The WEP (Wired Equivalent Privacy) implemented in 3Com's wireless PCI card is based on an RC4 encryption algorithm and provides a 40-bit security key to ensure data conﬁdentiality. This WEP security protects your wireless LAN against eavesdropping and unauthorized access by hackers or other intruders. If the WEP is in use, the WEP key is required for connecting to an access point or listening to messages that pass through the air.

To use the WEP function, take the following steps:

1Click on the Encryption tab to set up WEP security keys.

2Select Enabled for the WEP ﬁeld.

3Select one encrypted key (from Key 1 to Key 4) as your default key.

4Click the Apply button.
