    This post reads more like an opinion than a question. What exactly are you looking for here? – Jeff Schaller Mar 18 at 13:20
  • A reopen vote given (5 are needed). Also I had many troubles with a pci ath card, despite that it is written as a good thing for linux wifi. I think the problems are more in the hardware than in the software. – peterh Mar 19 at 15:21
