How to tell if your problem is with your cable modem or coax wiring

May 3, 2022

If you’re troubleshooting your internet connection, it can be difficult to determine where the problem is. Is the problem with your cable modem or is it with your coax wiring?

Troubleshooting your internet connection

Troubleshooting can be difficult, but by following these steps, you can narrow down where the problem is coming from. There are two options you can take to troubleshoot this situation:


Option #1 – Manually test your coax outlets:

Plug your cable modem into a different coax outlet. If you can get an internet connection on that coax outlet, then the problem is most likely with your coax outlet in that other room. But if you can’t get an internet connection, then the problem is likely with your cable modem. This method is not very accurate, however, and you may need to contact your Internet Service Provider to lend a hand in troubleshooting.


Option #2 – Use a Coax Cable Tester:

Another way to troubleshoot is to use a Hitron DSS01 Coax Cable Tester. This is a simple one-touch test that will give you instant results. The DSS01 Coax Tester will show that your coax outlet or wiring is receiving Internet signals from your Cable Internet provider, which means the problem is probably with your cable modem. But if it doesn’t detect any Internet signals, then the problem is likely with that particular coax outlet or wiring. Use the DSS01 Coax Tester to go room to room and test your coax outlets for active Internet signals. This is a very accurate and hassle-free way to troubleshoot your Internet issues.

Additional Troubleshooting Tips

There are a few additional tips to troubleshoot whether the problem is with your cable modem or coax wiring:

  1. Check all the cabling connections between your devices and make sure they’re secure.
  2. Restart your modem and router.
  3. Use the Hitron DSS01 Coax Cable Tester.
  4. If the DSS01 Coax Cable Tester shows a green light, that means your coax outlet or wiring is receiving an Internet signal and the problem is with your cable modem. If the tester shows a red light, that means there is no Internet signal detected and the issue is with your coax wiring and you’ll need to contact your ISP to get it fixed.

The Hitron DSS01 Coax Cable Tester is a simple one-touch test that gives you instant results to let you know if your coax outlet or wiring is receiving cable Internet signals from your Cable Internet provider.

Either way, the DSS01 Coax Cable Tester is a one-of-a-kind handy tool that uses patent-pending technology to help you accurately narrow down the problem so you can get your internet connection back up and running as quickly as possible.

If, after all of this, you’re still having trouble, it would be best to contact your cable Internet provider for more help.
