Administrators managing wireless networks should follow these best practice guidelines:
Use the strongest wireless protection technology/protocol possible (WPA2, 801.x, and so on).
If WPA/WPA2 Personal is used, the shared network key should be long and complex.
Change the default administrator password on the access point, and make the new password longer than nine characters.
Keep wireless client software and wireless drivers patched and up-to-date.
Consider the potential "leak" of wireless network transmissions when designing wireless networks.
