How to easily set up a wireless router (1)

With the price reduction of wireless network devices, it is no longer an inevitable dream to build a local WLAN at home. These SOHO-level wireless devices are generally easy to set up. For users who do not know much about wireless networks, you can use the default configuration. However, the default configuration of WLAN is flawed in management and security, especially security. In addition, when users fail due to incorrect parameter settings, they are often helpless because they do not know the specific meaning of the parameters. Therefore, it is necessary to understand the parameters in the wireless network configuration. In addition, because the wireless router not only has all the functions of AP, but also integrates the routing and management functions of the Broadband Router, you only need one wireless router to build a WLAN for the home. The difference between pure AP devices and wireless routers is getting smaller and smaller, so more users will choose wireless routers. This article is mainly to TP-LINK WR245 wireless router as an example, the home wireless network settings are explained. Rest assured that the setting interface is slightly different. The wireless setting parameters of most wireless routers and APs are similar .)

I. Initial settings of Wireless Parameters

Figure 1

From the settings bar on the management interface, we can see that this Wireless Broadband Router has the same configuration items as those of the same level of Wired routing products except for one more wireless setting, the setting methods are the same, so this article only describes the wireless settings. Like the TP-LINK R4x0 series Wired Broadband Router, the initial Internet access settings can be performed using the setup wizard, with the setting parameters in addition to the final "Wireless Settings" figure 2) and R410.

The "wireless function" determines whether the AP function is enabled. The "SSID" is also abbreviated as ESSID, which is the identifier character of the AP and is sometimes translated into "Service Set Identifier or service area identifier ", is used as a verification identifier for accessing this wireless network, which can be imagined as a working group name in a windows File Sharing Environment ). To add a wireless client to the wireless network, it must have the same SSID number; otherwise, it will be "REJECTED ". This is the TP-LINK by default, it is recommended to change to an uncommon name, can be used as a simple security measures, of course, the need to prohibit the use of SSID broadcast, which will be discussed below.

"Frequency Band" is also called "Channel", which uses wireless signals as the data signal transmission Channel for transmission media. IEEE 802.11b/g works on 2.4 ~ 2.4835GHz Chinese standard). These frequencies are divided into 11 or 13 channels. The WR245 wireless router can select 11 frequency bands. When there are more than two aps in the environment or overlap with the AP coverage of the neighbor, you need to set different frequency bands for each AP, to avoid conflicts. After this step is complete, the most basic network parameters are set. If you do not have any security requirements, the client wireless Nic can be connected by default.

Ii. Advanced Settings of Wireless Parameters

Generally, wireless routers and APs have the following three settings:

Chinese name	English name	Features
Basic Wireless Settings	Wireless Settings	Wireless network parameters, including SSID, channel, security authentication, and key. 3)
MAC address filtering	MAC Filters	An access security mechanism can restrict unauthorized hosts to be added to the wireless network only for the wireless network). It is based on the MAC address of the NIC. 5)
Host status	Client State	Displays the basic information of all hosts connected to the wireless network, including the MAC address. 4)

In addition to the Enable, SSID, and frequency bands of the wireless functions set in the Wizard, this page also provides more security settings. If "allow SSID broadcast" is selected, the vrossid will broadcast its own SSID number to all wireless hosts, that is to say, the wireless network adapter without the specified SSID can get the SSID broadcast by the AP and connect it. If you do not want to have other wireless clients nearby, you are advised to cancel this option and manually specify the same SSID in the wireless settings of the client Nic to connect.

In "Security Authentication Type", you can select the "Open System" mode that allows any access, the "Shared Key" mode based on the WEP encryption mechanism, and the "Automatic Selection" mode. For security, we recommend that you select the "Shared Key" mode.

In "Key format selection", you can select the ASCII code or hexadecimal number used in the following key. Generally, we select HEX in hexadecimal format ). In the following key information, enter the content items as instructed.-"to select a 64-bit key, enter 10 hexadecimal numbers or five ASCII characters. To select a 128-bit key, you must enter 26 hexadecimal numbers or 13 ASCII characters ". Then select the number of encrypted digits in the key type. You can select 64-bit or 128-bit. If you select disable, the key is not used. Note that you can only select one valid key at a time, but you can save up to four keys. In addition, the higher the number of encrypted digits, the lower the communication efficiency, that is to say, the connection speed will be affected. Therefore, we recommend that you do not have to select a too high number of encrypted digits in an environment that is not sensitive to security at Home WLAN.

2. Host status

You can view the host information that is added to the wireless network on this page. The most important thing is to obtain the MAC address for use in MAC address filtering.
