Title:
wifi broke after 16.04 upgrade
Status in linux package in Ubuntu:
Expired
Bug description:
I upgraded from ubuntu 14.04 LTS to ubuntu 16.04 LTS. 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.
