64-bit or 128-bit security
The IEEE 802.11 wireless LAN standard specifies the Wired Equivalent Privacy (WEP)
encryption and decryption algorithm. The standard includes two levels of security, using a 64-bit
key or a 128-bit key. Some vendors refer to 64-bit encryption as 40-bit. These are identical. A
wireless device that claims to have 64-bit encryption interoperates with a device that claims to
have 40-bit encryption.
To implement WEP
, use either the 64-bit or 128-bit method. For better security, use a 128-bit key.
A 128-bit key has several trillion times as many possible combinations as a 64-bit key. For added
security, change your keys often.
The same device, host computer or front-end processor usually performs both encryption and
decryption. The algorithm, like the pattern of a lock, is standardized and may be used by anyone,
but the encrypted data is unreadable without the appropriate key, which is known only by the
sender and receiver of the transmitted data. You should change your keys often for added
security.

PRO/Wireless 5000 LAN Mini-PCI Adapter. Features of the Intel® PRO/Wireless 5000 LAN
Adapters include:
• IEEE 802.11a specification compatibility. This open architecture allows Intel®
PRO/Wireless 5000 LAN devices to communicate with wireless devices from other
vendors that comply with the IEEE 802.11a standard.
• Up to 54 Mbps data rate for high-capacity, fast operation, including superior speeds even
at increased range
• Driver support for Microsoft Windows* XP, 98SE, Me, and 2000
• 128, 64 (called 40 by some vendors), and 0 bit Wired Equivalent Privacy (WEP) data
security and VPN compatibility
• Operation in 5 GHz UNII spectrum prevents interference from cordless phones,
microwaves, Bluetooth* or 802.11b devices
• 802.1x authentication compatibility for Windows XP
