Comment # 4 on bug 1045694 from Tomas Kuchta

Post install I mean:
1. Install basic default system with KDE up to graphical login screen.
   Do not connect to network during install
   There is one reboot, I believe
   Do not update the system during instal
2. There is no Wi-Fi functional
   The only networking available is via ethernet, if you have it.
   You can reboot as many times - Wi-Fi does not work consistently
   The wifi is visible in HW info, but it is in off state and cannot be turned
on
   There is no wlan0 device
   If you plug in some USB Wi-Fi dongle - that works
   if you plug in some USB ethernet dongle - that works too
3. Update + reboot the system - if you can somehow connect to network without
the wifi
   There is wlan0 interface and the Wi-Fi works as expected

I hope that this helps,
Tomas
