I installed Ubuntu16.04 LTS in Acer-Aspire 5742 laptop. Every thing running well but wifi always hard blocked after 10-15 min.
- I tried to add acer_wmi, wmi, wl to blacklist /etc/modprobe.d/blacklist.conf
- I also tried to unblock using sudo rfkill unblock all but did not help.
- I am ensure wifi is enabled by hardware.
I read multiple threads but no one help me.
Out put of command : lspci -knn | grep Net -A2
