your ISP or select AUTO.

MAC Clone: When you cannot access the Internet after finishing other settings here except this option, consider

whether it’s the matter of the MAC address of your computer. Clicking Clone MAC button copies the MAC address of

your computer to the modem router.

MTU: Keep the default value unless you are sure it is necessary for your ISP connection.

Dial on demand: Connect to ISP only when there is traffic transmission. This saves your broadband Internet service bill.

will be changed to the device's WAN IP address. Only change the default settings if necessary.

Enable PPP Debug Mode: Only enable this feature if supported by your ISP.

Knowledge Expansion

1. MAC Clone: Many broadband ISPs restrict access by allowing traffic only from the MAC address of your broadband

modem, but some ISPs additionally register the MAC address of your computer when your account is first opened. If so,

only by cloning the MAC address of your computer can you access the Internet through the modem router.

2. MTU: Short for Maximum Transmission Unit, the largest physical packet size, measured in bytes, which

a network can transmit. Any messages larger than the MTU are divided into smaller packets before being sent. The

default MTU is 1492 bytes. For some ISPs, you might need to change the MTU. This is rarely required, and should not

be done unless you are sure it is necessary for your ISP connection.

 To configure the Default Gateway interface, select the interface that you want to configure with the WAN gateway

address in Available Routed WAN Interfaces box and move it into Selected Default Gateway Interfaces box. The

default setting is recommended. Then click Next.
