Conversion: Copying/Moving Files Bottlenecks PC Network Connection

Hi All,
I’ve had this problem since the start, I figured it was just my setup, but just in case I’m missing a setting somewhere that will help with it. I am grabbing and sending the source and converted files over my network, when it does, my PC loses internet and my network drives are super sluggish if accessible at all. I can see it taking about 10 minutes to transfer files, but is the shutting down of my overall network something normal, too? If I manually transfer a file between the PC and network drive, I can still browse internet and get to other drives, so thought MCEBuddy may be doing something on a system level that is taking over. I do have to remember to reboot all my devices from time to time, which helps with the transferring speeds, but it still seems to lock me out of my overall network.

Thanks!
