Disclaimer

†Maximum wireless signal rates are the physical rates derived from IEEE Standard 802.11 specifications. Actual wireless data throughput and wireless coverage, and number of connected devices are not guaranteed and will vary as a result of network conditions, AP limitations, and environmental factors, including building materials, obstacles, volume and density of traffic, and AP location. 
‡Use of Wi-Fi 7(802.11be), Wi-Fi 6(802.11ax), Wi-Fi 6E(802.11ax), and other features including MLO, 160 MHz Bandwidth, 4K-QAM, Multi-RUs, OFDMA, MU-MIMO, and BSS Color requires the AP and PC OS also to support the corresponding features. The MLO is still being developed on some Wi-Fi 7 models and will be supported in subsequent driver updates.
§Use of WPA3 requires APs also to support the corresponding feature.
△The number is based on testing conducted by the USB-IF and your computers are required to also support USB 3.0.
☆To ensure compatibility, you may need to update the adapter’s drivers after an OS update, you can find our latest drivers in the download center at
