3 In the Security/Network window, WLAN Service Area displays the name of the 

wireless network with which the wireless PC client can associate. You can change 
this setting as follows:

Check this box to associate the client automatically to the WLAN service area with 
the best signal strength. This is recommended.

First uncheck the Attach to any WLAN Service Area automatically box. Then, you 
can either enter the name of a service area (up to 32 characters long), or select 
from recently used WLAN service areas or from all available WLAN Service Areas 
within the range of the client. 

You can set the level of security used to protect the network communications 
between the client and the access point from interception by unintended 
recipients. The security settings must match those that the network administrator 
has set up on the network. Some security levels require you to supply encryption 
settings. The levels of security are:

To maintain wireless association between clients and access points, follow these 
guidelines:

■

The security setting on the client and the access points must match exactly.

■

For 40-bit Shared Key (Wi-Fi) security, the encryption settings on the client and 
the access point must match exactly.

■

For 128-bit Dynamic Security Link security, the user name and password on the 
client and the access points must match exactly.

40-bit Shared Key (Wi-Fi) security requires you to set up encryption keys. Your 
network administrator sets up encryption keys for the wireless network and gives 
you an encryption string or hexadecimal keys.

■

An encryption string is a string of characters between 8 and 64 characters 
long. The string can be any combination of letters and numbers and is case 
sensitive. The encryption string can be used only with other 3Com 11 Mbps 
wireless PC Cards and access points. 

No Security (Open System)

No encryption is used. The network communications could 
be intercepted by unintended recipients.

40-bit Shared Key (Wi-Fi)

This option encrypts the wireless transmissions to protect 
your data and is compatible with other Wi-Fi certified 
wireless PC clients and access points from other 
manufacturers.

128-bit Dynamic Security Link

This option can only be used with a 3Com 11 Mbps 
Wireless LAN Access Point. It is the highest level of security, 
in which you must enter a user name and password. These 
must match the user name and password set up by the 
administrator on the access points with which you 
associate. Each network session automatically creates a 
unique, one-time, 128-bit encryption key. You never have 
to enter a key.
