ZyXEL Device 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 ZyXEL Device. The WAN MAC of the ZyXEL Device can be obtained from menu
24.1.
In case the ISP does not allow you to use a new MAC, the ZyXEL Device 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 ZyXEL Device, the WAN MAC in
menu 24.1 will be updated.

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 ZyXEL Device is attached to the cable modem to
connect to the ISP, we should configure this host name in the ZyXEL Device's system (menu 1).
