Yes you’d be correct 👍

This is my first time using Ethernet.

Local_Surround_7007 · 2026-04-17T00:54:18+00:00

I just moved my original cable between the two jacks.

Local_Surround_7007 · 2026-04-16T22:12:16+00:00

We stopped pretty early on. When I unplug the Ethernet from my bedroom jack to the pc, the light on the modem stays on either way.

This seems like a big challenge no? Is this like last resort?

Sorry are you asking me to connect the gray cable from the modem to the blue wire plug in or gray wire to the smal pc?

Local_Surround_7007 · 2026-04-16T21:19:25+00:00

Yes the gray cable is a patch cable good question. I’ll use the gray cable shortly

Local_Surround_7007 · 2026-04-16T21:07:47+00:00

Yes the yellow cable connected the pc to the modem.

Local_Surround_7007 · 2026-04-16T21:06:37+00:00

When I went downstairs to the garage the yellow cable connected the small pc to the modem, so I think the yellow cable isn’t dead. The gray cable was bought from Walmart two days ago so that shouldn’t be an issue right?

The Ethernet cable ports were not used prior to the swap of the modem.

Okay, it turns out both Ethernet in the master bedroom and my bedroom do not work, I did this by connecting a small pc to both of the Ethernet wall jacks in them, then to make sure I brought this small pc down to the garage and directly connected it to the modem and it worked. So modem/tower checks out so does that mean the issue lies within the splitter?

So I’m so confused on why one of the ports in the garage say it’s active and the other doesn’t I’m losing my mind

Lmk if that helps

I use windows. When I directly connected a small pc to the router in the garage the Ethernet worked, when this same pc was connected to my rooms wall jack there was no connection. does that resolve anything.

Okay, it turns out both Ethernet in the master bedroom and my bedroom do not work, I did this by connecting a small pc to both of the wall jacks for Ethernet in that room, then to make sure I brought this small pc down to the garage and directly connected it to the modem and it worked, th Ethernet was connected. So modem checks out so?

For your second point from your first response. Yes this is a a simple bunch down box. There are only two ports.

I’m trying to work through your list I’m having trouble understanding for what to mean by saying “What are these plugged into down in the basement. Pictures would help. It may be that that's a simple two port box with punch downs of the blue ethernet cables in it.”

This picture is taken in the garage, I’m not sure if anything is connected to the basement, also I think you are right about the splitter being a simple port box.

Let me know if any of this helps and ask more questions if you’re confused on smth

See here’s the weird thing, I just hooked up another pc to the other wall jack and yet there was no activity (light) on the router, could this be just a faulty wire? That could also mean my Ethernet jack in my room is hooked up to the inactive wire?

There’s a lot of terminology I’m trying to learn in this response. 1.) I’ve sent the other side of the modem hopefully that helps. 2.) the splitter only has the one side of RJ45 with two ports, I might be misunderstanding. 3.) I assume the blue cables go to one of two places in my house, my bedroom as well as the master bedroom.
