• Password — Type your password for the configuration server. Confirm it in the Confirm password field. Contact your serviceprovider or system administrator for the correct password.• HTTP authentication — Select Yes if you need to send your user name and password to the HTTP server. In the HTTPauthentication dialog, enter your user name and password, and press Done.To edit the configuration profile settings, select the profile, and press Edit.To delete a profile, select the profile, and press the backspace key.Tip: If you have deleted or modified the predefined PC Suite profile, you can restore it by pressing Menu, and selectingTools > Reset PC Suite profile.Data connectionsThis device supports packet data (GPRS), high-speed data calls (HSCSD), GSM data calls, and wireless LAN connections.Wireless local area network (wireless LAN)There may be restrictions on using wireless LAN in some locations. Check with your local authorities or service provider.Features using wireless LAN, or allowing such features to run in the background while using other features, increase the demandon battery power and reduce the battery life.Your device is approved for use in a wireless LAN. You can use wireless LAN to send and receive e-mail, and connect your deviceto the Internet.Your device supports the following wireless LAN features:• IEEE 802.11b and IEEE 802.11g standards• Operation at a frequency of 2.4 GHz using direct sequence spread spectrum (DSSS) radio technology• Wired equivalent privacy (WEP) data encryption• Wi-Fi protected access (WPA and WPA2)Note that the WEP and WPA/WPA2 functions can be used only if they are supported by the network.If you move the device to another location within the wireless LAN and out of range of a wireless LAN access point, the roamingfunctionality can automatically connect your device to another access point that belongs to the same network. As long as youremain within range of access points that belong to the same network, your device can stay connected to the network.Tip: A wireless LAN connection is established when you create a data connection using a wireless LAN Internet accesspoint. The active wireless LAN connection is ended when you end the data connection.Your device enables different types of communication in a wireless LAN. There are two operating modes to choose from:infrastructure and ad hoc.• The infrastructure operating mode allows two kinds of communication: wireless devices communicate with each otherthrough a wireless LAN access point or wireless devices communicate with a wired LAN device through a wireless LAN accesspoint.The advantage of the infrastructure operating mode is that you can have more control over network connections becausethey pass through an access point. A wireless device can access the services that are available in a regular wired LAN: companydatabase, e-mail, the Internet, and other network resources, for example.• With third party applications, you can send and receive data directly with each other in the ad hoc operating mode, forexample, to print. No wireless LAN access point is required. Simply make the necessary configurations and startcommunicating. Ad hoc networking is easy to set up, but communication is limited to devices that are within range.See "Setting up an Internet access point for a wireless LAN," p. 69.See "Setting up an ad hoc network," p. 83.Packet data (general packet radio service, GPRS)GPRS enables wireless access for mobile phones to data networks (network service). GPRS uses packet data technology whereinformation is sent in short bursts of data over the mobile network. The benefit of sending data in packets is that the networkis occupied only when sending or receiving data. As GPRS uses the network efficiently, it allows for quick data connection setup and fast data transmission speeds.You must subscribe to the GPRS service. For availability and subscription to GPRS, contact your network operator or serviceprovider.Enhanced GPRS (EGPRS) is similar to GPRS, but it enables faster connection. For more information on the availability of EGPRSand data transfer speed, contact your network operator or service provider. Note that when you have selected GPRS as a databearer, the device uses EGPRS instead of GPRS if this is available in the network.Note that during a voice call, you cannot establish a GPRS connection, and an existing GPRS connection is put on hold.C o n n e c t i v i t yCopyright © 2005 Nokia.
