I have two OS in my computer: Windows 7 and Ubuntu 16.10 (I installed it today). I'm trying to connect to the wifi and it doesn't work. My Ubuntu is recognizing all the connections available, but my machine only connects through Ethernet. I'm beginner in Linux, but I did some tests. Apparently, I have a Wireless Driver.

cassia@Cassia-PC:~$ sudo iwconfig
enp2s0    no wireless extensions.

lo        no wireless extensions.

cassia@Cassia-PC:~$ rfkill list all

    See if my answer @ http://askubuntu.com/q/673156/300665 helps at all. I would check iwlist scan | egrep -i 'ssid|cipher' and see if your access point is using TKIP as that causes problems. I have the same wireless chipset using 16.04 with no connection issues but I am not using TKIP – Jeremy31 Feb 26 '17 at 00:11
  • Jeremy31, apparently my problem was in my router configuration. I put my Mac Address in my Control Access of the Router. – Cássia Feb 26 '17 at 01:04
