Speed Test Plus, Explained

How does our Bandwidth Test work?
The MegaPath Speed Test Plus checks speed and overall quality of the connection from your broadband provider. Simply select the nearest city, then start the test as either a business or residence – we’ll take care of the rest!

Going beyond Internet speed with Speed Test Plus
So what’s with the “Plus”? Most Internet speed tests start and end with download and upload speeds. We’ve decided to take this a few steps further, leveraging our decades of industry experience to formulate new performance quality benchmarks—latency, packet loss, and jitter—that directly affect the day-to-day realities of today’s businesses.

What needs to be installed to run the Speed Test Plus?
Adobe® Flash is required to run MegaPath’s Speed Test Plus.

Why should I test my Internet speed and quality?
A broadband bandwidth test is an effective way for individuals and businesses to keep tabs on their connection. Broadband providers sell tiered packages based on speed, so it’s vital to test regularly to make sure you are getting the appropriate return on investment. For businesses using VoIP services, broadband speed and quality is essential for the day-to-day work of each and every employee. From client calls to data analysis, the quality and reliability of your broadband connection has a huge impact on your bottom line.

Understanding your bandwidth test results:
MegaPath’s Speed Test Plus goes beyond just download and upload speed. Let’s look at a few important measurement terms used in our bandwidth test:

For business users, you should have enough downstream capacity to accommodate office needs. VoIP calls, video streaming, web browsers, and email transfers all require downstream throughput. Upload speed is critical for making VoIP calls, sending large files, and hosting websites.


Why is my Internet speed lower than expected?
Several factors may slow your connection, resulting in lower-than-expected Internet speeds. Try these suggestions:

  1. Stop any downloads or programs that may be using your connection while running the speed 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 run the speed 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, T1 or DSL 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.
  • Latency
    In a network, latency, a synonym for delay, is an expression of how much time it takes for a packet of data to get from one designated point to another. In some usages, latency is measured by sending a packet that is returned to the sender and the round-trip time is considered the latency. Low latency is extremely important for businesses and power-users.
  • 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.

If you routinely experience lower-than-expected Internet speed results, contact your broadband provider for troubleshooting assistance.

Other frequent factors influencing throughput:

  • The number of devices sharing the access circuit and the activity the other devices are generating while testing Internet speed on one of the devices
  • 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 test client and the server

Why do I get “Unknown” for Packet Loss?
An Unknown result occurs when the Packet Loss portion, which requires Java, cannot initiate. As most common browsers have stopped supporting Java, it is likely that you will often see “Unknown”. However, you can still assess the quality of your broadband connection by considering your results for the other four variables: upload speed, download speed, jitter, and latency.

Why do I need to install a recent version of Adobe® Flash?
Flash is used to both run the actual test and display the results. The MegaPath Speed Test Plus requires the newest version of Adobe’s Flash plug-in to be installed on the browser you are using for the test. We use JavaScript to detect Flash versions. The upgrade message is displayed if the version of Flash in your browser will not support the needs of the test.

I have a recent version of Flash, why isn’t it working?
Windows OS will sometimes state that an up-to-date version of Flash is already installed when you try to update for a browser that’s not flagged as your “default browser.” Make sure you are installing updates on the browser you are using for the bandwidth test. You can do this in your browser’s settings, under Plug-ins or Add-ons.

I’m having trouble running the test in Firefox. What should I do?
Check to see if Flash plugin is installed and enabled in Firefox. Go to the Firefox menu, select “Add-ons” and look for Shockwave Flash. If it is not there you will need to go to the Adobe website and download the flash plugin.

How do I re-enable Flash in my Firefox browser?
Mozilla has stated they are blocking Adobe Flash as a default, until Adobe is able to satisfactorily update Flash’s security from publically known vulnerabilities. The most up-to-date version of Flash is protected from some of these vulnerabilities.

To reactive Flash in Firefox, do the following:

  1. In a new FireFox browser tab, go to “about:addons” and select Plugins
  2. Find Shockwave Flash [version]
  3. Select either Always Activate or Ask to Activate
  4. Continue to enjoy MegaPath Speed Test Plus!

Why do I see a license expiration notice?
The license notice protects our speed test from being stolen and run, mirrored, or framed into another website.

To remove this notice:
Make sure you are going to We have software in place to block our bandwidth 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 MegaPath cookies should make the license expiration notice disappear.

How do ad blocks and firewalls impact the test?
Our speed 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 bandwidth test to work. Be sure to turn it back on before leaving our website.

How do I save my test results?
Your most recent Speed Test Plus results are saved in Your Test Results History, when tested on desktop or tablet. If you do not see a saved history, please make sure that cookies are enabled in your browser settings.
