There's a setting that the tablet will turn off wifi when the screen is off, have you enabled that?
You can set it that when screen goes off:
Wifi can remain on
Wifi will shut off
Wifi will remain on only if the device is plugged in.
Could help you save battery as currently, wifi eats a lot of the battery. I say currently, as we could get an update in future that helps wifi eat less.
Also are you on latest firmware? I believe .26 now.
