Office Wi-Fi segmentation for a small team
Use a guest or VLAN feature so visitors and plugs are not on the same network as staff computers. If the router cannot do that, do not invent a second router maze.
Three groups
Staff computers, guest phones, and unattended gadgets such as printers or plugs should not share one flat password if you can avoid it. Many small routers do this with a guest network. Some business routers do it with VLANs. Pick the feature your hardware actually has and test it.
Who this is for
A few employees in one room. A company with compliance duties needs a professional design.
Plan
- Start with guest Wi-Fi for visitors.
- Put the printer where staff can reach it and guests cannot, if the router allows that exception. If it cannot, do not publish the printer on the guest name.
- Write the password store location. A segmentation plan with the password on a whiteboard is theater.
- Fold the decision into the workspace checklist.
Limits
Segmentation is not a backup and not antivirus. It only limits who shares a broadcast domain when it is configured correctly.
Questions readers ask
Is a second router the same as segmentation?
Usually it creates a double network that is harder to troubleshoot. Prefer the guest or VLAN tools in one gateway, or hire someone if you have outgrown it.
