Question One Ethernet cable to 2 rooms

[nekotism]

I think I have one Ethernet cable in the walls that connect to 2 rooms. One room has internet, the second room shows a yellow exclamation on the Ethernet icon. How can I get both rooms to connect?

How I came to this conclusion:
I recently moved into a rather new apartment and all rooms are fitted with Ethernet ports in the wall which connect to a box in the kitchen wall. I’ve been using internet fine on the PC in one room but I want to hook up another PC in the living room too. When I hooked the second PC up in the living room, windows was showing a yellow exclamation on the Ethernet icon saying I have no internet access. I tried unplugging all the Ethernet cables in the kitchen wall to see which one is connected to the living room, and when I unplugged one of the Ethernet cables, both the living room and other room’s internet showed as disconnected leading me to believe they are either sharing one Ethernet cable or connected to something else that I don’t see. or I’m just missing something.

This is the box in the kitchen. The cable with the green light under 1x is the one that seems to connect to both rooms. https://drive.google.com/open?id=1pWewT20Q_GF_OXC2fXFm1F7gdXXmRqkY

A lot of times the contractors don't 'home run' the jacks in apartments because they don't know what they're doing--I had to re-punch down the wires in one of our apartments.

I can't see the picture, but once I do, I may have some suggestions.

Thanks. Also, to rule out any issue with my second computer’s network card I was able to connect both computers to the internet without problem in the room that has internet.

so I guess the first question is, in what situation would one computer have internet and another show a yellow exclamation icon, where disconnecting one Ethernet cable from the hub (or switch?) cause both computers to give a red “X” icon?

Well, I can't see the wiring so I can't answer. There's about a dozen reasons without a picture, but with one I could probably tell you exactly why.

Actually, all they have to do is make it public, ie not require a login, and it would work where they have it.

Thanks. I just called the internet company and they sent someone to take care of it. It’s all good now.

 

[SamirD]

Nice. Did they charge you?

 

[nekotism]

No, they didn't charge me. Korean companies provide really great service. He just changed the way the Ethernet cables were plugged into the hub. Thanks again for your willingness to help!

Ah, Korea. I spent a week on Seoul when I was working for LG. I really liked it--was a very cool experience--especially the road to and from the airport.

But man, the music videos--holy crap those were really sad all the time! Nothing but love broken. Of course this was over 10 years ago so I'm sure the music has changed. Was interested to hear techno Christmas songs on the street walking around though, and I'm sure that hasn't changed. I should have bought one of those CDs.
