How to Fix US DS Blinking Light on Spectrum Internet Modem?

Here’s how you can fix the US DS blinking light on your Spectrum Internet modem:

1- Rebooting the Modem

A simple reboot helps clear the modem cache and re-establish the connection with the internet service provider. For this:

  • Unplug your Spectrum Internet modem from the power outlet
  • Let it rest for about 1 minute
  • Plug it back in and turn it on
  • Let the modem establish a connection (check the lights for stability)
  • Connect your router or your computer, and check for connectivity

2- Modem Reset

If the modem reboot wasn’t able to fix the US DS blinking light problem, then you can reset the modem. For that:

  • Find the reset button located behind the modem
    • It’s usually a small hole with ‘reset’ written for an indication
  • Find a small pin that can fit the hole
  • Insert the pin, press, and hold until the lights turn off
  • Let the modem rest until the lights turn on
  • Wait for the modem to establish connectivity, and then check for connectivity using your computer

3- Changing Cables

It’s possible that rebooting or resetting the modem doesn’t fix the US DS blinking light issue. In that case, inspect the cables for damage, especially the connectors that secure the plug-in. If the cables are damaged, replace them with new ones.

4- Checking the Splitter

A coax splitter is used when you’re connecting a modem and a Spectrum TV Receiver in the same cable outlet. There’s a good chance that it might be causing the US DS light to blink continuously. For this:

  • Unplug the splitter and connect it directly to the modem’s adapter
    • If this works, the coax splitter is damaged, and you’d need to change the splitter

5- Contacting Spectrum Customer Service

If you’ve tried the abovementioned fixes and the problem persists, it’s a good time to call for support. You can contact Spectrum customer service to report the issue, who will diligently assist you in solving the problem.
