I've used versions of that wireless keyboard/trackpad combo and they've all been pretty dissapointing for connection quality, input accuracy, and longevity. I hope his model is hardwired in and works better, or that he's got spares.
Is this a joke? You can literally just splice together some Ethernet cables and all the devices will work unless there’s some specific configuration on the router to prevent that.
… stepped away to confirm my prior knowledge…
Well maybe not, seems like CSMA/CD (used for the above mentioned connectivity) is not as commonly implemented as it once was.
