I have a Windows 8.1 machine that was working perfectly fine up until tonight.
I went out and bought a Chromecast so I could be a bit more productive in my coding (cast the web page with the programming information I need up onto the TV and use my entire laptop screen for the IDE), and, well, that's gone to waste. Like you're supposed to, I went to Google's website and downloaded the program to connect to the Chromecast and set it up. I ran it, and when I got to the part of the setup where you have to connect to the network, I couldn't get it to work. I then switched over to my Android tablet and... ta-da... it worked. The Chromecast was able to connect to the network and I was able to cast tabs to it from my laptop.
I lost my internet connection on my laptop sometime thereafter. Now, no matter how many times I restart my computer, tell it to forget the network it was on, sign back in (password and all) to the network, "reset" the network adapter, or unplug/plug the router or modem... it won't connect. What's up here and how do I fix it? Other devices still connect fine.
