My friends and I recently moved into a townhome where the previous owner had the entire place wired with CAT5 Ethernet. We have Spectrum internet coming in through a coaxial cable, which works fine. However, when we try to connect the router to any of the wall Ethernet ports, we don't get any signal, and the indicator lights don't light up. We've connected devices directly to the router without issues, so we know the router is functional. We also checked a closet panel where the cables are connected, but we're totally stuck on getting our Ethernet network set up. Any advice on troubleshooting this issue? Should we get a specialist or an electrician involved?

It sounds like those ports might not actually be wired for Ethernet. The previous owner might've used the CAT5 for phone lines instead. I recommend getting a cable tester to trace the lines and make sure they're actually connected to where you think they are. If they are connected but not set up correctly, you might need to reterminate the cables and connect them to a switch to make it work. Good luck!
Don’t stress too much! Most of these kinds of problems are fixable. If you find out that those cables are indeed wired incorrectly, you can attach the correct RJ45 connectors and plug them into a switch. That should help get everything communicating properly. If you’re uncomfortable doing it yourself, definitely look for a local networking specialist.
You definitely need to verify where those blue cables end up. If they connect to a patch panel in that closet, check if all the wires are correctly terminated. If so, plug in a switch there; that’s likely your best bet. If this process feels too overwhelming, a local tech can sort it out pretty quickly. It’s usually cheaper than involving an electrician.
Agreed! It's amazing how much easier future troubleshooting will be if everything is labeled. Trust me, you'll thank yourself later!
From what you've described, it sounds like the previous installation may have been repurposed for phone use. If that’s the case, those cables would need to be reconfigured. A network specialist should be able to evaluate your setup and get everything running smoothly for around $200.
Make sure that those ports aren't just wired for phone use. Check the individual wall plates to see if they are actually connected to anything. If everything checks out, you might just need to put in a network switch to connect all the cables together. Cables that appear to be Ethernet could be improperly wired for phones instead. A cable tester can help identify where the problematic connections are.
Great advice! Also, make sure to label the cables once you figure them out to save you hassle in the future!
