I've tried fresh installs of Debian, Debian Lite and Ubuntu Mate, but my wifi doesn't show up.
In Debian Lite I followed this guide: https://www.raspberrypi.org/documentation/configuration/wireless/wireless-cli.md
In Ubuntu Mate I tried plugin in an ethernet cable to upgrade everything possible, but it didn't help.
I can see lots of other wifi networks, but mine is not showing up.
This is my wifi info, seen from OSX. It is not a hidden network.
