Compatibility and related parts
You need a free USB port and Windows 10 or 11, as those are the supported operating systems. To get Wi-Fi 6 speeds, your router must also support 802.11ax. Older routers still work through the adapter's a/b/g/n/ac support. If you are building a new desktop, use our PC builder to plan your connectivity.
