Chapter 5 Configuring the Client Adapter
Setting Security Parameters
Step 8 Perform one of the following to set the Allow Association to Mixed Cells parameter, which indicates
whether the client adapter can associate to an access point that allows both WEP and non-WEP
associations:
• Check the Allow Association to Mixed Cells check box if the access point to which the client
adapter is to associate (or the VLAN to which the client will be assigned) has WEP set to Optional.
Otherwise, the client is unable to establish a connection with the access point.
• Uncheck the Allow Association to Mixed Cells check box if the access point to which the client
adapter is to associate (or the VLAN to which the client will be assigned) does not have WEP set to
Optional. This is the default setting.
Note For security reasons, Cisco recommends that WEP-enabled and WEP-disabled clients not be
allowed in the same cell because broadcast packets are sent unencrypted, even to clients running
WEP. However, you can enable VLANs on the access point to separate WEP-enabled and
WEP-disabled clients.
Step 9 Click OK to save your settings and return to the Cisco Aironet Desktop Utility (Profile Management) window.
Enabling WPA/WPA2 Passphrase
Follow the steps below to enable WPA/WPA2 passphrase (also known as WPA/WPA2 pre-shared key) for
this profile.
Note To use WPA passphrase, client adapters must use the software included in Install Wizard 1.0 or later and
access points must use Cisco IOS Release 12.2(11)JA or later. To use WPA2 passphrase, client adapters
must use the software included in Install Wizard 2.0 or later and access points must use Cisco IOS
Release 12.3(2)JA or later.
Step 1 Choose WPA/WPA2 Passphrase on the Profile Management (Security) window.
Step 2 Click Configure. The Define WPA/WPA2 Pre-Shared Key window appears (see Figure 5-6).
