WiFi Cutouts And Restart Hangs

The first one is the way that the wifi stops responding. It doesn't update in the notification area when it happens, to limited connectivity or any sort of warning like that. I can only tell when background downloads I have going are interrupted, but it seems really inconsistent why and when it happens. I've been unable to pinpoint and reduce the number of potential causes, not for a lack of trying. I disconnect from the network, and am unable to reconnect without first disabling and re-enabling the wifi adapter. This, however, presents the problem of the wifi adapter not re-enabling, and before that, the Network Sharing Center window in which I do it, will not update to the disabled state without a window refresh.

This leads to the other issue, is that when and only when this wifi issue happens, on restart, it hangs while showing the dark gray screen that says "Restarting..." with the spinning circle. The spinning of the circle happens continually, but will not advance further, even being left for close to an hour.

Every other wireless device (mobile phone, laptop, game consoles, etc) continue to function, so the network itself doesn't seem to be having an issue.

A thought I had, though I don't know how much water it may hold, is that something could be acting funny with a power saving/hibernate function, as I said, I've just been downloading when I notice it happening. I'll start a download, let it do it's business, continue on with my business elsewhere, and almost to no fail, a few hours later, upon returning and checking the current status of said downloads, I have to restart. I don't have it set to go to sleep/hibernate, but I'm not sure if there's other power save options in Windows 8, as this is the first desktop I've owned in recent memory and was surprised as is to see power options on it at all. It also seems like one of the network services could be acting strangely, with it not updating the notification area or adapter windows without manually forcing it.

I've scanned with Windows Defender, Malwarebytes and ran CCleaner, and nothing out of the ordinary was presented in the scan results.
