What to do if the Internet has stopped working. Internet is connected but not working. Installing a discrete network card.
Instruction
Note: if you do not know how to contact the company that provides Internet access (hereinafter referred to as provider), then the chances to solve the problem are much less, and you can immediately proceed to step 3.
Situations where the Internet is gone for no reason, happen infrequently. To begin with, make sure that everything is in order with the provider, i.e. There is no debt for the Internet, as well as problems and preventive maintenance by the provider. It is recommended to check the work of the official website of the provider - most often they can be reached even with a zero balance. If the site works, then the problem is in the payment or the provider does some work - a self-respecting provider will inform about it on the site. Call the provider and check all the payment information. A fairly common situation is when a user is sure that there are funds in the account, but in the end they are not there. Also ask the provider to check the visibility of your visibility.
If the provider does not see you - try to turn on the wire from the router (if it is turned on there) directly into the computer. If even after that the provider still does not see your MAC address, then most likely the problem is in the wire AFTER the router or in the RJ-45 connector. In this case, dialing the wire and a new crimping of the wire is required, it is recommended to talk to the provider about this problem.
In case the provider sees ONLY your computer - most likely the problem is in the router. Try resetting the router to the factory settings, for this, use the instruction manual. If the reset does not solve the problem - most likely the router is faulty, try replacing.
If the balance is in order, the provider sees your MAC address and there is no preventive work on his part - proceed to the next step.
Now check availability local network. To do this, press Win + R on the computer, enter the word "ping", and then enter the address of your nearest device. Most often it is a router: if the wire from the computer goes to it, then you need to write its address. The most common is 192.168.0.1 or 192.168.1.1
If the packets do not go (ie, the lines do not appear with an interval of approximately 1 second) - check whether your router is turned on, check the condition of the cable and the reliability of its connection to the connectors of the computer and the router. If everything is in order, but packets still do not go - restart the router. If the packages started to be successfully delivered to the device, then everything should be fine, the Internet disappeared because of this.
If not - look at the back of your system unit: most often in the place where the Internet cable is inserted, there is a green light bulb. It does not burn and does not blink - the problem is in the network card itself or its drivers. Try to reinstall the drivers, as well as check its external condition - it could easily burn.
If the light is on, but the packets still do not go, or the packets are normally transferred to the device, but there is no Internet - most likely the problem is in the software settings of the computer.
Open the network control center and shared, find your active connection, then go to properties, then - TCP protocol version 4. With the standard and most common connection scheme (provider - router - computer), the router most often distributes all the necessary addresses for normal operation via DHCP. If you have written any settings in the fields - just in case, write them down, then select the automatic IP parameters, and in the DNS fields write 8.8.8.8 and 8.8.4.4. This is a Google server. They are reliable and always work.
If you are completely unaware of the scheme of anti-virus utilities, the architecture of the organization of network settings and the principles of operating systems - contact a specialist, because subsequent actions without proper knowledge are not recommended.
When nothing helps and there is still no Internet - this may be a consequence of the activity of viruses. First you can try to restore the system settings. To do this, you need the AVZ utility, you will have to download it on another device that has access to the Internet (preferably from the official website z-oleg.com, it is often the first in the search). When you have an archive on your hands, it’s enough just to unpack it, because the program does not require installation, and run the avz.exe program. After click on the "File" in the menu bar, then - "System Restore."
Check the items on the image, then click "Perform marked operations". After that, check access to the Internet.
If you did everything carefully, but still nothing helps - it is recommended to call a specialist, because The problem can be both in the registry of the operating system and in the firmware of the router. At least you can tell the master everything that you have already tried.
Over the past 10 years, the Internet has rapidly entered our lives and every home where there is a computer.
Now, not a single user working at a computer can submit it without connecting to the Internet. Indeed, on the Internet you can find almost everything. Watch movies, sports broadcasts, listen to music, play online games. Find the information you need on any topic and download it.

Internet connected but not working
The name of the post turned out strange, but everything looks exactly like this:
- The computer is connected to the router, but the Internet on the computer does not work;
- When the cable is connected to the network board, the connection indicators on the board do not light up;
- Internet is guaranteed to work. If you connect another computer or laptop to the same cable, you can easily access the Internet.
Similar symptoms indicate that the integrated network card has failed in the computer.
Consider the problem and its solution on a specific example. We connect the network cable to the computer, but the Internet does not work, the computer does not signal that the cable is connected. See if the computer “sees” the network card ( network card, network adapter, "Network card"). To do this, you need to see the list of devices in the Device Manager.
Step 1. Go to the main menu by clicking on the Start button\u003e then right-clicking on the Computer\u003e item in the context menu, select Properties.
Step 2. In the window Properties of the system go to the Hardware tab and click on the button device Manager.
Start the device manager
Device Manager has started. As expected, there is no network card in the list.
To once again make sure that the case in the gland, and not in the software, on the computer was loaded, from the CD-ROM, operating system . After ubuntu downloads, network cards were also not detected.
Conclusion: the integrated network card is out of order. Elements of the integrated network card are located on the motherboard, i.e. integrated network card cannot be replaced without changing the motherboard. However, we can install a discrete (external) network card.
Installing a discrete network card
After you open the system unit, it is advisable to clean it from dust (). After that, you can safely proceed to the installation of a network card.

The network card can be installed in any free PCI slot. On budget motherboards PCI slot can be only one. In the particular case of the slot three and the network card will be installed in the upper PCI slot.
Network card will install in the top PCI slot
Step 1.
Step 2.
Step 3. Fix the bracket with a screw. If there are no spare screws, you can borrow one screw from the housing cover or from the power supply.
Closes the case of the system unit, connect all the necessary cables and turn on the computer.
Installing NIC Drivers
If the computer is running the operating system Windows 7, then the installation of drivers will be automatic. In a particular case, an operating system is installed on the computer. windows system XP, so driver installation was required.
Originally posted . Let me explain that the Ethernet controller is the network card.
