Maximum data speed in a LAN depends on the type of technology you are using. For example, if you deploy 10GbE in the LAN, you can expect data speed up to 10,000 megabytes per second. In the latest versions of power over Ethernet, you can get up to 100 Gbps. But this is only possible if your access to bandwidth and performance is comfortable.

Nowadays, internet technology has progressed a lot. Do you know why? It is because of increased internet connection requirements and network performance. When we land at the speed of the switches or networks, we consider many factors. This guide will explore multiple factors contributing to the maximum speed of LAN and playing a crucial role in maintenance.

What is LAN? And How does it work?

LAN, or local area network, refers to the number of devices connected to the network and driving data from the switches in the local area. Unlike Wide-area networks, LANs have some distance limitations. For example, if you implement the LAN in your office, it would limit its distance in the office. That’s why all the networks in buildings, schools, and other such places are LANs.

A LAN might comprise:

  • Switches
  • Ethernet cable
  • Router
  • Computer

Today, we are moving forward to virtualization and expanding our networks widely. So, you can observe the extended virtual networks with a few hardware devices!

Now, the question is — how does LAN work?

Here is how you build a data connection:

  • Employ Ethernet switches or wifi for wireless access points.
  • Link your devices with the switch or wifi.
  • Deploy the routers to improve the network performance and monitor the traffic.

Depending on your technology, you will get the data speed from your LAN. Such networks are available in buildings, offices, schools, medical centers, etc.

Three ways to measure the speed of the LAN

Do you want to measure the data speed of your LAN network? Remember, the theoretical and practical maximum speeds of the internet connection are pretty different. Several factors decrease the network’s full speed.

However, we will measure the actual speed of the LAN network here. Three methods are as follows:

LAN Speed Test

A LAN speed test is software that runs on your computer and checks your network’s maximum speed.

Here is how you can check speed with this tool.

  • Create a shared folder on your computer. Copy a file from your computer and paste it into the shared folder. You can do the opposite to ensure your computer works fine and can read and write the files.
  • Download the software LAN speed test from Google and run it to move ahead with your speed test.
  • In the LAN speed test tool, click the Select Button. Select the shared folder on your computer and click Start Test.
  • Specify the size of the file you want to transfer. If it is 1 gigabyte, start the test.
  • After the test ends, you will get all the details with the time taken for the file transfer.

This tool lets you get your test report and check it later. Moreover, it helps determine the maximum speed of the LAN network so you can understand how fast you can transfer your file.

Net Stress

Like the LAN speed test, Net Stress is a software program that helps diagnose speed. To find your local network’s maximum speed, follow the procedure below.

  • To use this test, you have to choose two computers and download the Net Stress software on both computers.
  • You must locate the Net Stress Application file and run it as the Administrator to complete the installation process.
  • Do the same process on your second computer to install the program successfully and establish a firewall exception.
  • Locate the option”Remote Receiver IP” and click on it to get the IP address of the second computer and connect both devices simultaneously.
  • You can go to Settings and choose the units for your results. If you want it in Kbps or Mbps, choose as per your requirement. The bigger the measuring unit, the easier it will be to determine the speed.
  • Go to Settings again and find the TCP and UDP Settings. In the menu, you can choose the Segment size and set the number of TCP and UDP transmissions to include in the test.
  • Click Start to begin the testing process. This will ensure that you get the maximum speed of your LAN.

Later, you can exit both computers and know the upper limit of your LAN speed.

Net Meter

Net Meter is another efficient tool that helps determine the maximum speed of your LAN network.

Similar to the above methods, you can get at it as:

  • Go to Google, Download the Net meter from a trusted website, and run the program on your computer.
  • Check out the Net meter speed graph to ensure what it is showing. When you are not using the data, it will display zero speed. However, to analyze the speed, you can transfer, download, and play video games to check out the speed every moment. You can get all the data related to your LAN speed.
  • You can customize the speed graph by adjusting the color and other options in the graph setting. Once your job is done successfully, you can exit the tool.

The whole process is simple and effective. Go ahead with your speed test right away!

4 Technologies to determine the speed of the LAN

We consider several technologies that could help determine the maximum speed of the Ethernet connection. For example, if you have employed Fast Ethernet, you will get 100 Mbps and 1 Gbps with Gigabit Ethernet.

Your technology plays a greater vital role. Let’s consider the four fundamental technologies.

Fast Ethernet

Have you heard of Fast Ethernet before? Before 1996, we had to rely on Fast Ethernet. In other words, it was the first Ethernet Standard to provide users with data speed.

So, what is the maximum speed of Fast Ethernet?

There are no surprises. You can get a maximum speed of 100 Mbps. Usually, Fast Ethernet switches have a symbol for 10/100 Mbps data speed, which is a range of speeds.

So, how will it determine the speed of the LAN?

It is pretty simple for a home network. If you have installed the Fast Ethernet switch, you will expect the upper data speed limit to be 100 Mbps, and the lowest limit will be 1 Mbps. Depending on megabits per second speed, we can understand the maximum speed of your LAN.

Gigabit Ethernet

In Gigabit Ethernet, we have the lower threshold of 1 Mbps, and the maximum data speed will be in gigabytes.

Usually, we have:

  • 1 Gigabit Ethernet
  • 10 Gigabit Ethernet

1 Gigabit Ethernet can provide a maximum speed of 1000 Mbps or 1 Gbps. In the case of 10 Gigabit Ethernet, you will observe the maximum speed of your data is 10 Gigabytes per second. However, depending on your Gigabit technology, you can explore 25 Gbps, 40 Gbps, 100 Gbps, and more.

So, a LAN comprising the 10 GbE switch will have a maximum speed of around 10,000 megabytes per second. A similar concept applies to other Gigabit Ethernet versions. Thus, you can have a rough estimate of maximum data speed.


Power over Ethernet is a technology that provides data speed and power over a single Ethernet port. It has different standards introduced by the Institute of Electrical and Electronics Engineering.

Here are IEEE standards.

The maximum power and speed of a PoE network depend on these standards. If you use IEEE 802.3bt, you will get 100 watts, while the low power applies to the other methods. The PoE standard can also give you an idea of the data speed and maximum power.

Network speed varies in the power over Ethernet. It depends on the type of switch you employ for your PoE technology. For example, if you use the Fast PoE switch, the maximum speed will be around 100 Mbps. Similarly, you can get 100 Gbps data speed with the PoE switch.

However, to build the PoE network, you can get your devices and link them with the switches’ Ethernet ports.

Now, the question is — how do you determine the PoE switch speed?

The above methods can provide information. Sometimes, the maximum data speed is written itself. If it is not registered, you can apply the above techniques.

Wi-Fi or wireless access points don’t employ wires, unlike the PoE or Ethernet systems. You can get an idea from the wifi system as well.

If they have the standard 802.11a, the maximum speed will be around 54 Mbps. Similarly, the speed will be higher for other principles.

The standard 802.11n provides a maximum speed of 450 Mbps. The maximum rate per second is especially noticeable on Wi-Fi devices. Service providers offer a lower speed in homes with small networks compared to offices with high networks. Depending on your requirements, you can install the system and overcome internet issues efficiently.

The latest Wi-Fi standards offer a maximum speed of up to 750 Mbps near Gigabit Ethernet.
