This dual band wifi card, the Intel AC 7260HMW Mini PCI-E BT4.0, was easy to install and my Linux Mint laptop set it up automatically when I booted it up. No problems so far after 3 weeks of use. Both the 2 GHz and 5 GHz bands work well. Even though this card is recommended for an HP laptop, it works just fine in my Dell Mini Duo 1090.
