All sub bounties for network adapters without realtek

Didn't see what it meant?! Message me! Give me a screenshot and I'll see it!

Device Manager becomes blank for the solution category: Virus Control.

For some reason, the device manager goes blank, the little speaker in the taskbar is missing, the network connection is lost, and all devices are unviewable. Presumably due to corrupting system files or registry (not my own computer), then repairing the system should be able to cope with it. Here's how:

Start-> run, enter regsvr32 and regsvr32 respectively, and press enter.

Put the system installation disc into the CD-ROM drive, start -> run, enter cmd first, and press enter. Then enter SFC ScanNow and press enter, and the system will automatically replace the damaged system files.

In some cases, the above methods may not work, so it is recommended to reinstall the system. Remember to back up your important data.

You first run getmac under cmd, see if it can be displayed normally, if not, it is likely that your network card is not plugged in or broken, if it can be displayed normally, it may be that the driver is not installed.

BIOS issues.

Look for the onboroad lan item in BIOS, there are 3 items below it, set this total item to disable (AUTO that place below), OK?

on-chip lan [auto]

on board serial port1 [3f8/irq4]on board serial port2 [2f8/irq3]on board parallel port [378/irq7]

Check the NIC Remove the network adapter, reboot - discover new hardware - install drivers.

Situation 1: The display mode is incorrect1, open the controllable panel (win+x, click [Control Panel] in the pop-up menu); 2. Modify the "View Method" in the upper right corner to [Big Icon Mountain Late]. Scenario 2:

The internet is not connected right now.

Can this problem be solved.

Replugging the network cable causes the computer network cable to be unplugged, which is likely to be caused by the loosening of the connection part of the network cable crystal head after you have moved the computer or the computer has been placed for a long time, which is the most common. We can try to reinsert the network cable connector into the network card interface of the computer. Note:

Plug in the network cable normally, and you can hear a click when you install it, which means that the installation is correct. What does it mean that the network cable is pulled out 2, if the crystal head is faulty If you plug and unplug the network cable again, the network cable is still unplugged, this situation may be the fault of the network cable crystal head, it is recommended to change a network cable to try, if the problem is solved, then the crystal head of the network cable is faulty. What does it mean that the network cable is pulled out 3. Software problems If the above two methods still do not solve the problem of the network cable being pulled out, then it is likely that the software is partly caused by the problem, and the software mainly includes network card drive, ARP attack, etc.

For software problems, we can check the network card driver, the most respectful thing is to update to the latest driver, the specific network card driver update, you can use the driver wizard tool ** update. ARP tools may be a virus in the computer, or caused by a tool, this situation will cause the network card to be good and bad, often intermittently prompt the network cable is unplugged, in this case, you can use light guard, 360 security guard and other tools to detect whether there is an attack on the computer and a virus. What does it mean that the network cable is pulled out There are some other factors, which may also lead to, such as the use of routers, cats and other equipment, and the router or cat fails, it will also cause this kind of network cable to be pulled out, but this situation is relatively rare, of course, if the motherboard is damaged by lightning, or the motherboard itself has a problem, there is also the possibility of this problem, but the last problem caused by these factors is very rare, if you fail to solve the problem according to the above three situations, It's a good idea to take out the computer and the routing equipment.

Summary. There is no realtek in the network adapter

The computer network cable is unplugged, which is likely to be caused by you moving the computer or the computer has been placed for a long time, and the connection part of the network cable crystal head is loosened by the guard, which is the most common. We can try to reinsert the LAN cable plug into the network card interface of the computer.

The WLAN status does not exist.

You re-unplug this network cable, and then plug it back in to take a look and give it a try, it may also be this problem.

My laptop is not plugged into the network cable, and it is connected to wifi.

You either want to change to another wifi and try it.,Your notebook is more difficult to do.。

Wait a minute. The problem is that he can't even show wifi.
