Hello and thank you for choosing just answer.
Is it the actual wireless application that is turning off? Or is it the wireless access point, that keeps disconnecting you?
Hmmm, that is strange.
Were you ever able to get the wireless to work? I mean, has it worked in the past?
Or has this always been like this, since you got it?
Also, is the kindle a NEW device, or did you buy it USED?
