Here are the issues I'm seeing with the new Kali 2.1 image.

-Can't SSH as root - work around:
-Can't XRDP as root - can XRDP as non-root user
-wi-fi - dosen't work - naming weirdness
-Can't wake-up when power saving event occurs - have to reboot and start again
-X11/XMING redirect using putty doesn't start Wireshark

I just confirmed all these issues are not present in Kali 2.0.1 - everything works fine.

Is there a way to download the older version?
