- the router is powered on (lights should be on);
- there is a green or red light showing for the port where the antenna is connected;
- if you have a black PoE injector box, it’s also plugged in and switched on (usually there is a small white light on it);
- all of the cables are properly seated.
If all else fails, switch the router power off at the wall for 30 seconds and then switch back on.
If your connection is via a repeater on another property, check that it is on; this could be on a neighbour who has switched things off while they are on holiday for instance!
Please remember that if you host a repeater that serves other properties you should not switch off your electricity supply as it will stop their connection!
