I'm having trouble connecting to my WiFi Network on my Lenovo y50-70 LapTop on Ubuntu 16.04. I had it run on Windows for the first couple months, so I am positive, that it does have WiFi capabilities. I didn't have any such problems on my old Lenovo LapTop on Ubuntu 14.04 however. I just installed the OS, but couldn't install updates or set the clock with that. Now it doesn't show any wlan connection at the menu on the top right. It does show a wired Ethernet connection however, when I go Edit Connections.
I tried:
-rfkill list all & sudo rfkill unblock all which seemed to remove a softblock on my wlan
-I can't install the proprietary BCM drivers since I don't have an Ethernet port.
-ifconfig wlan0 & ifconfig wlan0 up -> wlan0: error fetching information: Device not found & wlan0: ERROR while getting interface flags: No such device
-iwconfig
lo no wireless extensions.
enp9s0 no wireless extensions.
