Ethernet cable quality
In fact, I'm a bit surprised we're revisiting this topic, but I should mention something I missed. @mariushm @Needfuldoer @Lurick Will UTP be sufficient? For reference: The main router sits on the ceiling of my second floor, while the target router is also mounted there. The cable will then be placed against the wall at the edge of the ceiling (not behind it). It should run alongside some CCTV coax+12v power cables down to the first floor to reach the target router. There will need to be at least 1.5 meters (4.9 ft) separation between the cable and any electronics. The wall is made of concrete.
