Chapter 5 Configuring the Client Adapter
Setting Security Parameters
Step 10 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 This parameter is available only if the 802.1x security option is selected.
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 11 If you want to change the value of the Group Policy Delay parameter, enter a new value or use the up
and down arrows to select a value between 0 and 65535 seconds. (Microsoft supports only values
between 30 and 600 seconds. The default value is 60 seconds.)
The Group Policy Delay parameter specifies how much time elapses before the Windows logon process
starts Group Policy, a Windows feature used by administrators to specify configuration options for
groups of users. The objective is to delay the start of Group Policy until wireless network authentication
occurs. The value that you set for this parameter goes into effect after the computer reboots with this
profile set as the active profile.
Note A Microsoft hot fix is required in order to use this parameter on computers running Windows
2000. Refer to the “Installing a Microsoft Hot Fix for Group Policy Delay” section on page 3-20
for information on obtaining and installing the hot fix.
Step 12 Click OK to save your settings and return to the Cisco Aironet Desktop Utility (Profile Management)
window.
Step 13 Refer to Chapter 6 for instructions on authenticating using PEAP (EAP-GTC).
