Plug-In Your Modem
-
Find the best location for your modem. It’s best to place it in a central spot in your home, off the floor and near an active cable outlet. (Some cable outlets in your home may not be active.)
Tip: If you’re installing your modem in a hard-to-access spot take a picture of the white label on the bottom of the modem, so you can easily reference the default Wi-Fi network and password later. -
Connect the coax cable from the wall outlet to the connection on your modem.
-
Plug your modem into a power outlet.
Make sure all connections are finger-tight.
Wait for the Light
Wait up to 15 minutes for the Online light (shown here) to go from blue to a steady green.
Online light isn’t on or still flashing after 15 minutes?
Here are a couple of quick things to check:
- Make sure you’re using the coax cable we shipped to you and that the connections are finger-tight.
- When you first plug into power, the Online light should appear blue before it changes to steady green. If it didn’t appear blue initially, try a different power outlet.
- If the Online light doesn’t light up, or if the light is solid but it’s still not connecting, reboot the modem. Unplug it from power, wait 30 seconds and plug it back in.
Still not working? Go to page 6 for troubleshooting steps.

What’s next?
Take Note of Your Wi-Fi Network
On the bottom of your modem, find these settings for your own equipment.
A. Network Name (SSID) (This is your default network name.)
Note: There are two of them – one for a 2.4GHz signal and one for a 5GHz
signal. You’ll need to know both since the ARRIS modem broadcasts two Wi-Fi
signals.
B. Preshared Key ( This is your default wireless password.)
Connect Your Devices
With one device (such as a smartphone), go to Wi-Fi settings and connect to
the default network. (Choose the 5G network if it appears, and make sure
you’re not using mobile data.) Follow the steps on page 5 to connect to Wi-Fi.
Open a website to make sure it loads.
Want to customize your Wi-Fi network? It’s optional, but it’s best to do it
before connecting more devices. Type 192.168.0.1 into your web browser. On
the Arris page, create and enter a new password. (Important: This isn’t your
Wi-Fi password. It’s to access to your modem’s settings.) Select Next Step.
For both the 2.4GHz and 5 GHz networks, create your new Wi-Fi network name and
password.
Your passwords can be the same. Be sure to add 5G at the end of that network
name. After you save changes, the modem will automatically disconnect from the
previous network. Follow the steps on page 5 to connect the first and other
devices to your new Wi-Fi network. (Make sure you’re not using mobile data.)
Don’t want to customize your network? When connecting, make sure you’re using your modem’s Wi-Fi network, not mobile data.

Troubleshooting: Look at Modem Lights
STEP 1
Try a different cable outlet.
Not all cable outlets are active. The easiest thing to do is move your modem
to another location and plug the coax into a different outlet.
Online light is flashing one color.
STEP 2
Wait 10 minutes to see if it connects.
If the lights turn solid green, go to the Take Note of Your Wi-Fi
Network steps on page 4. If you’ve tried multiple outlets and still can’t
connect, call support at 1.800.888.1300 or text 64326.
STEP 1: MODEM UPDATE
Wait for your modem to update.
Like all hardware, your modem sometimes needs an update (even if it’s new).
This can take up to 60 minutes, so feel free to check back in a bit.
When the update is done, both lights will show solid green.
If the online light is still blinking after 60 minutes, reboot your modem.
Unplug it from power, wait 30 seconds and plug it back in. Then, give it up to
60 minutes for a complete reboot and update.
When the light shows solid green , it’s complete and time for you to go
to the Take Note of Your Wi-Fi Network steps on page 4.
STEP 2 (IF YOU’RE STILL HAVING ISSUES)
Perform a factory reset.
If you’ve tried everything else and the online light is still blinking, then
it’s time to try a factory reset.
With your modem still powered on, press and hold the Reset button – found
on the back of the modem – for 10 seconds.
(You need a pen or paper clip to push it.) Once the online light is solid
green, go to the Take Note of Your Wi-Fi Network steps on page 4.
If this doesn’t work, please call support at 1.800.888.1300 or text 64326.
