Find assistance for Ethernet socket outlets.
This design has some downsides. The router needs to be placed inside the communication box or close to the Ethernet patch panel, which is usually a hard-to-reach spot for optimal WiFi coverage.
If you own an apartment, you might also reach out to your management company for assistance if they offer such a service. My relative's unit didn't even have cables connected to the patch panel—cables were just hanging inside the communication box, not properly attached. As a result, none of the jacks in the suite functioned. I had to contact the management company to resolve the issue, which turned out to be a technical defect (the construction team had forgotten to install it).
There are routers on the upper floors, so if a box is downstairs I might as well run Ethernet from my kitchen to the upstairs room. Thanks again for your help! I’ll check the area and see where I can proceed, or reach out to my management if I can’t find anything. Appreciate it! 
You're not grasping the concept. The jack from your room goes to a box via one cable, and another cable from the router reaches the same spot. You use just one cable and connect its ports on the panel side with a 1-foot cable, creating a single long connection from your room to the router. To have all ports working in the house, you'd need a switch or relocate the router.
The ISP won't even attempt anything beyond the router. But based on the comments above, it seems clear...
