Here are several steps to secure your wireless network:

1. Change your router’s Default Administrative Password & username: Default usernames and passwords may be easily found online. It’s best to change them for security purposes.
2. Enable Network Encryption: Wireless network encryption provides an extra layer of security. It prevents unauthorized access to your wireless network – be sure to set yours to WPA2 for optimal security.
3. Update your router’s firmware: Check the manufacturer’s website and see if your router has any available updates. It helps secure any security vulnerabilities that were previously unknown.
4. Disable remote management & guest networks: These features are unnecessary, and can open up your router to nefarious activity.
5. Keep your router in a secure location: Put your router somewhere not easily accessible – avoid open or exposed areas to prevent tampering or theft.
