Shaw Modem Flashing Green (How to Fix)

If your Shaw modem is flashing green, it typically signifies that it’s trying to connect to the internet, a process called Upstream registration. This is normal during startup, but if it lasts longer than usual, it may indicate a connection issue.

Quick fixes include restarting your modem, checking coaxial and Ethernet cables, switching coaxial outlets, and confirming ISP service status.

Why Does My Shaw Modem Flash Green?

When your Shaw modem’s LED light flashes green, it’s typically part of the boot-up sequence, known as Upstream registration. This happens when you turn on the modem, reboot it, or reset it to factory settings.

During Upstream registration, the modem is trying to establish a connection with Shaw, your Internet Service Provider (ISP). Once the connection is established, the modem can send and receive data over the internet.

Here’s a simplified sequence to help you visualize:

Turning On the Modem: Just like when you start a car and wait for the engine to get ready, when you turn on your modem, it needs a moment to prepare to connect to the internet.

Restarting or Resetting the Modem: Similar to turning it on, if you restart your modem or reset it to its original factory settings, it’ll go through the same process of getting ready to connect.

Connecting to Shaw: The blinking green light means your modem is talking to Shaw, your internet provider. This process is called Upstream registration.

Ready to Go: Once the modem and Shaw have finished their ‘conversation’ and everything is good to go, your modem can start sending and receiving all the internet data you need.

Step-by-Step Guide to Fix a Shaw Modem Flashing Green

1. Restart Your Modem (Power-Cycle)

Let’s start with the easiest solution:

  • Press the power button on your modem to turn it off.
  • Next, unplug the modem from its power source. This helps clear any minor glitches.
  • Wait about a minute. During this time, your modem will reset itself.
  • Plug the modem back in and turn it on by pressing the power button.
  • Check to see if the green light has stopped flashing and turned solid white.

2. Check the Coaxial Cable

Your coaxial cable needs to be in good shape:

  • Take a close look at the coaxial cable. Make sure it’s not damaged or frayed.

  • Check that the cable is tightly connected at both ends – where it plugs into the modem and the wall.
  • If you have an extra coaxial cable, try using it to see if the problem goes away.
  • If you’re using a splitter, try removing it and connect the cable directly to the modem.

3. Try a Different Coaxial Outlet

Another outlet might work better:

  • Disconnect the modem from the current coaxial outlet.
  • Plug the modem into a different coaxial outlet in your home.
  • See if this change allows the modem to connect to Shaw successfully.

4. Check the Ethernet Cable

Make sure your Ethernet cable is okay:

  • Inspect the Ethernet cable for any damage or wear.
  • Ensure it’s securely plugged into both the modem and your router or computer.
  • Try using a different Ethernet port on the modem to see if it makes a difference.

5. Confirm ISP Service Status

Sometimes the problem is on Shaw’s end:

  • If there’s an outage, you’ll need to wait for Shaw to fix it.

6. Factory Reset Your Modem

If nothing else works, try resetting your modem:

  • Find the small reset button on the back of the modem.
  • Use a paperclip to press and hold this button for about 20 seconds.
  • Let go of the button and wait for the modem to reboot. This will erase your settings and return the modem to its factory state.

7. Contact Shaw Technical Support

If you’ve tried all the solutions without success, it’s time to seek professional help:
