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 ISP’s authenticates users.
1.
Check if the modem’s 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 ISP’s 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.
You can set the Prestige to copy the MAC address of the computer whose MAC address is authorized by the
ISP. The Prestige will use the copied MAC address as its WAN MAC address.
In SMT menu 2, enter the computer MAC address. The Prestige will use the copied MAC address as its WAN
MAC address and update SMT menu 24.1.
