How to Set up a wireless router in a LAN

I believe that users who use wireless routes should be familiar with wireless router settings and understand the specific steps and rules. Many laptops have infrared interfaces, the infrared interface is suitable for connecting a notebook and a notebook without a NIC/network cable.

Generally, the infrared devices and ports in the notebook are opened by default. If your notebook supports a speed of 4 Mbps, you can press F2 or another key to enter the BIOS of the notebook, in the BIOS "UART Mode Select Infrared Transmission Mode", Select "ASKIR" to make your infrared reach a speed of 4 Mbps during transmission .), When you install an operating system for your laptop, you usually install the driver and the fast infrared protocol. In this case, you only need to open the "infrared" icon in the "control panel" and select all the options in the "options. In actual connection, the infrared interfaces of the two laptops are aligned. When the system prompts that the two laptops have been connected, a sound prompt is displayed. In addition, in the taskbar in the lower-right corner of Windows, you can also see the icon that the connection has been established.) At this time, the system automatically runs the wireless connection program, you can select the file you want to swap for file transfer. It should be noted that, although the infrared line is convenient, it also has disadvantages such as low connection quality, near distance, and slow transmission speed. It is suitable for the exchange of some small files.

Connect the USB connector.

USB interfaces are currently the mainstream interfaces of computers, and almost all laptops have these interfaces. Therefore, using them for online connection is certainly very convenient. To connect two computers through a USB interface, first you need to buy a "USB connector" or a USB pair cable or a USB virtual network card cable in the computer store, there is a bulging package in the middle of the cable, which is obviously characteristic). The price is generally about 50-yuan based on the brand and quality.

Connect the cables to the USB ports of the two computers. Then, the system will prompt you to find the new hardware, but it cannot be properly recognized. Plug in the installation disc of the USB connector to the corresponding installation directory and file, the mouse is named pc-pc-linq.exe execute file, open and click "Next", after completion, a icon named "PC-LINQ" will be generated on the desktop, and then restart the computer. When you enter WINDOWS again, the system will automatically find the "USB connector" virtual NIC Driver and install it on your own.

The other computer also installs the software and driver in the same way. After everything is okay, You can execute the "PC-LINQ" file on both computers, and in the window that opens, you can drag or COPY any file on another computer. The advantage of USB connector is that the speed is much faster than that of serial port connection, and the stability is better than that of infrared connection. However, its weakness is that it cannot be used for Internet sharing. Network Adapter should be the best way to connect laptops, because it can not only achieve resource sharing through network connection, but also share the internet.

1. How to Create accessories and network cables

Most laptops have built-in NICs, but it doesn't matter if your laptop does not have a built-in Nic. You can choose a PCMCIA Nic. Tip: the PCMCIA Nic is a type of NIC used for laptops. The PCMCIA bus is divided into two categories: one is a 16-bit PCMCIA and the other is a 32-bit cartana. Cartana is a high-performance PC Card Bus Interface Standard for laptops. It not only provides a faster transmission rate, but also can exchange data directly with the computer memory independently of the master CPU, this reduces the CPU burden, so you can choose the preferred one. Then, it is recommended) You can create a "network card connected to the network card for dual-host couplet)" and a "network card connected to the Hub", the length is generally 3-5 meters. During production, it should be preferred a soft and easy-to-fold high quality twisted pair wire.

2. configure a wireless router for Internet sharing

After the accessories are ready, first install the NIC driver, and then install the relevant network protocol according to the method described in "1. Local Area Network Basic wireless router settings, you can easily share resources between your laptop and other computers by inserting a network cable in the RJ45 network interface of your laptop. However, one of the biggest advantages of NIC networking compared with the previous several online methods is that it can share the Internet. Next we will focus on how to configure a wireless router for Internet sharing (PWIN98 ).

This machine is used to configure a wireless router for shared Internet access.

Step 1: Install the corresponding MODEM, ISDN, And ADSL drivers and nic drivers, and ensure that the MODEM and Internet connections are normal.

Step 2: Right-click "Network neighbors" and select "properties". In the "network" dialog box that appears, find the network interface card of the local TCP/IP protocol) for example, "TCP/IP> Intel 21143 based 10/100 mbps ......", Double-click its "attribute ". Select the "DNS configuration" item, tick it before "Enable DNS", and select a name from the host item, in the "DNS server search order" column, set its wireless router to the IP address of the ISP Server that provides Internet services for you, for example, "61.139.2.69" Sichuan Telecom ISP ), "Add" and then "OK. Select "specify IP Address" in "ip address", set the local IP address to 192.168.0.1, And the subnet mask to 255.255.255.0. "OK", restart your computer.

Step 3: Next, If you want other computers to share the Internet with you, you need to install a shared Internet software. Generally, we recommend that you use the "Internet Connection Sharing" built in the operating system after PWIN98 of Microsoft to achieve Internet sharing. It supports MODEM, ISDN, ADSL, and other Internet access methods ). Choose "Control Panel"> "Add/delete programs"> "Windows Installer"> "Internet tools", double-click it, and select "Internet Connection Sharing ", then, "OK", the system will install and configure the program for you.

Step 4. After "Internet Connection Sharing" is installed, the system will go to the "Internet Connection Sharing wizard" and select "Next ", select the "dial-up adapter" when selecting the "use when connecting to the Internet" Network Adapter. For ADSL, select "Efficient networks p. p. p. o. e. adapter). After "Next", select the NIC name of the Local Machine for "use when connecting to my home network", such as "Intel 21143 based 10/100 mbps ......", When you configure a disk, you can select "cancel". After "Next", the Internet Connection Sharing configuration is completed. Then press the prompt to restart the computer to share the notebook with multiple computers online.

The Local Machine implements shared wireless router settings for the slave machine

Step 1: Right-click "Network Neighbor", select "properties", and find the TCP/IP network adapter in the "network" dialog box that appears. Double-click "properties ". Select the "DNS configuration" item, tick it before "Enable DNS", and select a name from the host item, in the "DNS server search order" column, set the wireless router as the address of the local ISP Server, for example, "61.139.2.69" Sichuan ISP), "add", and "OK.

Step 2: Select "specify IP Address" in "ip address" and set the IP address of the Local Machine to an address ranging from 1 to, for example, 192.168.0.2 or 192.168.0.119, in short, the ending number must be different from that of other computers on the LAN. The subnet mask is 255.255.255.0.

Step 3: Select "Gateway" and enter the IP address of the host in the "new Gateway" column, that is, 192.168.0.1, and then select "add". After you confirm, restart the computer and the shared host will access the internet. Through our detailed introduction above, do you have a comprehensive understanding of "online notebook technology? Finally, we wish you the best use of your notebook.
