The most believable numbers I've found are 1.5Mbps for SD, 3Mbps for DVD quality, 5Mbps for HD quality and 8+ for 1080 on PS3. I don't see Netflix offering official numbers, but playing with Speedtest.net and testing by adding bandwidth eaters like VPN connections until I saw the quality degrade.
While I couldn't find any hard numbers on Netflix's site, it seems the consensus is that as long as you have a decent DSL connection 1.5 Mbs, you should be able to stream successfully (there might be a decent amount of buffering though).Source
I do not personally have Netflix, but my aunt does (the standard definition version through a Wii) and she has no problem watching movies with connection speed that hovers between 700 Kbps and 900 Kbps (tested at Speakeasy.net). I was actually surprised that video playback didn't lag with speeds that low, but there it is.
We have a 1.5/10 Mb connection and see neflix eat as much bandwith as it can get. Not uncommon for it to be using 9mb on HD programs over our xbox 360. However if there is anyother machines online it will kick back to less and change the quality of the stream...
This is Neil Hunt, Chief Product Officer, to tell our members in Canada that starting today, watching movies and TV shows streaming from Netflix will use 2/3 less data on average, with minimal impact to video quality.
I ran the Activity Monitor app on my MacBook Pro while simultaneously streaming Netflix on 4 devices on my home wifi (my MacBook Pro, an iPhone 5, an iPhone 4 and a smart TV upstairs). The total data rate never got higher than 709 kbps (less than 1 Mbps) and on average it stayed around 200-300 kbps. All devices were streaming flawlessly. I even called Comcast on my VOIP phone and the bandwidth usage stayed the same.
To my knowledge, the Activity Monitor shows bandwidth used by the wifi network as a whole (which was what I was interested in), not the individual devices. You see, I am using Comcast "High-speed Internet." How fast is that? They don't say, but apparently I am also getting their Blast service which gives me "up to" 50 Mbps. Wow, right? Except why do I need that kind of speed? Or more to the point: why do I need to PAY for that speed? Or even more to the point: do I ever actually get that speed? I'm not a gamer, though I wonder if I was, would I still need that kind of bandwidth?
I have verified with resources here and can confirm that there are no such similar issues reported. Are you looking for assistance to block Netflix stream in-order to retain bandwidth on the network? Streaming Netflix may cause bandwidth issues but under many conditions such as ISP provided bandwidth is low, stream happens during peak hours when users are in being productive, etc,.
I don't want to block Netflix. My client wants his Netflix to work like it did before we added the SonicWall appliance. The latency just gets really bad. I'm new to Sonicwall and would like to fix his issue but nothing seems to work.
Thanks for providing me some background about the issue. If the bandwidth issue persists only for Netflix stream, could you please check if you have configured any Bandwidth Management on the SonicWall? Please use below KB article as a reference to locate the BWM settings on the SonicWall.
@ChristianSHansen Hello. First, I would suggest opening a support ticket. Second, you could create a new rule just for Netflix and disable DPI or add exclusions for some of the Security Services (GAV comes to mind). Third, you could implement a QoS mechansim. There are many potential items to look at.
Once again, may best to speak with support and get some knowledge transfer as well. BTW, I typically have every TV in the house using a streaming service (Netflix, Prime, u name it,) and I will be on Xbox listening to youtube and sometimes downloading. I have done all this and more on a 570, 670, 2700, 2650, etc. It's just a learning curve sir. Open a support ticket and report back with your solution or ask your local SE to assist as well. - Sincerely, Marco Octavian
Okay, I have not configured any Bandwidth Management. Pinging the SonicWall's LAN interface IP I only lost 1 packet. My client doesn't want to pay for a support contract. We have not licensed any Security Services. We only purchased the TZ270. Where do I go to view the Logs? I think I found the System Logs under the Logs menu found in the Monitor navigation menu. I don't see any errors or anything like that.
I tried that but it didn't seem to help any. Now I cannot connect to the internet even when no video streaming is happening. When I reboot the firewall it allows traffic for about 2 minutes and then it is completely hosed again. As Saravanan suggested I am going to do a factory reset and start over.
You will see a prompt after 4 hours of continuous playback without any user activity. It will ask you to confirm that you are still watching. If no confirmation is received, the channel will exit to the Roku Home screen.
This was a feature that was just added because of so many people complaining about excessive bandwidth usage because the stream didn't auto-stop. It was mostly because people would turn their TV off with the Roku still playing, mistakenly thinking the playback stops if the TV is off. That only happens with a Roku TV, not any players (nor any other brand for that matter).
No, the Roku has no idea it's not feeding an active monitor, so it will continue streaming if you turn the TV off or switch to another input. Yes, it's always advisable to go to the home screen when you're done watching.
But now Netflix has dropped to second place globally behind web-based media streaming apps, as video consumption overall continues to climb, according to the 2019 Global Internet Phenomena Report from Sandvine, a vendor of bandwidth-management systems.
For the first half of 2019, HTTP media streaming represented 12.8% of downstream internet traffic worldwide. Netflix accounted for 12.6% of total downstream volume of traffic across the entire internet, per the report.
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.
