> do you have unusual hardware?
No. I do tend to use old hardware, but tried it on a mainstream new laptop one time. On that, I couldn't get the WiFi to work with it.
What baffles me is that on all of these machines, Debian works out of the box. In fact, Debian's never failed me on any of the many machines (including laptops) I've put it on.
Ubuntu is based on Debian, so I can't explain the difference. As I said, it's been a while and perhaps they've fixed issues, but I've moved on. My life is no poorer for it.
The only thing is that it means I can't recommend Ubuntu to people (not only because I wouldn't be able to support them if they have trouble, but what am I supposed to say? "I can't make it work, but use this!"?)
