2Wait, then modem first
Wait 30 seconds. Plug in the modem first and wait until its lights are steady (1–2 minutes).
3Then the router
Plug in the router and wait another 2 minutes.
4Read the lights
A red or blinking 'Internet' light usually means a provider or line issue. Check the cables are firmly in.
5Fix a single device
If only one device fails: turn WiFi off and on, 'forget' the network and rejoin, then restart the device.
