Recently bought a house...and we had an electrician come to install some grounded outlets. I told him while he was running wire through the walls that while he had the hole open, I wanted to run some Ethernet cable for my computer. He recommended he put in a ethernet port as it would look cleaner. So I figured he may as well install one at the tv, and my wifes office. So he installed a 3 port jack at the router, and single ports in my office, living room and wifes office.. he explained that it works like an extension cord...so I have it set up as modem>router>3 cables to 3port jack>office... but I can't get a connection in my office. I've been reading up on it...and it seems like i need a switch..and that the set up is completely wrong. Did this electrician have no idea what he was talking about?

Edit: the set up for the jacks themselves are 3 cables connected to the 3 port jack...and each cable running to a separate room

It might, depends on what the fault actually is.

He probably terminated one end with B connections and the other with A or something if he was reading the instructions on the block.

Anyhow, it sounds like you need to punch them back down in the correct sequence at both ends.

Wait... router? if your router has enough ports you can plug directly in there.
modem->router->three port jack.

If it doesn't or is too far, locate a cheap 20 dollar five port switch near the jack cluster and do as you described.
modem>router>switch>3cables to 3port Jack

The router and modem are side by side... but it's not working when I go modem>router>3 port jack

The router has 5 ports... I assumed it would work if I plug 3 cables from the router to the 3port Jack...and then connect a cable from computer to single port jack in office

So we're assuming the router works. OK for the sake of argument, can you take a pic of this three port jack of yours ? Imgur or another host is fine.

You already have a switch built into the router, we don't need another in the mix.

Wish he would have labelled them. But yes those are standard drops, I have no idea which one runs to your office, but if you hook up all three to the router or try one at a time you should be getting a signal in the office. It's literally that simple.

I've kept a cable plugged in at my computer to the Ethernet jack in my office... then I tired moving the cable connected to my router between all 3 ports... none of them give me a signal. The cables he ran are cat 6...the only cables I have from router to jack and jack to computer is cat 5e. But I read that doesn't matter

Well that's annoying as hell. He must have terminated one of them wrong and it's likely the one you want to use.

cable type doesn't matter at all in this case as you said.

As long as the patch cables are tested and working, the PC is tested and working, the router is tested and working, that leaves the new wiring as defective.

Now when you say he terminated one of them wrong, do you mean he didn't connect the cat 6 to the port correctly? Is this something that can be fixed if I pop the outlet off?

I think it was a punch tool... maybe I'll call him back. I paid him to install it correctly, therefore he should fix the issue.

Baaaaahh....so annoying.
I'll try out one of the other single port jacks in another room in the morning.

Unlikely he wired three of them wrong. I mean it's possible he repeated the same mistake terminating all three, but that looks like a pro job.

Here's how I understand what is going on;
So there are three drops (runs of cable) to different rooms. Those runs are terminated in the three port jack in an entirely different room where the router is located?

If I understand what you are asking correctly, then yes... that is the lay out.

Kitchen has the router, and the 3 port jack. There are 3 runs of cable running from the 3 port jack, one to my office, one to the living room, and one to my wifes office.

I see this here every day. I really wish those guys would actually test after wiring it all up.

After you wire in a new ceiling light...what the first thing you do? Flip the switch to verify that it works.

Here, we are completely unsure what the issue is, because it was seemingly never verified actually working with your hardware.
