My wireless driver seems to be down, and as a result my WiFi no longer works. I've tried disabling/enabling it from the device manager as well as shutting down and booting the system back up to no avail.
Windows 8 does not do a full shutdown unless you explicitly tell it to or disable fast startup from the power management settings. I temporary solved the problem by executing
shutdown /s /t 0 from the command line and rebooting, but this doesn't prevent the wireless card/driver from eventually failing again. Something I'm still seeking a solution for.
