Did PN51 come with networking supported by default? When I got my PN50 some time ago, it couldn't connect to either wireless or wired networks and there was no indication which manufacturer's driver was required without some disassembly. I also loved how they shipped a CD with a computer that has no means of reading it with included drivers, so that was completely unhelpful. Why is installing drivers still a thing in 202x in non-Macs?
