The “US” and “DS” lights on an Arris modem indicate the downstream and upstream data connection, respectively. The downstream data connection refers to the connection from the Internet to your home network, while the upstream data connection refers to the connection from your home network to the Internet.
The “US” light will typically be solid when the upstream connection is stable and will flash when there is activity on the connection. Similarly, the “DS” light will be solid when the downstream connection is stable and will flash when there is activity on the connection.
If both the “US” and “DS” lights are flashing, it could indicate a problem with the connection. In this case, you may need to troubleshoot the issue to get the connection back up and running.
If the “US” and “DS” lights on your Arris modem are flashing, it could be a sign of a problem with the connection. This could be due to a variety of factors, such as an issue with the modem itself, a problem with the coaxial cable connection, an outage in your area, or interference from nearby electronic devices.
If you notice that the “US” and “DS” lights are flashing, you may want to try some basic troubleshooting steps to see if you can resolve the issue on your own. These could include restarting the modem, checking the coaxial cable connection, and checking for outages or interference. If these steps don’t resolve the problem, you may need to contact your Internet service provider (ISP) for further assistance.
Why is the US/DS light flashing?
The US light represents the upstream connection or the connection from the modem to the internet service provider (ISP). The DS light represents the downstream connection or the connection from the ISP to the modem. If either of these lights is flashing, it could indicate a problem with the connection.
It’s important to note that the meaning of the light’s flashing can vary depending on the specific modem model. For example, some models may use a solid light to indicate a normal connection, while a flashing light could indicate a problem. It’s a good idea to consult the manufacturer’s documentation or contact the manufacturer or your ISP for more information on the specific meanings of the lights on your modem.

How to fix a flashing US/DS light
Check the modem’s connections
The first step in troubleshooting a flashing US/DS light is to check the modem’s connections. This can often be a simple fix if there is a loose or disconnected cable.
Here are a few specific things to check:
- Make sure that all cables are securely connected to the modem and the wall outlet. Check both ends of each cable to ensure that they are fully plugged in.
- Check for any visible damage to the cables. Look for any frayed or broken wires, and replace any damaged cables.
- Make sure that you are using the correct cables. The modem should come with a set of cables that are specifically designed to work with it. Using the wrong type of cable (such as a phone cord instead of an Ethernet cable) can cause problems with the connection.
If you have checked all of the cables and they seem to be fine, the next step is to restart the modem.
Restart the modem
Restarting the modem can often resolve issues with the connection. To restart the modem:
- Turn off the modem and unplug it from the power outlet.
- Wait a few minutes (around 5 minutes is usually sufficient). This gives the modem time to fully power off and can help clear any temporary issues that may be causing the problem.
- Plug the modem back in and turn it on.
- Wait for the modem to fully start up and establish a connection. This may take a few minutes.
- Check to see if the US/DS light is still flashing. If the light is no longer flashing, the problem may have been resolved.
If the US/DS light is still flashing after restarting the modem, the next step is to check for any known service outages in your area.
Check for service outages
If the US/DS light is still flashing after restarting the modem, the next step is to check for any known service outages in your area. Service outages can be caused by a variety of factors, such as maintenance work, weather events, or other issues with the infrastructure of the internet service.
To check for service outages:
- Contact your ISP and ask if there are any known outages in your area. You can usually find contact information for your ISP on their website or your monthly billing statement.
- If there are outages, you will need to wait until service is restored before the US/DS light will stop flashing. Your ISP should be able to give you an estimated time for when service will be restored.
If there are no known outages in your area, or if the outages have been resolved but the US/DS light is still flashing, the next step is to check for wireless interference.
Check for wireless interference
If you are using a wireless connection, interference from other devices or appliances in your home can sometimes cause problems with the connection. To check for wireless interference:
- Try moving the modem to a different location. Sometimes, moving the modem to a different part of the house can help improve the signal and resolve connection issues.
- Try using a different channel on your wireless router. Different channels can be less congested and provide a stronger signal, so switching to a different channel may help improve the connection.
To switch the channel on your router:
- Access your router’s configuration page. This is usually done by typing the router’s IP address into a web browser. Consult the manufacturer’s documentation or your ISP for the correct IP address.
- Look for a setting called “channel” or “wireless channel” and change it to a different channel. There are usually several options to choose from, such as channel 1, channel 6, or channel 11.
- Save the changes and test the connection to see if it has improved.
If changing the location or channel of the modem does not help, the next step is to check for firmware updates.
Check for firmware updates
Sometimes a firmware update can help resolve issues with the modem’s connection. Firmware is the software that runs on the modem and helps it connect to the internet. Updating the firmware can sometimes fix bugs or other issues that may be causing problems with the connection.
To check for firmware updates:
- Check with your ISP to see if they have any available updates for your modem. Your ISP should be able to provide instructions for how to install the update.
- If your ISP does not have any available updates, check the manufacturer’s website for updates. Look for a section on the website dedicated to supporting or downloads, and follow the instructions provided to download and install the update.
Keep in mind that updating the firmware can be a somewhat technical process and may require some basic computer skills. If you are not comfortable updating the firmware yourself, you may want to consider contacting your ISP or the manufacturer for assistance.
If you have tried all of these troubleshooting steps and the US/DS light is still flashing, you may need to contact your ISP or the manufacturer for further assistance.
