Guest Wi-Fi, IoT VLANs and smart-home safety
A flat full of plugs, cameras and speakers on the same LAN as your laptop is a soft target. Guest isolation and a separate IoT SSID cost nothing and remove most of the realistic risk.

Do this, in order
- Enable guest network with client isolation for visitors; keep the main SSID hidden from them.
- Put cameras/plugs on the 2.4 GHz IoT SSID and disable their cloud P2P if you do not use it.
- Change default camera passwords and update firmware; these are the usual entry point.
- For home offices, separate the work laptop onto its own SSID or VLAN.
- Turn off WPS on the router - it is a shortcut attackers use.
