Authentication Settings
5.2.2 Authentication Settings
You can add a network automatically when a network is detected, or you can enter
setting information manually. Contact your network administrator for the
appropriate authentication information.
Note: If the network is automatically detected, you can skip step 1 and step 2.
1. To manually enter new settings, tap on Start, Settings. Tap on the Connec-
tions tab.
2. Tap on the Network Cards icon. In the Wireless tab, tap on Add new....
3. To use data encryption, tap Network Key, Data encryption (WEP
enabled). WEP (Wired-Equivalent Privacy) encryption prevents others
from accidentally accessing your network.
4. To use Shared Key authentication, tap on Network Authentication
(Shared mode). You’ll need a network key if you choose this option.
802.11b supports two subtypes of network authentication services: Open
and Shared. Under Open authentication, any wireless station can request
authentication. The station that needs to authenticate with another wireless
station sends an authentication management frame that contains the identity
of the sending station. The receiving station then sends back a frame that
indicates whether it recognizes the identity of the sending station.
Under Shared authentication, each wireless station is assumed to have
received a secret shared key over a secure channel that is independent
from the 802.11b wireless network communications channel.
5. To use an automatically assigned network key, enable the checkbox next to
The Key is provided for me automatically, or
To assign a Network key manually, disable the checkbox next to The key is
provided for me automatically, and enter the information manually.
This text box is used to specify a 5 or 13 ASCII character sequence or an
equivalent 10 or 26 Hexadecimal digit sequence that matches the active
WEP key on the access point.
