Preparing Clients
MSS uses 802.1X for access to secure (encrypted) 
SSIDs. For a client to access an encrypted SSID, 802.1X 
must be configured on the client. Depending on the 
type of encryption used for the SSID, additional 
configuration on the client might be required. 
The following sections describe how to configure a 
Windows XP (Service Pack 2) client for access to an 
unencrypted (clear) or encrypted SSID. The exact 
procedure and the options that are supported depend 
on the Windows version installed on the client and 
might also depend on the wireless adapter card. See 
the Release Notes for 3Com Mobility System Software 
for additional client recommendations and a list of 
supported wireless adapters.
To configure a Windows XP SP2 client to access an 
SSID and use dynamic WEP encryption:
