Verify that your modem cables are connected.

  • Coaxial cable - Verify that the coax is finger tight at the cable outlet on the wall and at the back of the modem.
  • Ethernet - You may see what resembles an oversized phone cord connecting your modem to a router or desktop computer. Cox recommends using at least a Category 5E (CAT5E) cable for all packages.
    • On the router, make sure the Ethernet cord connects to a port labeled Ethernet, IN, or WAN. If it's not there, then you'll need to move the cord to the right location.
    • If the Ethernet is connecting to a computer, make sure both ends of the Ethernet cord are connected securely.
