How to install and set up a wireless router

To connect a wireless LAN to the Internet, the most important thing is to have a terminal connected to the Internet, which is a wireless router or Wireless AP. The biggest difference between the two is that a wireless router not only has a WAN port, but generally has four LAN ports. In addition to the wireless function, it is a wired four-port router, wireless AP has only one WAN port, but only a pure wireless coverage. After learning about wireless access devices, we will teach you how to install them step by step.

Wireless Router and AP Installation

Next, the interconnection between hardware. If you select a Wireless AP and a desktop computer, you should also prepare a wired switch. Of course, if you choose a wireless router, you do not need a switch. The connection between the Wireless AP and the wireless router is similar. Next we will introduce the wireless router. We need to select a suitable location within the scope of work so that each terminal is enclosed in the wireless range of the wireless router) Place the wireless router and connect it to the power source, pull out its back-end antenna, connect the network cable to the ADSL Modem.

A wireless router has a network cable that can be connected to its upper-level devices, such as switches or routers, and Internet connection points, such as ADSL cats ), to connect the covered wireless network with other networks. If the access point is an ADSL cat Broadband Router, you can follow 568A at one end of the crystal head, And the 568B standard at the other end, that is, the crossover line) A network cable is directly connected to the wireless network access point and the ADSL modem Broadband Router. Of course, if the wireless network access point is connected to a HUB or switch, then both ends follow the 568A or 568B standard, that is, parallel lines.

Note: The current wireless router or the WAN port of the Wireless AP can be automatically flipped. That is to say, the two lines can be crossed or parallel lines, and they can be adjusted by themselves. For more information about how to create a network cable, see BKJIA networking channel article "illustration: rj45 crystal head network cable practices".

Generally, after connecting to the upper-level device, you can directly use the wireless function according to the default configuration of the wireless router. However, this is guaranteed in terms of management and security. In addition, many wireless routers have setup wizard, which can be easily completed. First, remove the network cable connected to the MODEM to connect the router, and press its default IP address to enter the WEB Settings interface.

You can use a crossover line to connect to your computer and one end to the LAN port of the wireless router. Note that it is not the WAN port). Then, open the IE browser, enter the default IP address of the wireless router in the address bar. Please refer to your product manual, generally http: // 192.168.1.1). Then you will be prompted to enter the wireless router account and password to enter the configuration program, for more information, see the instructions.

Step 1: Pay attention to the IP address of the wireless router. In the end, we need to connect the wireless router to the Modem, so the IP addresses of the two should not be the same. Please modify the IP addresses according to the actual situation and ensure that the subnet mask is the same.

Step 2: Like Modem, we also need to enable the DHCP service function of the wireless router. Find the option to enable.

Step 3: Determine the WAN connection type. Because we have enabled the DHCP function, we should select "automatically obtain IP addresses ".

Step 4: Write down the vrossid ssid number, which is the verification ID for the network adapter to connect to the wireless network normally.

Some problems need to be clarified here. First, after dynamic IP addresses are enabled, you must set the starting IP address. This is based on the IP address of your wireless router, starting from the last digit of the IP address of the wireless router to 255.

The other is that some wireless routers allow you to set the number of users, which depends on your settings in the starting IP address. For example, the starting IP address is 150, the maximum number of users you can set is 105255-150.

Now, you only need to perform these steps to complete the vro settings. Restart the vro to make the settings take effect.

Solution to abnormal wireless routers and AP Networks

A wireless router and Wireless AP can theoretically connect to 254 computers, because different SSID can also be set to WEP password), so you do not have to worry about other unknown users accessing your network. The key point is that if the network connection is abnormal after installation, you can:

① Test the signal strength. If you can Ping an access point from a wired client but not from a wireless client, the access point may be faulty. You can use the measure signal strength function provided by the Wireless AP program to check the signal strength. If it is too weak, the Wireless AP may have quality problems. If the signal status is caused by poor signal status, you can use Windows XP's "wireless network connection" or "Wireless Access Point" attached software for detection ).

When using Windows XP, you only need to click the network connection icon in the taskbar to display the connection status window. If four or five green lines are displayed, if only one or two lines are displayed, the signal status can be determined to be poor, and the placement position and antenna angle of the AP and wireless network card can be adjusted, to achieve the optimal signal strength.

② Try to change the channel. If you suddenly find that your Wireless AP signal is weak, but you have not made any physical changes. You can try to change the Access Point and the channel of a wireless user or add an external antenna to see if the signal can be enhanced. Because some new wireless phones or microwave ovens) also run at a GHz frequency using 802.11b wireless networks at the same frequency), this may interfere with your wireless network.

③ Check the SSID configuration. When you join other wireless networks, do not forget to change the SSIDService Set Identifier configuration. If the SSID configuration is incorrect, you cannot Ping the Access Point or connect to the network.

④ Check the WEP Key. Many wireless network configuration problems are related to the WEP Protocol. To solve the WEP problem, we need to be very careful. In addition, If WEP is required to take effect, the Access Point and client configuration must be correct. Some clients seem to have no problem in configuration, but they cannot use WEP to communicate with the access point. In this case, you can restart the access point, restore the default value, and then re-configure WEP, then WEP can be used.

⑤ Right-click the Wireless Network icon in the taskbar. Select the "view available wireless networks" command in the next menu, and you will see the wireless network connection dialog box. The dialog window shows any SSID on your current channel that you are not connected. If your wireless network name appears in this list, you are not connected to the network. If your connection is good, your configuration may be faulty. In addition, you need to enter the correct WEP password if any), otherwise you cannot connect to that wireless network.
