The network card on the motherboard asus does not work. The network card is not working.
Through the computer, which is especially bad, if all activities are closely related to its disposal. Let's figure out how to fix the problem, if the card does not fail, but its functioning has problems.
Usually LAN-equipment problems are solved through settings
External Damage
There are two types of maps by location: external and internal. In case the device is installed separately, check whether it is firmly inserted in the slot and whether the Internet wire is well placed in the slot. Probably, the problem lies in the damaged contacts inside the connector or the cable itself is damaged from the provider.
In a situation where the adapter is damaged, you need to replace the port or purchase a new part. If everything is fine on the outside, it means that the problems are related to the downed settings.
Map settings
Can not the computer see the network card? Go to Device Manager, select Network adapters from the list. Now in context menu click "Update Hardware Configuration" to have the system find the device and add it to the list.
After that, we will find out if the adapter is installed correctly - if the yellow exclamation mark is on the icon with the name, it means that the drivers function incorrectly or are not suitable for the device. Correct it with the help of such actions:
- Open the properties of the specified part, the "Driver" tab.
- Activate the "Rollback" function so that the system begins to recycle the previous version of the configurations.
If the situation has not changed, you need to update the drivers - to do this, use the button with the same name, located in the properties menu. With the help of automatic search, the computer will automatically find the files, but if they do not, download and install them manually.
The network card does not work, although it is properly connected? When there is still no signal from the provider, it is advisable to check the connection parameters.
Proceed as follows:
- Open Control Panel, Network and Internet, select Network Management Center and sharing.
- If you see that there is a red cross on the connection diagram, click on it, after which the system will analyze the parameters to identify the problem.
- Follow the diagnostic instructions to ensure that the computer has resolved the problems with the network connection.
An idle network card will not allow you to go online or local area network, if you connect to them through the network adapter. Network cards are built-in or external. If the card is external, see if it is fully inserted into the slot. Also check the density of the network cable connection to the adapter connector. If these options do not work or you have a built-in network adapter, it's probably the system settings.
If the Internet stopped working. In the task bar, check the connection status. If there is a red X on the Internet access icon, then there is no connection. Try to turn it on. To do this, click on the Internet icon and select "Network and Sharing Center". Click on the red cross in the network connection diagram. A diagnostic program will start, which will fix the problem and turn on the AC adapter if it is disabled. Driver Failure. If the network card drivers are incorrectly installed or they were damaged, you should reinstall them or make rollback up to the last working state. To do this, click "Start", right click on "Computer" and from the list of commands select "Properties". In the menu to the left, open Device Manager. In the "Network Adapters" section, your device can be marked exclamation point, which means its malfunction. Double click on the adapter, select the "Driver" tab and click "Rollback".
Make sure that the problem is in the network card. If the diagnostics described in step 1 does not reveal problems with the adapter, it may be the case with the provider or a technical failure on the line. Regularly update the drivers and carefully store the disc from the motherboard - this will help you quickly solve problems with the network card. External cards can be checked on other computers to identify the cause of the problem.
A frequent and common phenomenon is the error of the network card. Immediately or after some time, the Internet disappears and an unpleasant message appears on the system that the network cable is not working properly or connected incorrectly. Users, usually, begin to check the cable, connection, call to the service center of their provider in search of a solution to this problem. On the occurrence of such an error, several factors affect and often, the network card is not at all, the reasons lie in the other ......
A frequent and common phenomenon is the error of the network card. Immediately or after some time, the Internet disappears and an unpleasant message appears on the system that the network cable is not working properly or connected incorrectly. Users, usually, begin to check the cable, connection, call to the service center of their provider in search of a solution to this problem. On the occurrence of such an error, several factors affect and often, the network card is not at all, the reasons lie in the other.
Let's immediately determine the range of reasons why such an error may occur. Firstly, of course, it can be a trivial way to fail. This can be affected by the quality of the computer equipment itself, and the quality of the network card itself, it all depends on the manufacturer. In addition, its operation and external factors may affect its operation, as well, not an accurate attitude, an incorrect installation, when a user of a personal computer attempted to insert a card into the PCI slot, while damaging some contact or the external surface of the network card itself, etc. The PCI slot is not working properly, which is the case, then just try to insert the network card into another slot.
Secondly, the simplest and most common variant of a malfunction is the lack or incompatibility of network driver or incorrect installation of them. In this case, the drivers are deleted and replaced with new ones. Thirdly, a real damage to the network cable, through which the signal is delivered to your computer. In this variant, there may be several causes of damage from mechanical to industrial reject. The option of eliminating this malfunction, there can be only one - from another source of signal, for example, take the computer to a neighbor and connect it there to the Internet. If the case was only in the cable, then the computer can safely connect to the network. Then the reason is not in the network cable, and not in the RJ45 type connector (you need to pay attention to it first), but in the network card itself.
Now let's talk about another reason, which I personally encountered, on my own experience. On my computer there is an integrated network card (built-in), it worked flawlessly and claims to it did not arise. Recently I purchased a removable network card and tried to install it on my computer. Before that, I used it on another computer that did not have an integrated network card. Everything worked fine there, but as soon as I inserted it into my computer, there appeared an inscription on the network adapter icon "The network cable is not working properly or connected correctly" and a fat cross indicating that there was no connection to the Internet. But struck by the fact that the map in the system unit flashing lights, and all the signs that she works. With this network card as a device, it was safely identified in the BIOS, operating system Windows7 automatically installed the driver and issued a message that the equipment is ready for use and there are no problems with it. Device Manager, unequivocally stated that everything is in order, the equipment is turned on and working normally. First of all, there was an idea about the damage to the network cable. By transferring the cable to an integrated network card, the Internet appeared immediately. I had to continue dancing with a tambourine, around this network card. did not lead to the desired result, the system continued to issue a message about the cable fault, and that it is not able to eliminate this situation. The decision came by itself, and it turned out to be simple and not difficult.
Solution of the problem. The first thing I did was to disable the integrated network card in the "Device Manager", delete the previously installed drivers, on a non-working network card. After that, re-installed the card in the PCI slot in the system unit and started the computer. The operating system identified the equipment, and installed it. At the next stage, I started Device Manager (Start - Control Panel - Device Manager) and right-clicking on the device ( network adapters - for example, Realtek RTL8139 / 810x Family Fast Ethernet Nic). Going to the Properties - Advanced menu, highlighted the "Link Speed / Duplex Mode" section and made changes on the right in the "Value" window, and set "100Mbps / Full Duplex".
After that, the connection to the Internet was restored, and the operating windows system 7 stopped sending a message indicating that the network cable is not working properly or is not properly connected. Thus, the error in the operation of the network card was fixed. Yes, I almost forgot, in the properties of the network card in the tab "Power Management" you need to uncheck the "Allow this device to be turned off to save power".
