1. Some cases are not connected at all 2. Some are connected, but they are connected incorrectly. 3. Some are connected, but the bios is turned off 4. Some connecting lines are too poor and interfere greatly, so USB devices can't be used, or pick the device. 5. Some interface boards have problems. Same as above 6. The power supply is insufficient due to the reasons of 4 and 5, and the equipment is selected. Once we know the reason, we can solve it. 1. Find the manual and check whether it is connected correctly, 2. Find the manual and check whether all USB devices are enabled in the bios 3. If the equipment is picked up, try to change a set of cables, or change a set of cables and an interface board (the interface board attached to my asus motherboard is of good workmanship.)
It is estimated that the port is not recognized after the change. You can delete the driver software, reinsert the wireless network card, and install the driver.I have had similar problems before and solved them in this way.Try it.
