Imagine your WiFi connection as a series of delivery trucks delivering data packets to your devices. With 802.11ac WiFi, each delivery truck or “packet” could only deliver one parcel to one device at a time. But with OFDMA, each truck can deliver multiple parcels to multiple devices simultaneously improvement in efficiency works for both uploads and downloads. | Operating Systems Microsoft Windows 10, 64-bit (even XP), Google Chrome OS, Linux, there's also Linux support, enabled in the Linux 5.1 kernel (if you have any existing Wifi or Bluetooth drivers; it may cause an error in the device manager and the newly installed card may not operate properly. please disabled the old driver in the Device Manager) A USB header is required from the motherboard for Bluetooth functionality but a USB 2.0 Male A port is provided on the card.
