Introduction

The purpose of this document is to guide you in using wireless LAN (WLAN) connections with your Nokia E61. Typical situations in which you might use WLAN with Nokia E61 include, but are not limited to, downloading email with attachments, browsing the web and downloading files, connecting to company network, connecting to a WLAN-capable laptop computer, and sending a document to a WLAN-connected printer. WLAN connections can be used both in public situations, such as when waiting at an airport or staying at a hotel, and in private wireless networks at your office or home.

Nokia E61 supports the following WLAN features:

• IEEE 802.11g and 802.11b WLAN standards

• Wi-Fi Protected Access 1.0 and 2 (WPA/WPA2)

• For interoperability with older WLAN networks, Nokia E61 also supports the legacy static WEP security and dynamic WEP security

Note: The typical transmission range of WLAN connections is limited from 30 meters in indoor spaces to 100 meters in open spaces. The range of wireless devices can be affected by metal surfaces, solid high-density materials and obstacles in the signal path.

Introduction

Defining WLAN connection settings

This chapter discusses the WLAN settings in Nokia E61. Special focus is on the selection of the WLAN security mode.

Different connectivity settings, including GPRS, WLAN and other technologies, are organized in so called Internet Access Points (IAPs) in your device. For WLAN access point usage, a WLAN IAP can be created. The advantage of using WLAN access point is that you have more control (particularly regarding security) over network traffic because it passes through the access point, and that you can use any resources in the wired network that the WLAN access point is connected to. The most important settings in the WLAN IAP include the network name (SSID), the WLAN security mode, and the security mode

specific security settings.

It is also possible for WLAN devices to communicate directly with each other without any WLAN access points. This is done via ad hoc networks, which are established by a single user and others can then join in. Ad hoc connections are easy to set up, but they are limited to devices within the wireless transmission range. You can use ad hoc WLAN connections to print a document in your device to a compatible printer, for example.

access point. To use an existing access point as a basis for the new one, select Use existing settings. To start with an empty access point, select Use default settings.

3 Define the following settings:

• Connection name — Type a descriptive name for the

Internet access point, such as My WLAN Internet.

• Data bearer — Select Wireless LAN.

• WLAN netw. name — To enter the service set identifier

(SSID), that is, the name that identifies the specific wireless LAN, select Enter manually. The name must be exactly the same as in your Wi-Fi router. If you do not enter the SSID here, you are not able to connect to networks that use a hidden SSID. To select the network from the wireless LANs in range, select Search for netw..

• Network status — Select Hidden if the network you are

connecting to is hidden, or Public if it is not hidden.

• WLAN netw. mode — Select Infrastructure. In this

mode, devices can communicate with each other and

with wired LAN devices through a wireless LAN access point.

• WLAN security mode — You must select the same

security mode that is used in the wireless LAN access point. If you select WEP (wired equivalent privacy),

802.1x, or WPA/WPA2 (Wi-Fi protected access), you

must also configure the relevant additional settings as described in step 4. The available modes are:

• None — This security mode is commonly used with

HTTP based logon. User authentication is performed at a higher layer using a HTML login page.

• WEP — This security mode is supported for

compatibility with IEEE 802.11 Wired Equivalent Privacy (WEP) networks. Pre-configured static WEP keys are required for this mode. There are two notations in use in the WLAN industry for the WEP key length representation, which sometimes makes things a bit confusing. The reason is that WEP key has a 24 bit common part and some vendors count this as being part of the key length, while some vendors do not. Both notations are equivalent at WLAN protocol level and fully interoperable.

Note: The WEP mode provides a lower level of security than the Wi-Fi Protected Access (WPA) mode. If you use the WEP mode, you should change the key regularly. In the WEP mode,

the secure connection icon is not displayed.

• 802.1x — This security mode is provided in order

to support the legacy Dynamic WEP system, and to support networks that are migrating from Dynamic WEP to Wi-Fi Protected Access (WPA/ WPA2). In this mode, Nokia E61 is able to join both dynamic WEP and WPA networks. Dynamic WEP refers to the fact that WEP keys are not static or pre-configured, but they are dynamically generated as part of the Extensible Authentication Protocol (EAP) authentication procedure. If WLAN access points support WPA, then it is recommended to use the WPA/WPA2 security mode instead of this mode.

• WPA/WPA2 — The Wi-Fi Protected Access (WPA/

WPA2) security mode provides the highest level of security among the WLAN security modes of Nokia E61.

• Homepage — Enter the Web address of the page you

want to display as a home page when you use this access point.

Note: The settings available for editing may vary.

4 If you selected WPA/WPA2 as the WLAN security mode,

define the following in WLAN security sett.:

• WPA mode — Select EAP if you want to use an EAP

module for authentication. If you select Pre-shared

key, type the password (also called a master key) in

the field. Note that the same key must be entered in the wireless LAN access point.
