Computer networking is a complex topic. In this article, we'll be taking a deep dive on the nuances of network performance for those who need some additional explanation while striving to be concise, and to educate users of various experience levels relating computer hardware and computer networking.
If you just need to know how to perform a network performance test/benchmark, jump down to configuring iPerf.
Core Network Concepts
LAN vs WAN
With regards to network performance, it is crucial to first separate whether an issue is with Wide Area Network (WAN) performance, or if the issue is with Local Area Network (LAN) performance.
Your LAN is essentially the network inside your home or business. Many homes use a combination modem/router device provided by their Internet Service Provider (ISP). In some cases, especially in businesses, you may have a separate modem and router, along with other equipment connecting to the router such as a network switch.
Your modem, and the connection it establishes to your ISP—whether through coaxial cable, fiber, phone lines, or long-range wireless—essentially marks the point between the WAN and the LAN. The connection your modem makes to your ISP is the WAN, and any devices you connect through your router behind that modem belong to the LAN.
Link Rate
Almost every type of connection your computer makes to any piece of hardware will have a link rate of some kind. The link rate establishes how fast data can possibly be transferred across any given connection, but it does not guarantee how fast the hardware on either end of the connection will actually transfer data.
The concept of link rates, and their related bottlenecks, is likely best conveyed by giving an example of what connections might be involved in transferring a file from one computer on your LAN to another.
800Mbps—The file source is a USB 3.0 thumb drive capable of 100MB/s (800Mbps) read/write.
480Mbps—The USB 3.0 thumb drive is plugged into a USB 2.0 port on the PC, which has a maximum throughput of 480Mbps
1000Mbps—PC1's Ethernet connection establishes 1Gbps (1000Mbps) link to the router via Ethernet
300Mbps—The router connects to a second PC (we'll refer to this as PC2) via Wi-Fi, and it has established a 300Mbps link to the Wi-Fi adapter on PC2
480Mbps—The Wi-Fi adapter on PC2 is connected via a USB 2.0 port. The link rate of the USB connection to PC2 is at 480Mbps
6000Mbps—PC2 is going to store the file on an internal hard drive with a link rate of 6Gbps
1600Mbps—File Destination: SATA hard drive capable of 200MB/s (1600Mbps) read/write.
Following this chain, we see that 300Mbps is the slowest link rate established. This means that, regardless of the link rates established elsewhere, the absolute maximum the data can possibly be transferred is 300Mbps.
if we were to change the Wi-Fi connection to a wired Ethernet connection capable of 1Gbps, our performance bottleneck would then become the USB 2.0 connection to the USB drive where the file is stored.
Ports and Interfaces
Interfaces
A network interface represents connections, whether wired or wireless, that are made to form a network between devices.
Ports
Some may refer to physical hardware connections as "ports". For the purposes of networking, ports are logical constructs that can also be referred to as "network ports". Each network interface has 65,535 of these logical ports. Each port on a network interface is a separate data connection.
Benchmarking Network Adapter Performance
To properly benchmark network adapter performance, we need to:
Use a simple LAN configuration
Eliminate bottlenecks, especially link rate bottlenecks
Websites like speedtest.net, fast.com, and other performance tools in your web browser are going to use your WAN connection, and are not appropriate for determining if a network adapter is working well.
Transferring files from one computer to another on your LAN is typically not the best way to benchmark a network adapter. File transfers are bottlenecked by a number of things, including performance limitations of the disk the data is on, and often times a lack of establishing parallel network connections to perform the task.
One of the most accurate ways to benchmark network performance on a LAN is by using iPerf . To more effectively benchmark network adapter performance, it is best to establish a point-to-point connection between two PCs, rather than connecting through a router or switch.
Next, you'll need to run iPerf in client mode, targeting the IP address of the server/interface where iPerf is running in server mode. Additionally, we'll run the test for 30 seconds using -t 30 and with four parallel connections using -P 4. Running 4 parallel connections is optimal for saturating a network link.
Windows
Open Command Prompt
Press Windows Key + R or + R, then enter cmd in the window that appears
Search the Start Menu for Command Prompt, and open it
Navigate Command Prompt to the directory the directory where iPerf is located
The cdcommand is for 'change directory'
If you have a folder named 'iperf' on your Windows desktop, you can reach it in command prompt with the command cd %USERPROFILE%\Desktop\iperf
Run iperf in client mode via Command Prompt (replace 192.168.0.200 with the IP address of the server/interface where iPerf is running in server mode)
iperf3.exe -c 192.168.0.200 -t 30 -P 4
macOS / Linux
Open Terminal
Run iPerf in client mode (replace 192.168.0.200 with the IP address of the server/interface where iPerf is running in server mode)
iperf3 -c 192.168.0.200 -t 30 -P 4
iPerf should start performing a network performance test. If the test fails to start, make sure that iPerf is not being blocked by your PC's/Mac's firewall.
Why iPerf is Ideal for Benchmarking
Unlike a file transfer, iPerf runs in memory on the PC and generates data to send using the CPU directly. This alleviates potential bottlenecks generated by storage devices, and allows you to explicitly control how many parallel connections are being used to transfer data rather than being unsure if parallel network connections are being used by other means.
Conclusion
There's a lot more to networking that isn't covered in this article, but we hope this helps explain enough to get an accurate measure of your network performance.

Update: A Windows 10 driver now exists for the USB2-E1000. However, it will not appear in the CD that comes with the adapter until the next lot of adapters is shipped. The updated driver can be downloaded from this link: Windows 10/8/8.1, 7, Vista, and XP drivers for USB2-E1000.
If you are not able to connect to the Internet without installing the driver, you can download it onto a flash drive on another computer and use that to install it.
In testing Plugable’s USB-Ethernet adapters with Windows 10, we were happy to discover they all work successfully when their drivers are properly installed. However, an installation problem could cause issues with the USB2-E1000.
Drivers are already built into Windows 10 for: the ASIX AX88772 chip in our:
*Note In 2017, our USB3-HUB3ME was redesigned to include a Realtek RTL8153 chipset and drivers. Windows 10 should automatically configure these drivers when you plug the adapter in.) When you insert these adapters into a USB port, the drivers should automatically install with no need for an internet connection.
However, the driver for the ASIX AX88178 chip in our USB2-E1000 is not pre-installed in Windows 10, and we have discovered a problem with the downloadable driver that keeps it from installing. If this happens, the adapter will show up in Device Manager as “AX88178” with a Code 28 error: “”Drivers for this device are not installed.”
There are several ways to work around this issue, depending on the scenario:
1. Upgrading from Windows 7 or Windows 8.1: If you have already installed the driver for the USB2-E1000 in Windows 7 or 8.1 and upgrade directly from that version to Windows 10, the currently installed driver will be available to Windows 10, and your adapter should work without any further effort. If you haven’t yet installed this driver, please install it before upgrading.
The easiest way is to establish an internet connection, either wirelessly or through another Ethernet port, then plug in the USB2-E1000. Windows Update should see it and automatically download the correct driver. You can also download and install the driver from our website or from the disk that came with your adapter.
2. Doing a clean install of Windows 10 or using the USB2-E1000 on a new Windows 10 computer: Since the previous Windows 7 or 8.1 driver will not be carried over to a clean install of Windows 10, it must be freshly installed. The only way to accomplish this is to have an internet connection available when you first plug in the USB2-E1000.
That will allow Windows Update to download and install the driver. If you are in a situation where this is not possible, we recommend delaying the update until an internet connection is available, or until this issue has been fixed. Currently, the driver on the Plugable and ASIX websites is not working with Windows 10.

The Raspberry Pi Zero 2 W is a versatile single board computer that can be used for a variety of projects, and by people of varying skill levels. The compact form factor and ability to use open source operating systems and software makes for a great learning tool, and we were able to pick one up!
This guide will show you how to set up a headless wired Ethernet connection on your new Raspberry Pi Zero 2 W (and legacy Raspberry Pi Zero) computers with our Plugable USB2-OTGE100 wired Ethernet adapter.
Why use Wired Ethernet?
Adding a wired Ethernet adapter may help improve data transfer speeds, should improve device connection stability, and can reduce wireless traffic. Whatever the goal, our 10/100mbps USB2-OTGE100 adapter can provide wired Ethernet access to Raspberry Pi Zero boards via USB Micro. The adapter uses an ASIX AX88772A chipset with drivers that are included in Raspberry Pi OS which can make the setup process easier. With that said, we still need to do a little work to get things going, so let's get started!
Note
All steps and tests were completed using:
A Raspberry Pi Zero 2 W board
The official Raspberry Pi Lite OS
Our Plugable USB2-OTGE100 wired Ethernet adapter
We cannot guarantee compatibility with other operating systems or add-on equipment. Check with the developer/manufacturer of your operating system/add-on equipment for help with additional setup. The Raspberry Pi Forums are a great source of information and community!
First, we need to download the Raspberry Pi OS image, which you can get from this link: Raspberry Pi Operating system images. We're going to use the Raspberry Pi OS Lite version for these steps, but, you can also use the full Desktop versions as well. Download the image and get ready for the next step.
Now, we need flash the image to the Micro SD Card. Let's use Etcher, which is an open source tool for creating bootable drives and is available on Windows, Mac and Linux! You can get official information and download Etcher from this link: Official Etcher information and Download.
After you've installed Etcher
Open Etcher and click Flash from file, which will open a file explorer window.
Then, click on the operating system image that you downloaded, and then click Open to move on.
Now, we can see that we have the image picked and ready to be flashed onto the SD Card, so go ahead and click Flash! to begin.
Flash Complete! Great, now let's close out of Etcher, and get ready for the next step.
Now that we've finished flashing the image to the card we need to give the Raspberry Pi instructions to use SSH (Secure Shell) automatically when it boots up.
Secure Shell is a network protocol that will allow us to remotely access the Raspberry Pi Command Line Interface (CLI). This is very helpful for our initial setup, and can be used to access the Pi on a regular basis without having to set the Pi up with a mouse, keyboard and monitor.
We'll be using PowerShell here as the program is likely already installed on your Windows computer.
Open Windows PowerShell, and enter New-Item .\Desktop\ssh into the terminal. This will create a blank file named "ssh", on your Desktop view which we'll copy over to the card.
Note
For macOS and Linux, open up a Terminal window, and enter sudo nano Desktop/ssh. This will open up a blank file for editing on the Desktop. Press Ctrl and X to save and exit. This will put a blank file named ssh without a file extension on your Desktop view.
Copy the file on to the card, which will run on boot up and enable SSH automatically.
The next thing that we need to do is to edit the cmdline.txt file on the Micro SDCard itself. This will let us create a special IP address for the Raspberry Pi to make setup easier. Here's how:
Open up the SD Card, and right click on the cmdline.txt file and choose Open. This will open up your default text editing program where we can edit the file. For this example, we're using NotePad on Windows.
You'll see a string of text at the top which we should leave as it is. Go down to the next line, and type in ip=raspberrypi.local. Then, save and close the document.
Now, we are ready to communicate with the Raspbery Pi using ssh! We're going to use PowerShell on Windows, and the default terminal on macOS and Linux to get this job done. There are many other ssh clients available such as PuTTY and Termius, and more. You may want to take some time later to find the best program for you.
Open PowerShell, and enter ssh pi@raspberrypi.local into the terminal.
A message will pop up stating that the authenticity of the host can't be established. This is normal when you try to make a new connection, and will happen the first time you connect to the Raspberry Pi.
You'll be asked if you want to continue connecting. Type yes into the terminal, and press enter. This will add the Raspberry Pi to the list of known hosts for your computer.
Finally, type the default password in which is raspberry and press enter to login. (NOTE - the password won't actually show up here for security)
Now that you're logged in you can start using your Raspberry Pi! Here's a few suggestions of things you'll likely want to do to complete your setup:
Change your password. Enter passwd into the terminal (no, that's not a typo!). This command will let us change our password. NOTE - by default, you will not see the password characters as you type.
You'll be asked to enter the current password, which is raspberry
Then, enter a new password, you'll have to re-type it to make sure it matches. Once you have a match you'll have successfully changed the password
Use the Raspi-Config tool for further system setup. Enter sudo raspi-config into the terminal and you will be taken to the Raspberry Pi Software Configuration Tool menu.
Edit the cmdline.txt file if you'd like so you can use an actual IP address. Enter sudo nano /boot/cmdline.txt into the terminal. Delete the line that says ip=raspberrypi.local, or comment it out by putting a # before the line, like this, #ip=raspberrypi.local This will change the color of the text and comment it out, or essentially disabling it without having to delete. Then, press Ctrl and x at the same time to save and exit the file.
Set a static IP address. You may want to set a static IP address that doesn't change, which will make it easy to identify your Raspberry Pi. Enter sudo nano /etc/dhcpcd.conf into the terminal which will open the configuration file for our Dynamic Host Configuration Protocol (DHCP) settings. Follow the sample instructions in the file to create static information for your Raspberry Pi.
An Iperf test will help us test the network throughput of the connection to see where our speeds rate. We see an average of 94.5mbps for download speeds, and 94mbps for upload speeds. These results were taken from a 2-minute test registering the speed at every second, which is definitely on target for 10/100mbps! Here's a handy chart for visualization.
We hope this was helpful, and fun! Feel free to reach out to us directly at support@plugable.com. We'd love to see what Raspberry Pi projects you're working on!

I am still unable to get my Ethernet connection working on my Mac
If this is the case please reach out to our support team. When you do please include a diagnostic log gathered using our PlugDebug tool (instructions are provided on the PlugDebug page). If you are not able to gather the PlugDebug diagnostics do not worry we are still here to help! Please reach out to our support team at support@plugable.com or Plugable.com/Support with a detailed description of your problem, and the model of Plugable product you are using.
One helpful way to identify your ethernet link rate speed is through the System Settings app in macOS. This can help us identify if your Plugable ethernet adapter is negotiating either 1Gbps or 2.5Gbps network speeds. Some routers have a mix of 1Gbps or 2.5Gbps ports, and in the macOS System Settings this will be shown in the Speed field.
In this example, we will be analyzing our USBC-E2500, which is a 2.5Gbps ethernet adapter. This method applies to all of our ethernet adapters, such as:
Navigate to the Network section, select the entry named “USB 10/100/1G/2.5G LAN” with the Green - Connected icon. Expand the Details button, and go to Hardware.
In the field that says Speed, you should see 2500Base-T if the ethernet adapter is connected to a 2.5G ethernet LAN port on your router. If you see 1000Base-T, this means the adapter is connected to a 1G ethernet LAN port. If you are expecting faster network speeds, please see your router's documentation on its multi-gig LAN port.
