The problem we are going to talk about in this article is caused by the US/DS light blinking. To fix this problem successfully, we need to know what this light means, what are the reasons for this problem, and what you can do to fix it before you contact the support.
What does the US/DS light mean?
In case you didn’t know US stands for “Upstream” and DS stands for “Downstream”. When the router establishes connection it’s normal for the US/DS light to start blinking but it stops blinking and turns solid once the connection is established. When it’s solid it means that the internet is available and the device is ready to send and receive data or it’s sending and receiving data.
But, what does it mean when the US/DS light is blinking?
When the US/DS light is blinking or flashing in one-second intervals it means that the signal it receives is either a low-quality signal or there is no signal at all.
Why is my US/DS light blinking?
The main reasons for this problem are:There is a service outage at the momentThe coaxial cable is either disconnected or looseThe cable signal is too low
How to fix US/DS blinking light?
Now when we know the reason for this issue it is pretty easy to fix it. So, let’s see how you fix a blinking US/DS light.
1. Check for a service outage
In case there is a service outage at the moment the US/DS light can start blinking because there is no connection at all or the signal it receives is pretty weak. Therefore you can either call your ISP and ask if they are working on something at the moment or visit the ISP’s official website or app and check if there is a service outage.
Additionally, you can use Downdetector at https://downdetector.com/ to check whether your favorite services are down or having problems. You can either type in the name of the service you are having a problem with or scroll down to find and select your service from the list.
If you find out that there is an outage in your area you will have to be patient until the problem is resolved.
However, in case the US/DS light continues to blink after the outage has been resolved you can proceed with the following steps.
2. Check the connections
Check the connections on both ends of the coaxial cable and tighten them by hand. It is also recommended to disconnect the cable and reconnect it again just to make sure everything is properly connected and tight.
3. Check your splitter
Sometimes the splitter can be defective or damaged. The easiest way to check whether the splitter is causing the problem is to remove the splitter and connect the coaxial cable directly to the modem. If the problem is no longer present, the splitter was causing the problem. Replacing the splitter with a new one will fix the problem.
4. Power cycle the modem/router
Power cycling the modem or router is a simple and super effective solution to most problems. However, it is important to do it properly.
You will need to unplug your computer and modem (and router if you are using it with the modem) and after a minute plug them in again one by one – first plug the modem in. When the modem lights stabilize, plug the router in and also wait for the lights to stabilize. Finally, plug the PC in.
In most cases, this will resolve the issue.
5. Contact Support
In case you have tried everything and the US/DS light is still blinking you will have to contact support. It will definitely be much less stressful for you when you get in touch with an expert that will lead you through the necessary steps to fix the US/DS light blinking problem.
In some cases, the support will tell you that maybe the problem is on their end, or that maybe you have forgotten to pay your bills. In that case, paying the bills will fix the problem. Or they can send someone to replace your modem or router in case it’s defective and it’s causing the problem.
We hope that we have helped you fix the US/DS light blinking problem by now. Luckily, this problem can be fixed easily just follow the steps given above. If not, feel free to contact your ISP support to help you solve this problem.
