How to Troubleshoot a Coax and Internet Connection

Learn > Coax Cable Tester > How to Troubleshoot a Coax and Internet Connection

If your cable modem is having issues like slow speeds and frequent disconnects, and you aren’t sure what the issue is, you will need to do some troubleshooting.  Sometimes it can be difficult to tell whether the issue is with your cable modem or with your coaxial wiring. At any given time, your home’s coaxial cabling can be vulnerable to damages such as pinching and rubbing on the wire. This can occur when someone accidentally bends or pinches a cable just by stepping on it (like if it is in a high-traffic area like a doorway or under a rug). Even though you’re unsure where the issue is, there is an easy way to accurately pinpoint where the problem is originating: use a coax cable tester.


A coax cable tester – like Hitron’s DSS-01 Coax Cable Tester – can help you troubleshoot your connection by telling you if your coax is receiving an Internet signal from your cable Internet provider. This can immediately identify if the issue is with your cable modem or your coax wiring.  By identifying where the issue is, you will be able to decide if you need a professional technician visit or if the issue can be resolved at home. Besides troubleshooting your coaxial wiring, the DSS-01 Coax Cable Tester has quite a few benefits, including:

  • Fast test results on the state of your coax in less than 10 seconds
  • Accurate testing designed for Major Cable Internet providers
  • Easy to use one-button test
  • Fits in your pocket so you can take it anywhere
  • Available for purchase on Amazon


To troubleshoot with a coax cable tester, simply plug it into the coaxial outlet or wiring you’d like to test. Once turned on, the bright, LED-light indicator will blink either red or green. Red means your coax is not receiving an Internet signal, while green light means your coaxial is receiving a signal. If your coaxial wiring and outlet are working, and have ruled out any issues with your cable modem, you can contact your cable provider to do a more in-depth look into your current issues.


Using a coax cable tester can help make troubleshooting your coax and internet connection quicker, less costly and less complicated.
