I generally like my laptop, but one thing that it hates is wireless internet. After two years of struggle, I finally effectively ceded the issue upon moving into my Virginia apartment, connecting to the internet via a direct landline.
But upon moving to my new place in Chicago (which I love), I foolishly decided to break that ceasefire, and attempt to set up a new wireless network. Oooh, the laptop didn't like that, and it retaliated by destroying the ability to connect even through a landline.
Wireless internet remains at the laptop's discretion, which is why I'm able to post this message from the airport. But things are not looking peachy right now.
