Hi, I'm John! I will help you with this.
When the Wi-Fi disappears, do you notice any error code in Device Manager for the Intel wireless adapter? If possible please capture a screenshot and attach it in your next response.
Also, have you tried completely uninstalling the Wi-Fi driver to let Windows reinstall it?
> Right-click the Start button and select Device Manager.
> Expand Network adapters and find your Wi-Fi adapter.
> Right-click it and select Uninstall device, then check the box for Delete the driver software for this device (if available).
> Click Uninstall, then restart your laptop. Windows should automatically reinstall the driver.
If issue still persists let me know, and we’ll dig further if needed.
