Router and wireless network card connection failure analysis

When using a vro, the same brand of wireless network card will be used by the way, which is the best for compatibility and can effectively improve the transmission speed of the wireless network, but in the process of use, different faults may also occur.

Currently, wireless network interfaces are mainly PCI and USB interfaces. No matter which type of interfaces are used, they must be inserted in place to ensure that the network adapter is in close contact with the computer slot or port. If the insertion is not in place, the wireless network card cannot be identified by the system.

Therefore, when you encounter a fault that cannot be identified by the wireless network card, check whether the network card is closely connected to the computer based on the interface card type.

1. for wireless NICs with PCI interfaces, it is necessary to check whether the PCI slots on the computer motherboard are suspected of being swollen. If the PCI slots are split, even if the wireless network card is barely inserted into the slot, it may be caused by external vibration, resulting in a deviation from the position of the wireless network card and the PCI slot, or even the network card is loose. In this case, you 'd better re-insert the wireless network card into another PCI slot. when inserting the wireless network card, you must ensure that the golden finger of the wireless network card is in close contact with the slot.

2. If you are using a wireless network card with a USB interface, you 'd better check whether the wireless network card has slipped down from the USB port of the computer or whether the wireless network card has a tendency to fall down, in this case, the USB port on the computer is no longer in close contact with the wireless Nic. At this time, you can also change the USB port of the computer to re-insert the wireless network adapter. Of course, to avoid damage to the USB port of the computer, you can use a USB extended cable to connect the wireless network adapter to the computer.

3. If the driver of the wireless network card is not properly installed, or the driver of the wireless network card is damaged by viruses or other incorrect operations, the computer system does not recognize it sometimes, so when the wireless network card cannot be identified, you 'd better check whether the original driver is installed, alternatively, check whether the NIC driver is the latest version. Before installation, clean and uninstall the old driver from the system to avoid resource conflicts between the drivers of the new and old versions.

When installing a wireless network card with a USB interface, if the USB port of the computer's motherboard is set to disabled in advance, No matter what measures are taken, the wireless network card cannot be correctly identified, go to the CMOS parameter settings page and check the USB Controller option settings to check whether the USB port is enabled on the computer motherboard. If this option is set to Enable, it indicates that the USB port on the computer has been opened. If it is set to Disable, it indicates that the USB port on the motherboard is not activated.

If you are using a wireless network card of the PCI interface, you should pay attention to whether the network card has a resource conflict. If yes, the system will not be able to identify the wireless network card correctly, open the System Device Manager window, view the NIC icon status in the device list, and check whether the NIC icon has a yellow question mark. If yes, what is yellow? Or! It indicates that the wireless network card has a resource conflict with other devices. Although the wireless network card driver is correctly installed, it will not be recognized by the system.

If the above measures have been tried, or the wireless network card cannot be identified, it is necessary to check the wireless network card's own problems, whether the quality of the network adapter is faulty, the USB port of the wireless network adapter, and whether the network adapter is damaged.
