Trouble Shooting

Unable to Get WAN IP from ISP

My ZyXEL Device can not get an IP address from the ISP to connect to the Internet, what can I

do?

Currently, there are various ways that ISPs control their users. That is, the WAN IP is provided only when

the user is checked as an authorized user. The ISPs currently use three ways:

1. Check if the 'MAC address' is valid

2. Check if the 'Host Name' is valid, e.g., @home

3. Check if the 'User ID' is valid, e.g., RR-Toshiba Authentication Service, RR-Manager

Authentication Service

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 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.
