What precisely are all the issues you're having? You mentioned a couple in other topics but I want to ensure you've put them all here so we can go through them properly

DumaOS 4.0.645

No DNS doesn't have an impact on game performance

Good to hear! DNS won't make a difference for gaming so unnecessary to change it. There isn't a backup settings function currently but it has been requested so may come in future.

I upgraded and resetted with no problems. R3 working fine. Can I ask you a couple of things? Which do you think are the best DNS? (for Call Of Duty) Second, on this firmware update can I make a settings backup? Can't find it in the menu

Thank you for the information you provided. Would changing the DNS have a positive impact on the game?

It's using servers provided by: https://speed.measurementlab.net/#/ As is shown on their site: "We are temporarily running multiple tests back to back to calibrate new measurement protocols. This means results may take a little longer to appear than usual." and generally their servers are not always available/the closest to you. I'd suggest adjusting Congestion Control manually instead to achieve the same effects (Ping Optimizer just changes these percentages). You can find it in Ping Optimizer > Advanced. We suggest starting at 70% and fine tuning based on your experience.

I'll pass your comments along to the team for when they consider new hardware. We do like to keep the price point around the same though so it really depends on hardware cost.

What is the firmware version you're on currently?

Hello, I’m using the R3. When I try to optimize my ping, it doesn’t work and I get the warning “Ping could not be optimized.” I’m connecting from Turkey. My ping is around 25–28 ms. Which server is this ping being measured to? Is there a solution to the issue I’m experiencing?

SAME! also 5 gig fiber user here...I won't use R3 due to its low performance capabilities which would make my subscription to 5G fiber useless. shame because software is second to none (geo filter etc.) @Netduma Fraser please for an "R4" or whatever, equip it with at least one 10G WAN port along with at least one 10G LAN port and wifi 7. if you're feeling generous adding 4 or so 2.5G LAN ports.

Yes, for seven days after that R3 stop working

What's your exact physical home setup and how is it set to allow the XR to have direct access to the internet? This is a NTGR feature so we're not as knowledgeable on it but we'll do what we can to help

Hi Fraser, Can you add me also Thanks

Im trying to set up a VPN so I can connect to my home network with my iphone (using openVPN) while traveling. I am able to connect to the internet via the VPN (I can confirm because my pihole setup blocks ads when connected to VPN, and by checking IP address) but my issue is that no matter what I do I cant connect to my local network, meaning I cannot connect to my computers files, tried reinstalling VPN profiles, changing settings in DumaOS, and googling my issues (unforunately when you search VPN it comes up with only HybridVPN issues) The setting for "Clients will use this VPN connection to access:" is currently set to "Home network only" so I would assume that this would allow connections to computers on my local network? or am I misunderstanding this whole setup? Ive read that it could be a firewall issue or probably even a pihole issue but im not TOO networking savvy so I dont know

Putting yourself in 100ms ping lobbies is setting yourself up for a major disadvantage either way you look at it 😂😂

There won't be no. It'll just be security fixes then, it's unlikely it's based on 3.3, I think it probably reached end of service before they did it.

After flashing the latest official firmware, this is what I see in the router menu: System Info: Uptime: 19:17:29 up 1:37, load average: 1.09, 0.72, 0.56 Router Time: Sat Jan 17 19:17:29 UTC 2026 Board Model: XR700 Firmware Version: V1.0.2.62 DumaOS Name: A7Legit There is no DumaOS version shown starting with 3.3 anywhere in the UI. is there any more information available about the XR700 firmware v1.0.2.62 (A7Legit)? I can’t find any user feedback, changelogs, or discussions about this update anywhere online, only the brief “security fixes” note from Netgear. Has anyone tested it in detail or knows what was actually changed?

@Netduma Fraser The latest early access on the old Netduma R3 isn't perfect. I prefer the official one before your big update. It's been a year since the last official firmware.

it's not that hard prerequisites: - PS5/XBOX only - Crossplay:: ON (CONSOLE ONLY) - Standard Moshpit ONLY - Be patient and be prepared for long waiting times. what to do: - Use your Geofilter to target a server approx. 4,500 km (2,800 miles) away. This will give you around 100 ms ping. - Strict mode: on - Fast search: off - Steady ping: off

Good to hear, don't forget the Early Access firmware as well

@Netduma Fraser Hi Fraser Netduma R3 arrived Friday and installed the official firmware 4.0.540

Thanks for the report, I'll pass it on to the team to update it

That's normal, follow this guide to see if you have a CG-NAT https://support.netduma.com/docs/dumaos-3/open-nat/#cg-nat
