Network problems: How can we solve the different connection errors in a network?

The networks sometimes give connection problems, which is sometimes due to the Internet operator to which we are affiliated. However, if the ADSL is working well and the telephone wiring of our office or home is fine, There are several factors that must be taken into consideration to make the respective diagnosis..

In Windows there are programs that are essential for it to work correctly, as well as its applications and processes. This being the connectivity of your network, because without it it is impossible to access the Internet and receive the appropriate updates.

There are many issues that cause the network to fail to connect. It may be a physical problem, for example that the drivers do not work. Below we will explain what all of them are and how to solve them easily and effectively.

What tools can we use to identify a network problem?

The software that can help solve any type of problem has instruments that are used to manage the networks of the systems. Likewise, help you browse the tools that are online, knowledge bases and protocols. They also troubleshoot hardware, cable testers, and portable networks.

There are several tools that can be used when a difficulty arises, when applying them they will carry out a study on the network to repair the problem that exists. Some of them are the following:

Command Prompt (CMD) or Terminal

There are operating systems that already have many network tools, such as ping, ipconfig (ifconfig, on Linux), or tracert, which are essential to be able to configure the local network as well as the connectivity. Likewise, these are used to verify the programs that are disabled or present some type of problem in their packages.

speed test

With this test we know what the speed is high and low of the network connection. This helps us to know when there is a problem, indicating if the problem that occurs is due to the connection or because there is not enough speed. Likewise, you can tell us if this has been caused because the web page you want to access has a problem.

Windows troubleshooter

Microsoft has certain tools that have been created to tell us when there is a problem in the operating system, one of these being the network connection.

Usually these tools used to examine each of the packets and thus the traffic that is in our network can be captured. All this with the purpose of being able to know and detect the inconveniences that may arise in the network. However, we also have another similar tool called Microsoft Message Analyzer.

NetCrunchTools

This is a professional tool that helps to have at hand the tools needed to audit and examine the networkas well as essential applications and deeper tools such as DNS and ports.

Network Management System (NMS) Instruments

help to monitor and examine the level in which the equipment is, in order to manage and show the faults that exist. With them it is easy to identify a failure accurately, but handling them requires some technical knowledge.

List of the main network errors and how to solve them to reconnect

Sometimes networks throw errors, For this reason, if you want our device to work correctly, we indicate below how to solve it:

IP Address Problems

Sometimes two devices have the same IP, and one of them can be static. This is called duplicate IP.

So that this does not happen what must be done is maintain an orderly network, to avoid any type of inconvenience and thus be able to verify any failure that may occur. Also, note that there are not two DHCP servers running.

Difficulties in switches or routers

Network failures in themselves sometimes have no reason, that is, sometimes you are browsing the Internet when suddenly you lose access to it, but in a matter of seconds you have a connection again. This can be solved with just reboot the router or switch.

When this type of inconvenience occurs, it is often necessary to check the power source of the equipment, since the variation of electricity can cause this equipment to be damaged. Once all of the above is verified, you can try another “router or switch”motivated by the fact that if the one you have is damaged, the difficulty will not be corrected.

Connect equipment haphazardly

Being in a hurry sometimes causes the “switches” to be connected in an improper way. When this happens data travels much further, which can cause problems. A suitable solution for this is to organize the networks accordingly in order to avoid any type of error.

NetBIOS problems

This is a Windows protocol, which makes computers on a network talk. However, it is slow on the network and errors are generated when you want to enter the shared files. One solution is to determine which equipment is failing. and rename one by one. Disabling the WINS/NetBT name resolution service may resolve the issue.

Faulty network cards

This is a difficulty that is constantly generated, which is why when a device throws an error constantly or occasionally, it should be check card performancewhere the error can be distinguished by observing the white or green LED that each one has.

This must be kept on, it must also be verified that the wiring is connected correctly and verify that it is in good condition.

Lack of Bandwidth

The bandwidth in opportunities does not satisfy the demands of the network, for which it is recommended that a good investment be made when laying the cables. In addition, the bandwidth in the local network can be affected by the type of router or switches that you have.

DNS errors

Although these errors can be due to multiple factors, to simplify the causes it is advisable to start with keep computers free of viruses or malware and make sure the Modem or Router is working properly. DNS help solve problems when searching for something on the Internet, so they should always be kept up to date.
