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

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.

Menu 2 - WAN Setup

MAC Address:

Assigned By= IP address attached on LAN

IP Address= 192.168.1.33

Key settings:

 Assigned By=, Choose 'IP address attached on LAN'.

 IP Address=, Enter the IP address of the PC which is installed by the ISP at the first

installation.

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).
