Configuration and Management
2.3 Configuration Wizard
The Configuration Wizard guides you step by step through the basic setup
of the mobile network connection and optionally for the Wireless LAN
access point.
Note: Throughout the wizard web-pages, only enter details that you have
received from your service provider and leave other fields empty.
Click the Configuration Wizard… button on the Overview page to start the
wizard.
2.3.1 Internet Access
The first part of the Configuration Wizard includes Internet authentication
details. Depending on the current Internet service setup, the requests on
authentication may differ. The service provider provides the required
authentication details.
Figure 7 - Internet Access: SIM Authentication page
2.3.1.1 SIM Authentication
The service provider provides you with a SIM card. This SIM card contains
information about the subscription and is normally protected by a PIN
(Personal Identification Number) and a PUK (Personal Unblock Key) code.
1/1551-CRH 102 167 Uen Rev F 2008-07-09 13

Configuration and Management
Normally, you have to enter the PIN to activate the Ericsson W21 data
services. In some cases however, authentication is not required and it is
possible to use the services without entering any PIN.
Type the PIN in the “PIN” field.
Thereafter, you can select the “Remember my PIN” check box. This makes
SIM authentication automatic and you will not have to enter the PIN in case
of a system restart.
Click Next to proceed.
2.3.1.2 APN
An APN (Access Point Name) is a reference to the Internet access point on
the service provider’s network. It usually has the format
<name.service_provider.country>. Different APNs for the GSM (2G) and
UMTS (3G) networks may be required.
Figure 8 - Internet Access: APN page
Check the “Auto APN” option if you have not received any APN(s) from
your service provider. In this case the APN is automatically configured
based on information on the SIM card.
If you have received APN(s) from your service provider, type the
information in the corresponding “APN (2G)” and ”APN (3G)” fields.
Click Next to proceed.

Configuration and Management
2.3.1.3 PPP User Authentication
The PPP (Point-to-Point Protocol) Internet mode may require individual
user authentication.
Note: If you have not received any PPP Authentication details from your
service provider, leave the fields empty and click Next .
Figure 9 - Internet Access: PPP User Authentication page
Type the authentication details you have received in the “PPP user name”
and “PPP password” fields and select the appropriate “Authentication
Protocol”.
Click Next to proceed.
2.3.2 Wireless LAN Access
The second part of the Configuration Wizard includes configuration of the
Wireless LAN (WLAN). A Wireless LAN is a local network that
communicates through wireless connections.
Note: The wireless setup typically requires configuration of both the
Ericsson W21 and the wireless clients. For more information about
configuring wireless clients, see – Wireless LAN Settings.3.2
1/1551-CRH 102 167 Uen Rev F 2008-07-09 15

Configuration and Management
2.3.2.1 Enable the Wireless LAN
The Ericsson W21 is a WLAN Access Point (AP) for the local network
providing wireless client(s) with Internet and LAN access.
Figure 10 - Wireless LAN: WLAN Access Point page
To enable connection of one or more wireless devices to the Ericsson W21,
select the “Enable WLAN” check box.
Click Next to proceed.
Note: The WLAN interface will not be activated until the complete
configuration details are entered.
If you are not going to set up any Wireless LAN, just leave the box
unchecked and click Next . The last page of the wizard, where you can
review and confirm your settings, is displayed:

Configuration and Management
Figure 11- Configuration Wizard Confirmation page
To confirm the settings and close the Configuration Wizard, click the
Finish button.
You can use the Previous button to go back to previous pages and check
your settings and/or make changes. If you click the Cancel button, the
Configuration Wizard closes and no changes are saved.
2.3.2.2 Region
To make sure the Ericsson W21 operates on correct radio frequencies
according to local regulations, you have to state in which region you reside.
Figure 12 - Wireless LAN: Region page
1/1551-CRH 102 167 Uen Rev F 2008-07-09 17

Configuration and Management
Select your country domain from the “Region” drop-down list.
Click Next to proceed.
2.3.2.3 Channel Selection
The maximum number of regulatory channels to use for wireless
communication is 13. Available channels depend on which region that was
selected in the previous step. You can select one of the available channels
in the “Channel” drop-down list, or let the Ericsson W21 automatically
select a channel (“Auto”). By selecting “Auto” the radio will automatically
scan each valid channel and choose the one with least interference.
Figure 13 - Wireless LAN: Radio Channel page
Select either “Auto” (recommended) or a specific channel number from the
“Radio channel” drop-down list.
Click Next to proceed.
2.3.2.4 Network Name
All devices on the local wireless network share a common Service Set
IDentifier (SSID) or network name. This name is required to establish
connection between the Ericsson W21 and the wireless client(s), and to
distinguish the wireless network from any other(s) that may be in use
nearby. Only devices configured with the same network name as the one
set on the Ericsson W21 can obtain access to it.
