Weird WLAN problem after stupid upgrade attempt

[Mitch Bradley]

If you revert to Q2D07, does "test /wlan" work again?

Q2D07 and Q2D08 have different versions of the wlan firmware wad.  
Perhaps there is something about your wlan hardware that works with the 
wlan firmware image in Q2D07, but not with the one in Q2D08 and not with 
whichever version is in your OS version.  That is one of the only two 
hypotheses that come to mind.  The other on is the possibility that 
there is something flaky about the onboard USB connection, so that the 
device sometimes enumerates and sometimes doesn't, depending on subtle 
factors.
