It is a frequent issue with the brand-new Kindle Fire tablet. Your Kindle Fire doesn't seem to be able to connect when you attempt to get WiFi to function on it. These are the most likely causes: It's not in airplane mode. It's possible that a network or modem function is hindering the connection. Restarting the device, waiting 15 minutes while it reboots, and then checking in again is a different approach that never works.
