I installed ubuntu 16 for like a few months, everything worked fine until last week. The wifi just went down suddenly, and I've tryied pretty much every methods on the internet and no use. (driver is installed)
And when I do ifconfig, the wlp4s0 is not showing up, iwconfig says no wireless extension.
I check couple networkconfig files, all wireless settings were enabled.
Another thing that I noticed is that, whenever I turned off the bluetooth, the network is swtiching to airplane mode.
