Introduction

The purpose of this document is to guide you in using wireless LAN (WLAN) connections with your Nokia 9300i. Typical situations in which you might use WLAN with Nokia 9300i include, but are not limited to, downloading e-mail 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 9300i supports the following WLAN features:

• IEEE 802.11g and IEEE 802.11b WLAN standards

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

• For interoperability with older WLAN networks, Nokia 9300i also supports the legacy static WEP security and dynamic WEP security

Nokia 9300i does not support the IEEE 802.11a WLAN standard.

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.

Defining WLAN connection settings

This chapter discusses the WLAN settings in Nokia 9300i. 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

Defining WLAN connection settings

settings in the WLAN IAP include the network name (SSID), the WLAN security mode, and the security mode specific security settings.

It is not always necessary to pre-configure the IAP settings, as the user can select the Easy WLAN Internet Access Point. The Easy WLAN IAP allows the user to connect to newly discovered WLAN networks for which there is no pre-configured IAP. In WLAN access point usage, the Easy WLAN IAP can be used for connections to open networks (security mode "None") that use HTTP based logon.

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.

Creating a WLAN Internet Access Point for a WLAN access point

To create a new Internet Access Point, select Desk→

Tools

→ Control Panel→ Connections→ Internet setup.

When the list of existing IAPs is shown, press New to create a new one. If there are existing IAPs, the setup asks

Page 5

you if you want to use of of them as a basis for the new IAP.

1 Define the following settings:

• Internet settings name — Type any name you want for

the IAP; “Operator X WLAN service”, for example.

• Network ID — Select the network ID for the

connection. In most cases this can be Internet (the other option is Default GPRS network, which you probably already have settings for).

• Internet settings type — Select Wireless LAN.

Press Next to proceed.

2 Define the following settings:

• Network mode — Select Infrastructure to be able to

connect to WLAN networks through a WLAN access point. The other option is Ad hoc, which is discussed later in this chapter.

• Network name — Enter the exact (case sensitive)

network name (SSID) of the WLAN network. 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.

Press Next to proceed.

3 Select the WLAN security mode. Nokia 9300i supports

the following WLAN security modes:

• 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. Nokia uses the latter notation. Both notations are equivalent at WLAN protocol level and fully interoperable. Nokia 9300i supports 40 (64) bit and 104 (128) bit WEP key lengths.

Defining WLAN connection settings

Page 6

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.

When this security mode is selected and you press

Next, the following dialog will be shown. Configure

the WEP key by selecting its number, length and type and then entering the key.

Defining WLAN connection settings

Note: A WEP key can be entered in hexadecimal (HEX) or text (ASCII) format. It is important that the same notation is used both in the access point and the Nokia 9300i. A 104 bit WEP key is the same as a 128 bit WEP key, and you should enter 26 characters if you are using the HEX format, or 13 characters if you are using the ASCII format. Similarly, a 40 (64) bit WEP key requires 10 (HEX) or 5 (ASCII) characters.

• 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 9300i 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 9300i. As required by the Wi-Fi specifications, WEP ciphering is not allowed in this mode, so either Temporal Key Integrity Protection (TKIP) or AESCCMP is used as the ciphering method. When this security mode is selected and you press

Next, the following dialog will be shown. Select EAP

in order to use Extensible Authentication Protocol (EAP) based logon, or select Pre-shared key to use a master password, which you must then enter.

user uses only one EAP method, so in most cases only one EAP method should be enabled in this dialog.

Press Next to proceed. If you do not need to configure any advanced settings, press Finish to save the settings of your new IAP. Otherwise, press Advanced.

Note: If you selected the 802.1x or the WPA/EAP security mode, you have to access the advanced settings to configure EAP settings.

4 In the advanced settings, press Menu to change to the

802.1x page (in 802.1x mode) or WPA page (in WPA/

WPA2 mode), and make sure that the WPA mode is set to EAP, as it should by default. This means that EAP based logon will be used. You can also configure the device to use WPA2 only. This disables the use of TKIP and mandates the more secure AES-CCMP ciphering algorithm. When this option is enabled, Nokia 9300i is not able to join WPA networks and WPA/WPA2 mixed mode networks. Press Menu again to change to the EAP page and configure the EAP settings. Select the EAP methods that are allowed in this mode by moving up and down in the list and pressing Disable or Enable. Typically, the

5 In the advanced settings, press Menu to change to the

IP configuration page and set the IP address and

parameters, if necessary. In public wireless LAN networks DHCP is typically used, so the default value

Yes for Auto retrieve IP should be used there. For the

IPv6 DNS mode, you can select one of three alternatives: DHCP, Manual or Well known. If you select

Manual, you need to type the IP addresses of the

primary and secondary DNS servers.

6 In the advanced settings, press Menu to change to the

Proxies page and configure the HTTP and HTTPS proxy

settings, if necessary. If a web proxy needs to be used, select the protocol (HTTP or HTTPS), set User proxy

server to Yes, type the IP address or domain name of

the Proxy Server, type the Port Number (for example 8000 or 8080). You can use the No proxy for field to define the domains for which the HTTP or HTTPS proxy is not needed.

7 Press Done and press Finish to save the settings of

your new IAP.

Simultaneous Bluetooth usage, if it is allowed. Then you

must remove the battery, reinsert it and switch on the device before browsing the Web again. This also turns off WLAN power saving in your device.

• The WLAN icon sometimes appears different: the WLAN network icon “W” in the upper left corner of the screen has the following implications for troubleshooting:

1 If the icon is not displayed at all, a WLAN connection

WLAN connection is working normally and the problem probably lies with TCP/IP.

3 If background scanning is turned on and the “W”

icon is displayed without any border graphics (see the image below), it means that a WLAN network is available (that is, there is network coverage). It does not indicate that a WLAN connection is active and can be used to transfer data.

• Wrong IP address: if the “W” icon is displayed and surrounded by a box or lock graphic but data cannot be transferred, the IP address may be defined incorrectly. To check the IP address of your WLAN connection, select Desk

2 Try using manually configured IP settings instead of

DHCP. Notice that this requires that you have acquired the appropriate IP settings for the particular network. You should request them from the network administrator.

• Wrong proxy settings: if you cannot browse the Web even though the WLAN connection is working and the IP settings seem to be correct, check that the HTTP/ HTTPS proxy settings are defined correctly in the Internet Access Point settings.

• Problems with the WEP security mode: if you encounter these, check that the WEP keys have been entered in the correct format (ASCII vs. HEX) and have the right number of characters. ASCII WEP keys are also case sensitive; check that you have not confused any upper or lower case letters in the key. Incorrect WEP keys may cause a situation where Nokia 9300i is able to associate with a WLAN network (the

“W” icon with a box graphic is visible) but no data can be transferred. Also remember to check that the WEP authentication mo de is co rr ect. I n t he ac ce ss point it may be called, for example, “WEP authentication”, “shared-key authentication” or “Wi-Fi security mode”.

• Poor signal quality: to check the signal quality of your WLAN connection, select Desk

Panel

If the signal quality is weak or even moderate, you may encounter connection problems. Try again nearer the access point.

• Wrong security mode: if the “W” icon is displayed but not surrounded by a box or lock graphic, the configured security mode may not be the right mode. To check the security mode that the network uses, select Desk

→ Control Panel→ Connections→ Wireless

• Problems with the WPA/WPA2 or 802.1x security mode: if you encounter these, check the following:

→ Tools→ Control

→

1 Check that the WPA mode is the right one (pre-

shared key or EAP).

2 Check the pre-shared key.

Page 15

3 Check that all EAP types that are not needed are

disabled.

4 Check that EAP type settings are correct (passwords,

user names, certificates, etc.).

• Problems with access point configuration: if you encounter these, check the following:

1 Many WLAN access points contain proprietary

“Turbo” mode’s claiming to enhance data rates. These functionalities should be disabled from the IAP if there is any reason to believe that they are causing problems to legacy WLAN terminals (including Nokia 9300i).

2 Many interoperability problems are solved by

updating the IAP firmware to the latest version.

• Finally...: remember that all Wi-Fi certified devices are unfortunately not compatible, even if they are supposed to be.
