• Poor Wi-Fi signal – If the Wi-Fi signal in your home is very weak, the host and remote PC will have difficulties in proper data exchange.

What can I do if Projecting to This PC keeps disconnecting on Windows 11?

Before trying the actual troubleshooting methods to solve frequent disconnect issues with the Projecting to This PC feature, do the following things:

• Update Windows to the latest version.
• Use a 5GHz Wi-Fi band if your router and PC support it.
• Make sure you are not using a metered connection. Disable it if necessary.
• If it is a laptop, make sure you are using high-performance mode.

After ensuring the above things, you can proceed to the methods featured below.

1. Update the network and display driver

1. Open the Start Menu.
2. Type Device Manager and press Enter.
3. Right-click on the Network driver and click on Update driver.

So, we suggest you use Outbyte Driver Updater. It can scan outdated and missing drivers and update or install them with just a single click. If configured, it also can do it automatically according to your own schedule.

Updating these drivers should solve the disconnecting problem with the Projecting to This PC feature. If not, follow the next methods.
