I cannot choose any Wifi network, nor can I activate Wifi. I am currently using Ubuntu 16.04 but I had the problem in 14.04 already. I have tried looking for answers on this forum a few times but not very actively because I used my phone's ethernet. That just stopped working too...

Solutions here do not work and I didn't understand the solution here. This is a similar problem, but my "ls | grep back; dkms status" looks like this:

sudo lshw -class network gives this
