My P-334U 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 P-334U 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 P-334U. The WAN MAC of the P-334U can be obtained from menu 24.1.

In case the ISP does not allow you to use a new MAC, the P-334U 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 P-334U, the WAN MAC in menu 24.1 will be updated.

`Menu 2 - WAN Setup` `Link Mode= Half Duplex` `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 P-334U is attached to the cable modem to connect to the ISP, we should configure this host name in the P-334U's system (menu 1).

¡@ `Menu 1 - General Setup` `System Name= zyxel`

Key Setting:

· System Name=, The system name must be the same as the PC's computer name.

3. Your ISP checks 'User ID'

This authentication type is used by RoadRunner ISP, currently they use RR-TAS(Toshiba Authentication Service) and RR-Manager authentications. You must configure the correct 'Service Type', username and password for your ISP in menu 4.

¡@ `Menu 4 - Internet Access Setup` `ISP's Name= ChangeMe` `Service Type= RR-Toshiba Authentication Service` `Server IP= 0.0.0.0` `My Login=` `My Password= ********` `IP Address Assignment= Dynamic` `IP Address= N/A` `IP Subnet Mask= N/A` `Gateway IP Address= N/A` `RIP Direction= None` `Version= N/A` `Single User Account= Yes` `Edit Filter Set= No` `Press ENTER to Confirm or ESC to Cancel:`

Key settings:

- Service Type.......Currently, there are two authentication types that Road Runner supports, RR-TAS and RR-Manager. Choose the correct one for your local ISP.
- Server IP.............The P-334U will find the Road Runner server IP if this field is blank, otherwise enter the authentication server IP address if you know it.
- My Login Name...Enter the login name given to you by your ISP
- My Password.......Enter the password associated with the login name
- WAN IP Address Assignment...If the ISP did not assign you an explicit IP, select Dynamic, otherwise, select Static.
- IP Address & Subnet Mask & Gateway IP Address...Enter the IP address, subnet mask & gateway IP when Static Assignment is selected above.
