WEP Settings
The Wired Equivalent Privacy (WEP) is a security protocol for wireless networks that encrypts transmitted data . WEP is easy to configure with only three possible security optionsOff (no security), 64-bit (basic security), and 128-bit (stronger security). WEP is not difficult to crack, and using it reduces performance slightly.
If your network operates with WEP turned off, your system is very open for someone to access your data. Depending on the sensitivity of your data, you can choose between the 64-bit and 128-bit encryption. Although the 128-bit WEP encryption provides greater security, it does so at a performance cost. 64-bit offers less impact on system performance and less security.
As far as troubleshooting is concerned, in order for wireless communication to take place, wireless devices must all use the same WEP setting. Most devices are set to Off by default; if changed, all clients must use the same settings.
