Compatibility and related parts
Check that your computer runs Windows 10 or 11, the supported operating systems listed for this adapter, and that it has a free USB port. For the best results, pair it with a Wi-Fi 6 (802.11ax) router, though it also supports older 802.11a/b/g/n/ac networks. If you are planning a new system, the PC builder checks compatibility, and parts bought as a PC build get free assembly and testing. You can also compare internal options in Network & WiFi Cards or see other TP-Link products.
