Codeman Posted October 3, 2016 Share Posted October 3, 2016 I have a Roku devices that I was watching Amazon Prime on and suddenly the video just froze. I checked the Network Monitor and apparently my computer was running an update and was using all the bandwidth despite the Download Prioritisation for the Roku being set to 75%. I was able to get it working by unchecking Share Excess or by adding the Roku to Hyper-Traffic but this is not a good solution for me as it will interfere with other devices on my network. My guess is that the Amazon Prime video is actually decreasing it's bandwidth usage in an attempt to keep the video playing while other things are using the internet causing havoc with the Device Prioritization and making it think that the Roku needs less bandwidth so it is sharing the excess until the Roku has no more to use. Any way you can make your Device Prioritisation a little more aggressive so that video streaming services will get the bandwidth allotted to them and not think they are being starved of bandwidth forcing them to use less?

Slipknot31286sic6 Posted October 3, 2016 Share Posted October 3, 2016 U cant put Roku in hyperlane that's only for gaming. You'll jack up the router and network doing this. It's for low latency. Roku shouldn't lag when Windows is doing an update. Unless u set router up wrong which sounds like you did. I run 3 kodi and game on ps4 no lag with pc downloading as well... What's ur up n download?

Administrators Netduma Fraser Posted October 4, 2016 Administrators Share Posted October 4, 2016 Don't put it in hyper as above. Are ALL devices connected to the R1? If there any devices connected via wifi or ethernet to the hub this will mean CC will not work effectively. Are you using anti-flood at 70/70? As that would prevent any other devices causing lag/buffering. Link to comment Share on other sites More sharing options...
Codeman Posted October 4, 2016 Author Share Posted October 4, 2016 I am well aware what Hyper-Traffic is for and how it can affect my network which is why I stated it was not a good solution but it was one of the 2 ways I found to get it working at the time. My setup is as follows: modem plugged into Netduma, access point plugged into Netduma, and Roku connected to the AP. And yes, it is purely an AP and not a router. All devices showed up on device manager during the time this happened and network monitor was accurately showing bandwidth for the specific devices (Roku and computer). The Netduma was just giving up bandwidth that was allocated to the Roku for the update running on the computer unless I unchecked share excess. I cannot afford to move the sliders to 70% as that takes off to much bandwidth and I wouldn't be able to play the video anyway. I am using anti-flood at 99/100. 99% download because Hyper-Traffic won't even work for me unless the slider is moved. I have been able to get things working fine with the qos in dd-wrt on my previous router but would like to stick with Netduma if possible. Link to comment Share on other sites More sharing options...
Administrators Netduma Fraser Posted October 5, 2016 Administrators Share Posted October 5, 2016 What are your speeds? You should still be able to play the video no problem and use anti-flood at that level. If your speeds are slower you can switch to reactive algo so that more speed is preserved but you still benefit from 70/70 Link to comment Share on other sites More sharing options...
Codeman Posted October 5, 2016 Author Share Posted October 5, 2016 I was actually already using reactive for that reason. I have 3.01Mbps down and .49 up. I know it's not much but Netflix, Amazon video streaming, and online games still work great and it's the fastest I can get. I really don't think video steaming would work well at 70% and it would definitely hamper BitTorrent downloads. I'm perfectly happy with everything so far; I just don't know why the device prioritisation didn't work with my Amazon video streaming. My only guess is that the device prioritisation was not aggressive enough at reserving the bandwidth because if you understand how video streaming works it makes sense. When your internet bandwidth decreases the video quality is decreased to use less which eliminates buffering and when your bandwidth increases again the quality improves but in my case the computer update somehow took all the bandwidth causing the video to buffer. What other explanation could there be if device prioritisation worked after unchecking share excess? I say device prioritisation is to blame and I'm hoping it'll get sorted out in future updates.

Administrators Netduma Fraser Posted October 6, 2016 Administrators Share Posted October 6, 2016 Does that mean you've been leaving anti-flood at 100%? That will definitely enable devices to saturate your connection. I would definitely at least try having share excess on, reset device prio and 70/70 anti-flood and see how you get on with it. We can then go from there. Have multicast snooping enabled in miscellaneous settings Link to comment Share on other sites More sharing options...
Codeman Posted October 6, 2016 Author Share Posted October 6, 2016 I feel like you aren't understanding what happened so I will try one more time. My problem was that device prioritisation did not work for my streaming video player (Roku). I had anti-flood set to 99% download with reactive because I do not have much bandwidth to spare and because hyper-traffic will not work properly with my ps4 unless the slider is moved at least 1%. I left the upload at 100% because I have never saturated it. I set the Roku to 75% on the download section of device prioritisation to reserve at least 75% of my download bandwidth for it. I had share excess checked. I was watching a video and suddenly it started buffering constantly so I looked at the network monitor and saw that my computer was now using all the bandwidth despite the fact that the Roku should have had 75% of my download bandwidth allocated to it. I decided to try unchecking share excess and suddenly the video was able to play again because it was now getting it's 75%. My problem is that device prioritisation did not work as it should have with share excess checked and I cannot simply leave share excess unchecked as that does not leave enough bandwidth for my other devices. I do not understand how changing my settings will suddenly fix this glitch/flaw. Perhaps you can explain to me how capping my bandwidth at 70% of my 3.01Mbps via anti-flood is going to magically make device prioritisation work.

Administrators Netduma Fraser Posted October 6, 2016 Administrators Share Posted October 6, 2016 If your PC was suddenly using a lot of bandwidth and so were other devices and your roku was not using much then share excess enabled those devices to utilise bandwidth. The roku will only take up to 75% if it definitely needs it, otherwise the excess will be shared to other devices. Thats why when unticking share excess, other devices were capped and roku can use as much or as little of 75% as possible. By anti-flood not being set low enough the PC was able to cause your other devices to lag. Anti-flood prevents any devices causing any other to lag. Though you only have low speeds it still should prevent this happening. I would at least give my advice a go and see how you find it. Then if it's still an issue we can go from there.

Codeman Posted October 6, 2016 Author Share Posted October 6, 2016 But my issue is not lag. It is bandwidth for the Roku. It did need the bandwidth that was allocated to it. To start with the Roku was using 100% of the bandwidth and once the computer started to update it took all the bandwidth even though the Roku was supposed to get at least 75% via device prioritisation. The device prioritisation did not reserve what it was set to reserve for the Roku. I understand how the share excess works but in this case the update on the computer was taking more than the excess. It took it all. I'm sure most people, with high internet bandwidth being the norm, will never notice if this happens to them but as I said before my guess is that Netduma's device prioritisation, with share excess checked, is simply not fully compatible with video streaming that can auto adjust it's video quality based on available bandwidth. It would be nice to get acknowledgement of this issue so that perhaps it can be fixed as Roku is a very popular streaming device. Link to comment Share on other sites More sharing options...
Netduma Staff Netduma Jack Posted October 7, 2016 Netduma Staff Share Posted October 7, 2016 We understand your issue, but could you try Frasers suggestion? Anti-flood doesn't simply limit your bandwidth usage to that amount; it allows devices to get the best connection depending on how it's set. Setting it so high could very likely be causing this problem. If this doesn't work, Fraser would be happy to do a 1 on 1 with you. Link to comment Share on other sites More sharing options...
Codeman Posted October 7, 2016 Author Share Posted October 7, 2016 Maybe you could be more technical in your responses as my networking knowledge is somewhat more advanced than average. Are we basically talking about how QoS works here in that you have to limit the the bandwidth to a certain level in order to manipulate the traffic? Are you saying that in order for the device prioritisation to work I have to set anti-flood to 70% so that the Netduma can effectively manage the bandwidth? If you are it would be nice if that was said in the FAQ or something and I wouldn't have had to create this thread. All I know is that you say on your website that this is different than QoS. I feel the lack of technical info on the way this product works may be the cause of my frustration. Link to comment Share on other sites More sharing options...
Administrators Netduma Fraser Posted October 10, 2016 Administrators Share Posted October 10, 2016 In a sense yes, it doesn't limit it in the sense that it prevents any devices from using the internet as normal. That's why I suggest it because I don't believe it will prevent you streaming. No that isn't the case, my suggestion is to leave device prioritisation all equal w/ share excess on and allow the anti-flood to do it's work. Again if you try my suggestions and it doesn't work then thats fine and we can go from there but I'm confident that will resolve the issue you're having.

Codeman Posted October 11, 2016 Author Share Posted October 11, 2016 I've since sent back the Netduma but thanks anyway. All I wanted was for it to provide my Roku the 75% download that I allotted to it with device prioritisation. It just doesn't make sense to me how your suggestions are going to do this i.e. bringing anti-flood down to 70% which will not even allow me enough bandwidth left on my internet to stream videos on my Roku at all, and resetting the device prioritisation so everything has an equal share because my computer had already stole all the bandwidth despite the Roku being allotted 75% so I fail to see how making my devices to fight over the the available bandwidth is going to get my Roku the 75% it needs. I probably would've kept the Netduma if it weren't for these suggestions that would undoubtedly cause more problems on my network than it would help. I'll revisit using Netduma once it matures a bit and maybe I'll be able to do what I want then. And FYI the wifi on your router causes static on my wireless headset running on 2.4GHz and yes I've tried different channels. It's the Netduma as my Netgear wifi does not cause any static.

Administrators Netduma Fraser Posted October 11, 2016 Administrators Share Posted October 11, 2016 Sorry to hear that. I believe the issue would have been resolved with my suggestion, it was at least worth a try. Perhaps when DumaOS is launched you will reconsider us again. I will now close this thread.
