NEW R3 FIRMWARE - DumaOS 4.0.1510

[Netduma Alex]

Hi everyone,

We are excited to roll out a major new firmware update for the Netduma R3, packed with significant improvements and optimisations we’ve been developing over the last year.

This is a comprehensive release. You will experience a noticeably faster user interface, improved Wi-Fi auto-channel selection, new dedicated front panel LED controls, and key memory and security patches designed for long-term stability.

Alongside these broader enhancements, we have completely overhauled two core systems:

Device Manager & Classification Engine
We have implemented a completely new Device Classification backend that allows classification and categorisation rules to be updated dynamically over the cloud. Just as our DPI system automatically updates to support new games, DumaOS can now recognize and categorize newly released smart devices as soon as they hit the market.

To help make Device Manager as accurate as possible, users can now optionally report incorrect classifications directly to us. This reporting is purely opt-in, fully anonymised, and directly helps improve detection accuracy for all users. You will be asked if you want to participate the first time you make changes in Device Manager, and you can easily change your preference at any time from the Settings menu.

 

Geo-Latency
We have fine-tuned Geo-Latency to work more reliably with our currently supported titles, while expanding support to include more games, such as Battlefield 6. We have also reduced its footprint under the hood to improve overall system performance.

Behind the scenes, we have been working hard on several exciting new DumaOS features that we are almost ready to share. Expect to hear more about those very soon.

Thank you for your patience in waiting for this new firmware, and thank you for being a Netduma customer.

@Netduma Alex With this update I've noticed that the router no longer recognizes the computers system name. For example my computer is named Jamie-PC and in device manager the router knew and automatically named me on the router as Jamie-PC. But now with this latest firmware it names everyone as Microsoft Windows Computer and I need to manually rename everyone myself. 

Additionally, there are less device manager icon options to select for each device on the network now. 

There is no longer a inique icon for Wi-Fi extenders like in the past. Not a major issue but strange to remove options that were available before.

This is actually an intentional change. For most users, we thought that the hostname wouldn't be useful. For example the default hostname for a Windows PC is usually DESKTOP-XXXXXXX, where XXXXXXX is a random series of characters. In this scenario, the name "Microsoft Windows Computer" might be more useful.

However I can see that for users who customise their hostnames, or for users with lots of the same type of device, this change is actually a step backwards.

Perhaps we could add a toggle to display hostnames instead, or perhaps we could put the hostname in brackets after the assigned name? I'll discuss it with the frontend guys.

Due to the Device Manager overhaul, some of the device/icon mappings were broken. If for example we update the name of a device type from the cloud, it might no longer link to the correct icon, which I think is what happened in this case. I will talk to the frontend team and make sure we get non-generic icons for everything.

Hey, quick question before I sign up with a new ISP. They're giving me a dedicated fiber line with a static IP on a /31 (mask 255.255.255.254). Their ONT will be in bridge mode going straight into the R3, no PPPoE.

Does the R3, with this new firmware DumaOS 4.0.1510, accept a /31 subnet mask in the WAN static IP settings?

Thanks!

I'll respond in your topic

So we can use this update now?

My update button in the Duma is greyed out

Just a heads up.

The Mac Address Cloning area under Advanced WAN Details is constantly trying to load/buffer the address. This is on all Internet browsers and on the app.

I am also unable to enter and save any DNS Override or MTU settings as pressing the save button doesn’t save your inputs. This is likely because the Mac Address Cloning area is still trying to load. This also happens on all browsers and the app too.

Thanks.

[Redflame]

Just updated. I really appreciate the hard work @Netduma Alex and the team put into this update, plus thanks to @Netduma Fraser for always being there whenever lag managed to reappear. 
 

After redialling in CC — BO7 + BF6 feels rather smooth 😇, yay!

Yes you can use it - download it and upload it to the router manually instead

We're aware of that saving issue, that will be fixed

If you plug a laptop, pc or like an Xbox series into router via Ethernet can you open up router admin page at 192.168.77.1 on said device?

Does your internet provider use PPPoE or DCHP/IPoE? Is the R3 on an FTTP connection directly plug into an Ont or are you using upstream (DMZ)?

I would suggest turning R3 off, there’s a power  button at the back, then unplug it at the socket wait two mins, plug it back and turn R3 back on. If you have an ONT maybe turn that off as well. Turn ONT back on first, then when that’s power on with green lights/connection up status, turn R3 back on.

If that fails you could factory reset the R3 via the pinhole.

[AymmmR]

I already reset the device via the pinhole. Still not working. I use a Pc and I can't open up router admin page too. My provider use DHCP/IPoE. No Ont, no DMZ.

So what kind of internet do you have Coaxial, FTTC? Is there a device upstream like a modem or isp router that bridges your R3 to your internet? Have ensure the cable going into Wan Port isn’t loose or damaged/faulty?

When you pinhole reset how long did you hold it in for? I think it took us 20-30 seconds. 

[AymmmR]

1. It's a Swisscom FTTP fiber connection. The R3 was connected downstream via a Swisscom Internet Box, since the R3 cannot handle Swisscom's VLAN 10 directly on the WAN port.

2. The cable and ports are completely fine, verified with other devices.

3. For the pinhole reset, I held it in for over 30 seconds multiple times.

As mentioned, the unit is completely bricked: the power LED just blinks indefinitely, there is zero RGB lighting, the Swisscom box detects it as offline/powered off, and it doesn't respond to any reset or recovery mode. It ran fine for 2 years and suddenly died.
