Step 1: Physical checking


1. Check the ONU fiber optic signal (Figure1). If you see a red light on it then turn it off by pushing the black power button, wait 5 seconds, and turn it back on. If the light is still red then the fiber connection may be cut off. Let our helpdesk know by following the instructions at the bottom of this document.

2. If your ONU is hot then restart it by following the instructions in part 1.


3.  If your internet is still down and there is no red light on your ONU then check the network cable from the ONU to your wireless router (Figure 2). Make sure it is not loose and it is properly connected.
