Prestige 2304 Support Notes

Currently, there are various ways that ISPs control their users. That is, the WAN IP is provided only when the user is checked as an authorized user. The ISPs currently use three ways:

1.Check if the 'MAC address' is valid

2.Check if the 'Host Name' is valid, e.g., @home

3.Check if the 'User ID' is valid, e.g., RR-Toshiba Authentication Service, RR-Manager Authentication Service

If you are not able to get the Internet IP from the ISP, check which authentication method your ISP uses and troubleshoot the problem as described below.

1. Your ISP checks the 'MAC address'

Some ISPs only provide an IP address to the user with an authorized MAC address. This authorized MAC can be the PC's MAC which is used by the ISP for authentication. So, if a new network card is used or the Prestige is attached to the cable modem directly, the ISP will reject the DHCP discovery from this MAC, thus no IP is assigned by the ISP.

The problem can be simply solved if the ISP allows you to use a new MAC, and you just tell them the WAN MAC of the Prestige. The WAN MAC of the Prestige can be obtained from menu 24.1.

In case the ISP does not allow you to use a new MAC, the Prestige can clone the MAC from the first PC you installed as the WAN MAC and send it to the ISP. To clone the MAC from the PC you need to enter that PC's IP in menu 2. Once the MAC is received by the Prestige, the WAN MAC in menu 24.1 will be updated.
