I am currently running Devuan Linux OS. The cable/eth0 connection WAS UP & RUNNINNING UNTIL MY INCESSESSANT FIDDLING AROUND WITH Network Manager Screwed that up too ... :-(( I have tried ALL the various Commands/Options of 'nmcli' & found that the WiFi Hardware Device/wlan0 was missing. I have searched & searched Lenovo websites to no avail. I have also spoken with a Lenovo support (NZ) technician who did not exactly inspire confidence. It was his suggestion for me to contact the WLUG. I WAS going to purchase a WiFi Adapter (onboard) from Trademe, but he thought that a PCI MINI card would be too small for this model of Laptop. The Lenovo site does not have any WiFi Adapters for sale. A friend suggested that I purchase a USB WiFi Adapter, which I did - 'tp-link AC600 Nano Wireless USB Adapter' BUT I discovered that there is not a Linux driver for it yet... so THAT was a waste of $40-odd. Anyone with a cheap old PCI WiFi or USB WiFi Adapter Driver for Linux or Any advice welcomed. Thank you for your consideration of this, my first, WLUG List Post. 'b'ye! - B. Gilbert
