Things to consider before hooking up Arris modem to wireless router

You need to do a few simple preparations before you can connect an Arris modem to your router; otherwise, the connection won't work.

There are two major things to consider ahead.

Check for compatibility

To see if your Arris modem is compatible with the router, follow the steps outlined below:

  • Start your computer and launch your internet browser.

  • Look for the correct Arris modem model

  • Enter "Is my Arris (Model) modem compatible with (Router type)" in the search window of your internet browser.

  • Finally, verify the findings to ensure that your Arris modem is compatible with the network router you intend to connect it to.

If your router is found to be compatible with the Arris modem, you may proceed.

Check for compatibility

Get an Ethernet cable

An Ethernet cable is the next thing you'll need to connect your router and an Arris modem.

This sort of cable is commonly used in network connections and typically offers a single device with direct internet access from the router.

In this instance, an Ethernet cable will be required to connect your Arris modem and router, as this is the only way to link both devices.

Get an Ethernet cable

Note: If you already have an Ethernet cable connected to your computer, you can disconnect it and use it on the Arris modem.

Because your router can accept multiple Ethernet cables, you can connect both your Arris modem and PC to it via Ethernet cable.

Disconnect ethernet and power

Locate the Ethernet wire linked to your Arris modem and disconnect it immediately.

Then, unhook its other end, which is linked to your PC, and unplug the modem's power adapter from the power supply.

The modem will sit between your PC and router. We will install the Arris modem in the center.

Unscrew the Coax cable and MP

Connect the coaxial connection to one of the Arris modem inputs. 

If you previously used a modem, disconnect the coax cable and gently remove the MP (modem attenuator pad).

Once ready, connect the coaxial wire to the Arris modem and, if necessary, connect the modem attenuator pad.

Unscrew the Coax cable and MP

Connect Ethernet cable

After disconnecting both ends of the Ethernet cable, reconnect the end that was formerly connected to your PC into the router's internet port. 

Then connect the other end to one of your Arris modem's ethernet ports.

The Ethernet wire should now be connected to the Arris modem from the rear of your router.

Connect the device

Take a second Ethernet cord, insert the first end into the router's accessible slot on the rear, and the other end into your computer.

To avoid downloading new drivers for the cable, use the same PC port that you previously used with the modem.

Connect the device

Deliver power

By connecting them to a power source, you can power both your router and Arris modem.

The devices should be linked and functioning as intended after they are turned ON. This is how to connect an Arris modem to a wireless router.

If it still does not work, keep reading as we will be setting up a new network in the next steps.

Self-activate the modem

  • Ethernet or WiFi should be used to connect your computer to your router.

  • On your PC, launch any online browser.

  • The activation page will be instantly redirected to you.

  • The steps will help you activate your modem.

If this doesn't work for you, make sure your computer is wired or wirelessly linked to your router.

Your ISP is always available to help if you are still unable to activate the device on your own.
