I have a new Lenovo laptop running Windows 8 and a Linksys wireless router.
While using it, the wireless notified me that it was not connected. Tried unplugging and replugging modem. Now it reports that it's connected—but with a little exclamation mark that says
Security: Unsecured
Type: 802.11g
Is this a safe connection? If not, what should I do to fix it?
