Starting with Windows Vista, users can see how much bandwidth a USB controller has allocated by checking the controller's properties in the Device Manager. Select the controller's properties then look under the Advanced tab. This reading does not indicate how much bandwidth.

How to test internal LAN network speed? In order to test and troubleshoot networks we need tools that allow us to generate network traffic and analyze the network’s throughput performance. This is true for both wired and wireless networks. In order to properly troubleshoot a wireless (or wired) network we need a way to benchmark its performance, so as modifications are made we can determine whether or not they really make a difference in the network’s performance.

This is where these LAN benchmarking tools fits in to test network speed between two computers. The concept is you install a new wireless network and it works perfectly. Run these tools and record the benchmark results for later reference. Sometime in the future when either you or others suspect performance has declined then run these tools again and compare the latest results with those you gathered when the network was first installed and working perfectly.

↓ 01 – LAN Speed Test Lite Windows macOS

LAN Speed Test was designed from the ground up to be a simple but powerful tool for measuring file transfer, hard drive, USB Drive, and Local Area Network (LAN) speeds (wired & wireless). First, you pick a folder to test to. This folder can be on a local drive or USB drive, etc. to test the drive speed, or a shared folder on your network to test your network speed.

Next, LAN Speed Test builds a file in memory, then transfers it both ways (without effects of Windows/Mac file caching) while keeping track of the time, and then does the calculations for you. For more advanced users, you can test to LAN Speed Test Server instead of a shared folder to take the slower hard drives out of the process as you are testing from one computer’s RAM to another computer’s RAM. Simple concept and easy to use. You’ll find that LAN Speed Test will quickly become one of your favorite network tools!

• Test the speed of your Local Network by testing to/from network shared folders
• Test the speed of your local drives (USB Drives, hard drives, etc.)
• Compatible with LST Server (v1.5 or later) for real network performance results without hard drive limitations – Even test your WAN (Internet) speed with LST Server
• Ability to choose Network Interface Card for computers with multiple NICs

• Supports both TCP and UDP data transfers
• Supports multiple data streams
• Variable TCP / UDP segment size
• Rate of packet transmission (Packets Per Second)
• Variable Maximum Transmission Unit (MTU)
• Uplink and downlink modes
• Auto node discovery
• Choice of display units (KBps, Kbps, MBps, Mbps)
• Support for multiple network adapters

↓ 07 – iperf macOS Linux

iperf is a tool for active measurements of the maximum achievable bandwidth on IP networks. It supports tuning of various parameters related to timing, protocols, and buffers. For each test it reports the bandwidth, loss, and other parameters. The current version, sometimes referred to as iperf3, is a redesign of an original version developed at NLANR/DAST.

iperf3 is a new implementation from scratch, with the goal of a smaller, simpler code base, and a library version of the functionality that can be used in other programs. iperf3 also a number of features found in other tools such as nuttcp and netperf, but were missing from the original iperf. These include, for example, a zero-copy mode and optional JSON output. Note that iperf3 is not backwards compatible with the original iperf.

↓ 08 – PassMark Advanced Network Test Free Trial Windows

The network benchmark test will work with any type of TCP/IP connection. Including ethernet, dial up modems, ADSL, cable modems, local area networks (LAN), Wide area networks (WAN) and wireless networking (WiFi). The software has been optimized to use a minimum amount of CPU time, allowing even high speed gigabit ethernet connections to be benchmarked. Users have the ability to change the following test parameters.

• The IP address of the machine acting as the server and the port number used for the test to help with firewall issues.
• The size of the data block used for each send request. It is also possible to select variable sized blocks to measure performance deltas as block size increases or decreases.
• The duration of the test.
• The protocol, either TCP or UDP. The TCP protocol is when data integrity is important (Errors are corrected using data re-transmission). UDP is used with applications that are tolerant to data loss such as video streaming.

Why do I get a “socket error” message?
An error may result from having the speed test open in more than one browser tab or window. The test may fail to complete and display the following message:
“A socket error occurred during the Upload test. Please try again later.”

To prevent this error, and get the most accurate test results, close all other browser tabs and windows before running.

If you continue to get a socket error message, or another type of error message, please provide feedback by emailing us at speedtestfeedback@fusionconnect.com. Please, include your OS/Browser information.

Why is the location I usually pick missing from the City list?
We first complete a latency test to our servers, and if a server does not respond within a specified time frame, it is not included in the City list.

A slow response can be caused by latency or packet-loss between the client and server, or particularly high Internet usage (during peak hours). Do try the test again in a little while.

In which browsers does the Speed Test work best?
For best results, use the most recent version of your favorite browser. But at minimum use Firefox 53, Chrome 59, Safari 10, IE 11, or Edge 13 or higher. If you are unable to see Speed Test, though other content appears on the speed test page, check your browser's security setting. Try lowering the setting from High to Medium-High, or even a bit lower, to allow the broadband test application to load.

Why am I receiving “Could not connect to the Internet” errors when I am connected?
In some cases, firewall and security software can prevent the test from running and generate a 'could not connect' error. Temporarily lowering the severity should allow the broadband test to run. Be sure to turn it back on before leaving our website.

Why didn’t the test choose the server location nearest me?
Our Speed Test automatically detects the optimal server host location for testing, which is not necessarily the closest server host. This is due to real-time network circumstances like number of hops, or current traffic load on each test server. Change the selection using the Change City drop down function directly underneath the Start Test button.

Why is my speed lower than expected?
Several factors may slow your connection, resulting in lower-than-expected speeds. Try these simple suggestions below. But if your slower speeds persist, contact your broadband service provider to see if they can determine the issue.

1. Be sure to stop any downloads or programs that may be using your connection while running the test.
2. When using a wireless connection, there may be wireless interference. Try using a wired Ethernet connection instead.
3. Try rebooting your modem or router and then running the test again.

What is “Throughput” and what factors affect my results?
There are many factors that impact your speed test results. Throughput problems in your local area network, IP or access overhead, and network design all play a role. Please read the definitions and examples below to learn more about these factors.

• Download
  Download is a measure of how fast your connection delivers content to your computer or local area network.
• Upload
  Upload is the measure of how fast content is delivered from your computer or local area network to others on the Internet.
  For businesses or power-users, download and upload speed should match or at least be very close. This is important for applications like VoIP, on-line gaming and other interactive programs. Upload speed is even more important if you are operating a server at your location. If achieving optimal upload speed is a concern, consider Ethernet or T1 services.
• Kbps
  Kbps transfer rate = kilobit per second transfer rate. There are 8 bits in a byte, so we would divide kbps by 8 to get KB/sec transfer rate.
• Mbps
  Mbps transfer rate = megabits per second transfer rate. 1000 kilobits equals one megabit. One megabit per second equals 1 million bits per second. Mbps is the industry-standard used by ISPs.
• MBps
  MegaBytes per second. There are 8 megabits in one megabyte.
• Transfer Rate
• Transfer rate is speed at which data can be transmitted between devices. As files to download become increasingly larger, the highest data transfer rate is most desirable.
• Throughput
  Throughput is the maximum amount of communication or messaging that can be transmitted through a communication channel during an elementary unit of time, usually, in a second.
  Depending on the type of channel, the addressing mechanism used in that channel, the type of messages are being transmitted and how secure the transmission needs to be—along with physical attributes like temperature, humidity and signal-to-noise ratios—actual measured throughput will vary.

An Example of Throughput
You have Ethernet 8.0 Mbps service and need to transmit an email which is exactly 1MB in size You may expect it will take exactly 1 second to transmit that message. But it will actually take longer as the total information that needs to be transmitted is more than 1MB. The total information is called Payload. The channel needs to not only transmit the payload but also some addressing details like where it is coming from and where it is destined to.

The device that sends this email will break down the message into smaller pieces and package them into what are called IP Packets. The size of these packets is usually determined by your Local Area Network. Some have smaller size, so the message will take more IP Packets to transmit; while others may have larger size which needs fewer IP Packets. Each IP Packet also contains an IP Header. This is where the information like the source IP Address, the destination IP Address and additional information about the payload is included. IP Header is usually 20 Bytes (160 Bits) long.

Assuming that this customer uses 100 Byte payload, each IP Packet will now be 120 Bytes long. And that 1MB message will have to be broken down into 10,000 payload pieces. That means to transmit the whole message the channel really needs to transmit about 1,200,000 Bytes or 1.2 MB or 9,600,000 bits. It will take at least 1.2 seconds to transmit all these bytes on this 8 Mbps service assuming that all these IP packets with the payload arrive without any errors and not needing re-transmission. This is called IP Overhead.

Actual Throughput will always be less than line rate of the access service that is communicated by your provider—and this is all based on IP Overhead only. Ethernet services also have a Layer 2 or Ethernet Overhead. Other services may have ATM, Frame Relay or other kinds of Overhead depending on the design. All of this may contribute to a slower bandwidth throughput than what you are expecting.

Network Bandwidth Test Windows

Other frequent factors influencing throughput:

Network Bandwidth Test Windows Server Iperf

• The number of devices sharing the access circuit and the activity the other devices are generating while the test is running
• A rogue LAN port that is clogging the LAN with transmission
• A leaky LAN port which degrades LAN performance
• LAN signaling issues which create a lot of packet re-transmission for the devices on the LAN
• LAN Router with performance issues, low processing power or Deep Packet Inspection and advanced security features like URL blocking enabled
• Wireless Access Points on the LAN side
• Distance (both geographical as well as number of hops) between the speed testing client and the server

Why do I see a license expiration notice?

How To Test Bandwidth On My Pc

To remove this notice:

Make sure you are going to https://www.speakeasy.net/speedtest/. We have software in place to block the test from being used in any other domain.

Also, you may have an older version of the test cached in your browser. Clearing your cache and Fusion Connect cookies should make the license expiration notice disappear.

How does security software and firewalls impact the test?
Our internet broadband test sends packets of empty data back and forth to your computer in order to test your line speed. Since we are a third-party sending a receiving a tiny data packet from your computer to perform the test, some ad block or security services interpret this as an attack and act accordingly. Temporarily lowering the severity should allow the speed test to work. Be sure to turn it back on before leaving our website.
