In this video, let's figure out how to check speeds local network. As a rule, the need to check the data transfer rate in the network appears when there is a malfunction, or rather, at a low speed. So, within the framework of this lesson, we will consider the work of the program for checking the speed of the local LAN networks Speed Test, as well as consider a case study to understand how to accurately identify the cause of low speed or network failure.
Let's say I need to measure the speed of data transfer in the local network between the server and workstation. The simplest option is to copy some file and see the approximate speed of the local network in the copy information window. But, for this, the computer must be open general access for writing, the file to be copied must be big size, in order to have time to analyze the information, and it is also not very convenient to perform a local network speed test between several computers.
Therefore, I will use the LAN Speed Test program, which will greatly simplify the process of measuring the speed of a local network. More fresh version The program has become paid, so I use an outdated, but still free one, especially since its functions are quite enough for me.
The essence of the program is as follows. We specify the path to a folder on the local network, specify the size of the copied file and measure the speed of its writing and reading.
Since I have virtual network, then the measurements do not correspond to reality, since, in fact, the information was not transmitted via physical environment. However, in real network everything will be adequate.
By the way, if you do not have a public folder on your computer with which you need to check the speed of the local network, then hidden network resources that are intended for administrators and are created by default on any computer will help you here.
Looks this resource\\windows-7\C$. Pointing out given way, you can also check the speed of the local network, but for this you need to have administrator rights to this computer, because only the administrator is allowed to connect to the hidden resource. And if you are testing from under account domain administrator, then there will be no problems at all, since doors are open everywhere for you.
You can download the LAN Speed Test program from the link below!
Now consider the situation in which this program Helped me to identify the cause of network failure. In general, there is a remote employee who connects via RDP to one of the workstations in the organization. So he says that the remote desktop is very slow and periodically throws out.
The structure is as follows, there are two switches in different buildings. One contains a server with client computers, and the other contains only workstations. The employee works for client computer No3, so data is transmitted along the following path Server - Switch 1 - Switch 2 - Client 3. And there can be many sources of problems along this path, and in this example there are 11 of them, not counting software errors.
So these can be problems with network cards, a network cable, ports on switches, and a malfunction of the switches themselves. And we need to find out exactly what is the reason, so we will sequentially check each node.
In my situation, it turned out that 2 ports on the second switch were faulty at once. Moreover, other ports either gave out a normal speed, or a low one. As a result, I connected devices to stable working ports, but in any case, I need to buy a new switch, as it is clearly ending its life.
Also, the problem may be in a computer that is actively distributing or downloading via torrent.

Spreading: shareware NetInfo - set of 15 network utilities, combined in a single interface. Among them are Ping and Trace, which are complete analogues of Windows system utilities, but more convenient to use due to the comfortable launch of the corresponding processes. Other utilities include Whois (displays information about a domain or IP address from WHOIS databases), Lookup (looks up a domain name by IP address and vice versa) and Finger (displays information about users connected to a specific server). As well as utilities Daytime (shows the local time of day for the specified remote host), Time (synchronizes system time on a computer with remote server, which provides information about the exact time), Services (checks the availability of network services), E-mail (checks email addresses for existence), etc. There is no Russian-language localization of the program, and the demo version of the program is operational for 30 days and is almost fully functional (tools on the "Web Center" tab do not work). Price commercial version depends on license type - Home users are eligible for a $39.99 Home license. The NetInfo window consists of 15 tabs, each for a different utility, but they can be activated in other ways by selecting the appropriate command from the Tools menu.
To check if the server of interest is "alive", just go to the "Ping" tab, enter the URL in the "Host" field and click on the "Start" button. The report will display the same information that can be seen in the command window after running system utility Ping - that is, all sent by specified address requests, as well as the values of the RTT and TTL parameters.
Starting a trace is no different - you need to open the "Trace" tab, enter the URL in the "Host" field and click on the "Start" button. The results will show total number hops and displays a list of all nodes through which the packets passed, indicating the average travel time.
Using the Lookup utility, you can easily find out the domain name by IP address, or perform a reverse lookup.
It's just as easy to get detailed information about the domain or IP address by activating the "Whois" tab. Developer: AutoNOC

Spreading: free Trace3D - handy utility to visually display the path of the packages. The program can be downloaded and used completely free of charge (there is no Russian localization). To run a trace, simply enter an IP address or hostname and click the "Go" button. The trace results are displayed in the form of a table and 3D graphics, on which different colors shows the minimum, maximum and average packet transit times. The table shows the names of intermediate hosts and the travel time of packets on each leg of the path. When viewing the graph, you can rotate, move and scale. It is easy to visually determine on which part of the network there are difficulties in passing packets.
Visual Trace Route 0.8
Developer: IT Lights Software (the utility is no longer supported by the developer, but it can be found on software portals, for example,) Distribution size: 595 kbSpreading: Free Visual Trace Route - simple utility for visual tracing. The program can be downloaded and used completely free of charge (there is no Russian localization). There are no difficulties in conducting visual tracing in the Visual Trace Route. You need to enter the IP address or hostname in the field provided for this and click on the "Start" button. The results will be presented in the form of a table. It displays the number of clicks, IP addresses and names of all intermediate nodes, the average time of packet movement (in numerical and graphical form), as well as TTL data at each stage of the path.
HyperTrace 2.03
Developer: AnalogXDistribution size: 347 kb
Spreading: free HyperTrace is a simple visual tracing utility. The program can be downloaded and used completely free of charge (there is no Russian localization). Tracing here is organized extremely simply - you need to enter the IP address or host name in the field provided for this and click on the "Trace" button. The results are presented in the form of a table displaying the IP address, hostname, as well as TTL and Loss data for each stage of the path. By default, the percentage of missing packets is not indicated, so you will have to activate the corresponding function in the settings ("Config" button). To be honest, we had doubts about the Loss data, since the program for any server, if one was available, consistently indicated 0%, while other utilities were not so loyal.
⇡ Conclusion
We tried to review several well-known diagnostic utilities, as well as online services. We honestly admit that for such multifunctional solutions as VisualRoute, 3d Traceroute and NetInfo, far from all the possibilities were considered, but only those that may be of interest to the average user. The list of these programs includes both free and paid solutions. Free utilities(but not free editions commercial products) from the built-in Windows Utilities Tracert differ only in more convenient application, but no additional information they do not provide (see table). Another thing - paid programs, which not only replace the built-in Windows programs Ping and Tracert, but also turn out to be much more informative than them. Plus, commercial diagnostic utilities provide visualization of testing processes, as they display them in one or another graphical form. Especially from all these points of view, the VisualRoute utility stands out.table. Functionality of utilities for network diagnostics

There are several ways to check the data transfer rate on a local network. If your local network is based on WiFi connections, then, of course, the data transfer rate will differ significantly from a wired connection.
Now do the same on the other computers on the local network. Knowing the IP address of each computer, all you have to do is enter a command in the console to send the packet.
To do this, open the console again and enter: Ping (ip address of the computer), after which you will see a packet sending window where the average packet sending speed will be written below.
Program for testing the speed of the local network
Finally, you can use programs to measure the speed of data transfer in the local network. There are a lot of such programs, both paid and free.
Consider a speed test using the example of the LAN Speed Test program, which you can download on the Internet without special problems. The program does not require installation.
After starting the software, a window will open where you will need to specify any folder on your computer to send the report and click the "Start Test" button.
After a few seconds, the program will display the result of the local network speed test:
The only negative of the program is that it is shareware, so for more specific reports you will have to purchase a license.
Before you write "nothing works for me", try to find out what specifically does not work for you.

ipconfig /all
nslookup
ping [host address (for example, ya.ru) ] [-n 20]
pathping [host address]
tracert [host address]
ipconfig /all shows settings network interfaces.
Everything that is indicated there must be checked with the user's memo (if the memo is old, then check with the data that was issued technical support). See the website for how to set up the connection.
ping [-t] shows the response time from the specified host. Large delays can indirectly serve as an indicator of a slow resource (a busy channel, weak resource hardware, and similar problems). The [-t] key is used to execute the command before the user interrupts it by pressing "Ctrl+C". By default, without this key, ping will only run four times, which is not always enough.
pathping Shows the response time and the number of missing packets along the route to the host.
tracert
For graphic display problems, you can download the PingPlotter program from the local network
nslookup
Verify DNS work.
Check algorithm: Error " Network cable not connected"
1. Check cable connection in network card
2. Check the integrity of the cable up to the shield.
3. Call Tech. support.
The network cable is connected, but there are no incoming packets.
1. Check the cable connection in the network card (you can remove and insert the cable into the socket).
2. Disable all firewalls (firewalls), if you have them.
3. Ping the gateway (take the address from the connection settings or from the connection details in the control panel).
4. Call Tech. support.
The network cable is connected, there are incoming packets, but do not go to the internal services:
1. Disable all firewalls (firewalls), if you have them.
2. Check DNS operation (nslookup).
3. Check connection with these servers (ping)
4. Check connection with central servers. (ping online.vo, ping 192.168.0.250, ping address _your_gateway)
5. Check browser settings
5.1. Internet Explorer-> "Tools" menu -> "Internet Options" -> "Connection" -> "Network Settings" -> check if the checkbox "use a proxy server" is disabled
6. Call Tech. support.
DNS check:
The nslookup server command should return the ip address of that server. For example, the command "nslookup vo47.ru" should return the address "193.106.108.68"
Diagnostic Commands
| Command | Purpose | Launch Format | Example |
|---|---|---|---|
| ipconfig | Shows network interface settings | ipconfig /all | |
| netstat | Shows the route table | netstat -nr | |
| nslookup | Refers to the DNS server (if not specified, it is taken from Windows settings) to resolve a computer's DNS name to its IP address, or vice versa | nslookup DNS-name_or_IP-address DNS-server_IP-address | nslookup vo47.ru nslookup ya.ru 193.106.108.67 |
| ping | Checks the connection with another computer and the speed of the response. It is not a tool for measuring connection speed. |
ping DNS-name_or_IP-address | ping www.vo47.ru ping 193.106.108.97 |
| tracert | Same as ping, but with information output for all intermediate nodes | tracert -d DNS-name_or_IP-address | tracert -d cs47.ru |
| pathping | Same as tracert but more detailed view and indicating the percentage of losses | pathping DNS-name_or_IP-address | pathping vk.com |
