In contact with
Before proceeding to find out why Wi-Fi or the Internet does not work, you should know (especially for those who have just purchased a Wi-Fi router) that it is not enough just to connect the provider's cable to the router, it still needs to be configured (set up the Internet and Wi-Fi network ). All the methods described below are valid if Wi-Fi and the Internet worked for you before, and then suddenly stopped or you cannot connect a new device to Wi-Fi. For convenience, I divided the article into two parts, the first is devoted to the inability to connect to wireless network, the second part will answer your questions if you are connected to a Wi-Fi network, but there is no Internet.
Unable to connect to Wi-Fi network.
Rebooting the router.
The first thing to do if you have problems connecting to a Wi-Fi network is to restart your router. To do this, simply disconnect the power supply from the router and reconnect after a few seconds. After 1-2 min. the device will boot up, then try to connect to the wireless network again. To avoid in the future similar situations, I recommend updating the firmware of the router (maybe the manufacturer knows about the problem and fixed it in the new firmware).
Enabling Wi-Fi module on a laptop.
Check if Wi-Fi is enabled on the laptop, I won’t turn around, I described all the ways to enable Wi-Fi in the article How to turn on Wi-Fi on a laptop .
Change the wireless network mode.
If you are trying to connect a device (laptop, smartphone) that is more than 5-7 years old, please note that it may not support the modern Wi-Fi mode - n. Therefore, you need to switch the router to the operating mode that is supported by the device or enable mixed mode b/g/n. More details about Wi-Fi operating modes are described. In order to switch the wireless network mode, you need to go to the web interface of the router, go to the Wi-Fi settings and select the appropriate mode.
Delete duplicated SSID.
One of the possible problems of not being able to connect to Wi-Fi is the duplication of the Wi-Fi network name (SSID). Suppose you come to your friends, they have a Wi-Fi network called "Home", you have successfully connected to it. Time passed and already at other acquaintances or at home you met the same network name. The laptop (this also applies to tablets, smartphones) tries to connect to the network using the previously saved password, but it fails because a new password is used for this name. To solve this problem, you need to remove from the list of saved WiFi networks matching network.
To do this, right-click on network icon in the lower right corner of the screen and select "Network and Sharing Center".
After that, you will see a list of saved wireless networks. If you see that the network you are trying to connect to is on this list, you need to remove it from this list. Select a network and click the "Delete" button. After that, you will need to enter a password to connect to the wireless network.
No Wi-Fi Internet.
Internet payment verification.
The simplest thing that can happen when the Internet is not working is that it's time to pay for it or work is underway at the provider. To clarify the situation, call the provider and check if you have a debt for the Internet and whether work is being done on the line.
Static IP address.
One of the problems of the Internet not working, maybe - the registered static address is not with the network settings that are needed. In this case, I recommend using automatic network settings acquisition. To do this, you need to get into the Network and Sharing Center. One way to do this is to right-click on network icon in the lower right corner of the screen and select "Network and Sharing Center".
Another way is to use hot keys
It doesn't matter which of the methods you used, the result will be the same - the Network Connections window will appear on the monitor. Next, you need to double-click on the wireless connection, In the status window that opens, select "Properties" in the properties window "Internet Protocol version 4 (TCP / IPv4)"
Router problem.
The Internet may not work due to a router failure, the easiest thing to do is to restart it. There are situations when the router resets the Internet settings, in which case it is necessary to connect to it via the web interface and re-enter the Internet settings, in order to experience fewer problems with the router in the future, I recommend updating its firmware.
Conclusion
In this article, I described all the ways I know to solve problems with Wi-Fi and the Internet. If these methods did not help you, you can describe the problem in detail in a comment and I, together with the readers of this site, will try to help you.
Internet connection problems can occur under various circumstances. The cause may be cable problems, incorrect modem or router settings, or problems that arose directly from the provider providing Internet access.
All problems, with the exception of the last one, can be fixed independently. To begin with, the main thing is to understand what specifically caused the malfunction, further actions will depend on this.
What means
Often when you turn on the device, you may find that there is no connection.
The following signs indicate this:
- error "getting an ip address" when the device tries to create a connection, but in the end nothing happens;
- appropriate WiFi router or modem signals;
- error "no WiFi connections available";
- browser message "server not found".
The list contains the most common symptoms. The presence of one of them indicates that there has been some kind of failure in the network settings or hardware. To eliminate it, we first find out the cause.
Causes
If your device works via WiFi, then first of all you need to check the router.
In this case, the reasons may be the following:
- failures in the power supply of the router associated with overload or cable defects;
- problems in the software (for example, the wireless connection driver has crashed);
- malfunction of the router itself (the contacts on the microcircuit burned out, the socket was damaged, the firmware flew off).
The same problems can occur with a modem and a wireless network adapter (most laptops have it built-in). Often, an error can occur in the operation of the program provided by the Internet service provider. But the faults don't necessarily originate in the Internet connection hardware.
Causes not related to the modem and router:
- Internet provider blocked access to the network (services not paid);
- a malfunction on the provider's side (scheduled work, disconnection, errors on the server);
- the cable is connected incorrectly (for example, installed in the wrong socket);
- software crashes.
Having figured out what became the cause, you can begin to eliminate them.
Solutions for "no internet connection" error
The first thing to do is to let the computer solve the problem on its own. Find and right-click on the network icon or WiFi access icon in the lower right corner of the screen and select Troubleshooting.
After checking, a notification about the results will appear in the window that appears. Sometimes such actions immediately solve the connection problem, but if the system has not detected any problems, you will have to find out on your own why there is no Internet connection.
Do the following:
- check all connected cables and the sockets in which they are located (the modem or router must be connected to a working telephone line, as well as correctly installed to your computer or laptop);
- reboot the router or modem, or reset their parameters with the button (in extreme cases, you can turn off the power for a few seconds);
- check the additional software for the modem or router (usually comes with a driver disk).
However, the problem may not always be so simple, and much more serious actions will have to be taken to solve it.
Video: what to do if there is no Internet connection
Change the way you connect to the network to Dynamic IP
An IP address is a kind of user passport for accessing the Internet. Changing the connection method is necessary in cases where the computer can directly connect to the network, but gives an error through the router, or does not connect at all.
This may be due to an address conflict.
Procedure:
- open the properties of the network card (through the control panel in the start menu, or through the network icon in the lower right corner);
- a properties window will open in front of you, select the “Internet protocol” item in it, right-click again and select “properties”;
- in the window that opens, change the IP address or check the box "Obtain an IP address automatically"
Changing the IP address of the router
The router is only involved in the work local network and does not go beyond its limits, so it can be assigned absolutely any IP address. However, this does not exclude the possibility of IP address conflicts.
Procedure for the routerTP-LINK:
- enter "192.168.1.1" in the browser address bar;
- after successful authorization, a tab with router settings will open, in the “Network” menu, select “LAN”;
- in the center of the screen you will see a field with an IP address, change it to the one you want and reboot the router.
MAC address cloning
A MAC address is a unique identifier for a network card. Meeting two identical MAC addresses at the same provider can cause errors and lead to the fact that one of the users will not be able to connect to the Internet.
The problem can occur both in the address of the router and in the address of the network card of the computer.
For the first case, you must do the same as for changing the IP address of the router.
After you have entered the configuration service, different actions follow for different routers:
In order to change the MAC address of a computer or laptop, you first need to:
- get to know him. In the start menu, find the "command line" in the "Standard" tab or enter cmd in the search box and run the application found;
- in the black window that opened in front of you, enter "getmac" and press the "enter" key;
- your MAC address will appear in the window;
- now go to "Network Connections" through the control panel in the "start" menu or by right-clicking on the icon for connecting to the Internet. In the "wireless adapter settings" submenu, select the desired adapter and right-click on it.
- open the "Advanced" tab and click on "Locally Administered Address" (may also be called NetworkAddress). In the "value" field, enter the address obtained through the command line, and click "OK".
Change MTU (Maximum Allowed Packet Size)
maximum transmission unit– maximum packet size of data transmitted over the network.
Designated for:
- the need to reduce the time for information transmission in case of packet loss or its defects;
- reducing the waiting time to send subsequent packets;
- insufficient for large blocks of information network buffers.
For regular user the need to change the value appears extremely rarely, but if the connection problem has not been resolved, and there are no other possible options, then you have to get here.
You can set the packet size:
- via the command line (using the ifconfig command). By default, it has the largest possible size in order to achieve maximum performance;
- in order to change it, go to the command line and enter the following:
- ifconfig fddiO 172.16.16.1 netmask 255.255.255.0 mtu 1500 where the last number specifies the maximum allowable size package.
Any connection problems on your side can be fixed with your own hands, but sometimes unforeseen situations happen that so many specialists can handle. If this article did not help you, try contacting your ISP for help.
There comes a time when? Read about it in another article.
Today I will consider a situation that users of operating systems very often face. Windows 7 And Windows 8. The essence of the problem is as follows, there is a network connection, but Network and Sharing Center writes that the Network without access to the Internet, the network icon in the tray has about a clock Exclamation point. In this case, in fact, the Internet may even be available. There may be several reasons with different scenarios. Let's take a closer look at each of them.
With the proliferation of smart home devices, online gaming platforms and video streaming services, maintaining a strong internet connection in your home is more important than ever. If you're experiencing lag while playing League of Legends or downloading music forever, there's a good chance the problem is on your end and not an ISP issue. Before scheduling a service call with your cable company, check out our Internet connection troubleshooting tips.
Can you ping? This sends small packets of data to the target site and measures how fast your connection is in milliseconds. If the test was successful, you will see the results over time. Keep in mind that not all websites accept pings. If you still can't get results, you may have a problem with your modem or router, or the problem may be at your service provider's end. If there are no lights at all, the router is probably disabled or turned off. Unplug the power cord and plug it back in after a minute or two.
But first of all, if you are connected via modem, router or ONT optical terminal- I would advise reload it. If, after rebooting the device, access to the Internet resumed, the problem is definitely in the router itself, its settings, or the provider's network (sometimes this happens). In this case, we reset the router with the reset button, set it up again and check. If anyway after a while a message appears that Network without Internet access- try another router to check.
Make sure the power switch is in the On position. If the router still won't turn on, you may have a faulty power adapter, a faulty power strip, or a fried router. Check your status. If you have a modem and router, make sure they are working properly. Wait for the modem to come back online before restarting the router. On most routers, this should be green and may flash. If there is no activity, turn off the router. Disconnect and reconnect each cable, making sure that each cable is correctly installed in the correct port.
1. WiFi network without Internet access
This is the most common situation. The reason for this problem is most often the following. The vast majority of users are not aware at all what is an IP address
and believes that for WiFi connection just enter the network security key. In most cases, this may indeed be enough, but not always. If on WiFi router disabled protocol DHCP, then you can easily connect to the network, but here IP address your wireless adapter on your laptop, tablet, or smartphone will not receive. Accordingly, you will not have access to the Internet, although the network is actually connected, but only partially.
By the way, this is also possible with a wired connection - the cable was plugged in, but the address was not received.
What to do? Enter the IP address manually. To register ip in windows 7 or Windows 8 you need to do the following:
Let's go to Control Panel and click on the icon Network and Sharing Center:
Wait a few minutes before rebooting the router. Most of these channels overlap, but channels 1, 6 and 11 are not and are the most commonly used. If a channel is set to Auto, try setting it to a different channel to see if that improves the connection. Connection cable OK? Before you start thinking about rebooting or replacing your router, check the connection coming into your home. This is usually located on the side of your house and may or may not contain a closet.
Make sure the main cable hasn't been hacked by a squirrel or knocked over by debris from a storm. If a cable splitter is used, make sure each connection is tight and the connectors are properly crimped. If the splitter looks suspicious, try replacing it.
In the window that opens, click on the link Change adapter settings. You will see a list of network adapters. Right-click on the network adapter through which we connect to the router and select the menu item Properties:
Start Fresh If rebooting your router doesn't do the trick, try resetting it to factory defaults and doing a fresh install. Most vendors provide downloadable firmware updates that resolve performance issues, add new features, and improve performance. Locate the firmware update tool in the System section of the router's management console and follow the instructions carefully to make sure you are installing the correct firmware version.
Everyone hates being unplugged. Here are a few reasons why your computer cannot connect to the Internet. There are many reasons why a device will not connect to the network. Some of them are very complex and some of them are simple mistakes. One attempt to check first is the presence of the Internet.
Typically, if you're wirelessly connected to a network without Internet, your computer will show an exclamation mark above the wireless icon to indicate that you can't access the network. Sometimes a web search engine is out of range and only a few feet of movement can fix it.
By this you disable active probing . After that, the system will not check the Windows network connection states for whether the computer is connected to the Internet or to a restricted network.
Many users sooner or later have problems with Wi-Fi connection. The reason for this problem can be both the Wi-Fi router or router itself, and its incorrect configuration (IP addresses are incorrectly configured, the settings at the address, 192.168.0.1, etc. have gone wrong). As a result of this, the Internet seems to be there, for example, when the cable is connected directly to the computer, but Wi-Fi does not work and there is no connection.
Today I will consider a situation that users of Windows 7 and Windows 8 operating systems very often face. The essence of the problem is as follows, there is a network connection, but the Control Center ...
It occurs, as a rule, when you change your home modem or move to a new place of residence. As they often say in such cases, everything seemed to work and nothing changed. Nevertheless, there are some nuances here.
Now we will talk about only one of the most common causes of this problem and only one simple solution. After all, this is how the author has always managed to access the Internet.
So let's start from the beginning. And the first thing we will consider is Wi-Fi. If, when connecting to a modem in this way, you receive the following message in the "Network and Sharing Center":
So, the first step is to do one simple operation. Further, all settings will be shown using the example of Windows 10, but in older systems everything is done by analogy. The main thing is to understand the general essence.
Right-click on "Start" and select "Network Connections":
Then you need to select the wireless network adapter, and right-click on it again. In the menu that opens, select the line "Properties":
In the next step, we follow the path "IP version 4-Properties":
And we check that the option "Obtain an IP address automatically" is activated in all points:
After that, in theory, the annoying message "Unidentified network without access to the Internet" should disappear. So let's check if this is really the case. After all, you can only trust your own eyes.
To do this, click on the wireless connection icon in the system tray and select "Network and Sharing Center":
And here, please, there is no trace of the hateful message:
Now you can safely use the network with the Internet. By the way, the settings of the IP addresses of the network card can also be changed through the "Change adapter settings" item. Remember this point, as we will return to it later.
Okay, but let's now talk about a situation where the situation has not changed after the above settings. In this case, it can be assumed that your home modem simply has the DHCP server function disabled.
After all, it is she who is responsible for the automatic distribution of IP addresses to devices connecting to it. And here it must be said that setting it up for each router model will be individual.
On the example of the article, this case looks like this:
So, ladies and gentlemen, enable this option for yourself and you will be happy. And now let's move on to setting up a wired network card. How to configure it correctly in case of lack of access to the Internet?
The most interesting thing is that in this case, you need to act the other way around. That is, the values of IP addresses must be set manually. This is done in the following way. Select the wired network adapter and go to its properties:
