If you are trying to beef up on your wireless network knowledge, you may wonder what is US/DS on a router. The best routers, after all, typically offer metrics regarding US/DS. So what is US/DS and how can you use this information to your advantage? Keep reading to find out.


  • US/DS, or US DS, stands for upstream and downstream and is an indication of the efficiency of the signal coming into your Internet router and going out from your Internet router.
  • To check on the status of your US/DS connection, check for the solid green LED modem lights on the front of your router.
  • If your lights are constantly blinking, it could indicate a problem with the connection coming from the modem via coaxial cable. Unplug devices via the power socket, restart the router’s power cycle via the power button, and try again.

What is US DS on a Router?

Simply put, US/DS stands for Upstream/Downstream. When a router establishes a connection, it does so via an upstream connection (sending information) and a downstream connection (receiving information.) To establish a solid Internet connection, both upstream and downstream signals must be operating correctly, otherwise, you may have to learn how to unbrick a router.

Insider Tip

In most cases, your US/DS lights will turn solid green and stay that way until the next time the modem or router resets.

How to Tell if US/DS Router Connections are Working?

The easiest way to do this is to simply check your Internet connection, no matter if you have a 2.4GHz connection or if you are wondering about the definition of a 5GHz connection. If you can access websites or other Internet applications via connected devices, you should be good to go.

Another way to check on the status of your US/DS connection is to take a look at the lights at the front of your router. There is typically an upstream LED light and a downstream LED light. Upon an initial connection, these lights will blink, but once a connection has been successfully established the blinking should stop and the lights will turn green. It’s important to ensure these lights are working correctly, especially if you’ve connected two networks with a single router.

Why are My US/DS Lights Blinking Forever?

In some cases, these LED lights can blink continuously, causing frustration to router owners. If your lights are constantly blinking at one-second intervals, this typically indicates that you are receiving a low signal or no signal at all. This is a problem with your actual Internet connection so your best bet here is to contact your Internet service provider (ISP.)

Other reasons your US/DS lights keep blinking? There are a few. Severe power fluctuations, power surges, and power outages can cause these lights to constantly flicker. Your best bet here is to restart the modem and router. In some cases, if you are using a splitter to send your Internet signal to several devices at once, including multiple routers, you could experience these flickering lights. Check your connections and try again. If your current router is failing, you might want to compare Netgear Nighthawk routers to find a replacement.

It depends on what is causing the issue in the first place. Check the coaxial cable or Internet cable and the power source for all devices. Look at the online light at the exterior of the router and cable modem to ensure you receive a strong cable signal.

How to reset my modem?

Hold down the power button or reset button for 30 seconds to reset a modem. Then check the online light on the exterior of the cable modem.

This follows the steps for any Internet modem unless you have a defective modem. Simply unplug the device and leave it unpowered for a couple of minutes. Next, plug it back in and look for solid lights.

STAT: While P2P systems had previously been used in many application domains,[4] the concept was popularized by file-sharing systems such as the music-sharing application Napster (originally released in 1999). (source)
