A little info on my setup for my console: My Wii U is connected via ethernet adapter running to the ethernet adapter on my PC. My PC receives internet via wireless adapter. I share that wireless signal to the PC's ethernet adapter using windows internet connection sharing, giving my Wii U internet. I originally used this setup whenever I was playing online games to get better latency. My console is too far to run cable to router and my PC's wireless adapter gets much better connection than the Wii U's. I am also unable to change block settings on my modem/router. So, if I block all the update URLS on my PC's internet using something like Zonealarm, would that also block it from my Wii U?
