I have a lenovo ideapad laptop. I installed Ubuntu 16.04.02 in it and the WiFi works really bad. It randomly work fine, disconnects by itself, sometimes doesn't show the available WiFi networks, and even when I get a connection it eventually disconnects.
Is there any known problems, and solutions, for this ?
The output of the command lspci -knn | grep Net -A3
is:
02:00.0 Network controller [0280]: Qualcomm Atheros Device [168c:0042] (rev 30)
Subsystem: Lenovo Device [17aa:4035]
Kernel driver in use: ath10k_pci
Kernel modules: ath10k_pci

These newer Atheros wifi cards do not work well with power management enabled. You can disable power management with
Reboot
