Perform a power cycle, by unplugging your modem from the wall for a duration of 30 seconds. Sometimes your cable modem may require a restart.

Restarting your modem may fix some Internet connection issues, improve slow connections, and resolve frequent wireless issues.  Best way to reboot a modem, unplug its power and Ethernet wires.

2.Check the Coaxial cable

Make sure your coax connection is secure at both the modem and the coax outlet.

3.Check the Ethernet cable

Check to determine if the Ethernet connections at the modem and the Ethernet port on your device are secure

If the first three methods do not work and your modem is not damaged in any way, try a factory reset.

Factory Reset

When performing a factory reset, on a CODA-4680 returns to default settings, losing all user-configured settings and returning to its initial configuration state.

Method Two

Using a pin or pencil tip, press and hold the RESET button at the back of the modem for at least 30 seconds, it will take about 5 to 10 minutes for the CODA-4680 to reboot its self.

Factory Rest Button

Once the modem has rebooted its self which will take 5 to 10 minutes, If using wifi connect a device to the modem's EasyConnect Wi-Fi network. The EasyConnect Wi-Fi network only connects your device to the modem, it will not connect your device to the internet. The EasyConnect Wi-Fi network name and password is specific to your modem, and can be found on the label on the back of the modem. It takes the form of:

Default Wi-Fi Network: CODAXXXXX-EasyConnect (XXXXX is a series of numbers)

Default key: ZZZZZZZXXXXX (a series of numbers)

• Open up a web browser on the device you connected to the modem, and browse to any website.
• The Hitron EasyConnect Quick Setup screen should automatically load in your web browser. If it does not, enter 192.168.0.1 in your web browser's URL bar to load the Hitron EasyConnect Quick Setup manually.

Troubleshooting Wi-Fi

Most problems with Wi-Fi are a result of interference from other wireless or electronic devices, or signal strength problems (e.g., due to obstructions or distance).

Signal Strength problems

If you have a strong, solid signal in some parts of your home but not in others, then obstructions or distance could be playing a role.

Large appliances, such as refrigerators, can block Wi-Fi signals if the appliance is between your device and the modem. This can sometimes be resolved easily by moving you and/or your device from one part of the room to another. If your home is large and you are just running out of Wi-Fi range, then a Wi-Fi mesh home system or Wifi extenders  may be required. These can be purchased from NCF, and are placed around your home to extend the Wi-Fi range to other areas.
