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.
We expect the average reading speed of the file to be within the reading speed limit for the target language/audience. That being said, we understand some instances can be particularly challenging, so we will allow certain subtitle events to go up to 30% over the reading speed limit.
Questions seeking product, service, or learning material recommendations are off-topic because they become outdated quickly and attract opinion-based answers. Instead, describe your situation and the specific problem you're trying to solve. Share your research. Here are a few suggestions on how to properly ask this type of question.
Personally, I use the following services to ping my connection constantly, the first pings a lot more frequently and will give you a graph of the last 24 hours to get an idea of whether your connection has been slow to respond or has stopped working for a short period, which you might not otherwise notice:
The second service just pings every minute or so and will tell you if your connection has been unresponsive, you can set up email alerts to let you know if that happens. In my case I ended up getting rid of Netflix because it was always stalling on my 30Mbps connection. It turned out my connection was dying intermittently, I had to get (on their 3rd visit) engineers from the ISP to replace ends on cables coming in to my property.
If you want to test the throughput of Netflix itself though (if they are using traffic shaping this cannot be tested with normal speed tests as they will not shape your speedtest traffic in the same way as Netflix traffic) you probably want to use something like:
Normally my Internet Speed with Wi-Fi in my room is about 300-400 megabits/s. Somehow, when I watch Netflix on my TV and I do a speedtest on my phone, the speed drops to 50 megabits/s. When I stop the Netflix Stream, the speed immediately goes up to 300-400 megabits/s. (See screenshots).
Why does that happen? It is impossible, that a Netflix stream takes so much Internet Speed. On the Network Monitoring of Duma OS my Samsung TV is only consuming about 0.20 Megabits/s when the Netflix stream loaded. Yet the Speedtest on my phone shows a speed of 50 megabits/s.
That might be. I know, there are no QoS Settings in the ISP Modem, but who knows. I use the ISP Modem in Bridge Mode to connect to the Netgear Nighthawk XR500. So, you think it has nothing to do with my QoS Settings on Duma OS?
Okay so we can rule that out then, that is good. May have just been a weird fluke. No you don't need to reboot to save any changed settings, they will either change instantly or if there is a save/apply button then press that and it will save.
Below, you will also find a video, where I start a speedtest while streaming Netflix. You can see how the speed drops to around 50 megabits/s. In the middle of the speedtest, I pause the stream and you can see how it immediately goes up to around 220 megabits/s.
Well some Devices are offline, the ones that I don't use. But all the devices I use are connected to the XR, especially my Samsung Smart TV, which I use to watch Netflix. On the Network Monitoring tho, I don't see any devices taking the bandwidth away, even when I watch Netflix.
Well I have one ISP Modem and the Netgear XR500 Router. The ISP Modem is connected via a yellow LAN Cable, which was included in the Netgear Nighthawk Box to a LAN Port of the Netgear Router. The ISP Modem works in Bridge mode, so my internet connection comes from my Netgear XR500 Router.
Correct. I just tested again and the issue is still here. In the network monitoring you can see, that no devices are consuming a lot of bandwidth. My Samsung TV is only consuming 0.5 Mbit/s when I am streaming Netflix on it. Yet, when I do a speedtest while streaming Netflix, the internet speed drops from around 300-400 Mbit/s to 50-100 Mbit/s. The moment I pause the stream, the internet speed goes up again.
Then, I reset the network settings on my TV and tried using it without internet connection. Same issue again, the internet connection dropped, even without connecting the Samsung TV to the internet. As soon as I turned off the TV, the internet connection was good again.
I'm feeling like this may be a coincidence regarding when it drops, as you said, not much bandwidth is being used so no need to it to drop. Could you test direct to the ISP modem/router and see if you see the same behavior?
There is no way I can test this at the moment via LAN, because the ISP Modem is in another room than my TV is. I will be able to use LAN ina few weeks. Plus, I get my internet from the Netgear Router and not from my ISP Modem, since the ISP Modem is in bridge mode.
The modem provides internet to the router so if for some reason the modem or the ISP is limiting the speeds during these brief periods then you'll be able to tell by connecting directly to the modem. If you take it out of bridge mode you could try with its' WiFi instead.
I turned my TV on and I did a Speedtest on my iPhone and on my Laptop at the same time. Both devices were in the same room. The iPhone showed a speed of 40 mbits/s. The laptop showed a speed of 300 mbits/s. Both connected to the 5 Ghz Wi-Fi.
Then, I connected my Laptop to a LAN Port of my ISP Modem. On the iPhone I had around 150 megabits/s with Wi-Fi and on the Laptop connected via LAN I had 330 megabits/s. Same result when I connect my Laptop on a LAN Port of the Netgear Router.
Some Netflix users will be able to watch shows at slower and faster speeds. It's a helpful move for blind and deaf users, advocates say. Olivier Douliery/AFP via Getty Images hide caption
It might seem targeted toward people who want to binge as much TV as quickly as possible. But being able to play shows slower (at half speed or three-quarters speed) or faster (at 1.25 or 1.5 speed) is also a boon for blind and deaf viewers.
"Basically, when there is no dialogue between the actors, a narrator comes on and describes what's happening in the scene and what's happening in the show, so we have an understanding," says Everette Bacon, a board member of the National Federation of the Blind.
That's where changing the playback speed becomes relevant. Blind people spend a lot of time listening to speech, such as when using screen reading technology on computers and phones, or with audiobooks.
So much so, that "we have learned and adapted over time to speed that up on a regular basis," Bacon tells NPR's Leila Fadel on All Things Considered. "Because we're listening all the time, and our ears are kind of trained over time to listen at a quicker speed."
Studies have found that some blind people can understand words spoken at much faster rates than sighted people can. And there has been research that shows some blind people can understand speech faster than humans can talk.
It's a similar but opposite situation for people who are deaf or hard of hearing who read a show's closed captioning. Some viewers might prefer to watch at a slower speed to better read the captioning. The option "creates more accessibility, including for deaf and hard of hearing people," National Association of the Deaf CEO Howard A. Rosenblum tells NPR.
Judd Apatow, who directed The 40-Year-Old Virgin and Knocked Up, tweeted, "Distributors don't get to change the way the content is presented." Peyton Reed, who directed Bring It On and Ant-Man, called it a "terrible idea" that "every director I know will fight against." Other Hollywood figures spoke out online, worried that the feature would devalue films and TV and stray from the makers' creative vision.
"There is so much information that they have put out in their content that audio description allows me as a blind individual to comprehend and observe," he says. "And having that speed feature, it just allows me to better understand and better comprehend what they were trying to portray in their creation. I love a lot of Judd Apatow's work, and I think if he understood me as a blind individual and how I consume content, he would applaud this new feature by Netflix."
