How to link a device to a distant computer using an Ethernet connection?
Brought the remote computer inside and connected using a known working cable, achieving the same result as before. It seems the issue might not be the cables but something altered on the computer itself. Windows updates can affect settings, so it may need to be turned off completely if possible. Otherwise, I’m uncertain about other changes and will need to explore the settings further.
This suggests a hardware issue, not a software one, at least according to you.
It seems that two of the jacks on the router aren't functioning properly. After connecting the cable to the other jack, the lights turned on and the computer became connected.
