What does this mean? If you're using WEP, your network and data are at significant risk. The best-case scenario...
is that you might have unauthorized individuals using your network and consuming your bandwidth. More nefarious individuals, however, might use your network for illegal activities: activities that would be traced back to your IP address range. Thieves might conduct corporate espionage, stealing your organization's private data as it flies around the wireless network.
The bottom line is that you should make the investment to upgrade your wireless gear to support WPA encryption. It's the responsible thing to do.
