Altri problemi relativi al wifi - Qualcomm Atheros QCA6174 ath10k_pci

Il mio wifi ha funzionato bene fino a poco tempo fa. Avevo messo i file da kvalo / ath10k-firmware.git in / lib / firmware come da No Wifi in Qualcom Atheros - Ubuntu 16.04 - Acer Aspire E 15 e problemi con Qualcomm Atheros QCA6174 in Ubuntu 16.04 e altri.

Tuttavia, ho ancora grossi problemi. Anche collegare un dongle wifi ha problemi, ma un problema alla volta - il problema è sicuramente questo dispositivo. Il resto dei dispositivi sulla mia rete va benissimo.

Esecuzione di Ubuntu 16.10 su laptop Acer Aspire V15 Nitro.

Penso che potresti soffrire di un paio di problemi diversi. Voglio che reinstalli il pacchetto Ubuntu linux-firmware poiché potrebbe essere più aggiornato del sito github di kvallo

sudo apt-get install --reinstall linux-firmware

Una recente modifica al gestore di rete abilita il wifi powersave per impostazione predefinita, per disabilitare questa operazione

sudo sed -i 's/wifi.powersave = 3/wifi.powersave = 2/' /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf

Reboot
