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.”

This is a true and trusted test of your Internet automatic speed. Tests sizes auto adjust up to 200 MB depending on your Internet connection type. Manual tests sizes over 12 MB have the automatic forwarding feature disabled. Randomized speed test data, each download test is dynamically created on the fly so no two tests are alike.

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

One way to get an idea of how well your Mac is working is to run benchmarks and a set of performance tests on your MacBook or Mac desktop. Your CPU as well as your WiFi internet speed and even. Internet speed tests, like this one or the test found atSpeedTest.net, measure the latter, or the speed reaching the device running the test. These test results are often lower than your plan speed due to various factors outside your Internet provider's control, including WiFi conditions and device capabilities.

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.

Internet Speed Test For Imac

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.

Other frequent factors influencing throughput:

• 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?
This notice is in place to protect our test from being stolen and run, mirrored, or framed into another website.

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.

How do I save my bandwidth test results?
Your most recent speed test results are saved in your Results History when tested on desktop or tablet.

This internet connection speed test checks the speed of your internet connection - along with a good portion of extra details like ping, jitter, upload and download speeds, streaming latency, and packet loss - and gives you comprehensive feedback on which kinds of functions their network is capable of performing. These functions include things like VoIP (or voice over IP), live video buffering on Hulu or YouTube, game playing, and others. In contrast to most internet speed checks, Wirefly's speed test runs without Javascript or Flash. Instead, it employs the more widely functional HTML5, a programming language that enables the test to operate on any device, such as laptops or mobile phones. As the speed test runs, the animated speedometers will activate and supply users with the details of their online connection speed within 30 seconds.

How to Determine if a Connection is Good Enough for VoIP

The first step is to test the network to determine the speed that it is operating at now. If the results are adequate, then the connection can handle VoIP. Inadequate results, on the other hand, may be fixed by carrying out these tasks:

Internet Speed Test App For Macbook Pro

• Determine how many units are connected to the network. The more units on a network, the less available bandwidth, a concept frequently called a “network blockage.”
• Check the wires. Insufficient test results sometimes happen because of unconnected cables or worn out wires in the network.
• Upgrade the machinery. Outdated units (such as routers or modems) often substantially decrease the speed of a network.

The speed test on this site is designed to deliver an in-depth report that covers a connection's speed, quality, data packet rate, and other important details. It will help users to gain a clearer understanding of how their existing web connection works and if it can handle VoIP service. If your internet connection is not as fast as you'd like it to be, you can compare internet providers to find a better ISP.

The Components of a High-Quality Internet Connection

Determining the speed of a connection is absolutely essential, because the findings will allow you to identify what applications it can effectively support. In basic terms, these speed test results indicate how quickly information passes through a network. This is particularly vital for VoIP service, which requires a strong web connection to transmit, assemble, and receive packets of information, which are then converted into sound files.

Another important factor to look at is the kind of VoIP service that is required, namely either business VoIP or residential VoIP.

With business VoIP, it's essential to consider how a connection's bandwidth is allocated. A network's devices must all share bandwidth, and as a result, the greater the number of devices or employees tied into a connection, the more slowly that connection will execute tasks.

With residential or household VoIP, the connection is distributed to all units in the home. Web games, downloads, movie streaming devices, cell phones, and laptops are common functions for a household web connection. However, there could be other elements slowing down a connection's general speed. Some ISPs transmit information in different ways depending on what they think are favored functions for a household network.

What the Speed Test Results Indicate

Once the speed test has run, users are supplied with several different results for different measurements. Below is a brief explanation as to what your test results mean in relation to your current broadband connection:

• Ping or execution delay: A measure of how long it takes one data packet to be dispatched from one PC to another and then return.
• Jitter: A measure of several ping results in a row. A good jitter figure should be very close to zero.
• Download Speed: Rather than a pure measure of speed, this figure shows the number of bps that may be downloaded by one unit from another through the web.
• Upload Speed: Like the download rate, this is not a true speed measurement but simply indicates the number of bps that may be uploaded between computers through the web.
• Bufferbloat: A latency test that is executed whenever a connection is experiencing low bandwidth. Normally, this is accomplished by performing a bandwidth check to enhance the connection's speed.
• Data Packet Loss: This test measures how many packets of information reach their specified arrival point when dispatched from a PC. The best figure for packet loss is 0%.

Ways to Boost Connection Speed

In order to achieve maximum internet speed efficiency, users must have a dependable and fast-speed web connection. With that in mind, there are a couple of steps that can be taken to enhance an existing web connection and make sure it's running at the quickest speeds achievable:

Internet Speed Test For Mac

• Perform the network speed test on this page. Using this speed test is an important first step in determining the speeds a connection is presently operating at. If the results shown are suitable for VoIP service, then it's safe to say that the connection itself is not the culprit.
• If the results displayed are unsatisfactory, it will be necessary to first determine how many other units are sharing bandwidth. This will ideally entail creating a checklist of all telephones, laptops, PCs, et al. that are presently sharing the web connection.
• Users should never use a wireless connection to test speeds or operate VoIP services. It's best to connect the VoIP unit right to the modem provided by the ISP. This will enable users to immediately gain entry to their household or commercial network to investigate any problems, which protects against any remote disturbances that might hinder the test's ability to perform.
• If the speed test findings are still less than satisfactory, the problem is probably with the ISP. They will have to be directly contacted for assistance in order to ensure that a network can handle VoIP services. On the other hand, if the results displayed are sufficient, then it's probably safe to say that the residential and/or commercial network is causing the latency.
• In order to properly evaluate residential and/or commercial network problems, the PC will need to be connected straight to the unit that sends input to the modem, which would generally be the router. Once the connection between these two units has been established, the speed test must be performed once more. Adequate results indicate that the network supporting the router is the problem, at which point the ISP and router can be eliminated as possible factors.
• Next, users should check the upstream path of the network's wiring. It will be necessary to perform the same procedure mentioned above again on all the units that are linked to the network, which essentially means conducting a speed check on every unit until the results become poor. This allows users to identify the location of the issue in their network. At times, the remedy is something as easy as swapping out a worn Ethernet wire or damaged hardware component.
