I'm having a serious issue with my wifi. It randomly dies ALL THE TIME, and when it does the only thing that can seem to get it to work again is to completely reboot my computer (pretty annoying).
I think if I could reset it in hardware, it would do the trick -- but nothing seems to be working. I tried the solutions given by the below links -- no luck.
Result of doing sudo lshw -C network
