WEP
WEP (Wired Equivalent Privacy) is a standard for encrypting data before
it is transmitted.
This is desirable because it is impossible to prevent snoopers from
receiving any data which is transmitted by your Wireless Stations. But if
the data is encrypted, then it is meaningless unless the receiver can
decrypt it.
If WEP is used, the Wireless Stations and the Access Point must have
the same settings for each of the following:
WEP Off, 64-bit, 128-bit.
Key
For 64-bit encryption, the Key value must match.
For 128-bit encryption, the Key value must match.
WEP
Authentication Open System or Shared Key.
