What happened? When will the Istanbul server be added?

Thank you for the quick reply. I have screenshotted the system logs I believe you were asking for. This is all that it contains despite numerous QoS changes. The modem the XR1000 is connected to is a Spectrum-issued Ubee EU2251. It doesn't have it's own router functions. The speeds seen in Connection Benchmark and third party speed tests show completely erratic low speeds. At 80% CC with 940mbps download and 40mbps upload, it should be 752mbps download and 32mbps upload respectively. It is all over the place in the low multi-hundreds for download and low teens for upload. Previously, if CC acted erratically, I could fix it by reboot or power cycle. Currently, I am able to replicate an all device connection drop just by unchecking "Disable QoS" and again by enabling "Always" in CC. After these changes, the connection will eventually return, but the frequency of further random drops increases. This has never happened before on any previous firmware. All devices hold an active connection to the router. Device Manager has no ghost devices or offline devices. Even when a device was offline in the Device Manager page, QoS has never behaved like this on the previous firmware. Forgive me for any misinterpretation. I have never had an issue of this scale in the 2-3 years I have owned this router.

That's just security fixes so I'm surprised it's had such a profound effect for you as they/we haven't touched DumaOS in that update. Please provide the logs when they next disconnect. What are the speeds you're getting with them set to 80%? What is the model of the modem/router the R3 is connected to and how have you set that to ensure all traffic flows to the R3? E.g R3 in its DMZ, modem/bridge mode. Are ALL devices connected to the R3? 80% may have worked on the previous version but different versions may require different percentages so it's worth testing/fine tuning to find what works better. The first upgrade attempt wouldn't have caused persistent unclearable issues.

What ping are you getting to the Texas servers then? Try different areas, don't just stick with the one area, experimentation is key

Great to hear that, yes it would have been - you won't have seen it around on the forum too much as our general advice and especially in this instance would have been to factory reset after upgrading as it's a big jump forward

Let us know how you get on!

Understood! Let us know how you get on after some fine tuning

There is Internet Rules in Settings which for the moment is as much Parental Controls as we have/are working on

My XR1000v1 router has been updated to firmware version 1.0.3.88_2.1.43 from firmware version 1.0.0.74. Since this update, the first major issue I have expirenced is all devices both randomly and predictably dropping connections over ethernet and wifi at the same time before regaining internet connection. My Galaxy A15 will specifically say "connected without internet." All LED light indicators on the router show solid white with no error lights on the EU2251 Modem. I'm not on fiber or pppoe as my ISP is Spectrum. I have power cycled the modem before the router. All devices have been address reserved with no randomized mac addresses. All IPs and MACs appear to match in the Address Reservation page and Device Manager page with no ghost devices present. The second major issue, is that once QoS has been enabled (unchecking "Disable QoS" in the three line menu) all connections immediately drop briefly. Setting Congestion Control to 'Always' also causes it to behave erratically with speeds falling far below set slider percentages also with potential connection drops. Packet loss, abnornally high ping values flollow. The Connection Benchmark, Xbox speed test, Ookla speed test all show similar results tested with an ethernet connection to an Xbox Series X. When this issue is present, it has been confirmed to me by multiple others in an Xbox live party that my voice becomes broken/laggy. I don't believe this issue is a visual bug. Setting Congestion Control to 'Never' does not fix the issue. Disabling QoS entirely does sometimes fix the issue, but once re-enabled by unchecking the "Disable QoS" box, the issue immdiately returns with all symptoms including an immediate brief connection drop to all devices. Line speed is 1gb download, 40mbps upload. Input speed is 940mbps download, 40mbps upload. This speed input was used without issue on the previous firmware version. Sliders are set to 80% download and upload. These sliders worked fine on the previous firmware version. When updating the XR1000, I did so over a wired connection using the browser UI on Edge. When the first attempt to update was initiated through the update page, it initially failed. I was able to re-access the page, and attempt a second time. This attempt succeeded. Four factory resets (three pinhole and one erase) after the update has not cleared these persistent issues, along with multiple power cycles and UI reboots. I would like to know if this first failed attempt might have caused an issue despite a successful second attempt, or if there is something else wrong.

Still doesn’t work. I’ve set my geo location to Dallas Texas and feels the same. I’m dying way too fast and experiencing major lag compensation knowing I should be winning gunfights. tried with both capping speeds and also setting speeds to 1000mbps and setting congestion control to 70%. Just sucks that online games favor ppl with poor connection and penalizing ppl with great connection. Not sure why that’s a thing as most streamers and competitive players who do live in Los Angeles have fiber internet but somehow not experiencing the same problem? Sucks because I have fiber and thinking it’s that so I ended up getting spectrum to see if there’s a difference and it feels the same. I’ve got both my pc and ps5 optimized specifically for warzone gaming. I now currently have both att fiber 1000mbps internet speeds as well as spectrum 500mbps internet plan and neither fix this desync or lag compensation issue

back to say that this worked. Thanks man. so that was the problem the whole time? cause its been over a year for this error LOL

Interesting ok that actually makes sense. Ill give setting to always on with 100% a go. It was set to auto.

@Netduma Fraser @Redflame Got it! I only had the Congestion Control off because my speeds were way low from what I’m paying for. So, after tech finished, I wanted to verify the speeds up to par.

Will we evere have some kind of parental control or just wifi scheduler.

You don't need to use a manual port rule for Traffic Prioritization unless DumaOS Classified Games / Games Console isn't prioritizing but if that's working for you then great. You have Congestion Control set to Never based on that screenshot so that needs to be set to Always and then follow the steps I mentioned before - I can't provide you with precise percentages that will work because every connection is different, if you follow those steps you'll find the values that work best for you.

No because it barely uses any bandwidth anyway so it wouldn't use 100% and so it would share the excess among the other devices connected

Okay so you're NAT is actually open then but there is a NAT testing server in Brazil that is being blocked making the test fail - could you provide the ID for that server if possible? Then we can add it to the whitelist. You can do that, it either won't make any difference because we try to tag it ourselves or it will help - I don't think we've done any testing on it being enabled/disabled.

Have you checked you're getting internet direct from your ISP modem/router? Either way, reboot that, wait 2 minutes then reboot the R3, wait 4 minutes then check if you have internet

Just keep it at 100% set to Always and it won't be doing anything - I'm still not clear on what the issue is if you don't run the Ping Optimizer test

Hi Fraser, we decided to use the Xbox series X. (Its hardwired to R3 not going through eero).. 1)) it failed to get Nat type, the Xbox said to ensure a certain port open (I think 3544) so I set up port forwarding for that. Still issues. So I had to geo allow Brazil for it to do it. I don’t know why Brazil as I’m in uk. I thought I would raise this as I’m guessing most uk players wouldn’t allow Brazil. 2)) is it worth turning on DSCP tagging on Xbox or is it pointless due to smart boost doing its own DSCP tagging?

So for your test: if a family downloads a game while you are playing call of duty on PC your latency could spike upward of 16ms. If someone is downloading a game on their ps5 and another family member is uploading large files to the cloud your ping could increase to 45ms. For context LibreQos it refers to grades like this: A+ perfect A smooth B minor slowdown C notable impact D severe impact F unusable When I tweak my network to get rid of bloat. I’ll set download and upload at 95 percent do the test, wait a min or two. Then I’ll lower them down by 10 percent or so so 95-85-75 until I get A+ and ideally 0.0.ms + increase. If you found 85 gave you up A+, you could go up by 5 percent to 90 percent to see if it stays A+. If you do increase by 5 percent and it goes off A+ to an A or B just use the ones previously so if 75 gave you A+ but you went up to 80 and got an A, just go back to 75. It’s very important you do your testing when the house is quiet. If a file is downloading or uploading, this is going to add noise to the test. I have a streaming mad family xD so I do mine when the household is asleep. Note: we don’t have the same router, I have the R3 so @Netduma Fraser would have to advise the actual CC settings. But on R3 when doing this testing you set always on and Speedtest bypass off.

And here is the retest from that “C” grade. Any suggestions? bufferbloat-test-results-2026-09-09T01-19-49.pdf

A tech had to come out to service my internet. Turns out that there was an issue with my modem and was swapped. I ran this same test afterwards and resulted and “A”. Later on to now, here’s my results. Here’s my speeds from Ookla Speed Test and from the router itself. Also, for Traffic Prioritization, these ports were recommended, specifically used for Call of Duty. bufferbloat-test-results-2026-09-09T01-10-41.pdf
