This is the Internet version of the user's guide. © Print only for private use. GPRS Advanced tabs Log in The settings on this tab deal with IP and DNS addresses. The DNS address uniquely identifies your Internet Service Provider (ISP)'s computers, which your P910i uses to connect to the Internet. Your P910i can normally fetch these addresses automatically from most ISPs. If, after setting up an Internet account, you cannot connect to the Internet and you suspect these addresses are incorrect, ask your ISP for their primary and secondary DNS addresses. An IP address consists of four 3-digit boxes and valid input is between 000 and 255 in each box. Proxy A proxy server is a computer connected between your P910i and the computer you communicate with. This arrangement can be used for connections to Remote Sync servers, or within a company network. If this setting is needed, your company's Information Services department or Remote Sync provider must give you instructions. Other If your ISP supports Point to Point Protocol (PPP) extensions, you can select the Enable PPP extensions check box. PPP extensions allow your P910i to provide features such as encryption, which increases the security of your Internet connection. GPRS Advanced tabs Authentication is used by some network operators to identify the mobile phone connecting to their GPRS network. There are different methods, or protocols, for doing this. Normal: PAP (Password Authentication Protocol). The user's username and password are transmitted over the network in an unencrypted form. Secure: CHAP (Challenge Handshake Authentication Protocol). The user's username and password are never transmitted over the network. None: No authentication is required by the network operator. QoS Check with your network operator before changing any of the QoS (Quality of Service) settings. The settings Precedence, Delay, Peak rate, and Mean rate are all by default set to Subscribed, which means that your operators default QoS (Quality of Service) values will apply. Reliability is set as Class 3 by default. New Dial-Up or High-Speed Dial-Up account Your Internet Service Provider (ISP) supplies you with your User name, your Password, and their Phone number, which your P910i dials to connect to the Internet. If you have a High-Speed DialUp account with your network operator you can increase the speed of your connection by making settings on the Speed tab under Advanced. Control panel 157
