After update to 7.0.3 not able to get online
After updating to 7.0.3 Safari will not go online and my WiFi menu bar indicator is grey. However, WiFi is ON, Mail works, Firefox works and network preferences indicates that WiFi is on(green). I would like to reinstall Safari but am having trouble finding out how to reinstall just Safari. Anjother preference would be to reinstall an earlier version of Safari.
