Modem without Internet access what to do. Wi-Fi network without internet access. We solve the problem using the example of a TP-Link router. Let's fix the situation

The first setup of the MTS 4g modem is both a simple and skill-requiring thing. Such a unit is designed so that you can go online where you need it and when there is no access to wired Internet or does not catch Wi-Fi. The coverage of the MTS 4 g network covers a large area, so there should be no communication problems. It is a small block that is inserted into the USB connector like a flash drive. Agree that it is very convenient to have it on hand? The device does not take up much space and fits easily into a laptop bag or just in your pocket.

To get started, it is enough to perform a small setup that can activate the 4g MTS modem. The interface of most programs is designed in such a way that it is not necessary to have special knowledge in the field of computer science and programming. During installation, the program does everything autonomously, you only need to agree with the actions performed and specify the path to save the files.

Let's take a closer look at how to properly install a 4 g MTS modem on a computer. It is worth noting that the basic kit includes the device itself, instructions for it and a SIM card. To broaden your horizons and compare, you can still read about.

How to connect 4g modem MTS to a computer

Initially, you should, as you already guessed, insert a SIM card into a special slot. The device will work in the LTE network only with the SIM card that comes with it. If you install another SIM card, it will work on the 3g network and the speed, accordingly, will be lower than stated. Here you can find out, maybe it will be more relevant for you.

How to set up a 4g modem MTS

After preparing for work, you need to insert the device into a computer or laptop. The operating system will automatically detect and recognize new hardware, and then activate the installation wizard itself. If this does not happen, then you need to go to the "Start" menu, then go to the "Computer" section. The USB modem will show up as a removable disk because it is configured with a Micro SD card slot. Installing a memory card just allows us to use it as a removable disk.

Open the drive and double click on the Autorun.exe file,

Then follow the prompts that will pop up on the screen from the installation wizard.

Launch program shortcut "Connect manager", which will be displayed after installation on the desktop.
When the modem registers on the Internet, click on the "Connect" button.

First, in the device selection section, the message “MTS connection is not connected to the network” will appear. Do not worry, but wait for the connection. Immediately after establishing an Internet connection, the message “MTS connection is connected to the network” will pop up in the device selection menu.
In the "Connect" section, click the "Disconnect" button to suspend the connection to the Internet.

Additionally, in the Connect Manager application, you can also send SMS, activate a payment card, check the current balance and the balance of the megabyte package.

MTS settings for 4g usb modem with wifi router function

All Wi-Fi equipment in the house, be it a smartphone, TV, tablet, refrigerator, and much more, can be connected to the World Wide Web using a flagship with a wifi router function. You can connect such a 4g MTS modem to a power adapter or PC and put into operation no more than 10 devices at the same time.

The installation process will depend on the computer's operating system. Let's look at an example installation for Windows XP:

Insert the device into the USB port;
Follow the steps that the installation wizard asks;
If you encounter difficulties with automatic configuration, manually run the AutoRun.exe file;

Open the address of the router settings in the browser (they are on the device itself). Next, enter the standard username and password - admin;

Check your access point settings- the checkbox is not used by default should be unchecked;
Make sure that other devices do not work on the distribution of the signal, this may lead to a failure in the operation of all modules.
If you still cannot access the Internet, then try restarting your computer.

You can see it in a separate article.

The Internet is an integral part of our life - it is an excellent assistant in work, an indispensable tool in learning, moreover, it is a means of communication and recreation. Users everywhere face connection problems. Consider in this article the most common error - IPv4 without access to the Internet and how to fix it? If Windows gave you this alert, then you should go through all the options by the elimination method in order to find out what caused it.

Ipv4 is the Internet Protocol, I don't think it needs translation, and the version of the protocol is the fourth. You probably paid attention to the presence of the IPv6 protocol in the settings - this is also the Internet protocol, but already the sixth version, only single providers use it. The most common and mainstream today is IPv4. The main task of the IPv4 protocol is to ensure the functioning of the computer and networks according to the established rules for the exchange of data packets. So, the interaction takes place between the communication node and the IP address of the machine, IPv4 is a low-level protocol.

If the terminology causes difficulties for you, then we additionally recommend that you read our other article,

In order to accurately and as quickly as possible fix the access problem, we will consider the cause and method of its elimination.

Reboot: reboot will help fix the error

It is not for nothing that the well-known proverb in the circles of IT specialists has taken a new form and sounds like: “Seven troubles - one reset”. In our case, reset is the last resort to fix the error. Terms:

reset - or rollback to the last successful version;
reboot - reboot, in other words, complete unloading and loading of the operating system;
restart - restart.

Let's start correcting the situation.

Restart your computer (don't turn it off and on!). Sometimes this is a fairly effective method to fix the problem.
99% of users use routers and routers, since there are more than one devices with Internet access in the house - restart the router / router.
Try to suspend or completely disable the antivirus, for various reasons, blocking occurs due to it. If everything works, reinstall the antivirus and you may need to update the program module.
Analyze what changes were made to the system before the IPv4 error occurred without network access. Try to roll back the installation / configuration of the program / utility, etc., if this corrected the situation, then the reason is precisely in the changes made earlier.

Little experience...

Did the above steps not fix it? Going further, we need to exclude the variant of the problem on the provider's side, namely, to check if the Internet works on other devices.

Check another device for network access. If everything works on that device, and there is no IPv4 error without network access, then the cause is in the computer. This can be either a software error or a physical malfunction. We will consider a software error in more detail later, and a physical one can be from a detached network cable (patchcort) to a network card failure.
If the machine is connected directly without the participation of a router, and an IPv4 error occurs without network access, try connecting another computer / laptop instead. Again, depending on whether it works or not, we check the physical state and then move on to software solutions.
If the network does not work on any of the devices connected by any of the methods, call your provider's technical support for clarification and do not forget to announce that Windows displays the message "IPv4 without access to the Internet." They should help fix it.
Probably, it will sound trite and even a little funny, but if our smaller brothers live at home - check the integrity of the cables, damage is possible, which was the above error - IPv4 without network access.

Get to the root...

After eliminating a number of simple reasons to fix the problem, let's move on to the most important ones. The world wide web does not work, and the operating system gives an error: IPv4 without access to the Internet. So, let's start in order.

Internet settings: provider and router

Of course, the easiest thing is to call the provider and clarify everything with him, after saying about the error - IPv4 without access to the Internet. Perhaps an expert will advise how to fix it. First, you need to look into the settings of your router and check whether the data is entered correctly. Let's see what the IPv4 error looks like without Internet access. Regardless of whether the connection was made via Wi-Fi or using a network cable, a yellow exclamation mark will appear.

I would like to make a reservation that the fix for the problem with the IPv4 name without access to the network is the same for various connections and versions of Windows from 7 to 10. To fix, you must first find out the cause of the IPv4 error without access to the Internet.
We go to the "Network and Sharing Center" - using any of the 2 methods:

1 way

 right-click (hereinafter RMB) click on the connection sign with a yellow exclamation mark → select "Network and Sharing Center" → note that "Access type" says "Without access to the Internet" → select "Change adapter settings" → find your connection;

2 way

Once in the correct directory:

"Windows Network Diagnostics" will start - wait for completion and as a result - problems are detected, as well as tips on how to fix them.
diagnostics determined that - this is the main cause of the IPv4 error without access to the Internet;
to fix it, go to the window "Status - Ethernet" or "Status - Wireless network connection" - in the above way;
select "Properties" → select "Internet Protocol Version 4 (TCP / IPv4)" → "Properties".

In the window that opens, you must specify the type of IP address and DNS. We will describe all possible options on how to fix the IPv4 problem without access to the Internet.

Static IP and DNS

Is the home network set up so that each device has its own and is accessed using DNS? To accurately specify the settings and fix the IPv4 error without access to the Internet, go to your router, we show the Asus router as an example.

the address of the settings page is available at the address “192.168.1.1” - enter without quotes in the address bar of the browser → → authentication is required, as a rule, the login and password are “Admin”, the entrance can also be without specifying a password;
go to the “LAN” section → “LAN IP address” → the specified IP address is the main gateway;
then we go to the section "DHCP - server" - here the initial and final pool of addresses are indicated, as well as a list of those already assigned by the MAC address of the device. The MAC address is the unique serial number of the network card. Find the desired device and remember/write it down.
Dynamic IP - address
It happens that everything is configured correctly, but a DNS server error occurs and the system displays a message - IPv4 without network access. This is due to an overload or error in the operation of DNS servers on the provider's side. And in the router you can see that the Internet reaches you. In this case, alternative DNS from Google, which are public, come to the rescue to remedy the situation. So:

With such a simple method, you can fix the IPv4 connection error that occurs.

Stable connection!

If some providers do not support the ipv6 protocol, and the protocol is not used in conjunction with the router, then ipv4 is directly responsible for the availability of the Internet. Therefore, in the article we will look at ways to troubleshoot when the error “ipv4 without access to the Internet” appears.

Why does ipv4 error occur without internet access

When using the Internet by a user, the chain consists of three segments - provider, network and user equipment. Failures or problems in one of the listed segments, and lead to the absence of the Internet. And troubleshooting a router or computer will not fix the problem if the provider has problems. Therefore, to save time and effort, it is important to understand and identify the problematic segment.

The best way to determine is to exclude the superfluous:

Call the operator and make sure the correct provision of services at your address.
If you are using a router, check the operation of the local and wireless networks by connecting other devices. In the absence of restrictions on the part of the provider and operability with other devices, the problem should be sought in the main computer.
Connect the internet cable to the network card of the main computer. In the absence of restrictions on the part of the provider and the performance of the Internet, the problem should be sought in the router.

Another way is diagnostics by means of the OS.

If the error occurred due to the fault of the provider

Contact your ISP and find out why there is no connection. In the event of an accident or scheduled maintenance / replacement of equipment, the provider is obliged to communicate the deadline for completion of repairs. If the network cable is damaged, request a replacement service call.

In apartment buildings, the provider's equipment is located mainly on the roof. In the event of a power outage or power failure, the equipment shuts down. After power on, it usually takes 5-10 minutes to turn on. Sometimes a restart of the computer/network equipment is required to resume operation. Also, failures in the supply of the Internet can be observed during thunderstorms.

If the error is due to the router

Before proceeding to find and eliminate probable causes, make sure that the network equipment is connected correctly. When connecting wires, it is important not to confuse the LAN and WAN ports. Sometimes the network cable is loose in the WAN connector. Therefore, it is important to check the tightness of the connection.

Solution 1: Check connection settings

Open the router control panel and go to the network settings. Make sure that the WAN connection type is set correctly and the parameters are set in accordance with the requirements of the provider.

Also open the DHCP settings. The server must be enabled. The start IP address is 192.168.1.100, the end IP address is 192.168.1.199.

Solution 2: Factory reset/change firmware

Sometimes the router refuses to save the entered settings. In this case, a reset and reconfiguration helps. Sometimes it is necessary to replace the firmware, in rare cases, the replacement of the router itself.

If an error occurs on the computer

Solution 1: check the connection settings / manually enter the gateway address

Open network connections, where select the properties of your Internet connection.
Select ipv4 protocol and then open properties.
Make sure the settings are set correctly. If you are connected via a router, use automatic retrieval of parameters.

Sometimes the DHCP server does not pass the gateway address. In this case, you need to register the gateway manually. The required data will be provided to you by the provider when contacting.

Also try to specify the automatic receipt of the IP address. In the DNS server values, specify:

Preferred - 8.8.8.8.

Alternative - 8.8.4.4.

Solution 2: Disable or change firewall settings

If the message "ipv4 without access to the Internet" appeared after installing an antivirus or firewall, or tampering with the settings, then disable the programs for a while.

Sometimes you need to disable the built-in Windows Firewall. To do this, open the control panel, then "system and security". In the new window "Windows Firewall", and after "Turn Windows Firewall on or off".

Solution 3: Disable Power Saving Features

Active power saving modes contribute to temporary or permanent Internet shutdown. Therefore, it is required to double-check and disable the corresponding functions.

Power Mode

Open Power Options as shown in the images below.

Select balanced or high performance mode.

If changes have been made to the plan, return the settings to their original state.

Additional network card options

In Control Panel, select System and Security.

Under System, select Device Manager.

Find "network adapters" in the list.

Open the properties of the network card.

Under the Advanced tab, look for green and power-saving features. In the value of each item, select "disable".

Conclusion

If an ipv4 error appears without access to the Internet, make sure that the problems are not on the provider's side. Turn off the router to rule out problems with network equipment. If the problem is related to the computer, manually set the IP address and DNS server settings, or use automatic or semi-automatic settings, for example, only specifying the server address. Also, turn off power saving features to prevent internet outage.

This problem exists and many users have been affected by it. Its essence is as follows: a Wi-Fi router is purchased, it is connected and configured, but the Internet is still missing and the Internet is not distributed to remote devices. A network without Internet access is a situation that has a variety of causes:

The router may be faulty, which is quite rare, but still happens.
The router may not be configured correctly.
WAN usage may be limited by your ISP. For example, if you are late in paying for services.
The problem may be in the computer or laptop.

And some others. A network without Internet access can be tested on different devices. In the event that the Internet is not available when connecting different subscribers to the router, this means that the problem should be looked for in the router or find out if the network is limited by the provider.

The latter is especially easy to do - you just need to call the operator by phone. But most often, a network without access to the Internet is due to incorrectly configured router settings. Further we will consider just such a situation.

What does the picture look like in practice?

Below is a picture showing a typical grid pattern without Internet access:

All this does not depend on the router model at all, but is only a consequence of incorrectly made settings. To begin with, such settings must be “reset” - that is, transfer the router to the state in which it was immediately after exiting the assembly line. Each such device has a button labeled "Reset". It can be located either on the side of the instrument case or on its rear wall.

As a rule, the button has a small size. This is done to prevent it from being accidentally pressed. Another protective measure is the need to keep the button pressed for some time (usually about 10 seconds). That's the only way to make it work. So, take an object with a sharp tip and press the button with it, holding it for a while. The signal that the settings have been reset will be multiple flashing of the front panel lights.

For beginners, the following figure may be helpful:

It shows the correct connection of the cables of the provider, the connecting cable and the power supply cord. Check if the connection of your router matches what is shown in this picture.

Is the connection type correct?

Among the software settings of the router, there is one parameter that is critical for the normal functioning of Wi-Fi. This is the type of Internet connection. If you specify the wrong type of connection, access to the Internet becomes impossible. If, when the router is physically connected to the computer, when setting up the router, Windows writes “without access to the Internet” - first of all, check the type of connection. this parameter can take the following values:

PPPoE.
L2TP.
PPTP.
Static IP.
Dynamic IP.

Each connection type has its own settings. You should find out from the provider what kind of connections he uses to connect subscribers. The most elementary is the connection to the network using a dynamically assigned address.

In this case, you do not need to specify any additional parameters, such as IP address, gateway addresses, etc. PPTP, PPPoE and L2TP usually require you to specify a login and password assigned to you by your ISP. These data are usually specified in the connection agreement. A static IP will require you to specify the IP address itself, the gateway address, and DNS addresses in the router settings. They must match those of the computer connected to the device. It is not difficult to find out all these parameters by typing the command in the Windows console: ipconfig /all.

Binding by MAC address

This is the usual technology for identifying users by the provider. Each network device is assigned a unique identifier - the so-called MAC address. When connecting, the provider can control this parameter and, if it does not correspond to the one stated in the contract and the provider's internal database, reset such a connection. Many have encountered this situation when reconnecting the provider's cable to another computer or laptop. In this situation, you have to manually enter the MAC address in the Internet connection settings.

Approximately the same thing has to be done when connecting to the router's network. To do this, its settings have a special interface, usually equipped with a button labeled like “Clone MAC Address” (“Clone MAC Address”) or something like that. If you correctly specified the type and parameters of the network connection, but you still can’t connect to the Internet, try cloning the MAC address. Or call the provider with a request for advice on this matter. You may also find detailed information on the website of your ISP.

How to find out the value of the MAC address of your computer? Using the above command: ipconfig /all. The list of its output contains such information.
