Notes for using a Broadband Router

At present, most broadband routers are stupid products. Users only need to understand some computer knowledge and simply take a look at the instructions to achieve Internet sharing through network connections. However, for some new users, you should pay attention to the following issues.

1. connection to a computer or vswitch

The lanports of a Broadband Router can be connected either directly to a computer or to a collection line device (HUB or switch ). If the number of computers is small, you can connect them all to the lanport. If the number of computers is large, you can connect the lanport with the set line device to provide Internet Connection Sharing for more computers.

Note that different twisted pair wires must be used to connect the cabling devices and computers. Otherwise, the connectivity may fail. In general, the connection computer uses a straight line, and the connection set line device should use a cross Line (except for connecting to the Uplink port ). In addition, there are also some products that support smart ports (such as D-Link, TP-LINK, etc.), these products can all use direct line.

2. Connection to ADSL Modem

When a Broadband Router is used for Internet connection and sharing, the ADSL Modem must use an Ethernet interface and connect to the WAN port. The ADSL Modem of the USB interface cannot connect to the Broadband Router. In addition, the connection between the ADSL Modem and the Broadband Router should use a direct line.

Iii. DHCP and IP address pool

By default, the DHCP service is enabled for the Broadband Router. That is to say, the computer in the network only needs to select the "automatically obtain IP address information" option to assign IP addresses through DHCP. However, pay attention to the following points during actual operations:

1. When using the residential broadband access method, make sure that the internal IP address allocated by DHCP is different from the IP address used by the residential area.

2. When a Broadband Router uses a static IP address, in addition to the assigned IP address and subnet mask, you must specify the IP address of the DNS and the default gateway, and set the DNS forwarding function of the Broadband Router.

3. When using ADSL to access the Internet, you often need to set VPI and VCI values. These values can be queried from the broadband provider.

Iv. Automatic disconnection

If the hourly fee standard is adopted, the router should be set to "on-demand connection". An Internet connection is established only when the user sends an Internet request. At the same time, you should also set the waiting time for automatic disconnection, that is, when there is no Internet access request within the specified time, the router can automatically cut off the ADSL connection, thus saving access costs.

5. MAC Address binding

Some broadband providers have bound MAC addresses on the authentication server to limit the number of connected users. At this point, you can first connect the computer bound with the MAC address to the lanport, and then use the MAC address cloning function to copy the MAC address of the NIC to the WAN port of the Broadband Router, to achieve Internet Connection Sharing of the entire network. It should be noted that the MAC address cloning function is supported by products such as middleware, TP-LINK, and D-Link.
