I just purchased an Intel AC 7260 (7260.hmwg) for a desktop system, a Shuttle XH61V. I installed the Intel drivers and software utility. When I try to connect to my home WIFI network, or any network, I get a Windows message saying no available networks. I know there are many networks in the area. The Intel wireless diagnostic software also says there are no available networks. The drivers appeared to install correctly and I see no conflicts with Device Manager.
I don't know if this is a deal breaker, but I don't have the adapter connected to any type of antenna. Should I buy an internal antenna, like the ones used for laptops ?
