How can I use an ADSL account to enable two computers to access the Internet at the same time?

1. you can directly use the ICS shared by the operating system-one machine as the host, which is used to dial up and install dual NICs (so you do not need to purchase additional hubs or switches, you only need to add one more NIC-two computers have three NICs, and make sure that machine 2 needs to access the Internet, machine 1 is the master server ).
ICS (Internet Connection Sharing) is a shared Internet service built into Microsoft Windows 2000/XP. When using this service, you only need to check it to start the service. Another machine to share this broadband connection, need a cross Line (couplet line), that is, one is made into the EIA-T568a standard interface, the other is made into the EIA-T568b standard interface, the length must exceed 1 meters. This cross-line can also be done by yourself. If you do not, there will usually be sellers selling such lines in the Computer City.
Set IP Address: in addition to the IP address, you must set DNS and the gateway address must be 192.168.0.1.

2. If the ADSL modem has the routing function, you can use the modem itself as a host (you need to buy another hub or switch ).
1) Modem adopts the built-in pppoe dial-up mode; LAN uses private network addresses, and address allocation can adopt static configuration or dynamic DHCP allocation.
2) If dynamic allocation is adopted, the modem must have the DHCP function and enable this function.
The implementation method is actually quite simple, as long as the configuration is correct according to the instructions. Next, let's talk about the specific configuration: connect the NIC of the host to the ADSL Modem. Suppose that the default IP address of the modem is 192.168.1.1, therefore, we must first set the computer and ADSL modom to the same network segment; otherwise, communication will fail. The procedure is as follows (taking Windows 98 as an example, the settings for other systems are similar ). Right-click the "Network Neighbor" icon on the desktop, select "properties", double-click the TCP/IP protocol corresponding to the NIC in the displayed dialog box, and fill in the following content in the displayed dialog box: the IP address is 192.168.1.2 (do not fill in 192.168.1.1 because it is occupied by modem). The subnet mask is 255.255.255.0 and the gateway is 192.168.1.1. After completing the above work, we will start to configure ADSL modom. Open IE, enter 192.168.1.1 in the address bar, and press enter to display the user login page. In the "user name" and "password" columns, you can log on to the vro management interface after the user name and password of the modem are respectively entered.
Open the web page and click "ATM setting" to change the operate mode to enable. In the drop-down list of the Connection Type field, select the "pppoe LLC" option from the text box. The principle of pppoe MUX or pppoe LLC is consistent with the NAS encapsulation method, generally, it is recommended to use the LLC encapsulation method. Assume that the default PVC encapsulation is the LLC method. Modify the default router to enable. Based on the information provided by the ISP or system supplier, fill in appropriate numeric values in the corresponding fields, such as "VPI", "VCI", "pppoe User Name" and, "pppoe password"
(Note: What should I do if the "pppoe User Name" and "pppoe password" will be provided by the Telecommunications Bureau staff when installing ADSL, but the "VPI" and "VCI" are not provided? In fact, you only need to make a phone call to the Telecommunications Board to ask, the "VPI" and "VCI" values in different regions are different) and click <"Submit>" at the bottom of the field to submit. Note: The Nat function must be enabled (this is a key step ). Click the "Save & reboot" Directory on the Web page, and click the <save> button to complete the ADSL terminal setting and save it permanently. In the "reboot mode" dialog box, select "reboot ", make the settings take effect.
Reminder: If you set the static IP address, gateway address, and DNS server address on your PC, we recommend that you enable the built-in DHCP function of modem to automatically configure the PC. Select DHCP from the lan dsl and other config menu and select the DHCP server option. Then, you can set the automatically obtained IP address on the PC side.
If your ADSL modem is not in the same place as the hub, you need to build a network cable to connect the adslrouter to the hub, note that the production of the network cable is the same as that of the "dual-host couplet". It is "1---3, 2----6" and connected to the ADSL modem after the cable is prepared. If the CD light on the ADSL modem is, if the LAN is on, it means it is normal. Wait a few minutes until the ADSL modem Initialization is complete and you can access the Internet.
