'no wifi'

Postby gewitty » Fri Oct 27, 2017 9:30 am

I've been struggling to get wifi working on a Sony Viao. Having tried numerous suggested solutions and several alternative distros, nothing works.

I came across this thread and spotted the script for compiling all necessary info about the system, which is as follows:

Code: Select all

########## wireless info START ##########
