How to Secure Your Business Wi-Fi (2026 Checklist)
Lock the basics
Use WPA3 (or WPA2 at minimum), a long unique passphrase, and change the router's default admin password. Update router firmware — old firmware is a common hole.
Separate your networks
Put guests and untrusted IoT devices on a separate guest network so they can't reach your business computers and files.
Keep it maintained
Review connected devices, disable WPS and remote admin, and rotate the passphrase when staff leave. IT Cares can set up and manage business-grade networking.
Action checklist
