To prioritize one network over another, again open your PlayBook's General Settings menu by tapping the gear icon in the top-right corner of your home screen. Next, select the Wi-Fi option, and then choose Saved Networks from the Select a Network drop-down menu.

Finally, locate the networks you wish to connect to, and prioritize them by touching and holding a network name, then dragging it to the top of the networks list, with the network you wish to connect to first at the top. Then simply order your networks according to how you want to connect them, from top to bottom, with your preferred Wi-Fi networks on top.

Sometimes you just don't want others seeing the websites you visit.

If you share your tablet with others, or just don't like leaving a digital trail, you may want to employ the PlayBook's private browsing feature, which stops your browser from storing certain information about where you've been on the Web. (Private browsing doesn't eliminate all traces of your whereabouts, but it covers up the majority of easily accessible on-device information, like browser history, cookies, etc.)
