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 the 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 Prestige supports to clone the MAC from the first PC the ISP installed to be its WAN MAC. 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 and used for the ISP's authentication.
Key settings:
Assigned By, Choose 'IP address attached on LAN'.

2. Your ISP checks the 'Host Name'
Some ISPs take advantage of the 'host name' message in a DHCP packet such as @home to do the
authentication. When first installing, the ISP's tech people configure the host name as the 'Computer
Name' of the PC in the 'Networking' settings. When the Prestige is attached to the cable modem to
connect to the ISP, we should configure this host name in the Prestige's system (menu 1).
