Here are some tips to help you secure your Wi-Fi network:

1. Change the default name of your router and Wi-Fi networks.
2. Create a strong password to protect your network. Avoid using common words, dictionary words, or personal information.
3. Encrypt your network connection. Use the WPA security protocol.
4. Set up a guest network for your visitors.
5. Disable Remote Management so only people you trust can access and manage your router.
6. Update the router's firmware regularly.
