Debian 9 - installed 2 days ago. Installed firmware-misc-nonfree_20161130-3_all.deb. Os is recognizing wifi adapter and network manager is showing all the available connections. No matter what I try, it won't connect. Any tips or solutions ? Thanks

  • Try disabling bluetooth. If still it doesn't work than try live booting some other distro and check if WiFi is working. You can try Antergos, Fedora Commented Oct 12, 2017 at 5:22

  • The problem is with the WiFi driver. Can you tell on which OS was WiFi working earlier? Commented Oct 12, 2017 at 5:31
  • @ArpitAgarwal works with Windows 7 8 and 10 Commented Oct 12, 2017 at 5:32

In my own case, that could be fixed by

 $ apt install gnome-keyring

Actually I could connect to any previously saved networks, but when trying to connect to something else, nm-applet would not be able to popup the password input box, hence silently prevented me to connect to the network.
