My wifi occasionally crashes - occasionally bringing down the whole system with it.
My usual fall backs don't work. I've tried each of the following:
(note - I don't really know what I'm doing with modprobe - just trying anything I could think of.)Code:sudo systemctl restart networking sudo service networking restart sudo ifconfig wlp2s0 down; sudo ifconfig wlp2s0 up sudo modprobe -r iwlmvm cfg80211 mac80211 iwlwifi sudo modprobe iwlmvm cfg80211 mac80211 iwlwifi
I'd like to know how to bring it back up without restarting.
Because the problem freezes the whole system, I'd also like to stop it from happening completely, if possible.
Here's some more information about the problem.
My computer:
ASUS UX303U (Very happy with it, by the way, portability AND specs/price ratio was good - and I need both for work)
I've tried using kernels:

I believe this only happens after the laptop has been suspended or hibernated, then awakened, though I'm not completely sure on that.
I also tried turning bluetooth off (saw something about that somewhere with this chip), but that didn't seem to help.
