on another 2-meter cable, the Internet works normally in the console with the Netduma R3 connection, on the current 12-meter cable it does not work, but on the same long cable when connected to the TV it works, when I connect the long cable to the computer it also works, on the previous 12-meter cable which broke down, the console worked normally, so I have no idea what's going on 🥺, and on this long cable without netduma , when Connecting directly to the modem, the internet in the console works

That's really bizarre, some sort of weird incompatibility with that cable, the router and the console then? Never heard of that before! At least you've got that sorted, well done!
