Always on: A connection to the Internet is always maintained.
On demand: A connection to the Internet is made as needed.
Manual: You have to open up the Web-based management interface and click the Connect button
manually any time that you wish to connect to the Internet.
Maximum Idle Time: Time interval the machine can be idle before the PPPoE connection is
disconnected. The Maximum Idle Time value is only used for the "On demand" and "Manual" reconnect
modes.
WAN Interface IP Type
Static: If your ISP has assigned a fixed IP address, select this option. The ISP provides the values for
the following fields for WAN Interface IP Setting:
IP Address, Subnet Mask , Default Gateway, and optional for
DNS Server
Dynamic: If the ISP's servers assign the router's IP addressing upon establishing a connection, select
this option.
WAN MTU Setting
The Maximum Transmission Unit (MTU) is a parameter that determines the largest packet size (in
bytes) that the router will send to the WAN. If LAN devices send larger packets, the router will
break them into smaller packets. Ideally, you should set this to match the MTU of the connection
to your ISP. Typical values are 1500 bytes for an Ethernet connection and 1492 bytes for a PPPoE
connection. If the router's MTU is set too high, packets will be fragmented downstream. If the
router's MTU is set too low, the router will fragment packets unnecessarily and in extreme cases
may be unable to establish some connections. In either case, network performance can suffer. t
modes.
MAC Address Clone
Each networking device has it's own unique MAC address defined by the hardware manufacturer.
Some ISP's may check your computer's MAC address. Some ISP's record the MAC address of the
network adapter in the computer or router used to initially connect to their service. The ISP will
then only grant Internet access to requests from a computer or router with this particular MAC
address. This router has a different MAC address than the computer or router that initially
connected to the ISP. If you need to change the MAC address of the rounter's WAN-side Ethernet
interface, either type in an alternate MAC address (for example, the MAC address of the router
initially connected to the ISP) or copy the MAC address of a PC. To copy the MAC address of the
computer that initially connected to the ISP, connect to the router using that computer and click
the Clone Your PC's MAC Address button. The WAN interface will then use the MAC address
of the network adapter in your computer.
