You mean that you couldn't reproduce the bug, ie. with the steps I gave you 
still could connect and scan for wireless networks? I ask because the failure 
is the actual bug, for example if you place let's say a sleep for 5 seconds 
between '... essid any' and '... power on' it doesn't fail.

The bug is that with that sequence, any attemps to associate or scan fail, 
where it shouldn't, at least it's what is expected.
