ENABLING MAC ADDRESS SPOOFING
Some ISPs require you to have a single MAC address to connect to the Internet. (The MAC address is a unique hardware address assigned to each PC; MAC addresses are a
43
character code separated by dashes or colons.) With MAC address spoofing, you can configure the router to transmit data using the MAC address that the ISP expects.
Follow the steps below to enable MAC address spoofing:
1.Open a browser window and login to the router.
2.In the menu at the left side of the screen, click Basic Configuration, then WAN, then MAC Address Spoofing. This displays the MAC Spoofing screen (see Figure 14).

3.Click Enable to turn on the MAC spoofing feature.
4.To have the router use the MAC address of the PC you are currently using, click Spoof this PC MAC Address and then click Execute. The router will automatically obtain the MAC address from the computer you are using and enter it into the MAC address field.
5.To manually enter a specific MAC address, click Manually enter MAC Address, then enter the MAC address. Be sure to enter the six separate parts of the MAC address into the six separate boxes in the field.
