Network Management Manual: answers questions about Wi-Fi connection failures in Wireless Networks

For wireless network technology, many of us do not know what problems occur when the connection fails. How can we troubleshoot and diagnose the problems? Here we will answer your questions.

When using wireless networks at home or in public, the network may be disconnected without warning. For us, I am afraid it is no more frustrating than this. Of course, this is also a very common network problem. Next, this article will detail the problems that may occur and tell you how to solve them.

Wi-Fi connection failure Q & A 1. Wi-Fi radio interference

Radio may come from many consumer electronic products, such as cordless phones, Bluetooth headsets, microwave ovens, and even electric garage doors, which may interfere with the normal operation of Wi-Fi wireless signals.

Solution: Remove or stay away from these devices. If the wireless signal is restored or increased, the root cause of the problem is found.

Wi-Fi connection failure Q & A 2. Insufficient Wi-Fi network radiation

Even if there are no other interference devices, it may be that the Wi-Fi network has insufficient radiation coverage, resulting in unstable wireless networks. As you know, the connection status of the Wi-Fi network is closely related to the distance between the terminal and the AP.

Solution: Minimize the metal obstacle that affects the link or shorten the distance from the AP. A more feasible solution is to consider installing an antenna to achieve better wireless transmission performance.

Wi-Fi connection failure Q & A 3. Link to the wrong Wi-Fi network

If there are two Wi-Fi networks with the same network name in your wireless network environment, you may be linked to the wrong network and affect your normal internet access. In this case, signals may interfere with each other or the radiation range is insufficient. In addition, if the other network is disabled, it will also affect your computer's Internet access.

Wi-Fi connection failure Q & A 4. The network driver or firmware is not upgraded in time

Each computer that connects to a Wi-Fi network must use its built-in network module and related drivers to achieve wireless Internet access. The driver affects the performance of Wi-Fi hardware. In addition, the wireless router and the firmware responsible for access are the same as those of the driver, which affects the wireless Internet access function.

Solution: uninstall outdated drivers and firmware to download and install the latest driver for wireless module components on the official website.

Wi-Fi connection failure Q & A 5. software incompatibility

If your computer has no wireless connection from the very beginning, it is likely that your computer has installed incompatible software. These include operating system patches, operating system service components, and other software that may affect the system network.

Solution: record the software every time you upgrade or install the software, uninstall the incompatible software, or simply restore the system.

Wi-Fi connection failure Q & A 6. Heavy Load on routers (access points)

In the past, some people reported that the excessive load on routers or access points will affect the speed and quality of wireless Internet access. The main causes of router overload are: online games, BT downloads, or a large number of computers connected to the network. Theoretically, a large volume of data transmission usually causes a temporary disconnection of the router. In addition, if the temperature of the router is too high, it may also cause a disconnection.

Solution: A good ventilated environment is required for the router installation. If the router is not suitable for your use (such as requiring high data transmission capabilities), consider changing the router.
