Comment Could also be an M.2 card upgrade (Score 1) 38
It took only a few minutes for me to upgrade my 'Legacy' 2016 model Lenovo laptop to WiFi-6 and BT 5.1 using a US$25 intel AX200 kit. It was just a matter of disconnecting the old WiFi card and installing the new one. The replaced M.2 card actually does connect at 2400 Mbps to my WiFi-6 router, though actual speeds are certainly slower. Other notebook PCs might be harder (or impossible to upgrade), but Lenovos are pretty easy to work on.
Before you try this on your own machine, make sure you research any BIOS blacklists / whitelists from your PC's manufacturer, to determine if they prevent you from upgrading hardware.
