Introduction Introduction 3 Using WLAN wizard Using WLAN wizard The WLAN wizard helps you to connect to a wireless LAN. The WLAN wizard shows the status of your wireless LAN connections and network searches in the active standby mode. To view the available options, scroll to the row showing the status, and press the scroll key. Depending on the status, you can start the web browser using a wireless LAN connection, disconnect from a wireless LAN, search for wireless LANs, or set network scanning on or off. If wireless LAN scanning is off and you are not connected to any wireless LAN, WLAN scanning off is displayed in the active standby mode. To set scanning on and search for available wireless LANs, scroll to the status, and press the scroll key. To start a search for available wireless LANs, scroll to a status, press the scroll key, and select Search for WLAN. To set wireless LAN scanning off, scroll to a status, press the scroll key, and select Switch WLAN scan off. When you select Start Web browsing, the WLAN wizard automatically creates an internet access point (IAP) for the selected wireless LAN. The IAP can also be used with other applications requiring wireless LAN connection. If you select a secured wireless LAN network, you are asked to enter the relevant passcodes. To connect to a hidden network, you must enter the correct hidden service set identifier (SSID). You can also start the WLAN wizard separately to get more information on wireless LANs within range. Select Menu > Connect. > WLAN wiz.. Found networks are displayed. Scroll to the desired network, select Options, and from the following: · Start Web browsing or Cont. Web browsing -- Start or continue browsing the web using the IAP of the wireless LAN. · Disconnect WLAN -- Disconnect the active connection to the wireless LAN. · Refresh -- Update the list of available wireless LANs. · Details -- View the details of the wireless LAN. · Define access point -- Create an internet access point without starting the web browser. 4 Copyright © 2007 Nokia.

Using encryption reduces the risk of unauthorized access to your data. 5 Defining WLAN connection settings Defining WLAN connection settings This chapter discusses the WLAN settings in Nokia E65. Special focus is on the selection of the WLAN security mode. Different connectivity settings, including GPRS, WLAN and other technologies, are organised 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. Creating a WLAN Internet Access Point for a WLAN access point 1 Select Menu > Tools > Settings > Connection > Access points. 2 The list of existing access points is shown. Press Options > New access point to create a new Internet 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 6 Copyright © 2007 Nokia. All rights reserved. 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, · 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 E65 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 E65. · 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. Copyright © 2007 Nokia. All rights reserved. Defining WLAN connection settings the secure connection icon is not displayed. 7 Defining WLAN connection settings · EAP plug-in settings -- If you selected EAP, you must also define these settings. See page 9 for more information. · TKIP encryption -- To enable TKIP encryption, based on transient keys changed often enough to prevent misuse, select Allowed. All devices in the wireless LAN must either allow or prevent the use of TKIP encryption. If you selected 802.1x 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. Note: 802.1x authenticates and authorises devices to access a wireless network, and prevents access if the authorisation process fails. If you selected WEP as the WLAN security mode, define the following in WLAN security sett.: · WEP key in use -- Select which WEP key is used (#1­#4). · Authentication type -- Select Open or Shared. · WEP key settings -- The remaining settings are defined here: WEP encryption -- Select the desired WEP encryption key length. Supported options are 64 and 128 bits. The more bits there are in the key, the higher the level of security. WEP keys consist of a secret key and a 24-bit initialisation vector. For example, some manufacturers refer to the 104-bit key as a 128-bit key (104+24). Both keys offer the same level of encryption and are therefore interoperable. · EAP plug-in settings -- If you selected EAP, you must also define these settings. See page 9 for more information. 8 Copyright © 2007 Nokia. All rights reserved. Wireless LAN, select Back to save the settings of your WLAN IAP and exit, or Options > Advanced settings to define the following advanced settings: · IPv4 settings -- Enter the device IP and name server addresses for IPv4 Internet protocol. · IPv6 settings -- Select or enter the name server addresses for IPv6 Internet protocol. · Proxy serv. address -- Enter the proxy server address. · Proxy port number -- Enter the proxy server port number. Proxy servers are intermediate servers between a browsing service and its users, which are used by some service providers. These servers may provide additional security and speed up access to the service. Note: The settings available for editing may vary. Contact your service provider for more information. Note: Wired equivalent privacy (WEP) encryption method encrypts data before it is transmitted. Access to the network is denied to users who do not have the required WEP keys. When WEP security mode is in use, if your device receives a data packet not encrypted with the WEP keys, the data is discarded. In an Ad-hoc network, all devices must use the same WEP key. Modifying EAP settings The extensible authentication protocol (EAP) plug-ins are used in wireless networks to authenticate wireless devices and authentication servers, and the different EAP plug-ins make possible the use of various EAP methods (network service). To use an EAP plug-in when you connect to a WLAN using t ...
