mbps up and down with a Netgear R6300V1 AC router on the 5GHz freq. When I install the A6200 netgear USB 2.0 wireless ac adapter I receive about 100Mbps up and down in that room. The room is about 30 feet away. When the NUC and the 7260 are close to the router they get about 150Mbps. The USB AC adapter gets about 220Mbps. Lastly, when I check the properties on the 7260 card it is connected at 750Mbps when close to the router and its connected at 12Mbps when in the room 40 feet away. The USB AC adapter is connected at 866.5Mbps and 175Mbps when close or 40 feet away respectively.
I was asked to attach pictures with the last issue I had. I am attaching pictures with the 7260AC card installed and without it installed.
Please advise if I need to return either the NUC or the 7260AC card.
It does not look like a hardware integration issue as far as I can tell; I suppose the antennas are tightly fit and you have the latest http://www.intel.com/support/wireless/wtech/proset-ws/sb/CS-034041.htm Intel® Proset Wireless Software and AP's firmware version.
We are aware of similar issues that are expected to be fixed with an upcoming driver release. At this time I do not have an ETA but you may decide to wait if it is ok for you. I will post an update as soon as it becomes available.
