The Ethernet ports aren't functioning properly.
The Ethernet ports aren't functioning properly.
I relocated into a new home, and the Ethernet ports aren’t functioning properly. I’m trying to figure out why. Could you help me troubleshoot this issue?
Thanks for the pictures—it's quite a situation! I'd recommend contacting your service provider to report the issue and have them inspect the Ethernet connections. Since the modem is lit up, it suggests there might be a problem with the cables or connection itself.
Great! Could you share an image of the back of your modem? It might be helpful to know you’ll likely only need a RJ45 punch-down block and Cat5e patch cables.
Which modem is the back one? The photo I have shows a telephone modem, not an internet one. My internet modem uses a cable connection and is located upstairs.
A punchdown block is a device that connects Ethernet cables to a network interface card. It allows you to plug in your cables directly into the port, simplifying setup. You don’t just connect them together—you use it to link your physical cables to the network hardware efficiently.
I’m going to explain everything in detail. You’ll need to understand how to prepare the Ethernet cables, match the labeling, and connect them properly. First, you’ll work with the internal wires of a Cat5e cable and rearrange them so they fit a standard patch cable. Remember to use either T568A or T568B—preferably T568B. Next, you’ll require a switch to link all your patch cables to the modem. Prices start around $20 for basic setups with five ports, but more ports will cost more. You can also use individual connectors, known as keystone connectors, for each cable. Make sure you match the wiring colors correctly according to the labeling on the connector: blue, white with a blue stripe, orange, white with an orange stripe, etc. If you’re in the US, local technicians familiar with Cat5e networking can handle this for you if you’re willing to pay. Other countries likely have similar professionals available. Let me know if you’d like more clarification on any step.
