My new Surface RT device conect to wifi network at home and works fine. However, when I close the tablet and put it into sleep mode using power putton, the tablet stays connected to wifi. If I use Messaging, facebook or skype app, my friends sending me messages will think I am onine but actually I am offline. Is there a solution to make it disconnect wifi?
Microsoft Windows 8 and Windows RT tablet is similar to Smart Phones. They use Connected Standby (S0iX) power state that allows email, and other connected apps to receive data in low power sleep state.
To solve the problem, you have to setup each app to turn off them from running in the background or lockscreen. Swipe from the right screen within Messaging app, tap/click Settings > Permissions, and disable Lock Screen option.
