EZ Connect™ N Draft 11n Wireless Cardbus Adapter
Use Passphrase — Check this box to auto-generate keys for encryption. First,
check this box, then enter a string of characters into the space. Encryption keys will
be generated automatically.
When Key Type is set to 128-bit, only one key will be generated. If Key Type is set to
64-bit, four keys will be generated. Note that you must use the same passphrase and
default key on all the other clients in your network.
How to set up WEP:
If you are transmitting sensitive data across wireless channels, you should enable
Wired Equivalent Privacy (WEP) encryption. WEP provides a basic level of security,
preventing unauthorized access to the network and encrypting data transmitted
between wireless clients and the access point. WEP uses static shared keys
(fixed-length hexadecimal or alphanumeric strings) that are manually distributed to all
clients that want to use the network. WEP is the security protocol initially specified in
the IEEE 802.11 standard for wireless communications. For more robust wireless
security, the Wireless Cardbus Adapter provides Wi-Fi Protected Access
(WPA-PSK) and WPA2-PSK for improved data encryption and user authentication.
Only one key is needed for WEP to function. However, the IEEE 802.11 standard
specifies that there must be four keys for each device. For security purposes, the key
should be changed on a regular basis. Multiple keys are supported to allow the user
to change keys with minimal disruption of the network.
To set up the WEP function, take the following steps:
1. Select 40/64-bit encryption, 40/64-bit encryption (ASCII), 128-bit encryption,or
128-bit encryption (ASCII) in the Key Type field.
2. To automatically generate keys, check the Use Passphrase box, and type in a
string of characters in this field.
3. In the Default Key field, select one key as the default key that you want to use for
encryption.
4. Click Apply Change to allow the settings to take effect.
Or
1. Select 40/64-bit encryption, 40/64-bit encryption (ASCII), 128-bit encryption,or
128-bit encryption (ASCII) in the Key Type field.
2. In the Default Key field, select one key as the default key that you want to use for
encryption.
3. Manually type in a string of characters in the corresponding key number field that
you selected in step 2.
4. Click Apply Change to allow the settings to take effect.
