How to Implement WLAN multi-host shared wireless Internet access

Multi-host shared wireless Internet access is the main content of this article. For more information about how to use single-host wireless Internet access, see steps for achieving single-host WLAN wireless Internet access.) for details about how to use dual-host wireless Internet access, see steps for achieving WLAN dual-host wireless Internet access. now, it is easier to configure multi-host shared wireless Internet access.

To achieve multi-host shared wireless Internet access, we need to select wireless network devices, including wireless NICs, Wireless AP or wireless routers. Because the wireless router also has various features on the basis of the Wireless AP function, it is better to select a wireless router.

(1) hardware connection

Take the TP-LINK Wireless Broadband Router as an example, the hardware connection reference above to set up the home/Office Wireless LAN method, the WAN port of the wireless router and the Internet portal connected with a network cable. A general wireless router also has a built-in switch that provides four ports to connect to other network devices or computers. However, in addition to integrating the WAN port, some wireless routers also provide all ports of the common switch, including Uplink and other common ports. If the Uplink port has been cascade with the HUB or vswitch, the common port next to the port will not be available.

(2) set up a wireless router

If you build a common wireless LAN, use the default settings of the wireless router (that is, do not need to set), but to achieve multi-machine sharing wireless Internet access, we need to pay attention to the following settings:

First, we need to set the Internet connection type:

Also open the settings page for the TP-LINK wireless router, in the basic settings page, you need to select the WAN port connection type according to the Internet access situation.

For example, for the ADSL user mentioned above, select PPPoE and enter the user name and password. For residential broadband access, you can choose to automatically obtain the IP address. for optical fiber access, select static IP, the IP address, subnet mask, default gateway address, and DNS server address are also specified. for users who need secure network transmission, PPTP connection can be used, enter the IP address, subnet mask, gateway, user name, and password. After the selection is complete, click the "application" button.

To achieve multi-host wireless Internet access, we also need to set the SSID:

If you do not want to use the default SSID value of the wireless router, you can modify it on the wireless router Management page. Open the management page, click the "Basic settings" link in the left-side window, enter other values in the "SSID" box on the right side of the page, and ensure that the SSID broadcast is set to "allowed ". Click "application.

Finally, configure the steps for multi-host shared wireless Internet access and set the wireless network adapter:

In Windows XP, we have already introduced how to set a wireless network card. Note that the IP addresses are set to "automatically obtain IP addresses" or the IP addresses in the same CIDR block as the wireless routers. To manually create a wireless network connection, make sure that the SSID of the wireless network adapter is the same as that of the wireless router. In addition, the Advanced Access Mode of the wireless network adapter must be set to "any available network (preferred access point)" or "only access point (structure) network ".

However, for Windows 98/2000 systems, wireless network card configuration cannot be performed automatically, which is also mentioned when setting up a home wireless LAN. Then, we can configure the wireless network through the client software that comes with the wireless Nic drive disc to achieve shared Internet access.

ToWindows 2000 Professional as an example, TP-LINK TL-WN250 2.2 wireless network card configuration method is as follows:

First, the wireless network card installation disc into the optical drive, run the disc TP-LINK 2.2 wireless network card automatic installation software package, one click "Next" button to complete the installation of the driver and configuration software.

Security Settings for multi-host shared wireless Internet access also require a lot of attention. Right-click the taskbar connection icon and select "Config/Link Status" to open the configuration dialog box. Click the "Available Network" tab and click "Refresh" to search for Available wireless networks. The search results are displayed in the list, includes the SSID, channel, encryption, and network authentication of the wireless network. Click "Add to Profile" (Add to configuration) "button to add the wireless network configuration to the current wireless network card settings, click" OK.

If the selected wireless network requires a key, you also need to select the "Data encryption (WEP enabled)" option in the "Network Properties" dialog box, enable WEP Data Encryption. Select "Network Authentication (Shared mode)" to enable Shared Network Authentication) enter the network key in the "Confirm network Key (Confirm network key)" box, Confirm the network Key, and enter the key index in the "Key index (advanced)" box. Click "OK.

After adding the searched wireless network configuration information to the current wireless network card configuration, click the "Profile" tab to view the added configuration file, click the Edit button to change the setting value of the selected configuration file. Click Add to Add a new configuration file, click "Set Default" to Set the selected configuration file as the Default configuration file. Click the General tab to view the working status of the wireless network adapter, including the speed, network type, encryption, SSID, network address, and other information.
