I bought the card for my Acer V3 571G because the built-in Atheros chip not so good to me my Speedport W503V was clear. It always came back to disconnections or collapse the data rate. Before installing you should uninstall the drivers of old wireless chips in Device Manager. The installation of the chip was super easy. Disconnect the two antenna cables from the old card, retaining screw unscrew, remove old card, new card in, tighten the screw, antenna cable in, finished. Drivers can be found on the Intel website that are not supplied. Just the name of the map on Google enter, then takes you directly to the product page where there is the driver and the recommended settings for the card. The card was detected right after installation and can be switched using the hotkey command on and off as the old chip. The difference from the old wireless card is enormous. Has had no more disconnections. In addition to the router delivers the card 10MB / s, more makes the 100Mbit / s switch is not with the router. One floor above the reinforced concrete ceiling are still's 4-5MB / s. On the other side of the house there are still 2-3MB / s. That's enough for video streaming and Co. Sure you go even faster with an appropriate router. Wireless Display and Bluetooth I do not use, so I can not comment. All in all a super card that I would buy again at any time.
