Hi NetDuma Team, I have been testing the new firmware for the past few days. Here are my findings: Positive: The new firmware has noticeably improved bufferbloat. This is a clear improvement compared to the previous version. Issues: The router disconnects from the internet randomly every day. Sometimes the connection recovers by itself, but more often I have to reboot the router to restore the connection. At least once a day, I cannot access the router's interface. Both the mobile app and the web interface become inaccessible, and the only solution is to reboot the router. During gameplay, the filtering functions occasionally stop working without any changes being made to the settings. The Geo-Filter and other filtering features appear to become inactive, and again the only way to restore functionality is to reboot the router. Overall, the bufferbloat improvement is very welcome, but the stability issues above make the firmware difficult to use on a daily basis. I hope these issues can be investigated and resolved in a future update. Thank you.

Hello Fraser / NetDuma Team, I would like to report a possible R3 firmware/DumaOS issue. I have spent a long time testing different configurations, and I believe this may not be a normal setup problem. Network setup: Router: NetDuma R3 ISP: Zen Internet FTTP Connection type: PPPoE Speed: 900 Mbps download / 100 Mbps upload Firmware: DumaOS 4.0.540 Main issue: The Congestion Control function appears to have little or no effect. I manually changed the percentages (10%, 20%, 50%, etc.), but the Bufferbloat results do not change. It feels like QoS is not actually applying the limits. I have already tested: IPv6 disabled SmartBOOST ON and OFF Speed Test Bypass ON and OFF Congestion Control mode set to Always Different Congestion Control percentages Different Ethernet cables R3 as main router R3 as secondary router behind Zen router The result is basically the same. Another problem: When running Ping Optimizer, sometimes the R3 loses Internet connection completely. After several reboots it recovers. After recovery, the built-in R3 Speed Test sometimes becomes abnormal: Normally around 900 Mbps download After the issue sometimes only around 500 Mbps download Strange behaviour: Sometimes without changing any settings: Bufferbloat suddenly becomes Grade A Speed Test returns to normal Everything works correctly Then later, without any changes, the problem returns again. Additional observation: When R3 is used as a secondary router, the Speed Test ping was previously around 5–6 ms. After the recent instability, the same setup now shows around 7–8 ms consistently. I mainly use the R3 for competitive gaming (eFootball), so consistent latency and stable QoS performance are very important. Could you please advise: Is this a known PPPoE/QoS issue? Could Congestion Control be failing internally? Is there any Diagnostic Log I can provide? Is there an Early Access/Beta firmware available that I could test? I am happy to test firmware versions and provide feedback if it helps identify the issue. Thank you very much.
