NDC comm NWH4020 manual Troubleshooting

Disabled (default): Stations communicate with the access point without any data encryption.

40-bit WEP: Stations communicate with the access point using 40-bit WEP data encryption.

128-bit WEP: Stations communicate with the access point using 128-bit WEP data encryption.

In order to decode data transmissions, all wireless stations on the network must use the same key or keys.

WEP Key Generation: There are two ways to generate a WEP key or keys.

The first is by entering text in the Passphrase box and then clicking Generate. For 40-bit WEP, four WEP keys will be generated: Key 1, Key 2, Key 3, and Key 4. Using the Default Key control, select the key currently in use on the network. If you do not select a key, key 1 will be selected. For 128-bit WEP, a single key will be generated.

The other WEP key generation method is to click in the key input boxes and input values directly from the keyboard in hexadecimal notation. If the key is not entered correctly, the station will not be able to join the network. If WEP is enabled on the AP, all stations must use the same WEP key to connect to it.

Authentication — The Authentication control can be set to Unspecified (this is the default setting), Open System, or Shared Key. The setting of this control is ignored when WEP is disabled.

When 40-bit or 128-bit WEP is enabled, the setting of this control determines whether or not the station’s requests to join the network will be WEP encrypted.

The Unspecified setting causes the station to try joining the network with both encrypted and unencrypted requests. In Open System authentication mode, requests are never encrypted. Shared Key means that the station’s requests to join the network are always encrypted.
