    While Wi-Fi 7 is backward compatible with previous generations, new Wi-Fi 7 features require PCs configured with Intel Wi-Fi 7 solutions, PC OEM enabling, operating system support, and use with appropriate Wi-Fi 7 routers/APs/gateways. 6 GHz Wi-Fi 7 may not be available in all regions. Performance varies by use, configuration, and other factors. For details on performance claims, learn more at https://edc.intel.com/content/www/us/en/products/performance/benchmarks/connectivity/.
    AI features may require software purchase, subscription, or enablement by a software or platform provider, or may have specific configuration or compatibility requirements.
