Is your connection on your Tablet out? I have the same issue, but the clock on the upper right corner of my tablet is correct...It also says my wifi is connected at full bars, but I keep getting connection failure messages when trying to use the Internet or apps...I reset the weather app's cache and reset the data, it reset the time properly but I still don't have proper internet connection...I also reset the modem, still nothing...my phone is using the wifi perfectly
