    Intel AC 7260 - Channel bonding (40 MHz) on 2.4GHz with infrastructure mode

    Mat6674

      I'm using the AC 7260 (7260HMW) adapter in infrastructure mode on Windows 2012 R2. The AP has been created with the Windows hosted network facility. The problem is that the adapter does not use 2.4 GHz 802.11n channel bonding (40 MHz). What I'm expecting is that channel 11+7 are used with a maximum of speed of 300 Mbit/s. However the network shows up in the network analyzer running on channel 11 with a maximum speed of 144.4 Mbit/s. There are no other BSS (APs, STAs) in the environment which could influence the channel selection.
