Hello UPC!
We have just moved to a new-build apartment in Ruschlikon, and our bauleiter has advised us that the apartment has built-in powerline networking. He advised us to install the UPC box in the closet and connect it with the socket shown below in pictures, which then ensures internet via each room’s ethernet port. Unfortunately, the new cables provided by UPC don’t work here (the one for the 2-socket plugs, with red and blue ends).
Are you familiar with this? Do you know where I can get an adaptor/another cable that works with this setup? As per my tests, if there was a cable that was the “red” plug (from the cables mentioned above) on both ends, that would likely work - the “blue” plug is too small to fit into the sockets.
Any help would be greatly appreciated!
