In my previous posting I mentioned Qualcomm Atheros QCA6174A-5 based half-size MiniPCI cards with 2×2 IPEX MHF4 antenna connectors as an 802.11ac wave2 upgrade for the ASUS UX31A. There are finally similar cards with 2×2 U.FL connectors available that make this upgrade an option for notebooks like my ASUS UX32LN or any newer ones.
The original card in my ASUS UX32LN Zenbook was an Azurewave AW-NB110H with 802.11a/b/g/n capabilities. I haved decided to go for the Bointec DPE109A. The card is very mature, works well under Linux and Windows 10 and I recommend it to anyone who wants to upgrade his notebook with a 802.11ac Wave 2 card and has a half-size miniPCI slot with 2 U.FL antenna connectors. It works well with an TP-Link Archer C2600 router and a Microsoft Bluetooth Mobile Mouse 3600 (BT 4.0).
Users that already have a 802.11ac card in their notebook should consider to purchase only if they are able to benefit from the Wave 2 features like MU-MIMO (e.g. they use a 802.11ac Wave 2 router).
