Having troubles? Here's some first aid. 



  • Have you paid your bill?

  • Is everything plugged in and turned on? 

Look for lights on your optical network unit or K/Fiber ONU (the small white box with one power, one fiber, and one ethernet cable attached) and on your router. If they’re out, check if a power plug is dislodged from the electric outlet. Is a power strip switched off?

If the computer says the network cable is unplugged, make sure the ethernet (network) cable is plugged into the K/Fiber ONU and the computer or a router.

  • Is your router locked up?

It is not uncommon to have a good connection between your wireless router and your computing devices yet have no connection to the internet. This is because the router has lost its connection to our network device—the K/Fiber ONU. Solution? Reboot the router. Please DO NOT USE THE RESET BUTTON! Unplug the power to the router; count to ten; and plug it back in. Wait two minutes. If this fails, try the next suggestion below.

  • Is your K/Fiber ONU locked up?

More rarely, our K/Fiber ONU (the small white box with one power, one fiber, and one ethernet cable attached) may lose its connection to our network. This time, reboot both the K/Fiber ONU and the router. Unplug the power to the K/Fiber ONU. Count to ten, and plug it back in. Unplug the power to your router. Wait two minutes before plugging it back in. Once again, wait two minutes before trying to get online. Meanwhile, you can reboot your computer by powering all the way down and letting it sit for 30 seconds before powering it back up.

  • Windows computer: Has networking been disabled? 

Check for two computers in lower right corner. If they are there, is there an X through them? Right-click the icon, and then select Enable. If there are no computer symbols, go to Start>Settings>Control Panel>Network Connections, right-click on Local Area Connection, and then select Enable.

If the computer is a laptop, is there a keyboard button to enable/disable wireless access?

  • Macintosh computer: Is WiFi turned on?

Go to the WiFi icon in the menubar or to System Preferences>Network to Turn WiFi On.
