I've used Unix for over 25 years, Linux for over 17. It's my platform of choice, I very, very rarely use anything else.
And my Thinkpad T520i listing a "03:00.0 Network controller: Intel Corporation Centrino Wireless-N 1000 [Condor Peak]" under lspci and running Debian GNU/Linux jessie/sid has _never_ had reliable WiFi, and I run it essentially 24/7 with a Cat5 cable plugged into hardwire networking.
I've tried network manager, wicd-cli, wicd-curses, and other tools. I can see networks. I cannot connect to them. Plugging a cable in solves the problem far faster than futzing with a nonintuitive, low-feedback/diagnostics interface.
So yeah, you're probably lucky.
