Compatibility and related parts
Check that your computer has a free USB port (a USB 3.0 port matches the adapter's interface) and that it runs a supported system: Windows 11/10/8.1/8/7 or Mac OS 10.15 and earlier. Your router should broadcast on 2.4 GHz or 5 GHz with WPA/WPA2 or WEP security. If you are putting together a new system, add it in our PC builder, which checks compatibility, and you get free assembly and testing when it is bought as part of a PC build. You can also compare it with other network and WiFi cards or browse more TP-Link products.
