Programs to troubleshoot network connection problems. Guide to Troubleshooting Internet Connection Problems

Read guide to troubleshoot various network connection problems in Windows. Five universal ways. You may also want to check out our earlier article, A Guide to Troubleshooting Internet Connection Problems, in which we tried to cover a different range of Internet connection problems.

The essence of the problem

The concept of the Internet today has become very firmly entrenched in our lives, and most people use it fully and everywhere. On the Internet, people are trained and gain knowledge; visit exhibitions and libraries; communicate through social networks and video communicators ( "Skype", "Viber" etc.); develop projects; transmit and receive information, letters and documents; learn and share news; watch movies and listen to music and much more. It is not surprising that the ability to access the Internet is supported by many various devices: personal computers, laptops, smartphones, tablets. All of them provide connection to the Internet in different ways: using a cable, via « Wi-Fi connections» or taking advantage of opportunities mobile access through the services of mobile operators.

Sometimes devices are combined different ways connection to the Internet, for example, a laptop can be connected directly with a cable and using "Wi-Fi connections", the smartphone has "Wi-Fi" connection and Mobile Internet. But sometimes there are various connection problems such as no connection, limited connection, inability to access network drives or browsing websites, etc. In this case, you encounter problems connecting to the Internet or local network V "Windows". Or you receive error notifications containing such error codes. It happens that the connection does not work "Ethernet" or function "Wi-Fi" your laptop, or there was a problem with the connection settings. This situation is very upsetting and you try to find a way out of the situation on your own.

In this article, we will try to tell you about various problems when connecting to the Internet and how to solve them for different types network and Internet connections in the operating system "Windows". Most of the methods given in this article will work in all versions "Windows", but some of them will only be available for certain operating systems.

We will try to list the main possible solutions to fix network and internet connection related problems in "Windows". You should try these solutions one by one. And one of them may be able to help you troubleshoot problems.

METHOD 1: Run the built-in network troubleshooter

The first thing you should try to fix problems with network connection is to activate the built-in troubleshooting tool and network problems V "Windows". This tool automatically diagnoses and finds the cause of the problem, and tries to fix the problem if possible.

To run the troubleshooter, click right click mouse icon "Net" located in the notification area on "Taskbars" and select section from the pop-up menu.

The problem detection process will start, the result of which you will see in the window.

Wait a few seconds, during which time the tool will diagnose networks, perform troubleshooting, check Internet connectivity, find the cause of the problem and show ways to fix it.

In most cases, this built-in problem detection tool will completely fix the problem and restore your Internet connection. IN as a last resort, he will point out to you the existing malfunction and suggest a solution to it.

METHOD 2: Use the function "Network reset"(Windows 10 only)

Sometimes the built-in troubleshooter (described in Method 1) cannot resolve connection issues. Then you need to manually reset your network connection settings and network adapters.

And if you are using an operating system "Windows 10", you can use the built-in function "Network reset" to automatically reset network adapters and network components. This feature first removes all installed network adapters and then reinstalls them. It also sets other network components to their original settings.

Function "Network reset" was added to "Windows 10" to the update version "Windows 10 Anniversary Update"(version 1607). This feature was designed to help users resolve connection issues after updating operating system To "Windows 10" from previous version "Windows". It can also do a great job of helping users troubleshoot network connection issues they may encounter later in their future use.

To access the function "Network reset", you just need to follow these steps:

METHOD 3: Assign IP address and DNS manually

After update previous versions "Windows" to the latest operating system "Windows 10", you may have a problem accessing the Internet. Sometimes this may be due to problems with your Internet service provider, and you need to wait a few minutes, or contact the provider's support team. However, if access to the Internet does not resume, then you need to check whether all necessary protocols are enabled in the connection properties. Open a window, this can be achieved in several ways:

Method 1: Right click on the icon "Net", which is located in the notification area on "Taskbars", and select the section from the pop-up menu.

Or press the keyboard shortcut together "Windows + X" and select section.

In the window that opens, in the right pane, move the slider down and click the link.

Method 2: The simplest and most quick way, press the keyboard shortcut together "Windows + R", in the window "Run" enter in the field command line "ncpa.cpl".

A list of connections will open in the window. Right-click on the connection you use to access the Internet and select "Properties".

Pay attention to the section "The marked components are used by this connection". The connection protocol cell should be checked in it "IP version 4 (TCP/IPv4)". Otherwise, you need to enable it by checking the box in the cell. If your protocols are enabled, but Internet access does not appear, then try setting up this protocol manually. Click the button "Properties" and go to the next settings window.

Check the box "Use the following IP address" and fill in the fields "IP addresses" And "DNS servers". You can find out the input parameters by contacting your Internet service provider's support team. Click the button "OK" to save your changes.

The problem with Internet access should now disappear.

METHOD 4: Using Registry Settings

This method is suitable for "Windows 7, 8, 8.1" and only if none of the connection types are displayed in the folder. Remember that the procedure for editing the registry requires you to be careful and accurate. Otherwise, you may make erroneous changes and disrupt the correct operation of the operating system as a whole or its individual applications. Be sure to save its original settings before editing the registry. In the main menu ribbon, click on the tab "File" and select the section in the menu that opens "Export". Name the registry file, select the path to store it and click the button "Save". Now you can always use the saved version of the registry if the need arises.

Chief, everything is gone, everything is gone! ...Calm down, Kozlodoev! Let's all sit down! (c) Diamond hand

First of all, read all 8 methods carefully. It is absolutely not necessary to do them in this order!

1. Check the integrity of the cable connection

You can perform any manipulations to set up a network connection, but if your connector falls out of the connector or is torn network cable, then the result of all your efforts will be zero.

Start by visually checking the cables or telephone wires that connect your computer, modem, or stand-alone router to the Internet. Even if the router in your apartment is wireless, it is still connected to the external network using a cable!

Start moving from the computer, modem or router to the point where the cable enters the yard, house or apartment. Make sure that all connectors are securely connected and that the cable and wires are not physically damaged.

At the same time, check the power supply of modems or routers! If any of these network devices de-energized, broken or simply turned off - take appropriate measures.

2. Reboot your modem or router

Sometimes a modem, which outwardly appears to be fully functional, loses connection with the network and, as they say, “freezes.” To resume the connection, it needs to re-register on the network. Simply turn off the modem's power, wait a few seconds, and turn it on again. Wait until the modem boot process completes. If, in addition to the modem, there is also a separate router on your local network, reboot it in the same way.

3. If you have satellite Internet

If you are using satellite dish to connect to the Internet, make sure that it is not covered with ice in winter, is not covered with fallen leaves in autumn, and tall trees with dense summer foliage do not grow opposite it. Also pay attention to ensure that the antenna does not change its orientation, for example, after hurricane wind gusts or repair work on the roof.

4.If you have Wi-Fi

If you are using wireless point access or wireless router to access the Internet, then the wireless connection may be the cause of your problem. You may need to use a wired network connection until wireless problem will not be resolved. Therefore, it is advisable to have a small network cable for direct connection your computer to your modem or wireless router.

There are two main potential problems with wireless connections: a configuration problem and a security problem. Refer to your user manual to see how to access your wireless device via network cable. This is done by entering the IP address of this device into the web browser, then you need to enter the username and password to enter the control panel of this router. If, as usual, there is no manual at hand, then the standard ones:

Router control panel IP address 192.168.1.1

Login admin, password admin or no password at all

Login root, password root or no password at all

Don't forget to set it in your settings network card IP address 192.168.1.2 How to do this is described in paragraph 7.

From the router's control panel, check that the settings are correct. You may need to call your Internet Service Provider (ISP) for assistance if your current configuration is very different from the settings provided by your ISP. The provider's operator will provide you with the necessary information for this network connection over the phone.

Wireless device security may also be a problem. You can also configure these settings from the router control panel. If you have wireless security enabled, you will not be able to access your wireless device without using correct password. You will be able to reset your password and set a new one if necessary.

Read, how to fix internet connection problems at home. A few mandatory steps before contacting a specialist or provider. Internet connection problems are very frustrating for us. Instead of pointlessly poking F5 and desperately trying to reload your favorite website, we suggest trying a few troubleshooting methods to determine why your connection is failing.

Ping command

The first thing to do when you have connection problems is to run the command "ping". Launch the Windows command line (how to run the Windows command line as an administrator, watch the video on our channel on how to launch the Windows command line) and enter, for example, or "ping site".

This command will send several packets to the address you specify, and the web server will respond to each of them. In the screenshot below, we will see that everything is working fine. Packet loss is 0%, and the time spent by each packet traveling along the route is minimal.

If you notice packet loss (in other words, if the web server did not respond to one or more requests sent), then this clearly indicates problems with the network. If the web server response time for different packages varies greatly, this indicates a high load on the Internet channel. The problem could also be related to the website itself (unlikely if the same problem occurs on several web resources), to your Internet service provider, or to your local network (for example, with your router).

Please note that some web servers cannot exchange packets. For example, the command "ping microsoft.com" will result in 100% packet loss.

Problems encountered with a specific website

If access problems occur only for a certain website, and it shows that everything is in order, then, most likely, the problems arose on the server where the website is physically located.

To check if this site is working properly, we can use a special tool on the web - www.downforeveryoneorjustme.com. It allows you to poll websites from different IP addresses and determine whether they are actually working or not. If you receive an answer that the site does not work for everyone, then the problem is definitely on the server.

The site’s response that this web resource does not work only for you indicates connection errors on your part. And there can be at least a dozen options. There may be a discrepancy in the routing between your computer and the server on the Internet. To identify such problems, you must use the command "tracert", for example, enter "tracert google.com" on the Windows command line. The utility will send a trace packet and display the IP addresses and names of all nodes with which the packet interacts as it follows the route. If the error is detected after your Internet provider's server, then you basically can't do anything other than wait for it to be fixed.

Problems with the modem or router (router)

The inability to access various websites may be caused by your modem or router.

Many people use a modem to connect to the Internet, that is, physical device, which transmits digital data via analog channels. The modem converts the analog signal into a digital one, and vice versa. For such interaction, it has two interfaces, digital for the computer and analog for telephone line. A modem is a device that communicates with your Internet service provider.

A router is also a physical device that, via wired, wireless or mobile network connects to the Internet. In addition, it can connect all devices that are equipped with Ethernet network ports and Wi-Fi adapters, into one local network. With its help, local network participants can freely exchange files and remotely control other devices (for example: printers, TVs, etc.).

In some cases, the modem and router may be the same device.

Take a look at the router. If it has blue or green lights flashing ( different manufacturers may use different colors), then this is normal and indicates a stable Internet connection and local network connection. But if you see a steady blinking orange (or red) indicator light, this usually indicates the absence of them. The same applies to the modem - a flashing orange light usually indicates a problem.

If the lights indicate that there is a problem on both devices, try turning them off and on again. That is, restart the devices, just like restarting your computer. You can perform this step even if the lights are blinking normally - there are some routers that sometimes need to be rebooted for them to work properly. After a few minutes, your modem or router should reconnect to your ISP. The error may be related to updating the servers of the provider itself.

If this does not solve the problem, then you can reset your router or update the firmware. To check if the problem is actually with your router, you can connect your computer's Ethernet cable directly to the modem, bypassing the router. If the connection is restored, then it is clear which device is causing the problem.

Possible problems on your computer

If you're having network problems on just one computer on your local network, it's most likely a software issue. It may be caused by a virus, some malware or a browser error.

Run a scan of your system with antivirus software and try installing a different browser, then try opening this site in new program. Other errors may also occur, such as an incorrect firewall configuration.

Problems with DNS servers

When you load a Google.com resource, your computer contacts its DNS server and requests the web resource's IP address. The default DNS servers used by your network are provided by your ISP, and if they have not been updated, problems may arise.

You can try to access a website by IP address directly, bypassing the DNS server. For example, copy the address "http://216.58.197.78" into your web browser's address bar to visit Google.com directly.

If you were able to log in via an IP address, but still cannot open the site by simply entering Google.com in the address bar, then this is a problem with the DNS servers. Instead of waiting for your ISP to update their server, you can try using a third-party DNS server such as OpenDNS or Google Public DNS.

Ultimately, most connection problems you encounter are someone else's glitches or mistakes—you can't fix them yourself. Often, the only thing you can do is wait for your ISP or specific website to fix the problem.

And of course, you can always call your ISP's customer support by phone. Support can check the connection to your computer (router or modem) to determine if there are any problems. They will tell you whether there is a server error or whether the problem is on your part. Also see what you can do to speed up your Internet connection.

To troubleshoot network problems, it is important to have a basic understanding of network setup. There are three categories of network problems: physical problem, configuration problem, and software problem. The first step to take when you set out to troubleshoot network problems is to determine what type of problem you have. This solution is the first of many that will help you solve the problem. There are two simple rules that are critical if you want to successfully troubleshoot network problems. The first rule is to change only one thing at a time and then test it. A logical, methodical approach is the only one effective method fixing technology problems.
There are often multiple causes of network problems. If you can't identify an action and associated outcome, you have no idea whether you're on the right track or not. A number of changes can also lead to unexpected results. One step after another is the best way to continue searching for network problems.

Finding problems downward is the second rule for troubleshooting. Make clear notes on the form that explain the steps you took and the result you obtained. These notes are invaluable and will help you build a knowledge base that you can rely on when you're trying to troubleshoot problems.

Whenever network problems occur, always start with the physical network. Check devices, connections and power. Don't make any assumptions and check each connector carefully. These problems are the easiest to fix and are the most common. Follow the cable to make sure everything is connected correctly.

If the problem is not hardware, look at the configuration. The first step is to create a system restore point in the software configuration. This will allow you to start from the same point if necessary. Look at your notes from the installation and don't forget to take new notes.

To begin troubleshooting, you must check the configuration of each computer on the network. This information can be accessed by entering "ipconfig" at the command prompt for each computer. To obtain full level details, enter “ipconfig /all”. Review the information and compare it with initial setting. Errors or inconsistencies will cause most problems.

The most common software problems are related to the firewall installation. Check your antivirus software, as it is often associated with a firewall. Installing multiple firewalls will create a cascading series of network problems. Look for any settings that may have changed.

find out , How to Troubleshoot connection problems To Internet

Have you been unable to connect to the Internet? Well let's take a look at possible reasons and show you how to eliminate them.

To make things easier, we will follow a 3 step process to resolve the issue you are facing.

Step 1: Modem and ISP (your ISP)

We have to start right from the source, you connecting to your ISP.

1. Contact your ISP and check if your internet service is activated, if so, are they experiencing downtime/line cuts or other problems? If they are having problems, you won't be alone, and they will probably work overtime to fix it, and you'll be hooked right away!

2. The connection is good, what next? Well, whatever modem/router you are using with your connection. Make sure the cables; data and power are connected correctly. Also, check with your modem/router's instruction manual if you have configured your connections. If you bought the modem separately, you will most likely have to configure it as opposed to the pre-configured one supplied by your ISP. So, once your done checking the status of your modem/router, you should be able to see the modem's transmit/receive lights blinking away connections!

Step 2: Configure Internet Settings

This step involves configuring your operating system's Internet settings to detect Internet connections successfully and share them with applications that need them.

1. Check the details regarding the following information provided to your Internet Service Provider (ISP) for your Internet Protocol (IP):

– IP address

- Subnet mask

– Default gateway

– DNS servers

After receiving the above details from your ISP, you need to view the current IP details on your computer by following these steps:

– Go to: Start>Run>CMD>Type IPCONFIG/ALL into the command line window. (Note, What V Windows Vista and 7 you need to search for ‘Run’ in the search bar in the Start menu)

– By doing this, you will see the current details for the four above requirements. You will need to share these details with your provider to help fix this problem. Please note that, non-conforming parts on at this stage may be caused by a defective hardware component or due to incorrect modem configuration.

2. Checking whether the Internet protocol suite (otherwise known as TCP / IP) is configured correctly by performing a PING test.

– Go to: Start > Run > CMD > and type ‘ ping (router address) ‘

In most cases the address will be “192.168.1.1”. You can also PING an external address for further verification.

You should see several hours of responses follow the ping statistics, indicating that all is well.

3. You can also use Windows tool Network Diagnostics to collect information about your Internet/network connections.

Start > Help and Support > Type Network Diagnostics and it should give you the ability to run network diagnostics.

Trying to restore your network connection may or may not help, depending on the type of task. Here's how you do it:

Start > Settings > Network Connections > Select your network adapter> Right-click and select Restore.

Once the process is completed, it should tell you if the repair was successful or not.

Step 3: Browser/Application Setup

Once you've gone through Step 1 & Step 2, it's safe to say that your Internet connection is completely normal. The problem is the application is trying to use it, in most cases your browser, Internet Explorer, For example.

– Open Internet Explorer and get to the options:

Internet Explorer > Tools > Properties Browser > Connections > LAN Settings > Uncheck Automatic detection parameters And Use proxy – server for your options LAN> OK> Apply and OK.

Now trying to open a web page should bring a smile to your face.

– Similar settings available in other browsers must also be disabled for them in order to successfully use the Internet connection.

So here you go, all geared towards an enriching Internet experience and nothing will stop you now.
