Configuring WEP on the VT2542
Use Wired Equivalent Privacy (WEP) if you have wireless clients that do not support WPA.
1 Check the Enable WEP Wireless Security box to enable the setting.
2 Select the Authentication Type (Open, Shared, Both) from the pull down menu.
3 Click the SECURITY tab to display the page.
4 Check the key field (0 — 3).
5 Enter the encryption key.
6 Select the cipher (64, 128, 256) size from the pull down menu.
7 Click Save. You must restart the wireless system in order for the changes to take affect.
Caution!
If you use WEP encryption, you must configure the same WEP key on the VT2542 access point and all
wireless clients (stations). Never provide your WEP key or passphrase to anyone who is not authorized
to use your WLAN.
WEP
Authentication
Sets whether shared key authentication is enabled to provide data privacy on the WLAN:
• Open System — Any WLAN client can transmit data to any other client without
authentication. It is the default, if the Security Mode is set to WEP.
• Shared Key — The VT2542 authenticates and transfers data to and from all clients having
shared key authentication enabled. We recommend this setting.
Encryption Use a WEP key length that is compatible with your wireless client adapters. Choose one of:
• Enable 64-Bit — Use only if you have wireless clients that do not support 128-bit encryption
• Enable 128-Bit — We recommend this setting for stronger encryption; it is supported by the
Motorola WN825G and WPCI810G wireless adapters and most current wireless adapters
Key Type
(Key 0 to Key 3)
Select the active key (0 to 3). Only one key can be active.
• Four 10-character long key 64-bit WEP keys
• Four 26-character long 128-bit WEP keys
We recommend changing the WEP keys frequently. Never provide the WEP key to anyone
who is not authorized to use your WLAN.
