Yesterday, I installed Fedora 27 on a Dell Venue 8 Pro (5830). I installed the ath6kl firmware from https://github.com/qca/ath6kl-firmware/ The Wi-Fi works for a while, but then stops. It seems to start up again about 30 minutes later. Is this a known problem ? Is there any to fix it ? FYI, I added : echo options ath6kl_core debug_mask=0x140400 > /etc/modprobe.d/55-ath6k.conf ... so I'm getting more debug info. Are the other debug bits I should try ? Thanks
