LinuxDan Posted March 5, 2022 Share Posted March 5, 2022 Every day the netduma R2 which i have updated to 3.0.394 is dropping speeds SIGNIFICANTLY from 540mbps download to 10mbps download, 70 upload to 7 upload. I've checked drivers, ethernet to modem, Ethernet from modem to router, to wall and all is fine. To fix this i always have to go to dumaos/ and restart the router which to be honest is fairly quick (2 mins or so) however that disconnects EVERYBODY in my house without them knowing and them being kicked out of games whether they are playing competitive matches or casual etc. I'm not sure if this is the result of the DHCP lease which i changed to the recommend time of 168 hours to avoid being kicked off the internet every day or so initiating further issues that cause internet dropout. However DHCP is always before these errors it seems, so i'm not sure if they're triggered when someone joins the network or random errors that do happened every day. QoS is off, tried with it enabled too and nothing - not a bandwidth issue, r2 is not overheating, r2's RAM has free capacity left. This error i get is this listed below in the attached .txt file. However, the error seems to change often i believe. I labelled the mac addresses as 'Mac' and (yes i know private IPs) as '(IP)' Please help me as this is a daily occurrence and a massive pain up my ass. Cheers. log-1646510367573.txt Link to comment Share on other sites More sharing options...
Administrators Netduma Fraser Posted March 5, 2022 Administrators Share Posted March 5, 2022 Hey, welcome to the forum! I can't think DHCP would have anything to do with speeds as it just hands out IPs. Where are you testing the speeds and around what time of day e.g. does it always get reduced during peak times? Have you waited to see if speeds are restored on its own without a reboot? Link to comment Share on other sites More sharing options...
LinuxDan Posted March 5, 2022 Author Share Posted March 5, 2022 Hey fraser, thank you for the speedy response. This seems to be random and not in any peak times, it can be at 12 am, 2am, 12pm you name it—it just happens once every day. If i wait approximately 6 to 7 hours it manages to fix itself, looking at the log it looks like the router attempts to start a process and hits a wall/error and retries only to do the same thing which must bunk up the internet speed. I found that to be a case with somebody who was programming things on stack overflow and they received the same error (although not on the r2 or any routers) but their speeds were slow. Also found another user on this (netdumas) forum with the same issue. Speeds in peak times are surprisingly not effected, i pay for 500 but get given 540mbps down as an overhead or some sorts i suppose. I've tested with my phone next to the R2 (5 foot away) and got worse speeds than ethernet since wireless, got 5mbps down and 4 up, ethernet on my PC is 10-14mbps down and 7 up when i've tested before wireless and wired when i was giddy i got quicker speeds and can confirm they were consistent until these issues started appearing which slowed down my internet at the random period during the day this happened until i waited 7-8 hours for it to solve itself. Issue only gets solved in a reboot for a few hours until the next day however the log is still saying the same with trying to use/start a process and failing on repeat after the reboot. Also tested with the built-in Rapp, Connection benchmark and did hit my speeds however, when this issue occurs it also tells the same as my wired connection, 10-14mbps down, 7 up.

Administrators Netduma Fraser Posted March 6, 2022 Administrators Share Posted March 6, 2022 You're welcome, thank you for the detailed information, so you said it was all working fine before it wasn't, do you recall if you changed any settings specifically prior to the issue appearing? When the issue occurs, if you test the speed on the modem do you get the expected speeds? Also when it happens how many devices are using the internet on average and what kind of things are they doing e.g. downloading, streaming etc? Basically I want to know if it seems to happen during heavy bandwidth usage. Link to comment Share on other sites More sharing options...
LinuxDan Posted March 6, 2022 Author Share Posted March 6, 2022 I haven't changed any setting except DHCP lease time to 168 overall. When tested, my original box seems to have the correct speeds and no issues, when i test on the R2 it is also fine and expected speeds except when this issue occurs, speeds drop significantly. I have 2 phones connected, 1 pc & 1 console in this household connected to the R2, console via ethernet & PC via ethernet used by various people. On the PC is usually me watching youtube or playing a game (usually watching youtube), my phone is connected but inactive, the other phone i believe is inactive but connected, the console is playing games & in a party chat. 100Mbps could easily handle this and 1440p video playback and be fine, 540down and 70 up shouldn't have a problem and isn't a problem until this issue occurs. If there is a Rapp i can use to monitor bandwidth i can analyse the traffic over the next day and tell you but that'd take some time. Bandwidth usage may be plausible however i have not looked into that fully so i couldn't tell you. Sorry for the late 2am response, very tired! Thank you for the support so far fraser.

LinuxDan Posted March 11, 2022 Author Share Posted March 11, 2022 After monitoring my internet, there seems to be a lot less issues if none. I've been monitoring very closely, after this PM the issue seems to be solved? from what i've experienced so forth. Link to comment Share on other sites More sharing options...

LinuxDan Posted March 31, 2022 Author Share Posted March 31, 2022 Hello, i'm back. This issue occurred again and is either different - same problem or same issue - recognised the cause. The Duma R2's was only receiving 90mbps download out of the 570 i pay for, 30 up out of the 60/70 or so i pay for by doing a speed test in the DumaOS interface. I thought it may be the ISP or modem or even the ethernet cable between the two router & modem. What i do is check the cables, they're all connected perfectly, no play. So i factory reset the router via the DumaOS interface and suddenly get my speeds back at roughly what they are which is good enough. So what caused this? well, it's 12am and only 2 people are home, me and another person - of which they are sleeping. The only traffic is my doorbell cam which uses less that 30kb/s constantly and my pc/phone. My phone uses 500kbps or less when idle, my pc uses about 50-90mbps on average watching youtube videos and doing other web browsing, this is where the problems arise... everyone complains the wifi is slow of which i frequently experience, if my pc on average is using 50 mbps when browsing & watching youtube and about 90mbps when downloading (since when this issue occurs the router only receives 96mbps) then other people have no bandwidth and when they try to use the internet and when i even try to download on my pc of which downloads completely stop, throttled, youtube buffering etc you get the gist then it's even worse for them. The speeds go down to 96mbps down and 30 up and the problem is ONLY fixed by factory resetting which lasts about 1 - 4 days before it starts doing it again. After factory resetting today i noticed all 4 CPU cores of the R2 are sat at 100% and are completely and figuratively "redlining" 24/7 at 100% usage despite nobody using the internet and when people wake up in my household and want to use it that when the problems arise, even at night when nobody but me is using it, i still experience major problems. I think it's because the cpu gets too hot and throttles internet somehow or is 100% on all 4 cores on running a program that it can't handle all the bandwidth which would explain why i only get 96mbps and not 570mbps and that it must last at 100% for 1 - 4 days before it gets hot or starts to throttle again and i have to factory reset.

Netduma Liam Posted April 1, 2022 Share Posted April 1, 2022 When the issue is occuring and the R2 is at 100% CPU usage, could you please do the following: Got to three-dot menu in the top right, then click advanced and Rapp Performance. Click the advanced tab Hover your mouse just slightly above the 'Rapp' column and you should see a check box appear titled 'Show Kernel Values' Click this and send over a screenshot of the full page. Hopefully this will give us some more insight as to what's going on. Link to comment Share on other sites More sharing options...
LinuxDan Posted April 1, 2022 Author Share Posted April 1, 2022 attached i have included a .txt file by clicking the copy button on the rapp performance "page" as seen below and pasting them into a .txt file. Hope this helps. Thank you for the reponse. DumaRapp.txt Link to comment Share on other sites More sharing options...
LinuxDan Posted April 1, 2022 Author Share Posted April 1, 2022 Also, i just rebooted the router and whenever i attempt to visit dumaos/ on my phone, pc i'm prompted with the log-in page, however, i enter the correct credentials and it just pops up with the log-in prompt again?

Netduma Liam Posted April 1, 2022 Share Posted April 1, 2022 OK, annoyingly there isn't really anything out of place in the screenshot you've sent. Could you perhaps download a full copy of the log file when the issue is occurring so I can pass it over to a developer to look at? Perhaps try logging into the interface via an incognito browser, see if that helps. Link to comment Share on other sites More sharing options...
LinuxDan Posted April 1, 2022 Author Share Posted April 1, 2022 I will send a new reply with the log file when the issue occurs. Strangely or coincidentally, the R2 is now sat at normal cpu usage as shown below when after a reboot from the interface and from the plug socket downstairs it had this issue & even occurred when i pressed factory reset in the interface on every factory reset it would still have the same issue... until a few minutes ago when i went to the physical R2 itself and put a pin in the reset hole and now as pictured below the usage is what i'd consider normal. If this issue happens again i'll attach a log file below. Link to comment Share on other sites More sharing options...
Administrators Netduma Fraser Posted April 1, 2022 Administrators Share Posted April 1, 2022 Great thank you, it's worth using Congestion Control set to Always and 70% to see if that prevents the issue happening given it seems to happen when there isn't much bandwidth to spare Link to comment Share on other sites More sharing options...
LinuxDan Posted April 1, 2022 Author Share Posted April 1, 2022 Will do, this is a weird issue. Maybe it is bandwidth since when there's people here it's 100 all 4 cores but wouldn't explain it when nobody was online at 12 last night or in the past 6 hours and it still had this issue on every factory reset until i went to the physical box itself and reset. Very odd, i'll keep you posted. Netduma Fraser 1 Link to comment Share on other sites More sharing options...
LinuxDan Posted April 1, 2022 Author Share Posted April 1, 2022 I caught the issue, got the log file attached below. It seems to have possibly fixed itself but it disconnected everyone in the house, "connected but no internet". CPU usage skyrocketed when this happened & the dumaOS interface kicked me out. Also CPU usage after this incident is now throttled at 100% all cores. Also, see attached of the aftermath of this incident in full labelled "NEWlog". Seems to be throttled at 100% while searching for HTB: quantum of class 10001 is big. Consider r2q change. daemon.err cli.lua[8803]: RTNETLINK answers: No such file or directory Another edit; Some rapps are also not loading now, like network monitor, some rapps say "uncaught exception: undefined" when attempting to load them such as geo-filter map etcNEWlog-1648852011085.txt log-1648851656104.txt Link to comment Share on other sites More sharing options...
Administrators Netduma Fraser Posted April 1, 2022 Administrators Share Posted April 1, 2022 Ahh that's brilliant, the log definitely contains a lot of entries that are not usually present, I will pass this on to a developer who will be better able to make sense of it and hopefully decipher the issue.
