What is Fast.com measuring? Fast.com estimates your current internet download speed. You will generally be able to get this speed from leading internet services, which use globally distributed servers.
Why does Fast.com only report 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.
Why does Fast.com not report on ping, latency, jitter and other things? Fast.com is a simple-to-use way for consumers to test what speed their ISP is providing. It is not a network engineer's analysis and diagnostic speed test suite.
What can I do if I'm not getting the speed I pay for? If results from fast.com and other speed tests often show less speed than you have paid for, you can ask your ISP about the results.
ISP throttling is when your internet provider intentionally slows down your connection. This may happen due to network congestion or your ISP limiting certain types of traffic. A quick WiFi speed test can confirm whether or not your provider is throttling your connection.
Testing your internet speed on multiple devices is the best way to find out how your device and location are affecting performance. If you spend most of your time on one device, test it first, then move on to others. You should also test all devices at roughly the same time and place throughout your testing experience. How much time you spend on each device and wherein the home they are located will affect any results you get.
Fiber internet providers like AT&T, Google Fiber, and Verizon are the best for working from home. You get equally fast upload and download speeds, which are especially great if you need to transfer large files to a remote server or be on video calls.
Our latest customer satisfaction survey puts Xfinity as the best cable internet provider for overall satisfaction. It ranks first in speed, topping rivals like Cox (5th) and Spectrum (7th). Meanwhile, Optimum and Astound Broadband rank in the bottom half of every category.
Video calls require you to send and receive real-time video simultaneously, so there are a few internet speed factors you should keep in mind to get the most out of your remote meetings: download speed, upload speed, and latency.
If you run into issues, your upload speed is the most likely culprit. Cable and DSL internet providers give customers much less upload speed than download. So even if your download speed is safely in the clear for video calls, your upload speed might not be up to par for big group calls. Turn off your video or switch to a wired connection for better results.
The average web page uses about 2MB (megabytes) of data. That translates to 16Mb (megabits) because there are eight bits in one byte. So if you want a whole web page to load within a second, 16Mbps of download speed would be great.
Beyond the speeds you get from your internet provider, older home networking equipment, your network layout, and inefficient connections in your home can also affect your internet speeds. If your internet speed woes stem from something in your network rather than the speeds from your provider, check out our guide to faster internet in your home.
If you have more people working (or learning) from home, you need more speed. For example, a household with one work-from-home parent, a child who is distance learning, and another parent (who does not work from home) might want a 25Mbps or higher plan to make sure everyone can use the internet effectively.
A fast internet speed depends on how much bandwidth you need to do what you want online without interruptions like buffering or slow load times. The FCC classifies anything above 25Mbps as broadband internet, but ISPs offer speeds ranging up to 10,000Mbps (10Gbps).

To test the In-Wall I set up two servers; one server connected to the In-Wall via an ethernet cable, the in-wall connected to an 8port unifi switch, my laptop connected to the 8port switch and I ran iperf3 client on the server and the iperf3 server on my laptop. That gave me a consistent 940Mb/s. I then installed iperf3 on my synology NAS which is also connected to the 8port unifi switch and again I got 940Mb/s. So the problem does not appear to be the In-Wall or the 8 port switch. I then checked my USG and found that iperf3 was installed on it. I ran iperf3 as the server on the USG and client on my laptop but got less than 300Mb/s. Swapping client and server did not help. I also connected my laptop directly to my ATT gateway and did the ATT speedtest and got the same slow speeds that I was getting when doing the internet speed test through the unifi in-wall AP which seems to imply that I have an ATT problem.
Speed test websites and speed test apps are tools that enable individuals or IT professionals to test the speed of an internet connection on any device. Speed tests can measure upload speed, download speed, ping, latency, jitter, and more. Speed test websites can be used to test the internet speed of a WiFi or ethernet connection from a web browser on a desktop or laptop, while speed test apps can be downloaded natively to smartphones so that the wireless connection can be tested from the mobile device.Compare the best Speed Test websites currently available using the table below.
Speed Test GuideSpeed test websites and apps are tools used to measure the download speeds, upload speeds, and latency of a particular internet connection. These tests can help diagnose issues with a user's internet connection and determine whether their network is performing optimally.
The most basic speed tests begin by measuring download and upload speeds in megabits per second (Mbps). The higher the Mbps number, the faster the connection. Download speed is measured by sending a large file from the test server to your computer or device while upload speed measures how quickly you can send data from your device back to the server. Generally speaking, lower latency will result in better performance when using applications such as video conferencing or online gaming.
Speed test websites and apps vary in cost depending on the features offered. Generally, most of these services are free and available to anyone with access to the internet. However, some speed test websites and apps may offer paid plans with additional features such as detailed network diagnostics or monitoring of your speed over a period of time. Usually, these packages range from around $5-$30 per month, although some may charge a one-time fee for a yearly subscription. Paid plans often provide more accurate results than free versions due to their powerful software and servers that are specifically designed for testing internet speeds accurately.
There are four ways you can connect the internet to a Raspberry Pi board. You can use a built-in WiFi, add a WiFi dongle, use an Ethernet socket, or add one via USB. The Raspberry Pi network speed test covers the following boards:
Each board is tested with the same (latest at the time of writing Raspbian Pixel image) class 10 microSD card, the same power supply is used in all cases (an original adapter for indoor tests, and the battery bank for the range tests). I have used Tasker to automate the iperf test, you can read about it here.
The wireless performance tests have been done at 1m, 5m (through walls), 10m, and 20m. As the board and adapter orientation do matter, I tried to orient the board and the adapter in a way that would allow for the best internet speeds. The orientation of the adapter has been consistent across the tests. This should cover the test environment setup, but feel free to ask me any questions about it.
You may ask why test the Raspberry PI 2 and 3 if they already have the LAN socket? I hope the chart below will answer your questions: We see a very similar performance from the Zero family, with the minimum speed of 56Mbits/s to 111Mbits/s on Zero W and 70Mbits/s to 108Mbits/s on Zero. Both boards seem capable of the same performance and the average connection speed is high. The Raspberry Pi 2 and Raspberry Pi 3 shows, however big differences in speed. The increased speed over USB over the Zero family has to come with better processing power. I have to assume the CPU on Zeros are the bottleneck.
Another thing to consider is the orientation of the board. While with Raspberry Pi 2 and 3 orientations was not making much of a difference, the Zero W performs much better when the upside is directed towards the router. The same applies to my USB WIFI adapter that prefers to point its bottom towards router for the best speeds.
Another baseline test. The device is oriented in the optimal position and placed about 1m away from the router. There are no obstacles, the line of sight is maintained. This is a baseline test to show us what we should expect from the built-in interfaces:
The Raspberry Pi 3 and 2 share the same performance with consistent speeds, min 69.7Mbits/s and, max 81.8Mbits/s and the Raspberry Pi 2 is just behind with 75Mbits/s low and 82.8Mbits/s high. A good baseline to see how the range test plays out.
