Why guest Wi-Fi and staff Wi-Fi should be separate

The problem with one network

On a single shared network, every device can see every other device. A visitor’s laptop, infected without their knowledge, sits on the same network as your file server, printers, cameras and card terminals. The Wi-Fi password also tends to end up on a sign at reception, and stays the same for years.

What separate networks give you

• Guest Wi-Fi reaches the internet and nothing else. Guests cannot see your devices, or each other’s.
• Staff Wi-Fi reaches business systems, using a password or, better, staff members’ own sign-ins.
• Device networks for printers, cameras, door controllers and other equipment that does not need to reach everything.

Fair sharing

Guest networks can also be limited, so one person streaming video does not slow down your staff or your payment terminals. In hotels, venues and multi-tenant buildings this matters a great deal.

What to check

• Can a visitor on your Wi-Fi see your printers or shared folders?
• When did your staff Wi-Fi password last change, and who knows it?
• Does guest traffic get in the way of business traffic at busy times?
