Connecting a WiFi Router to Arris TM722G

Follow these step-by-step instructions to connect a WiFi router to an Arris TM722G cable modem:

  1. Ensure your equipment is ready: Unpack your WiFi router and Arris TM722G cable modem. Make sure you have all the necessary cables: an Ethernet cable (usually supplied with your router), and a power cable for both the router and the modem.
  2. Position your devices: Place your cable modem and router in a central location. Ideally, this should be near a power outlet and close to where you will most frequently use your WiFi. Avoid placing your devices inside cabinets or behind other electronics, as these can interfere with your signal.
  3. Connect the cable modem to the power source: Plug in the power cable to your Arris TM722G cable modem and then into a power outlet. Wait for it to start up completely. This is usually indicated by the lights on the modem. You should see a solid power light, and the downstream and upstream lights should be blinking or steady.
  4. Connect the cable modem to the Internet: This is typically done by plugging a coaxial cable into the “Cable” port on the back of your cable modem. The other end of this cable should be connected to your Internet service provider’s (ISP’s) connection or cable outlet.
  5. Connect your router to the cable modem: Take your Ethernet cable and plug one end into the Ethernet (also known as “LAN”) port on the back of your cable modem. Connect the other end of the Ethernet cable into the “Internet” or “WAN” port on the back of your WiFi router.
  6. Power up the router: Connect the power cable to your WiFi router and then plug it into a power outlet. Wait for it to start up completely. Depending on the model, the power light should come on, and the Internet or WAN light should start blinking after a minute or so, indicating a connection with the modem.
  7. Configure your router: To do this, you will need a computer or a smartphone. Follow the instructions provided with your router to connect to its network, either by using a supplied network name and password or by connecting directly with a cable. Once you’re connected, open a web browser and type in the router’s IP address, typically something like “” or “”. This will take you to the router’s configuration page.
  8. Set up WiFi: On the router’s configuration page, you should see options to set up your WiFi network. This typically includes setting a network name (or “SSID”) and password. Make sure to choose a strong password to secure your network. Also, select WPA2 or WPA3 as your security type, as these are the most secure.
  9. Save your settings and test your connection: After you’ve configured your WiFi network, save your settings. Your router will probably restart. After the restart, you should be able to see your new network from your wireless devices. Connect to the network using the password you created.
  10. Troubleshooting: If you can’t connect to the internet, restart both the modem and the router by unplugging them, waiting a minute, and then plugging them back in. If you’re still having problems, contact your ISP or the manufacturer’s customer service for further assistance.

Remember, your modem and router might be a little different depending on the model and brand, so if you’re having trouble, check the instruction manual that came with your devices.
