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.
