title_body: Kindle paperwhite loses the Wifi connection all the time
upvoted_answer: This appears to be a known issue with the Kindle Fire. I'm assuming it is also an issue for your model. I would suggest that you just broadcast your SSID. Most people report this is fixes the issue. If you are not broadcasting it for security reasons, that is what encryption and password are for. If someone wants to break into your network, hiding the SSID is not going to what stops them from getting in. There are many freely available programs that can detect non-broadcasting networks.
