My laptop (asus x454l) is not recognizing the 5g WiFi that is working on my husband's laptop. When I checked with Asus, they said this laptop is only 2.4ghz compatible and I need an adapter to connect to both. Can anyone recommend which adapter will work (tech novice here ). The wifi card is Qualcomm atheros 956x if that helps. Don't want to blow a bomb on it but not end up with something that stops working in a month. Thanks!
