In most cases, it’s a symptom of poor connectivity and low-quality or no signal if the US/DS light blinks every second.
Let’s find out why the US/DS light keeps blinking.

Why is the US/DS light blinking?

Once an internet connection has been established, the US/DS light will stay on for a short period of time before returning to its steady state. When your router’s light keeps blinking, it implies that the internet connection has been interrupted. The following is to blame for this snafu:

  • Defective modem: An unreliable modem is the most likely culprit when it comes to connection problems.
  • Loose or disconnected wiring: Such a circumstance can also be caused by loose or damaged cable, which could result in the loss of internet service.
  • Service outage: Another possible cause of this issue is the internet service provider’s (ISP’s) scheduled or unavoidable service interruptions in your location.
  • Splitter problem: When the splitter used to connect to the Internet is destroyed or fails to work properly, the Internet connection may be interrupted.
  • Firmware update: It is possible that an ISP firmware update will result in an unending blinking of the US/DS indicator.

Fortunately, there are workarounds available if your modem’s US/DS light is blinking due to any of the aforementioned or other circumstances. Let’s now look at some possible remedies that could help you deal with this issue.

How to resolve the US/DS blinking light problem?

For problems with US/DS blinking light or “modem not connecting,” use any of the following methods.

Restarting the modem is the first step in troubleshooting because a defective or broken modem is at the top of the list of possible causes. To make your modem work again, follow these instructions:

  • Unplug the modem and turn off the electricity.
  • Hold on for a moment.

Solution#2: Check the Cable & Connections

Check the coaxial cable’s cable wiring for any problems, as well as the coaxial cable’s connections on both ends. Reattach, tighten or fix any loose connections that you discover. As a precautionary measure, it is recommended that you detach the cable and reattach it again.
In the event that you can’t fix the wires on your own, you should contact in a cable repairman. It is necessary to contact your Internet service provider if the problem persists.

During an outage, the US/DS light may flash as the modem stops receiving signals or even if it does, the signals are feeble. Either call your ISP or check their website or app to find out what’s wrong and whether it’s related to a service outage.
Wait for the outage to end and the service to return to normal before doing anything else, if it has been confirmed.

Solution#4: Check your Splitter

Your splitter may potentially be malfunctioning or damaged, which could be the root cause of your issue. Remove the splitter and connect the coaxial line directly to the modem to determine if the problem is caused by the splitter or not.
The splitter was causing the problem, and you need to replace it if you can no longer encounter the issue when you connect the cable straight.

Solution#5: Contact Support

If you’ve tried everything listed above and still can’t fix the problem, it’s possible that your ISP is to blame. As a result, you need to contact the support team to get the issue resolved.
