On the xFi app, my wife saw a device she didn't recognize and paused it. It turns out it was my new laptop, and she didn't recognize the name. She unpaused it when we figured out that is what had happened. The computer has (partially) not functioned correctly since.
Specifically, there are two, highly-connection-dependent programs (Hearthstone and Skype) for which the laptop WILL NOT MAINTAIN A CONNECTION. I can browse the web, read e-mail, watch Youtube videos, etc. But as soon as I launch Hearthstone, I experience continuous "disconnected from server" messages. Same thing with Skype.
