I know I am posting this twice, but it seems to not be just a 101 problem. It is just an observation hopefully someone smarter than me can know why it works. Not sure if the media files part applies to anyone else but me.
"I had this happen to me twice after shutting down my A101. It was also taking forever to update the multimedia library.
In both cases I had just recently made changes to my Media files. Adding or deleting.
I know it sounds stupid, but I went to "Settings/Repair and Formatting" and selected "Reset Multimedia Library". After doing that everything worked again. Even my wifi. It has worked twice for me so far. Not sure what they have in common. Perhaps just the reboot, but rebooting alone didn't work for me."
