My Kindle Fire frequently disconnects from my WiFi during sleep mode. Pressing the on button in WiFi settings does not work so I have to reboot to get the WiFi back. My WiFi works fine with any other device. Has anyone else had this problem? Solutions? Thanks!
Before you decide to return it to Amazon, test the Fire on a different wireless connection or router and see if the problem still occurs to make sure it's not the router that is the problem.
