I'm having problem with my wifi adapter so I emailed customer support. The rep told me to provide him with the output for
iwconfig. Then he told me to send him the output for
iw dev [interface] scan.
I was not permitted to run that command so I had to add
sudo and redirect the output to a text file. I read the text file but there's a lot of information in there that I don't understand. Can someone explain to me what
sudo iw dev [interface] scan does?
