Built in Ethernet wall ports

[Faust87]

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

So. I believe I have found the issue. He used type a connections...and all my wires are type b. Can he just repunch the cables and swap the orange and green cables? Or do I need to get new wall jacks all together?

that doesn't matter if he terminated both ends the same though.

That is correct. Other possible cause (if not a misconfigured wiring) is DNS resolution. Sometimes newly hook up computers have hard time resolving DSN connections. Try using the same primary/secondary DNS server IPs (ex. Google, OpenDNS, Quad9, etc.) on router & your computer.

Alright, so I took off the wall jacks to see how he connected them. He connected them all to 568a pattern, where my cables are all 568b type. So all the cables I'm using from router->wall, and wall->computer as jumpers weren't carrying the signal...maybe?...total assumption. I configured the wall cables to 568b and now everything works!

that's all that's important. But the cables weren't dictating that. just think of them as extension cords and what really matters is the house wiring. You fixed it, damn straight. Happy surfing
