Home networks now connect laptops, phones, smart TVs, cameras, and appliances. A weak router configuration puts all of them at risk.
1. Change default admin credentials
Routers ship with public default usernames and passwords. Change both before anything else connects to the network.
2. Use WPA3 or WPA2 encryption
Avoid open or WEP networks. Use a strong Wi-Fi password and disable WPS if you do not need it.
3. Update router firmware
Manufacturers patch serious vulnerabilities through firmware updates. Check for updates quarterly or enable automatic updates if supported.
4. Create a guest network
Isolate visitors and IoT devices on a separate SSID so a compromised gadget cannot reach your primary computers.
5. Disable remote management
Unless you specifically need remote admin access, turn it off to reduce exposure to internet-wide scanning and brute-force attacks.
