So I've just closed on a new house, and for the first time, have a whole house wired for ethernet. There are 9 total cables terminating in a low voltage wall box (7 for rooms with wall jacks, and 2 behind ceiling plates for WAPs). All RJ45 connectors are terminated using the 568B standard on both ends.

Equipment:
Terrible cable company modem - verified working via direct connect

TPLink Router (https://www.amazon.com/gp/product/B007B60SCG/ref=ppx_yo_dt_b_asin_title_o01_s01?ie=UTF8&psc=1) - verified working via direct connect.

TPlink 16 port POE switch (https://www.amazon.com/gp/product/B0721V1TGV/ref=ppx_yo_dt_b_asin_title_o01_s01?ie=UTF8&psc=1) - verified working via direct connect.

I have the modem feeding into the router which is plugged into port 1 of the switch. Plugging a laptop directly into any other port on the switch works great. However, using one of the wall RJ45 jacks results in no connection. No lights on the switch, no local networking, no nothing. It's almost as if every single cable in the house is bad, and I find that hard to believe.

What am I missing here? Is it possible that there is a secondary junction box that is turned off or faulty and I just haven't found it? Have I got my switch somehow configured wrong? I'm stuck here. Next step is to go to lowes tomorrow and pickup a tester, but I'm almost sure the cables are going to carry no signal as the switch does not detect them. I've even tried replacing connectors just in case, but no luck. Please tell me I'm missing something simple here. I love a wired connection, but without working cables, I can't even get my WAPs working.

Never seen any contractor not test runs after they are done before.

You will see it all the time when that contractor is wiring 20 houses in a development all at once....
