Description
• Get Dynamically from ISP. Your ISP uses DHCP to assign your
IP address. Your ISP automatically assigns these addresses.
• Use Static IP Address. Enter the IP address that your ISP
assigned. Also enter the IP subnet mask and the gateway IP
address. The gateway is the ISP's wireless-N modem router to
which your wireless-N modem router will connect.
• Use IP Over ATM (PoA). This option is only available if your ISP
does not require a log in.
The DNS server is used to look up site addresses based on their
names.
• Get Automatically from ISP. Your ISP uses DHCP to assign
your DNS servers. Your ISP automatically assigns this address.
• Use These DNS Servers. If you know that your ISP does not
automatically transmit DNS addresses to the wireless-N modem
router during login, select this option, and enter the IP address of
your ISP's primary DNS server. If a secondary DNS server
address is available, enter it also.
NAT automatically assigns private IP addresses (10.1.1.x) to LAN-
connected devices.
• Enable. Usually NAT is enabled.
• Disable. This disables NAT, but leaves the firewall active.
Disable NAT only if you are sure that you do not require it. When
NAT is disabled, only standard routing is performed by this
router. Classical routing lets you directly manage the IP
addresses that the wireless-N modem router uses. Classical
routing should be selected only by experienced users
Your computer's local address is its unique address on your
network. This is also referred to as the computer's MAC (Media
Access Control) address.
• Use Default MAC Address. This is the usual setting.
• Use Computer MAC address. If your ISP requires MAC
authentication, you can use this setting to disguise the wireless-
N modem router's MAC address with the computer's own MAC
address.
• Use This MAC Address. If your ISP requires MAC
authentication, you can manually type the MAC address for a
different computer. The format for the MAC address is
XX:XX:XX:XX:XX:XX.
