or video files, a significant portion of the shared bandwidth is used thus slowing down access for other users in the same neighborhood.

Most independent Internet Service Providers today connect to the Internet using a single 1.5 Mbps "T1" telephone line. All their subscribers share that 1.5 Mbps bandwidth. Cable companies connecting to the Internet backbone using a T1 limit their subscribers to an absolute maximum of 1.5 Mbps.

To create the appearance of faster network access, ISPs store or "cache" frequently requested web sites and Usenet newsgroups on a server in the central office (CO). Storing data locally will remove some of the bottleneck at the backbone connection.

How fast can they go? Theoretically, they can receive data at speeds up to 30 Mbps. In the real world, with cost conscious cable companies running the systems, the speed will probably fall to about 1.5 Mbps.

My Prestige cannot obtain a WAN IP address from the ISP to connect to the Internet, what should I do?

There are various ways your ISP controls user access and login. Once a user has successfully logged into, the ISP will provide the WAN IP address to the user.

The following lists the methods ISPs authenticates users.

1.Check if the modems MAC address' is valid.

2.Check if the host name is correct. The host name is usually the text after the @ sign. For example, @home

3.Check if the user ID is valid. This is commonly used with the RR-Toshiba Authentication and RR-Manager Authentication services.

If you are not able to get a WAN IP address from your ISP, check which authentication method your ISP uses and configure the settings on the Prestige. The following sections describe how you can solve this problem.

1. If your ISP checks the MAC address

Some ISPs checks the user device (usually a computer) MAC address before assigning a WAN IP address. If the MAC address matches one on the ISPs system, the ISP sends an IP address to the user device and allows Internet access. However, if the user connects another computer with a different MAC address directly to the modem, the ISP discards any DHCP discovery packets from the un-authorized MAC address and no IP address is assigned.
