Q: Wifi randomly cuts out.

I've upgraded to Yosemite. Ever since then, my Wifi will randomly drop. When dropped, it will start by not showing any networks. Then after a quick restart, the wifi will either work again, have no bars (in addition to not showing any networks), or it will simply say "WiFi: No Hardware Installed". This problem is extremely frustrating and I'm surprised that it didn't cut out as I'm typing this.
