Papers to write Net: Abstract: home wireless LAN is the network of information technology needs of the user another manifestation mainly for the preparation wireless LAN networking, wireless router settings and at this stage of the home wireless LAN and other defects and deficiencies areas to elaborate, to help people learn more about wireless LAN set up relevant content.

Paper Keywords: home wireless LAN, wireless router, information technology

With computer technology and electronic information technology matures, the electronic products with unprecedented speed quickly into millions of households, while the popularity of the network, the Internet home users demand more and more. If we are able to complex organic electronics to connect, to form a home network, you can share hardware and software resources, rational use of network resources to meet the needs of family members to use. How to choose a simple and effective way to build a home network is the subject of this paper.


First, the network preparation

Wireless LAN in a family before, according to their own family needs analysis, this paper basically a desktop computer, a laptop, a cell phone (to support the WLAN described.

Select the networking
Home wireless LAN network the easiest, most convenient way is to choose the peer that the wireless router as the center, the other computer via wireless LAN and wireless router.

Equipment purchase
A choice of modem and router accordance with broadband access, when users access broadband via the telephone line, you must also purchase a modem and wireless router and when users access using optical fiber, then just buy a wireless router, you can for sharing Internet access in selected modem, ADSL broadband speeds with just a match to complete the digital-analog conversion of broadband Internet access, while for the wireless router, not only to consider the transfer rate, but also consider the coverage of signal strength to ensure that family within no corners.

2 cards of choice for desktops, the need to access the wireless network with a wireless card. Internal PCI wireless network card into an external USB wireless card and wireless card. PCI wireless network card has the advantage of directly between the computer memory exchange of data, reducing the burden on CPU, but the signal receiving position is not adjustable, the host computer vulnerable to interference, easy dropped. The wireless card has a USB interface, plug and play, cooling performance, transmission speed advantages, combined with cheap, as extended desktop of choice.

The location of the wireless access point
Wireless access point that wireless router, the signal will be wired into a wireless network signal [2] in the home wireless LAN, you should first consider the placement of the wireless router, wireless signals can pass through walls, but its signal will be hampered as material number, thickness and location of the rapid decay, to make the wireless signal can cover the entire family area, must try to make the signal directly through the opening in the wall or the formation of the direct signal transmission in the actual equipment layout arrangement, but also according to family housing structure, whether the interference of other signal sources, fine-tune the location of the wireless router.


Second, the wireless router settings

In this paper, mobile PPPOE fiber access, use TP-LINK TL-WR740N introduced as a benchmark to set the wireless router.

Basic Connection
First, the optical interface is connected to the power supply into the wireless router's WAN port, the hardware connection, and secondly, search for wireless signals, click the "Menu" in the "Control Panel", double click to open "Network Connections" in the network Connection window, double-click to open "Wireless Network Connection" in the "General" tab, click the bottom right corner of the "View Available Network Connections", click "Refresh network list" and finally click "Connect", the realization of a computer and a wireless router in this process, ensure the wireless network TCP / IP to automatically obtain the IP address selection, again, landing router's Web management interface, enter the default in the browser's address "192.168.1.1".

Be the set
1 Click Setup Wizard to guide the setting setup wizard can help us to easily set up the router, the Setup Wizard dialog box appears, click "Next."
2 Select the network connection. In the Setup Wizard - Internet mode window, the three most common means of access are available for PPPoE (ADSL virtual dial-up), dynamic IP and static IP. Because PPPoE is the most common means of access, such as telecommunications, CRC, Netcom all use this method, so select this method, and click "Next."

4 wireless basic parameter settings, set the network to ensure network security password can use the wireless settings window, were set two, namely, the basic parameters of the wireless network and wireless security options set. "Basic parameters" including wireless status, SSID , channel, mode and frequency bandwidth, "wireless security options," including not open wireless security, WPA-PSK/WPA2-PSK and does not modify the wireless security settings here only requires the user to set options in the PSK wireless security password to protect network security, other options are the default settings Click Next to complete the setup, wireless LAN set up.

Other features settings
In the wireless router's Web management interface, in addition to the setup wizard function, there are many settings, such as a DHCP server option, and security settings. DHCP service is a network settings such as the foundation for any wireless device to connect the wireless router assigned IP address the router software to provide "not enabled" and "Enable" two states, the default is set to "Enable" in the user, the router automatically assigns IP addresses for network dial-up connection, without any user connection settings, This is also another major advantage the wireless router. provides a network firewall security settings, user-specific settings can filter the domain name, with the anti-attack capability, to ensure its own security. users set up a wireless router, can be according to their needs for the set.


Third, the home wireless LAN defects and deficiencies

Network formation requires a certain knowledge of the family to build and maintain wireless local area network
A successful wireless Local Area Network, will be able to meet the needs of users, the most economical equipment to achieve maximum hardware utilization efficiency, which requires the user to set up wireless LANs have some understanding and to avoid blindly buy networking equipment, its use of unnecessary procedures or economic problems. Secondly, the maintenance is for wireless LAN users need to master a technology index. If you know some basic knowledge of network construction for everyday use in the emergence of some small problems or obstacles, they can in a short period of time remove obstacles, and will not affect the user.

The formation of the high cost of home wireless LAN
Wireless LAN in the home building, to build the core of the wireless LAN device is a wireless router. In general, the market price of the wireless router wired router is relatively high, and set up a wireless LAN, if the desktop, you also need to purchase a wireless card, which undoubtedly increased the amount spent.

Relatively poor stability of the wireless LAN signal
Wired network through a hardware transmission medium for signal transmission, the signal is stable and not affected by external factors, while the wireless LAN is to rely on radio waves for transmission, the radio transmitter through the wireless transmitting devices, or building block in the distance case, the signal quality will be relatively poor. Second, the relatively slow speed of wireless networks, wired networks can not be achieved to reach the speed of these factors, will affect the users on the network use.

Security is poor
At this stage, the development of wireless LAN technology is not very mature, network security has become the signal of risk. Radio waves are not required to establish the physical connection from the wireless signal divergence, as long as the signal coverage of wireless access points within any device can easily be listening to the radio broadcast range of any signal, resulting in communication and information leakage, which has become the most fatal weakness of the wireless LAN.


IV Conclusion

Wireless LAN technology with its own unique advantages will be more and more home users are using, although this was not the development of network technology is very mature, there are many issues to be people to solve, but the wireless network technology in the future will become technology to the mainstream, to people's lives more convenient.
