Always "connecting" wireless fault solution

Troubleshooting

Due to the declining value of wireless Internet access devices and the gradual maturity of wireless networking technology, more and more organizations and even families have begun to use wireless networking for Internet access. While enjoying the convenience and efficiency brought by wireless networks, we sometimes encounter some strange wireless network faults that can't be solved, is it a bit disappointing?

But you can never ask a professional technician to handle a small fault in Sesame. Some wireless network faults can be solved by yourself. This is not the case. Next I will contribute to the troubleshooting process of the "connecting" wireless network that I have encountered, hoping to help you!

Transient connection failure

In order to keep up with the trend of the times, the author's office specially adopted wireless routing and ADSL dial-up to access the Internet. Several laptops in the office can surf the Internet normally through wireless networks. However, I recently switched on the power of my laptop and found that the wireless network card device installed in my laptop always prompts me to "Connect ".

At that time, I was eager to find information, so after I found the prompt "connecting", I forcibly opened the IE browser to access the webpage content, and found that the network access was normal, I quickly found the desired information on the Internet. Later, every time I surf the Internet, the wireless network card device in the laptop still prompts "connecting" information, although this does not affect my network access operations, however, the "connecting" prompt is forced to appear in front of the author, which makes the author feel very uncomfortable, so the author uses a manual method to forcibly disconnect the wireless network connection, and then wants to re-connect to the wireless network.

But at this time, unexpected things happened to the author. When the author forcibly disconnects the network being connected, the laptop could not find any available wireless network nodes again. After restarting the laptop, I found that the wireless network card device still cannot find the wireless network. As a last resort, I had to restart the wireless router in the office. I thought it could solve the network fault, but the result was disappointing, and the laptop still could not find the wireless network.

Carefully investigate various possible factors

After repeatedly restarting wireless network devices, the wireless network failure still cannot be solved. The author realized that the wireless network of the Organization may encounter problems. I first carefully checked the wireless Nic device installed in my laptop and found that the signal lights of the device are working properly.

I did not feel the heat when I touched the surface of the wireless network card device by hand, and I did not smell any smell from the wireless network card device, I estimate that the wireless Nic device is working normally. Then I came to the wireless router in the office and carefully observed the flashing status of the device's signal lights. I found that the signal lights of the wireless router work normally, when you touch the shell of a wireless router device by hand, it is found that the device is not overheated. Obviously, wireless network card devices and wireless router devices are not faulty in hardware, and the problem may occur in parameter settings or system settings.

The author's office network is composed of a wireless router and ADSL device. to effectively ensure the security of the office wireless network, the organization's network administrator has logged on to the background of the wireless router device, disable the SSID Broadcast Function of the wireless network and perform WEP encryption on the wireless network. Because my laptop and the wireless router are in the same office, the distance between the wireless Nic device and the wireless router device should be very close, I estimate that such a short distance will not result in unacceptable Internet information. Since the wireless network card device always prompts "connecting" information, is it possible that the communication protocol in the laptop has an accident?

Due to work reasons, I have installed some other network communication protocols in my laptop at the same time. I estimate it is likely that the communication protocol is improperly set, resulting in the inability of wireless Nic devices to work with one mind; as a result, I immediately opened the local wireless network connection attribute setting window and deleted all other communication protocols temporarily unavailable in this setting window, then I restarted my laptop, but I still cannot find the available wireless network.

In-depth research to solve problems

So how exactly is a fault? In desperation, the author calmed down and began to carefully sort out the wireless connection process. During wireless Internet access, the wireless network card device in the laptop should be able to receive wireless Internet access signals, and be able to correctly identify the wireless network SSID name, and then match the relevant communication protocol, connect to the wireless network with the support of the corresponding protocol. Since I cannot find wireless networks in my laptop, is it possible that I encountered an error in the SSID name?

With this in mind, I entered the wireless network connection attribute setting window, and deleted the previously set preferred network directly, and added a new wireless network in the correct way, however, this still does not work. At this time, all the fault factors that I can think of have been ruled out in sequence, but the failure to find the wireless network is still not resolved. Which factor did I not think?

After my repeated efforts, I plan to re-check the wireless router. Considering that, before a network failure occurs, colleagues in the Office did not make any changes to the settings of the wireless router, theoretically, the settings of the wireless router should have no faults. However, from the perspective of actual faults, since the laptop prompts that the network connection cannot be established, the fault factors can only be found in wireless routers, wireless clients, and communication connections between them, the communication between the wireless clients and the clients has been ruled out. It seems that the problem only lies in the wireless router device.

If a wireless router fails, what exactly is the fault? To check whether the wireless router is faulty, the author immediately enters the background management interface of the wireless router device by controlling the cable and finds the "allow SSID broadcast" setting option, select the option with the mouse, save the operation, and restart the wireless router device. After the wireless router device restarts successfully, I try to search for the wireless network in my laptop again. This time, the wireless network card device quickly prompts that the wireless network connection is successful, the attempt to access the network content also succeeded, which indicates that the "connecting" wireless fault has disappeared.

Explore fault causes through symptom

However, I still don't understand why selecting the "allow SSID broadcast" setting option can solve the problem? In many cases, in order to ensure the security of the local wireless network, we often disable the selected status of the "allow SSID broadcast" setting option, it is reasonable to disable the "allow SSID broadcast" function. Shouldn't it cause a "connected" wireless fault?

I believe that it is definitely not the "allow SSID broadcast" function of the wireless router that causes a "connecting" wireless fault. It may be that the operating system of the wireless router has its own bug, as a result, the working status of the wireless network is abnormal. to verify whether the "connecting" wireless fault is related to the wireless router operating system, I enter the background management interface of the wireless router device again, disable the "allow SSID broadcast" function on the interface, restart the system of the device, and then connect to the wireless network again, it is found that the "connecting" wireless fault does not exist, and wireless network access is normal, which indicates that the wireless router operating system does have a bug.

So why does the wireless network card device in the laptop always show a "connecting" prompt, but it can access the network normally, and after the wireless network connection is disconnected, the laptop simply cannot find the wireless network?

After careful analysis, the author believes that the reason why the wireless network adapter device can access the network normally when the "connecting" prompt is displayed is probably due to the installation of too many communication protocols in the laptop. When we forcibly disconnect the wireless network, the bug in the operating system of the wireless router may lead to abnormal working status of the wireless router, resulting in the failure of the wireless network card device to find the wireless network.
