My wifi was working fine in previous version. But, after upgrade wifi broke. It won't show any wifi networks and I couldn't enable wifi from ubuntu panel on top right corner. I tried almost all suggestions in this page and few other askubuntu pages with same problem: http://askubuntu.com/questions/62166/siocsifflags-operation-not-possible-due-to-rf-kill But, nothing worked. Here is my console output: ~$ sudo rfkill list 0: dell-rbtn: Wireless LAN Soft blocked: yes Hard blocked: yes 1: phy0: Wireless LAN Soft blocked: no Hard blocked: no 7: hci0: Bluetooth Soft blocked: no Hard blocked: no Then, I ran "sudo rfkill unblock wifi" but that didn't fix anything. Finally, the only thing that worked was: sudo modprobe -r dell-rbtn I don't even know if this is the right way to fix it. Please fix the 16.04 kernel and OS upgrade package so that other users don't face this problem that cost me 2 days. Thank you.
