Thanks for using the forums. Sorry to hear you are having issues accessing your Slingbox. What happens to the network light on the Slingbox when you get this error code? Does it remain on or does it turn off? If the Slingbox still looses connection after resetting every day, you may want to look in to getting a replacement power supply and that should keep the network light on and steady, and then you should be able to keep the Slingbox set up.
Hope this helps,
