    What is the best practice for data encryption? We use wifi and sometimes connect to unsecured networks. How can we use free encryption technology to keep our data safe from prying eyes? Even if someone gets our data I want it to be useless.

  • Appropriate configuration for adding a wireless router to a wired network

    What is the appropriate configuration for adding a wireless router to my wired network without affecting the network.
