Configuring the Client Adapter
Step 10 Check the This is a computer-to-computer (ad hoc mode) network; wireless access points are not
used check box if you are planning to operate the client adapter in an ad hoc network.
Step 11 Check the Data encryption (WEP enabled) check box if you are planning to use static WEP.
Note
Step 12 Check the Network Authentication (Shared mode) check box if you want to use shared key (rather than
open) authentication with the access point.
Open authentication enables your client adapter, regardless of its WEP settings, to authenticate and
attempt to communicate with an access point.
Shared key authentication enables your client adapter to communicate only with access points that have
the same WEP key. Cisco recommends that shared key authentication not be used because it presents a
security risk.
Step 13 Follow the steps below to enter up to four WEP keys, if you are planning to use static WEP.
a. Obtain the WEP key for the access point (in an infrastructure network) or other clients (in an ad hoc
network) from your system administrator.
b. Tap the Modify WEP Key button. The Wireless (WEP) Key Settings screen appears (see

which include 0-9, A-F, and a-f.
ASCII text WEP keys are not supported on the Cisco Aironet 1200 Series Access Points, so
you must select the Hexadecimal digits option if you are planning to use your client adapter
with these access points.
