REBOOT YOUR ROUTER
Verify your router has power. The router should have lights.
Check that the ethernet cable is plugged in securely to the ethernet port on the back of the router. On this particular router, the port is blue but that is not the case for all routers.
Most ethernet ports can be identified by the "E" symbol shown above the port.
Reboot the router. Physically unplug the power cable (shown above). Wait 10-15 seconds and plug back into power.
REBOOT EXTERIOR EQUIPMENT
The POE (power over ethernet), also referred to as "the brick". It provides power to the radio located on the outside of the building via the ethernet cable. It also connects the router to the radio to complete the internet connection.
Check that the brick is plugged into a working wall outlet. Identify and confirm the brick is receiving power by the light on top (it may be difficult to see in bright rooms). Confirm that the outlet has power, GFI-s or circuit breakers have not disrupted power to the outlet.
The brick has two ports. One is labeled POE and the other LAN.
The LAN port has a cable that runs to the back of the router as shown.
The POE port has a cable that runs to the exterior radio. This cable is typically run into the wall and the outside of the building.
It is critical these cables are plugged into the correct ports. Plugging into the wrong ports will result in loss of connection.
REMEMBER: LAN port to ROUTER
POE port to RADIO
Unplug the POE (the brick) power cable from the wall outlet (power strip or battery backup). Wait 20 seconds and plug back into the wall outlet (power source).
If you cannot access the wall outlet but you have access to the brick; unplug the POE cable from the brick, wait 20 seconds, plug back into the POE port (see below)
