    • If there's an outage, hang tight. We're working to get you back online.
    • If there's not an outage, go to step 2.
  2. Check each item until the antenna power supply light is green. Make sure the:
    • Antenna cable is securely attached at both ends with the outdoor antenna cable end being connected to the blue port on the antenna power supply, and the other end connected to the wall jack leading to the outdoor antenna.
    • Ethernet cable is securely connected with one end attached to the red router port of the antenna power supply, and the other end to the red gateway port.
    • Power cord to the antenna power supply is securely plugged in at both ends.
    • Antenna power supply switch is on and the power light is red—if it's not, confirm the outlet is working.
  3. If the antenna power supply light isn't green, turn the antenna power switch off. Then wait 10 seconds and turn it back on. If it's still not working, go to step 5.
  4. Press and release the red Reset button on the back of your gateway to restart it. This can take up to 10 minutes.
  5. Watch the broadband or service light. When you see a solid green light, close and reopen your browser.
