What is FAST.com measuring? FAST.com speed test gives you an estimate of your current Internet speed. You will generally be able to get this speed from leading Internet services, which use globally distributed servers.
Why does FAST.com focus primarily on download speed? Download speed is most relevant for people who are consuming content on the Internet, and we want FAST.com to be a very simple and fast speed test.
How are the results calculated? To calculate your Internet speed, FAST.com performs a series of downloads from and uploads to Netflix servers and calculates the maximum speed your Internet connection can provide. More details are in our blog post.
What can I do if I'm not getting the speed I pay for? If results from FAST.com and other internet speed tests (like dslreports.com or speedtest.net) often show less speed than you have paid for, you can ask your ISP about the results.
The device speed test checks the speed between your smartphone, tablet, computer, or other device and the internet. You can run the test through a cellular (mobile) network, a wired broadband connection, or your home Wi-Fi.
A gateway speed test checks the speed between your AT&T Wi-Fi gateway and our network. It reflects the speed coming into your home.
Your device speed varies, depending on the number of devices you connect to Wi-Fi, how you use them, their age and type, and Wi-Fi signal strength.

A: To disable background tests on an Android device, go to the "Test Scheduler" under Settings and then toggle the "Allow periodic background test" switch to turn it off. You can also change the scheduled test settings from this page.
Keep in mind that taking scheduled background tests provides the FCC and the public with more accurate and comprehensive crowdsourced information about mobile broadband network coverage and performance across the United States.
A: The scheduler runs as close to the selected frequency as possible. Factors such as energy efficiency, other high-priority tasks, and rate limits may cause a test to not run as originally scheduled. In addition, the Android task scheduler may not run background tests if the device is in use or not on a charger.
A: Within Test History, select Details to show the network performance results of any test listed. Users can also export detailed results of past speed tests (e.g., radio parameters, connection type, location) to an email address by selecting Data Export in the Settings menu.
To conduct a Speed Test or Challenge Speed Test of your mobile/cellular network, first make sure you are not connected to Wi-Fi. If your device is connected to a Wi-Fi network, disable your Wi-Fi connection prior to starting the test. To complete a Challenge Speed Test, the device must be connected to only the mobile cellular network (the App will not allow users to submit challenges over Wi-Fi connections) and must be outdoors or in a vehicle.

A: The App determines the type of connection your device is using at several points during a test. First, the App checks whether the connection is mobile/cellular or Wi-Fi. If the connection is mobile/cellular, the App will also specify the type of network (3G, 4G, or 5G). Some connections display as 5G on the device (such as at the top of the screen), but the data may be carried over a 4G connection. In these cases, the App may record the test as being carried out over the 4G network, rather than 5G.
A: If you are using the App to test your Wi-Fi internet connection, your test results may not be as fast as the speeds your home (or fixed) broadband provider advertises or delivers to your location. Many factors can impact Wi-Fi speed test results, such as the number of other devices using the router and the fixed connection when you run your test or how far away your device is from your router.
A: The FCC is committed to protecting participants' privacy and has taken significant measures to ensure the privacy and confidentiality of App users. The App asks users to provide certain personally identifiable information -- including a name, phone number, location, or identifiers associated with your device -- in order to certify to test conditions, to enable follow-up communication with users, and to ensure that each user can be identified as a subscriber of the provider being challenged.
I'm an LV newbie and want to verify that the connection speed between a PC running LV and a listening system is 100Mbps. Can this be done with LV or do I need an Ethernet test (e.g., BERT or similar) to do this. Pinging the other port can't tell me the connection speed to my (little) knowledge.
The unit-under-test is an embedded system with an Ethernet port that I am to verify is communicating with my test fixture at 100Mbps. I had intended to add an additional NIC to the host PC specifically for this test as the host pc's motherboard NIC is in use with a company network for uploading test data. I had thought it might be as simple as connecting the host's NIC to the UUT Ethernet port, but then figured that I'd have to establish the connection through software and send it some number of packets to satisfy this requirement. At this point I don't know how the UUT's Ethernet port handles a new connection. I probably need to ask more questions of the UUT.
Do you need to verify the actual throughput, or you just need to verify that it negotiated a 100mbit link? If the latter, and if the UUT is connected directly to an ethernet port in your PC (no routers/switches/etc in the middle), there are ways to do that easily by querying the operating system about the network link. For example, you could use System Exec to run the command shown here: -to-detect-the-speed-fast-or-gigabit-ethernet-of-a-network-... and parse the output. There's probably also a way to get this information through .NET properties.
That is a programmatic way of querying it. Use LabVIEW's System Exec function to run the command, then parse the output string to get the connection speed. Or, you could duplicate this code in LabVIEW: -detect-connected-network-speed-on-window...
The right internet speed for you depends on how many devices are connecting to your network and what those devices are doing. For casual browsing and streaming, speeds around 25 Mbps may suffice, while more intensive usage like 4K streaming, gaming, and multiple users might require 100 Mbps or more. Gigabit speeds are excellent for heavy usage and multiple users, while speeds above 1 Gbps are typically overkill for standard home use.

I ping Google DNS continuously. Then I run a speedtest using When the test starts to run I notice the pings increasing as shown below. This only happens to Sophos XG. Does not happen to UTM version or any other software. I have tried to disable everything on Sophos XG. No IPS, No Antivirus or Web filtering. Oh this also happens at two different locations. One is Sophos XG installed to HP Server. The other is Sophos XG installed to vmware esxi.
Did you apply the QOS policy on the Rule when you conduct the Speed test . That would mean that the XG would regulate the traffic and other internet traffic would be affected. Would you also provide us the snaps of the following
Not All Broadband Is The Same
Broadband speed and quality varies. Businesses should evaluate their needs carefully looking at employee usage habits and applications riding on the circuit.
Depending on whether you are using your connection for VoIP, video conferencing, or mission-critical applications, you may need a higher quality service. Our Internet quality test does this for you and helps highlight potential risks to your business.
Download Speed
The speed at which your Internet connection transmits data to your computer. This is the largest amount of data you can receive in a specified amount of time. Download speed is measured in Megabits per second (Mbps).
Jitter
To measure the variation over time of latency across the network, you need a jitter test. High jitter values may cause voice packets to be delivered out of order, which can result in echo or talk-over effects.
Why is the location I usually pick missing from the City list?
Before beginning, the speed test tool completes an initial 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.
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.
