  4. Check for loose cables: see image
    1. Check the coaxial cable.
    2. Check the Ethernet cable.
  5. Plug back in the modem.
  6. Plug back in the router, if you're using a router.
  7. Wait two minutes for the modem to initialize its connection.
  8. Turn on the computer.
  9. Open your web browser. Then try to open a reliable web page, such as www.google.com.

Still experiencing Internet connection problems? In some cases, refreshing your computer's Internet signal may help. Proceed to Fix #4.

Fix #4
Refresh your computer's Internet signal (IP address)

When your computer connects to the Internet, it is assigned an Internet Protocol address (IP address), usually a different address each time you connect. If you're experiencing slow or no signal, the problem may be resolved by refreshing your computer's IP address.

If you are still experiencing connection problems, contact us and ask to speak with a technical support representative.
