"Just the facts, ma'am."
1) Went to the Ubuntu Developer Summit. On day 2, the wireless stopped working on my Daru2. lspci didn't even list the device.
2) I get home from UDS: before I take apart laptop I boot it just to make sure. wifi works (and obviously listed in lspci)
3) I go to Minneapolis for holidays. Wifi doesn't work again, and no listing in lspci.
4) I got home Monday. Today I boot it to make sure one more time before I purchase a replacement wireless controller, and wouldn't you know it, it works again.
Does my laptop just get home sick?
If it is a dieing piece of hardware: what should I replace it with when it dies? What type of device is this called?
