mITX build with Gigabyte z97n-WIFI with onboard intel dual band AC 7260 in an mPCIe slot. I also have a netgear R7000 router. I can't get the thing to connect via 5GHz AC, only via 5GHz N. Speeds hover around 27Mbs as well. I've turned on WMM in the intel client, as well as thoroughput booster. Did nothing. I've updated to the latest Windows 7 64 Proset drivers for wifi and Bluetooth. Still nothing. Any pointers?
Cheers,
Alex
