    I have the same problem after a recent update. I use to be able to connect to 5GHZ network.

    Following your instruction, i found the ‘band’ option is missing under 802.11ac property. Only Bandwidth Capability: 11a:20/40;11bg:20MHz

    Tried to update the drive, but showes it’s the best ver.

    any suggestion?

    thank you
