When using a router, it’s common to pair it with a wireless network card from the same brand for optimal compatibility, which can effectively boost wireless transmission speeds. However, various issues may still arise during use.
Currently, wireless network cards mainly come in two interface types: PCI and USB. Regardless of the type, the card must be inserted properly to ensure tight contact with the computer slot or port. If it’s not fully inserted, the system will fail to recognize the wireless network card.
Therefore, when you encounter a wireless network card not being recognized, check whether the card is securely connected to the computer based on its interface type.
1. For PCI interface wireless network cards, you should check whether the PCI slot on the computer motherboard is at risk of being over-expanded. If the PCI slot is cracked, even if the wireless network card is forced into the slot, external vibrations can cause the card to shift from its proper position in the PCI slot or even become loose. In this case, it’s best to reinsert the wireless network card into a different PCI slot, ensuring the card’s gold fingers make tight contact with the slot.
2. If you are using a USB interface wireless network card, check whether the card has slipped out of the computer’s USB port or if it has a tendency to sag downward. If so, this indicates that the USB port and the wireless network card are no longer making a tight connection. At this point, you can also try switching to a different USB port on the computer to reinsert the wireless network card. Of course, to avoid damaging the computer’s USB port, you can use a USB extension cable to connect the wireless network card and the computer.
3. If the wireless network card driver is not installed correctly, or if the driver has been corrupted by a virus or other improper operations, the computer system may sometimes fail to recognize it. So, when facing a wireless network card recognition failure, you should check whether the original driver is installed, or check if the driver is the latest version. Before installation, thoroughly uninstall the old driver from the system to prevent resource conflicts between the old and new versions.
When installing a USB interface wireless network card, if the computer motherboard’s USB port has been preemptively set to disabled, no matter what measures you take, the wireless network card will not be recognized correctly. Enter the CMOS parameter settings page and check the setting value of the USB Controller option to see whether the computer motherboard has enabled the USB port. If this option is set to Enable, it means the computer USB port is activated. If it is set to Disable, it means the USB port on the motherboard is not activated.
