Hello Community & Intel.
I recently upgraded my networking to AC. Currently 50MB/s+ connection from my ISP. I am staying connected but coming up on several short comings from one or both devices. I have read the discussion board but haven not found any solutions. If anyone could help, I would appreciate it.
ISSUES: 1.) Intel card is not showing up as Bluetooth capable. In Advanced settings on the card it shows as enabled but nothing. I have installed latest BT drivers and Pro Tools but nothing.
2.) The major issue here is I am not getting AC quality connection. Windows 7 doesn't show it as an "AC" connection but a "N" for radio type. Now from reading the board, I believe this is a simple lack of Windows 7 update. My connection speed is only 195 MB/s at the moment and range from 117-265MB/s nothing even close to the advertised AC ranges. I have tried so much with no luck.
I have tried so many suggestion this board has come up with for similar problems with no luck. I will list a bit up info commonly asked for on these boards to perhaps help. Thank you in advance.

It's definitely running AC which is why Windows is showing 866.7 as maximum rate. The only thing that Windows 7 netsh isn't showing is the 802.11ac protocol due to not being updated by lazy Microsoft so you won't see the 802.11ac under radio types.
Keep in mind that even though the speed is less than 300 Mbps, it is still 802.11ac WiFi!
Here's the evidence:
Your ProSet screenshot shows 175.5 Mbps! No 2 stream 802.11n PHY rate will EVER show 175.5 Mbps because it only exist on 3 streams and 20 MHz channel width on 802.11n mode. Intel 7260AC is a 2 stream card so it'll never get that rate under 802.11n
On 802.11ac mode, Intel 7260 can establish that 175.5 Mbps PHY rate with 1 stream, 16-QAM, 3/4 coding rate, VHT80, and long GI. When instability to connect at higher PHY rates is apparent, WiFi drivers negotiate at lower speed through common means such as decreasing coding rate, using a slower modulation type, using long GI, decreasing channel width and finally disabling MIMO.
Having explained that, you can increase your speed to 866.7 Mbps (achieved using 2 stream, 256-QAM, 5/6 coding rate, VHT80, short GI) by moving to the same room as the router (line of sight range), setting your router to use 80MHz only with WPA2-Personal AES encryption only, WMM APSD enabled and finally, selecting a channel as wide as 12 channels (i.e. 36 - 48 and 149 - 161) that are free from co-channel and overlapping channel interference.

As always you are very helpful. I appreciate the response.
Any idea on the lack of Bluetooth?

It could be that the hardware or software switch is off.
However, if the mini pcie slot doesn't have a USB lane, you'll never get bluetooth due to it utilizing USB. Thus people connect their cards to WWAN slot which usually has USB lane but they modify Pin # 51 to prevent the BIOS from disabling it: http://forum.thinkpads.com/viewtopic.php?f=30&t=113329 forum.thinkpads.com • View topic - Half-mini PCIe Intel Dual AC-7260 - No AC and Bluetooth
