Plan the guest network
- Choose a name that identifies the business without revealing private details.
- Use a separate password and change it when needed.
- Decide whether customers need unlimited access or a reasonable speed limit.
Protect business devices
- Enable guest isolation or the setting that blocks access to the local network.
- Keep printers, point-of-sale devices, storage, and staff computers on the private network.
- Do not assume a different Wi-Fi name guarantees separation; verify the router setting.
Test from a customer device
- Confirm the guest device can browse the internet.
- Try reaching a local printer or router page and ensure access is blocked.
- Post the guest password where appropriate without exposing the private credentials.
Stop guessing when the problem keeps coming back
Ask for help if the router lacks guest isolation, customer devices can see business equipment, or several access points need consistent settings.
