2016-08-15 11:58:38 -0500 asked a question How to restart NetworkManager and wifi in fedora 24?

I think there is a problem in wifi driver and firefox my fedora 24 .(Acer Aspire E5 , intel i3 ,)

Sometime after booting firefox tends to freeze and wifi connection is gone out. Though I get out the situation using

Alt+tab to switch into another window.

I thought systemctl restart NetworkManager will work . But it did not . I had to reboot again. This link may be helpful. Whenever I try this , this does not help.

[ppaul@pi ~]$ iwconfig

It is showing. I can't identify what is happening . It is very annoying bug , I have to restart again and again. Can anyone suggest what to do?

for convenience following is supplied .

I have Acer Aspire E5 laptop . From Ubuntu I shifted to fedora 23 . Thene sometimes I faced the problems of freezing . Recently I upgraded to fedora 24 . After some days same problem is arising in much more severe form . After using 20 to 30 minutes hardly system goes to freeze . Keyboard is not working nor touchpad .

Now my question is , Is it hardware problem of my laptop ? Or some software issue caused by improper installing . Please help me . I am in serious condition .
