Hey I recently installed froyo to my nook color. It works great so far, but I do have one glitch. Any time that the device is powered down (not merely put to sleep) the wifi does not turn on when powered on again. This problem does not occur when going from sleep to awake. Their is an icon for "airplane mode" in the task bar at top, but it says that airplane mode is off. When i go to settings and turn on the wifi, it works fine and does so until the next power down. Is there a way to have wifi automatically start when u reboot?? It is not something that is a huge problem, just a minor inconvenience.
