Thanks, could you remove your SmartBOOST priorities please and see if it continues? Other than what you've mentioned so far, what settings have you changed from their defaults?

Already added them. Around 20:18 it happend

What timestamp did it happen around? In Settings > DHCP > Add Rules > Select Device > Save. Do that each wired device you're noticing the disconnects/issues with. Then reboot the router from the interface, wait 4 minutes and see if it happens again please.

Hi Fraser, unfortunately it did not fix the problem. Ethernet still went out. Wifi still works. Here are the logs minutes after it happend R3_2026-04-21T19_20_14.978Z_logs.txt

of course! i even resynced it too just to be sure

I'll chase them, thanks for letting me know it's still happening

that dublin server is one of their authentication servers.. Call of Duty authentication servers verify player credentials, usually during initial launch, through Activision’s backend

any update on this? still showing the same thing.

I've given you Early Access where we've recently released a fairly large bug fix/QOL update that may help. https://forum.netduma.com/topic/60946-new-r3-firmware-dumaos-401147/ Upgrade to that and then if you still get the issue please get the logs when the issue next happens, before rebooting and we can take a look.

Very bizarre! Perhaps their servers were under heavy load at the time. Thanks for the update!

You shouldn't need to specifically port forward but if you look up the specific games you're playing you can find their specific ports to add

Hi Netduma Support, I’m experiencing an issue with my Netduma R3 where the Ethernet ports stop working after about 1–2 days of uptime. Here is what happens: The router works normally at first After 1–2 days, all devices connected via Ethernet lose internet access WiFi continues to work without any issues A reboot temporarily fixes the problem, but it comes back again after some time I have already tried the following troubleshooting steps: Updated to the latest firmware version Performed a full factory reset (without restoring any backup) Set up the router from scratch Tested multiple Ethernet ports Tested different Ethernet cables and devices Disabled IPv6 Increased the DHCP lease time to 10000 The issue still persists consistently. From what I can tell, it seems like either a DHCP issue or a software-related problem, since a reboot always restores functionality temporarily. Could you please advise on what might be causing this and if there is a fix or known issue? Thanks in advance.

Here are my results today — 10:47 AM, April 21, 2026. And the next day it looks like this… everything is kinda weird.

Yeah, Fraser, you were probably right. I checked this morning and everything’s fine. Yesterday it was messed up, now it’s normal. That site is just buggy as hell — screw that site.

What port other than 3075 fo pc/Xbox Game pass should i have?

They shot first. I still won the fight. Playing on East Coast servers from the West… still outgunning like this. 🎥 Watch it here 👉 https://youtube.com/shorts/2FnZuO-Lm3Y?si=-S97OeHoOpgN90VF — 🔗 All Platforms, Links, & Setup: https://toddzillainla.carrd.co/ 💬 Discord: http://discord.gg/zillagaming (if link is dead, add me @toddzillainla and I’ll send you an invite) Or watch here 👇 Thanks for watching! 🙏🎥❤️✨

If speedtest.net is showing your normal speeds then the router isn't limiting you but try toggling speed test bypass in Ping Optimizer > Advanced. Otherwise it's unlikely there is any feature impacting it and is more likely the site.

Hi, I’m experiencing a strange issue with my NetDuma R3 and wanted to check if others have the same problem. When I run a normal speed test (e.g. Ookla Speedtest), I get my full speed: Download: ~220 Mbps Upload: ~40 Mbps However, when I run the Waveform Bufferbloat Test: Upload looks normal BUT download drops massively to around 10 Mbps This is a huge difference (more than 20x lower than expected).

You can't individually filter a cluster of servers within one location per se but you could add the 17ms ping server to your deny list so you don't play on it again. Do be warned though that denying lots of servers will leave you with very few options for servers to play on and may increase search times/prevent you getting a game altogether.

Are you just focusing on the jitter result on the bufferbloat test or are you actually experiencing that in game also?

Hello! I was able to get my geo fence working and pining exact cities etc. I am now wondering how I can ping the best “server” in that city. For example I saw a Chicago server on 6 ping but connected to a different Chicago server with 17 ping. Is there a way to get only that 6 ping server?

if I connect the other router I have A+ without problems

So the fiber router connected to the R3? For the Geo-Filter you're covering a huge area so you could be getting servers that are a way higher ping, reduce it so you're covering just the closest server to you. Just on SmartBOOST, add Gaming as the activity, then switch to device on SmartBOOST and select your device.

No, I don’t have other devices heavily using the internet. My setup is: I have a fiber modem connected to the Netduma R3 using PPPoE. The R3 is used only for my PC. As for the main fiber router, it only has two iPhones connected to it. My internet speed is 300 Mbps download and 100 Mbps upload. Regarding the Geo-Filter, since I’m located in Saudi Arabia, the closest server I get is around 20 ms ping. I have enabled Steady Ping and set it up in a simple way like shown in the screenshot. About Congestion Control, I understand that having it at 100% doesn’t help. I will try setting it to 75% download and 68% upload and see how it performs. I have already removed the 40 Mbps bandwidth allocation after writing this post, as I’m trying to fully utilize the R3 in the best way possible. Regarding these two points, I haven’t set them up before, so I would appreciate it if you could explain how to do them, preferably with screenshots: Enabling “Prioritize Gaming” globally (so it covers all games) Prioritizing my PC as a device as a backup

It should be easier to filter BF6 on the new R3 Early Access firmware now
