Connect your PC to the router for better internet access.
I suggest boosting the Wi-Fi range instead of switching to a power line adapter. I verified that your router, PC, and other devices are on separate circuits.
It's unclear for certain, but it seems it isn't Cat5/5e. The far right wire appears red, and possibly a black wire is present, suggesting it might not be an Ethernet cable for the main run. This could relate to the jack rather than the entire house wiring. To confirm, you'd need to remove the plate or jack entirely and inspect the wires directly. There might be a small set screw on the bottom edge of the plate. If you take a photo of the full wall plate, it would help clarify the situation. Usually, such plates detach easily with a bit of prying if no visible screws are present.
Ended up checking the coaxial socket next to my PC by connecting the router to it, and it functions properly. Considering buying the Moca Adapter (Amazon link). My router lacks a WAN port and only accepts the coaxial cable. Should I use a splitter to send signals to both the adapter and router via coaxial, or should I connect the adapter to the router's LAN port instead? It seems to work as shown in the video.
Router LAN port connected via MOCA adapter → Coax cable → MOCA adapter → PC LAN port. If only a single coax port exists near the router, a splitter may help, but you’ll need to confirm this step.
