4.5.1 WEP 

keys 

Wireless LAN offers basic protection in terms of WEP (Wired Equivalent Privacy). The Nokia 
D211 supports three key lengths: 40 (40+24), 128 (104+24), and 152 (128+24) bits. 

 

Tip:

 Regardless of how the WEP keys have been named, all keys are compatible 

as long as their length is the same. For example, keys that are 40 bits long, 
always consist of 5 alphanumeric characters or 10 hexadecimal characters. 

The 40-bit key is Wi-Fi

ä

 (Wireless Fidelity) compatible. 

Shared keys are specified in an access point and in a WLAN client. In other words, all WLAN 
clients are using the same WEP key in the same network. 

Personal WEP keys are a Nokia proprietary solution for enhanced security. Personal WEP 
keys are stored in an access point or an access point can get users WEP keys from a 
RADIUS server. In the case of personal WEP keys, all users have different WEP keys. 
Please see the Nokia D211 User’s Guide for further details.
