How to Secure Your Home Wi-Fi Router: 10 Settings to Change
Originally published on CodingCush . Your home router is the front door of your whole network. Every phone, laptop, smart TV and camera in your house talks to the internet through it.

Your home Wi-Fi router serves as the main entry point for your entire network. Most routers ship with default settings, including an admin password that can be found in the manual. Cybercriminals are constantly scanning for unsecured routers using automated tools. However, securing your router only takes about 20 minutes and costs nothing. Follow these 10 steps to protect your network.
1. Change the router's admin password. The admin login controls every aspect of the router's settings. Create a strong, unique password and store it in a password manager.
2. Update the firmware. Firmware is the router's operating system. Check for updates regularly and enable automatic updates if available. If the router is too old for updates, consider replacing it.
3. Use WPA3 or WPA2 for wireless security. Avoid using WEP or an open network, as they are easily cracked. WPA3 is the most secure option, followed by WPA2-AES.
4. Set a strong Wi-Fi password. Create a long passphrase of random words that are easy for you to remember but difficult for others to guess. Treat it like a strong password for other accounts.
5. Change the network name (SSID). Avoid using the router model or your name in the SSID. Choose a neutral, generic name to avoid giving attackers clues.
6. Turn off WPS. The push-button WPS feature is convenient but weak, and its PIN can be easily brute-forced. Disable it to enhance security.
7. Disable remote management. Remote management allows the admin panel to be accessed from the internet, opening up potential attack vectors. Turn it off, along with any WAN access.
8. Set up a guest network. Use a separate network for visitors, smart gadgets, and other devices. This prevents compromised devices from accessing your primary network and sensitive data.
9. Check the list of connected devices. Review the list of devices connected to your network. If you see unauthorized devices, change your Wi-Fi password immediately.
10. Restart the router periodically. Restarting the router once a month helps clear malware that resides only in memory and keeps the router functioning smoothly.
When accessing your router's settings, avoid using UPnP and be cautious of DNS settings. Some infections only change the DNS, redirecting you to fake websites. Ensure your DNS is set to automatic or to a resolver you choose yourself.
