If the BIOS will not recognize the card checking for BIOS flash updates would be an option. Although first researching your laptops WiFi compatibility is always best.

    Tried the USB option, but didn’t get faster speeds. Does this mean something else needs to be updated in my 5-year-old laptop? when I enter ‘netsh wlan show drivers’ in CMD prompt window, I get 802.11n, 802.11g and 802.11b. Will upgrading my NIC change that?

      Is your USB 2.0 or 3.0? I had a USB-to-Gb Ethernet adapter that when plugged into a USB 2.0 as not nearly as fast as when plugged into a USB 3.0 port.
