Guest Wi-Fi: why it is separate and how to share it

Most of the business networks we set up have at least two Wi-Fi networks: one for staff and company computers, and one for guests. This article explains why, and how to use the guest network well.

Why a separate network

Devices on the staff network can reach your shared drives, printers, server and business software. A visitor's laptop, a contractor's tablet or a customer's phone could be carrying malware without them knowing, and on the same network it could reach those systems. The guest network gives visitors internet access only. They can browse and check email, but they cannot see anything inside your business.

Who should use the guest network

Visitors, customers and contractors. Staff members' personal phones and tablets. Smart devices such as TVs, speakers, streaming sticks and smart thermostats, which are often poorly secured. If a device does not need to reach your printers or files, it belongs on guest Wi-Fi.

Sharing the password

The guest password can be shared more freely, for example on a small card at reception or a sign in the meeting room. Never share the staff Wi-Fi password with visitors. If it has been given out widely over time, ask us to change it; we will update the company devices for you.

Changing the guest password

For a business that has a lot of visitors, changing the guest password every few months is good practice. We can do this for you, or set up a simple sign-in page for guests if you prefer.

Something will not work on guest Wi-Fi

If a staff member needs to print from a personal device, or a new piece of equipment needs to talk to your systems, email hello@bitlogix.tech rather than moving it onto the staff network yourself. There is usually a safe way to allow just what is needed.
