Correction - The last line above, should instead be

  "
Device: Realtek 802.11ac NIC type:  USB driver: N/A bus-id: 3-7:4 
chip-ID: odba:c811
"

As the computer cannot connect to the Internet, the line was read on the 
affected computer, and typoed into another computer.

I believe that the third-last character, being wrongly entered as a '9', 
when it should have been an '8', is the only error in the typing of that 
line of text.
