Smoggie21 Posted March 29, 2016 Share Posted March 29, 2016 Hi Guys have just bought a Netduma R1 and im really pleased. However i pay for 200/12 with Virgin media and since installing the Netduma R1 my download speed is consistantly around 100-110 but my upload is what i expect 12. I can not manually DMZ as once the Virgin Super Hub 2ac is in modem mode the advanced settings are not available I have followed the optimal settings guide and tried different ethernet cables but same results. I do have an open nat type 2 on my PS4. Do you have any suggestions to resolve this issue. + Thanks Link to comment Share on other sites More sharing options...

sidestep6 Posted April 1, 2016 Share Posted April 1, 2016 at least you still get 100, occasionally the router's congestion control bugs out for some reason and turns what is normally 60/5 connection to 5-6/5. the upload stays normal but the down gets cut significantly and this is with zero settings changed. only way to get it to go back to normal is lower the congestion control, save and then set it back to where ever it was set prior. fyi this was something I experienced with firmware 1.03.4 and it is still present in 1.03.6. oh and it wasn't the connection itself or third party software interference this happened at more than one location and I couldn't identify a cause only the results after it happened, could be a bug in the preemptive algorithm.

Administrators Netduma Fraser Posted April 1, 2016 Administrators Share Posted April 1, 2016 You should be using the reactive algorithm if you have speeds over 60mbps that's probably where you're going wrong Link to comment Share on other sites More sharing options...
sidestep6 Posted April 2, 2016 Share Posted April 2, 2016 You should be using the reactive algorithm if you have speeds over 60mbps that's probably where you're going wrong 60-5 is what my isp currently offers, so that is what I'm running. I don't have a problem with some of it being cut off from the congestion control but when it drops all the way down to 5-6 down like as though it's applying the upload bandwidth cap to the download it gets bad because simple activities like watching amazon prime becomes difficult. again it's probably a bug related to congestion control and preemptive, I've experienced it way to many times and from two separate locations for it to be related to the connection to the isp itself and I can manual fix it by adjusting the download cap in congestion control - saving it - then setting it back to where it was and saving it again. then its back to normal.

Administrators Netduma Fraser Posted April 4, 2016 Administrators Share Posted April 4, 2016 Try the following: 100% anti-flood Reactive algorithm Share excess enabled Reset device prioritisation & apply IPv6 off in WAN, LAN and misc settings Deep packet off in misc settings Ensure Cat5e at least cable from PC to duma and do a speed test. Try it on different servers around you to rule out any overloaded servers. If you still fail to get your speeds enable turbo mode in misc settings as well. Should keep your speeds after that.

Try it on different servers around you to rule out any overloaded servers. If you still fail to get your speeds enable turbo mode in misc settings as well. Should keep your speeds after that. I'll try to explain it again because it's not the full speeds I'm concerned about getting, it's the normal speeds when the router is configured that I'm interested in keeping. example: the 60-5 configuration setup in the router with 95% congestion control on up and down gets me around 37-4.2 in the speedtest I use, those speeds aren't a problem because I don't need more than that and the connection stability is more important which the router is helping with. The problem is sometimes the router somehow messes up and kills the download bandwidth, all on its own without any settings being changed. It will go from 37-4.2 to around 5-4.2. So the upload is never changed or affected but the download gets cut down to basically what I have the upload set to in bandwidth control. which is why I said it's like the router trips up and sets the bandwidth in the configuration to 5-5 instead of 60-5 or the congestion control sees it as that because the only way to get it to fix itself is to raise or move the congestion control for download to anything other than what it is currently set at. So in this case if I changed it to 94% because it was set to 95% it would wake up or reset itself and go back to around 37 down. After that I can set it back to 95% again or whatever it was set to before 100% or 70% and it will go back to doing what it normally was before. That was the only way I could get it to fix itself and I don't recall that resetting the router had any affect which is why I found it to be a bug related to congestion control. This issue was present in 1.03.4 and it is still present in 1.03.6, I really don't want it to carry over into the congestion control + anti-jitter etc. algorithm. It would be a bummer if this was a preemptive algorithm bug because I thought that one was better than the reactive one and I thought it was why my connection was so stable with very little packet loss.
