THE DEVIL SUGGESTS
Map every device on your home network
Make a plain-English inventory of what is connected to your Wi-Fi and wired network. You may find old smart plugs, forgotten printers or devices with names that explain nothing.
Do it
- Log in to your router and view its connected-device list.
- Walk around the house identifying devices one by one.
- Rename recognisable devices in the router if it allows it.
- Record each device, room and connection type in a simple list.
- Investigate or remove anything you cannot identify.
What next?
Keep the useful notes, photograph the result if there is one, then go and find something else to do.
