ethernet connection not working

Hey there. I had ATT Fiber installed a month ago. I've tried hardwiring a tv and a gaming console using two different ethernet cables in to different ethernet ports installed in the house, one upstairs, and one down. Neither device notices they are plugged in at all. If anyone has any thoughts about this, I would love some help. Thank you.

please make sure those cables are not crossover cables they look the same as regular ethernet but should be marked accordingly.

Okay. I will check. I’ve never heard of such. So I appreciate that information very much.

Confirm those existing Ethernet ports have rj45 connectors and are wired for Ethernet as opposed to wired for phones. I believe wired for phones would have only 2 wires to the connector.

So I haven’t been able to find anything labeled as “crossover”. But here is the title for one of the cables I tried: “

RJ45 Cat-6 Ethernet Patch Internet Cable”

Plug them in directly to the gateway to confirm they connect. If they connect directly to the gateway, your in wall wiring is the problem.

This is a very good idea browndk26. Thank you. I'll post an update when I've had the opportunity to test the cables.

I finally got the chance to check my cable by plugging it directly into the router. It worked. It is a bit hard to tell the colors in the end of the cable, but I can tell that they are all different colors with red being at one end and orange being at the other. So no pattern either way. My guess is that I’m going to have to call the builder on this one. Thank you for your help.

I have a similar issue where my wifi is working without issue, but the three ethernet connections have issues every several days that require a modem reboot. I ran 50 foot cables from the modem to my workstation and to a bedroom Apple TV. I have a third cable that is 10 feet that runs from a second Apple TV to the modem. This has been an ongoing issue since we switched to 1Gig back in November. They have replace the modem once to see if that's the issue. I have not changed any of the default settings on the modem.

Any help would be appreciated.
