Fix Arris modem online light blinking

The online light on most Arris modems can blink during startup or when the device is operating. If it is flashing during startup, it means the IP registration was unsuccessful.

When it blinks during operation, then the IP registration is lost. Here is how you can try to find a solution to the problem:

  • Check both ends of the coaxial cable connector of the Wi-Fi modem and wall outlet. Tighten each connector if they have come out loose.
  • Check the Ethernet cable. If you have connected it, ensure the connection to your cable Wi-Fi modem and the computer is correct.
  • Check your cable television service. In this case, ensure the service is operating well.
  • Power-cycle the gateway to allow the device to re-establish a new connection.

Troubleshoot Arris modem shows blue lights

Blue lights on the modem can mean different things, depending on the type of device you are using.

However, whenever you power on your modem for the first time, it will undergo a self-test when booting up. On completion, the Downstream light will blink GREEN.

After the modem synchronizes on a Downstream channel, the Downstream light will turn solid GREEN, and the Upstream light will start blinking GREEN.

After the device establishes a connection, the Upstream light will turn solid GREEN.

When channels are bonding, the Upstream and Downstream lights will start blinking BLUE. After the successful bonding, the Upstream and Downstream lights will turn solid BLUE.

Also, understand that a solid BLUE light will occur when the device is operating in a normal state, has finished bonding, has established an internet connection, installed the latest firmware, and the speed is more than 1Gbps.

If the US/DS light is blinking on your modem, follow this guide.

How to fix Arris modem Wi-Fi issues

Plug back the cord and wait for internet lights to turn blue, thus indicating a high-speed connection on multiple channels.

2. Check the lights

If your internet connection has a problem, you will see different lights on the device. But what color should the lights be on my Arris modem?

  • No color: If you do not see any color, your gateway is off or not receiving any power. Power it up and try again.
  • Solid red: If you see a solid red color, the device is not booting up correctly. Try another power outlet or check whether you have a damaged cord, or unplug the power cord and replug it again.
  • Flashing green and solid green: A flashing green color means the gateway has connected to a power source and needs no further action. Solid green means the gateway is on and working well.
  • Solid blue: A solid blue color means your broadband internet connection is active.

If the Wi-Fi light is off, it means you have disabled your Wi-Fi bands, and the device does not have an active connection. Solid red color means Wi-Fi network failure. Contact customer support to fix it.

But if the Arris modem keeps flashing yellow or solid green on the Wi-Fi light, your wireless connection is active and will work well once the color turns green.
