I'm as confused as u are on this I don't know if the router was malfunctioning or what but for some reason on the congestion control on the advanced setting u can choose low latency only or auto or always on when I would set it to alwasy on it would cause some of the servers inside of the radias to be blocked I then did a factory reset and left congestion control on auto and it for some reason stopped the servers from being blocked

Yes, your Netduma works perfectly with YouFibre by plugging straight into the ONT via DHCP—no modem mode needed. While exploring the best broadband plans, consider Zoiko Broadband as well for flexible hardware setups, low gaming latency, and fast full-fibre speeds. Their reliable symmetrical speeds let you make the absolute most of DumaOS's traffic prioritization features.

You're doing everything right and there is no setting preventing you from getting a game - there are similar servers such as Italy that don't always seem to be available but seem to come online in specific circumstances such as times of heavy population e.g. peak time or the weekend so that's very likely the case here. Essentially if you're forcing them and you definitely are because it's not letting you into anything outside your radius then it is the game stopping you connecting to them.

We never said we were working on one and with recent US laws around manufacturing routers it would make it even tougher for a small company like ours

You don't need to factory reset for a new ISP just change the auth details

That doesn't make any sense they're two independent features - if you could provide a video reproducing the issue and showing you fixing it that would be really helpful but no worries if not

I will reach out if I need help or have problem with R3 > Eero. My family have decided to switch isp. Should I factory reset and reset up or just flip auth? New Provider would be pppoe aswell.

Ensure Geolatency is disabled. Strict mode would need to be on. From my own experience I only get Sweden for zombies or endgame. From my own testing, the game does prefer Paris and Frankfurt for gameplay. I know Poland is used occasionally for multiplayer. When you first open call of duty, before game servers appear you should see two servers appear in Ireland I would say true white listing these (they appear to be auth servers) if I don’t polygon Ireland my game can be weird. SBMM may be an issue, but it could also be pop is lower on those servers. Effectively you connection times out to blocked server or your router shows the game you got 250+ making matchmaking avoid that. Have you tried changing your dns on ps5 from isp default to cloudflare?

I am a uk player too. I found BO7 is quite strict on letting you on them USA servers, MW3/Bo6 I manage to play on Atlanta/NYC servers but bo7 will only put me on Virginia/D.C server in private match (mp). It seems unless you have American based player as party leader the game fights you here. Ensure you do a polygon around Ireland or whitelist the servers there - these are not gameplay servers, they appear to be auth servers. If my console can’t talk to them COD freaks out and won’t let me play.

Thank's a lot Fraser!

I ended up fixing the issue basically what was causing the problem was congestion control being alwasy on I turned it to auto and things are working like normal

Title: COD Matchmaking Stuck / Won't Connect to Local Servers with Ping Assist 0ms (Netduma R3) Hi, I’m having an issue getting Call of Duty Multiplayer matches on local servers when keeping my latency low. Router: Netduma R3 Game & Platform: Call of Duty Black Ops 7 (PS5) Setup: Custom polygon covering ~6 local data centers (Finland, Sweden/Stockholm, Poland). Strict Mode tried both ON and OFF. Ping Assist is set to 0ms. Problem: When Ping Assist is set to 0ms to force local servers (under 30ms ping), Multiplayer match search hangs indefinitely ("Searching for a match...") with 4 core game modes selected (TDM, KC, Domination, Hardpoint). Note: This issue only occurs in Multiplayer. Other modes like Endgame and Zombies work fine and connect without issues. Details: If I increase Ping Assist slightly, Multiplayer immediately finds matches on Central European servers (Frankfurt/Amsterdam), but the ping goes up to ~39ms, which I want to avoid. Account is completely clean (No Ban Detected on Activision page). Flushing cloud / resetting network hasn't helped. Is COD matchmaking simply ignoring these 6 covered local nodes in Multiplayer in favor of Central Europe due to SBMM, or is there a specific DumaOS 4 / Geo-Filter setting I should adjust so the game actually routes into the allowed local polygon faster? Thanks for any help!

Le Flint GLiNET ne supporte pas l’accélération matériel avec QoS … Pour information !

I got tired of waiting the WiFi 7 router and bought the Glint Flint 4, spec wise it's and absolute beast, I hope you can be faster adopting technology and adding more features. When WiFi 8 is announced try to be faster or lose potential customers again.

So usually I will turn gio latency off then I will set congestion control to always on but for some reason if I move the gio radias at all the router will start blocking servers inside of radias also if I turn on ping assist the router will also block servers inside of radias

Just add your Xbox to the Geo-Filter and change the settings as you want then start up the game

So after a reset what Geo-Filter settings are you changing immediately? Can you provide a screenshot of the Geo-Filter page showing what you see when it happens please?

Hello! I have all the Netduma, i'm enjoying a lot the R3! Can i have the Beta Access if there is one ? Thank's for all!

I know if I’m on pc I have to set my pc to Ps5, delete, readd, and then start the Cod for the geo filter to work. if I play cod on Xbox console, can I just set my location and have it work when I start the game each time? Or are there a million work arounds on this trash router to get it to work?

I'm running into some issues with the netduma router basically what's happening is the netduma is blocking a server that is inside of the radias I don't understand what's going on I have tried to factory reset it seems to not help the issue also after I do the factory reset and I get to the setup screen it will freeze on the screen that shows the continue button I then will have to unplug my isp router and plug it back in order to get past the continue screen for the setup

It sounds more like a Netduma R3 configuration issue than a problem with your Virgin Media connection, especially since the router itself gets 470–500 Mbps. I’d check QoS/Congestion Control, bandwidth limits, and any traffic prioritisation settings you changed for Black Ops 7. Try returning those settings to default and run another speed test. If the speed returns, you can adjust the gaming settings gradually without limiting the whole connection.

Ah okay, wasn't listed there when I had a look, I wouldn't count on them doing it too often, I imagine it only occurs if there is a serious security issue to fix.

They updated the XR500 router 14 august 2026... I have updated it to Firmware Version 2.3.5.152.. So they still release security updates.
