Always use the strongest encryption protocols available, such as WPA3. If your router doesn’t support WPA3, opt for WPA2. Avoid using the outdated WEP as it is easily hackable.
Change Default Credentials
Routers often come with default usernames and passwords. Make sure to change these to something more secure to prevent unauthorized access to your router settings.
Enable Network Encryption
Encryption converts your data into a secure format. Ensure that network encryption is enabled in your router settings to protect the data transmitted through your network.
Disable WPS (Wi-Fi Protected Setup)
While WPS may seem convenient for connecting devices, it can also pose a security threat. Disable this feature to avoid potential vulnerabilities.
Monitor Connected Devices
Regularly check the list of devices connected to your network. If you see unfamiliar devices, it may indicate that someone is accessing your network without authorization. Change your password if you suspect a breach.
Troubleshooting Common Issues
If you face difficulties when changing your Wi-Fi security key or reconnecting devices, check the following:
Device Not Connecting
- Check Password Entry: Ensure that you’ve entered the correct new password, with the right capitalization and characters.
- Restart the Device: Sometimes a simple restart can clear connection issues.
Accessing the Admin Panel Fails
- Double Check IP Address: Ensure you have the correct IP address for your router.
- Reset the Router: If you cannot log in due to forgotten credentials, reset the router to factory settings. Note that this will erase all customized settings.
