If 5 GHz Wi-Fi is not showing up in Windows 11 and Windows 10, it can be due to several factors related to hardware, software, or configuration settings. Here are the main causes:
Driver Issues: Even if your adapter supports 5 GHz, outdated or incorrect drivers might prevent it from recognizing 5 GHz networks. Ensuring you have the latest drivers installed is crucial.
Incorrect Wi-Fi Settings:
Band Selection: Your Wi-Fi adapter might be set to only connect to 2.4 GHz networks. This can happen if the adapter is configured to prioritize or exclusively use 2.4 GHz.
Router Configuration: The router itself may not be broadcasting a 5 GHz signal, or it might be configured to use a channel that your adapter cannot detect.
Solutions:
Check Hardware Compatibility: Verify that both your router and Wi-Fi adapter support 5 GHz.
Update Drivers: Ensure that your Wi-Fi adapter drivers are up to date.
Adjust Wi-Fi Settings: Check the band selection in the network adapter properties and ensure it is set to detect both 2.4 GHz and 5 GHz.
Check Router Settings: Ensure your router is configured to broadcast on the 5 GHz band and that it is using a compatible channel.
