Hi Lars and Vincenzo,
I'm seeing the same issue -- all of my existing RJ45 cables do not "click" into my Almond+ and I have to push them in pretty hard to get them to connect. Also, they get disconnected extremely easily -- if I move my Almond+ slightly, they can get disconnected. Once they're connected though, it's fine... as long as my Almond is laying down. I don't think I could ever mount it to the wall unless I bought some new ethernet cables that actually "click" into the jack.
Lars, thanks for providing this feedback to the engineering team, it's quite frustrating.
