Mine took forever to connect and was always going to sleep. I had 10% per hour battery drainage too, so perhaps that was related to the KT trying to constantly connect. But who knows--I'm speculating. I don't have WiFi connection issues with any other device (desktop, netbook, Kindle 3, iPad, iPod touch) so I assumed there might have been a hardware issue. That's why I returned my KT to Borders just to be safe, especially since Borders might get liquidated soon.
