Connection Keeps Dropping

Thanks in advance for any help you can offer. I’ll try to be as detailed as possible.

I’m running Windows 8.1 Pro 64 bit. I’ve got a 250 GB SSD which stores all my essential files, and an internal 1 TB HD which stores my media. I’m streaming to my Nexus 5, an Apple TV second generation, and a Wii using Homebrew.

It will stream just fine for a while, then the apple TV will read something like “cannot find file or directory” and can’t access the files. Sometimes it works for days, sometimes less. None of my devices will be able to find the files when this happens. Usually if I restart my computer, it’ll work again for a while.

I also installed Air Control and have been using an app on my phone to control my Apple TV. The app does the same thing, all of a sudden it will stop working. 

I’m at my wits end and cannot figure out what the problem could be. Any help, even pointing me in the right direction, would be incredibly appreciated.
