To troubleshoot an issue with your computer staying connected to Wi-Fi, the following steps could help:

1. Check your network adapter is enabled and that the device drivers are updated to the latest version.
2. Check if your router is broadcasting on the appropriate Wi-Fi channel.
3. Verify that your password is correct – it should match the case of the router’s configured passkey.
4. Try disabling the firewall on your computer, router and/or other relevant devices.
5. Check if the distance between the router and the computer is greater than the recommended range.
6. Use a VPN to protect your Wi-Fi connection and enhance security.
