I usually don't use the wireless card (lack of habit I suppose), but it's good to know anyway. I Googled this question and found some information that suggest that the OS needs to support this. This project is an example: https://github.com/HSAFoundation/HSA-Drivers-Linux-AMD Other interesting links: https://community.amd.com/message/1308713#1308713 https://community.amd.com/message/1306778#1306778 Thanks! > > Best regards, > Matthias > > > > Am 2015-08-23 20:18, schrieb Fernando Apestegu=C3=ADa: >> >> Hi all, >> >> I am thinking of changing my old laptop and a friend of mine talk to >> me about the AMD A series.
