Can I ask a potentially quite dumb question - why not buy a long ethernet cable and run it from the router to where the monitor is? I’m having a tough time imagining why you can’t easily manage to have it connected to the monitor/keyboard/ and the router at the same time. After that, you can move it to adjacent to the router.
Also, rereading, perhaps you don’t even have a monitor and keyboard/mouse if you just have a laptop? If you don’t have those, you won’t be able to set up the ROCK. You do have to push a few buttons. Not a lot, especially if you use one of these little bad boys, but you do need to have it connected, and a NUC or NUCbox won’t come with it’s own - not sure if I’m misreading your post, so apologies if I am.
