How to configure your wireless network

Wireless local Area network technology has now been very perfect, faster and faster, has been able to achieve the speed of ordinary wired Ethernet, wireless signal security has been basic protection. More importantly, the wireless network can plug and play without wiring, so for consumer-type home users, is the best choice for the networking program. And now that a lot of friends have bought a Centrino laptop, it's a matter of time before you buy a wireless router home.

But here's the problem, routers buy back How to configure the people are concerned about the problem, in fact, configure a wireless network is very simple, do not think that more than a "wireless" two word problems will be complicated, configure wireless routers and configure a limited router, just a few places to pay attention to, only a few minutes can be easily done. Let me show you how to make a key.

To buy back the AP, the first thing to do is to put the position. The speed of wireless network is obviously affected by distance and obstacle, as the central node of the AP is best to center in the physical location, and there is no barrier to the housing space, such as in the living room, if the duplex structure or villa can be considered to add a gain antenna (detailed content can browse the site's "enhanced signal don't worry, Wireless gain antenna Shopping Guide "article" and also to avoid the AP placed in the corner and other places easily trampled, bump.

Find the right place to put it, and then it's time to configure it. Each device that complies with the TCP/IP protocol access network has its own IP address, and the wireless router is no exception. The general AP will have its own fixed LAN IP address, this design is also convenient for us to access this IP address to configure and carry out the testing of wireless routers. Of course, the different brand model of the wireless router IP address is not the same, you can refer to the AP instructions. Also need to be aware that the network card must be connected to the same IP network segment, such as the small series of Siemens 2624 AP IP address is 192.168.254.254, then the network card IP can be designated as 192.168.254.XXX network segment of any address.

Now many AP support Browser Direct login configuration, encountered unsupported can refer to the instructions set. Open a Web browser and enter the address of the wireless router in the address bar, and the system will require a login password. Generally speaking, the password can be queried on the product specification. For a new router that is not set up, some also appear with the Setup Wizard (Setup Wizard). In a page called connection configuration, we can select the type of broadband network, the general ADSL option via PPP over Ethernet, and cable or FTTB select via DHCP. If the ISP needs to enter a username and password, we can enter it at the appropriate location below and set the timeout to around 120s. We can then set the wireless router's Essid defaults to WLAN, and do not forget to click the Save button when the settings are complete.

If the wireless router also needs to connect the 100/10m wired network for use as a wired router, then we need to further setup. The system IP Configuration configuration Interface, under options such as IP/DHCP, will be set to enable when DHCP is configured so that once the TCP/IP properties of the user's wired network card and wireless network card are set to automatically obtain an address, You can get an IP address from the wireless router. As for the DNS IP address, you can query the local ISP, generally do not set also can.

In addition, like BT friends after using the router will find the download speed slows down, the best solution is the port mapping, in the router set the method is for your machine intranet IP address open DMZ function. Note that the BT port number should be consistent with the settings on the router.

Configuration of wireless clients

The most important of the client's configuration is the Essid value, which must be guaranteed to be exactly the same as the ESSID value of the AP (including letter case). Essid value is like a wireless client and wireless router between a password, only in the same premise to allow wireless network card access to the wireless router, which is also to ensure the safety of wireless networks one of the important measures. Different wireless card settings Essid place is not the same, some in the control Panel, some through the network card-specific applications, can refer to the manual. Generally the same brand of wireless router and wireless network card using the same Essid default value, no need to set up to use, but for business users, this will bring some security risks, the proposed replacement Essid value.

The other configuration of the wireless client is very simple, and the past annoying network settings can all be thrown away. Open the TCP/IP properties of the wireless network card in the network properties of the Control Panel, and then set the IP address to automatic and DNS set to Automatic, when the wireless network card can be automatically assigned to the IP address and connected to the Internet.

If you set up WEP wireless encryption on the AP, then you also need to fill in the key on the Wireless Options menu, which is more convenient for XP operating system, and many of the wireless drivers with the Centrino notebook have this function.

Usage considerations

1, generally speaking, because all in the unified 802.11b standard, all wireless network card and wireless AP will not have compatibility issues, but for the sake of stability, for higher requirements of the occasion is recommended to use a unified brand of AP and wireless adapter.

2, the load-bearing wall of reinforced concrete structure is very strong to the wireless signal. If the duplex structure of residential or villas to consider the layout of wireless network, each layer is configured AP seems to be absolutely necessary. In practical applications, the coverage of indoor AP can only be up to 30 meters.

3, 802.11b actual use rate of only about 40% of nominal value, the conversion of data per second is about 600KB, if again set to 64-bit WEP encryption transmission rate will be further reduced. Therefore, the use of more attention to anti-interference, away from the microwave, Bluetooth equipment and other interference sources.
