P2302R-P1C Support Notes
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.

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).
