That is the typical error for MS not getting an IP address.  When Windows 
ZeroBrain Config changes channels (for totally random reasons) it does a 
DHCP request.  If it times out, you loose your IP, and you see your favorite 
bubble.  Often APs will fail to pass DHCP in a timely fashion. A reboot 
often fixes it.  On the other hand, a kernal panic in m0n0 will dump the 
kernal, and fill the ram drive, preventing DHCP from writing to the file. 
You can confirm this from the status.php page with a "df" command, or but 
powering up a PC on the network in question.
