WiFi OFF P.M.

I do not use WiFi when I am aslee, so why leave it on to drain the battery? This rule turns WiFi off at a set time at night. Another rule turns it back on 1/2 hour before I wake up.

WiFi ON A.M.

I keep WiFi off when I am asleep (to save battery power). This rule turns it back on in the morning. (I set the trigger for this rule to turn WiFi on 1/2 hour before I wake up so any email sent to me during the night will be waiting for me.)
