Windows computer wireless network connection but can not be connected to the network reasons and solutions, I believe that many inexperienced people do not know what to do, so this paper summarizes the causes of the problem and solutions, through this article I hope you can solve this problem.

Recently, many students have e-mailed questions about many wireless network connections but can not be connected to the Internet, such as:

Q1: the wireless network has been unstable these days, sometimes it can be used and sometimes it can't be used, and it won't take long to get on it. In many cases, the wireless network shows that it is connected, and the signal is very good. However, the Q or the Internet can not be used, and then according to the status of the router, the IP address and DNS address have been modified, but still can not. Very depressing! Now it is possible for the router to pull the network cable directly, but it can not be used wirelessly, showing that it is connected, but it cannot be connected to the network. Both IP and DNS addresses are obtained automatically. I checked the routing log today, and it shows

Q2: last night, I inadvertently opened the wireless network wi-fi and found two unencrypted wireless networks. Although the signal was poor, they could still link to the Internet, but today, when I opened the link, there was a yellow exclamation point. What's going on? I could have linked it last night.

Q3: I have two laptops and one desktop at home. Yesterday, after setting the password for the wireless route, one laptop could access the Internet normally, but the other laptop could not access the Internet. When setting the ip address, if you automatically get the searched network is restricted or unconnected (there is an exclamation point in the network connection), if you fill in the ip address and connect to the signal, it is also good, but you can't get on the Internet, please help me!

Q4: I was always getting IP, but then I set it manually and showed that the wireless network was connected, but even if I couldn't get on the Internet, I couldn't get on the QQ. Ip also does not ping, showing that media disconnected360 flow control shows that there is occasionally 0.3K 0.1K 0.04K flow. IE fixed it. It doesn't work.

The following are several common reasons to investigate the reasons why the wireless network connection can not be connected to the network and the corresponding solutions.

First, check whether the password is wrong

When entering the wireless connection password, if the password is long, you may enter the wrong password, so it is recommended that you enter the password again. If possible, enter the password directly using copy and paste. When copying and pasting, be careful not to select extraneous characters. Adding one or two extra spaces is the most common mistake.

Whether the wireless router has been bound to the MAC address

In order to prevent others from surfing the Internet, many home users have set up wireless Mac address filtering, but when the computer or wireless network card is replaced, it will not be able to access the Internet, so you need to add a new MAC address to the router settings.

Third, whether the service setting is completely correct

Check the service settings on the computer side, such as DHCP Client and WirelessZero Configuration services are not started, it will lead to abnormal use of the wireless network. If DHCP is not enabled, the computer that uses the automatic allocation of IP cannot automatically configure the IP address.

4. Whether the assigned IP address is set correctly

Wireless networks use manually assigned IP and DNS addresses, which need to be set in the wireless connection properties under Windows. Unlike Linux, Windows cannot set different IP addresses for different wireless networks, so when switching among multiple wireless networks, it is easy to fail to access the network using manually assigned IP.

5. Whether the driver is suitable for the current network card

Most of this happens when you use a wireless network card for the first time. If you use Windows 7, you will usually download and install the correct network card driver automatically. But in extreme cases, the downloaded driver may not be suitable for the network card, so you may need to download the driver from the manufacturer's home page.

6. Whether the necessary patches have been installed

Under Windows XP, you need to install a patch to support WPA2-PSK encryption, so if the router uses this encryption and you have not upgraded to XP SP3, install the KB893357 patch.

Check one by one according to the above steps, the problem that the wireless network can be connected but cannot be connected to the network can basically be solved, but there may also be other reasons. if you still can't solve the problem, then please follow the following steps to check and repair.

The network connection settings are automatically repaired by the system

1. If the wireless indication in the lower right corner of the laptop desktop indicates that the network is not working properly if the exclamation point shown below appears.

2, according to the right wireless instructions, open the network and sharing center, see Windows 7 in the network diagnosis determined that the network is not recognized but can be connected!

3. Click which red cross to let the system automatically detect the cause of the problem

4. Let the system repair automatically after the system test report appears.

Use automatic acquisition of IP address to repair network connection

If the fault can be detected and repaired here is the best, but if after repairing the system, still can not access the Internet, then we go back to the network and sharing center, find to change the wireless card properties, and right-click the wireless card properties.

1. Find the IPv4 protocol.

2. The current network is a manually configured IP address.

3. Change the setting to obtain the IP address automatically.

After reading the above, do you know the reason why the windows computer is connected to the wireless network but can't get on the Internet and how to solve it?
