What you have shows that network manager does not recognize your wifi hardware. Also the last command was meant to be:
inxi -n
Also as @bruno suggested:
rfkill
That is a good basic command for this type of problem, and I forgot. 
As far as I know if the network icon in system tray does not show your wifi router or connection that could be a connectivity problem or an incompatible hardware problem.
Time to throw in that I am not a developer, don’t know code, like what of the interaction on this forum is users helping users. We can take a issue to developers. So we need to take the info provided above by @WilsonPhillips investigate if that wifi device or it’s driver is the issue, or if there is some kernel module needed and so forth.
And last a helpful hint for forum etiquette:
