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.

Common fixes for Cable modems

If the modem's @ light is on but there is no internet, try power cycling it.

  • To perform a power cycle, unplug your modem from the wall for a duration of 30 seconds.

In the event that the @ light is off and the ⬇️ downstream light or ⬆️ upstream light is flashing try:

  • Disconnect and reconnect the coaxial cable at the back, making sure it is securely attached.

If the first two methods do not work, perform a factory reset.


Factory Reset

When you perform a factory reset, the CODA-4680 returns to default settings, losing all user-configured settings and returning the modem to its initial configuration state.

Method One

Your device will need to be connected to your modem by WiFi or an Ethernet cable plugged into one of the CODA-4680 modem's LAN ports.

  1. Open a web browser Chrome, Firefox of Safari and enter http://192.168.0.1 into the address bar then press enter.
  2. A login screen for the Hitron CODA-4680 will appear. The default username and password are case-sensitive.
    • Username: cusadmin
    • Password <the Wi-Fi network password that you configured in the Quick Setup>


CODA-4680-Login









Select Admin, choose Device Reset tab, and select the Factory Reset button.

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.
  • To begin the Quick Setup, select Let's Go

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.

Common Fixes For WiFi

Changing WiFi Channels on CODA-4680

Changing the wifi channels for 2.4 bandwidth

Connect to your modem using a wired Ethernet cable or join your Wireless network


2.4 Bandwidth

Step 1

Wifi channels

Login to the modem using a web Interface

  • Enter http://192.168.0.1 into the address bar in your web browser Chrome, Firefox or Safari.

Step 2

You will be asked to enter username: cusadmin and password:<the Wi-Fi network password that you configured in the Quick Setup>

Step 3

Click on wireless choose basic settings should already be selected 2.4 tab will be selected by default.

Step 4

Change the channel bandwidth switch 20/40 MHz to 20MH

Step 5

Change the wireless channel from auto to any of the channels in the drop down menu choose channels 1, 11, or 6. Try to pick the emptiest of the three, try using a Wi-Fi Analyzer as your guide if your able to.

Step 6

After selecting a channel  save changes






5G bandwidth


Step 1

Login to the modem using a web Interface

  • Enter http://192.168.0.1 into the address bar in your web browser Chrome, Firefox or Safari.

Step 2

You will be asked to enter username: cusadmin and password:<the Wi-Fi network password that you configured in the Quick Setup>

5wifichannels.png

Step 3

Click on wireless choose basic settings should already be selected 5G tab will be selected by default.

Step 4

Change the channel bandwidth switch 20/40 MHz to 20MH

Step 5

Change the wireless channel from auto to any of the channels in the drop down menu try to choose channels 36, 40, 44, and 48 are the best 5G channels WiFi because they are least likely to overlap with other channels or try using channels 149, 153, 157, and 161 as they are also less likely to overlap with other channels.

Step 6

After selecting a channel  save changes

Band steering

When connecting a device to your home network, most WiFi modems prompt you to choose between two frequencies: 2.4 GHz or 5 GHz.Band steering automatically connects your devices to the most appropriate WiFi frequency in your home.


Steps to enable band steering

Step 1

Connect to your modem using a wired Ethernet cable or join your Wireless network

Login to the modem using a web Interface Enter http://192.168.0.1 into the address bar in your web browser Chrome, Firefox or Safari


Step 2

You will be asked to enter username: cusadmin and password:<the Wi-Fi network password that you configured in the Quick Setup>

Step 3

  • Click on wireless
  • Click on the Advanced tab
  • Ensure that the Band streeting is Enable
  • Click save changes

Disabling Bandsteering

When Band Steering is disabled, you can create two separate networks (or SSIDs), each with its own password and name. You can then connect specific devices to a specific network, either 2.4 or 5G.


Steps to disabling  bandsteering

Step 1

Login to the modem using a web Interface

  • Enter http://192.168.0.1 into the address bar in your web browser Chrome, Firefox

Step 2

You will be asked to enter username: cusadmin and password:<the Wi-Fi network password that you configured in the Quick Setup>

Step 3

  • Click on wireless
  • Click on the Advanced tab
  • Ensure that the Band streeting is Disabled
  • Click save changes

Separating 2.4 and 5G Bandwidth

To separate networks band steering will have to be disabled, for both 2.4 and 5G networks

Step 1

Connect to your modem using a wired Ethernet cable or join your Wireless network

Login to the modem using a web Interface

  • Enter http://192.168.0.1 into the address bar in your web browser Chrome, Firefox

Step 2

You will be asked to enter username: cusadmin and password:<the Wi-Fi network password that you configured in the Quick Setup>

Step 3

  • Click on wireless

Both the 2.4G and 5G the Network Name (SSID) can be adjusted so it is unique for each (ie add 5g after the 5GHz
