Describes the configuration of ADSL Wireless Internet sharing and wireless network card.

This article introduces the configuration of ADSL Wireless Internet sharing and wireless network card. First, let everyone know the basic process of configuring ADSL Wireless Internet sharing, and then compare the advantages and disadvantages of the following methods. The wireless solution of the notebook is usually implemented through the wireless network card of the notebook and the PCMCIA wireless network card of the notebook. For information about how to set the wireless network card of the notebook, see the instruction manual, the following describes how to set a wireless network card for a PCMCIA notebook:

◆ For a notebook PCMCIA, insert an empty-slot computer to find the hardware (in this case, the "LINK" Light of the NIC flashes green), and install the driver on the CD, after the network is restarted, you can view the hardware information NETGEAR MA401 wireless PC Card in the network properties.

◆ We will assign the IP address 192.168.1.5 (mask 255.255.255.0) for its ADSL Wireless Internet sharing, and restart it after confirmation.

◆ After the machine is restarted, a green icon in the lower right corner will be displayed flashing, indicating that the wireless network adapter is working properly, however, this does not mean that it has been connected to a wireless router and other machine networks in the same network segment, and further configuration is required. Reference Paper, define "Profile Name" as "HXJ1", and select the default value of Infrastructure Access Point for Network Mode). The SSID must be consistent with the SSID in the wireless router, otherwise the Network will not be connected. Select "Fully Automatic" for Automatic adaptation for Tx Rate ).

◆ After configuring the above-mentioned ADSL Wireless Internet sharing settings, you must set encryption items. Select "encryption" to make the settings consistent with those of the wireless router. The number of BITs encrypted by WEP is 64 bits, and enter the same number sequence as that of the wireless router after KEY1. After the configuration is complete, click "OK" to complete the configuration.

◆ Test connectivity. If ping 192.168.1.5 and Reply are normal, the network is successfully established.

 

ADSL Wireless Internet sharing settings

◆ Conclusion: we can share the ADSL Network so far, but we cannot rest assured now. First of all, the security of the network cannot be ignored. We also need to add some configuration to enhance the security of the wireless network.

First, we need to set the administrator password for ADSL Wireless Internet sharing, and then consider whether to enable the WEP encryption function. However, I prefer to disable WEP and use the MAC address control mechanism, this not only facilitates the configuration of the client wireless network card, but also avoids the slight impact of the WEP encryption process on the wireless network speed.

From the perspective of ADSL Wireless Internet sharing security, even if your wireless signal can be received by others, the wireless network card they use is not in the list of allowed MAC addresses, they cannot access your wireless network either. Of course, if you prefer WEP encryption or two access restriction mechanisms at the same time, you can also.
