A system and method that facilitates control of the power states of a mobile device's wireless radios. Radios can be collectively turned off in a straightforward, intuitive operation, and can be restored to a powered-on state in a similar manner. In addition to collective powering down and restoring, the power states of individual radios can be controlled in a selective manner. When any radio is on, a connectivity dialog provides a link for collectively turning wireless devices off. When no radios are on, the connectivity dialog provides a corresponding link to turn wireless radios on, which may be only those that were on prior to the collective shutdown. A settings user interface, such as accessible via a link on the connectivity dialog, provides on/off radio buttons and checkboxes that enable the selective control of radio power state.
