Network Connection Error

[Pacman.]

so since i got my epic every so often it will have a blue pop up that says network connection error, and says try again or cancel. some times it wont do it for a few days sometimes it will happen many times on one day. its not to bad just annoying and i dont know if i missed something while it was in that state. so has anyone else experience this, i took out most of my widgets to see if thats what it was it but no. so any help would be great
