Today I was trying to install Steam onto my Windows 8.1 machine (wired connection to internet), and it got stuck attempting to connect to the Steam servers. I also recently was attempting to upgrade an Apple device, and iTunes also got stuck attempting to their servers. I have tried restarting, using a different user, port forwarding, and changing the "hosts" file. Nothing has seemed to help at all. I believe this might be an issue with my router, or my machine. Does anyone have an idea of what might be actually happening? Side note: Browsing the internet/downloading files works fine.
