david Posted June 8, 2022 Share Posted June 8, 2022 My Netduma R2 has suddenly stopped working. LAN connected devices are no longer able to connect to the internet and connections to the R2 are inconsistent. I can't fully load any of the R2 UI screens they start then fail to complete, often with the message that I've lost connection to the router. I've tested with a stripped down setup with just a single computer connected to the R2, the computer is connected and allocated an IP address but can't fully load the Netduma R2 UI. I've tested all LAN ports on the R2 with the same result. I've tested the same computer with the same cable attached directly to the internet router and it works fine. I've power cycled everything several times and tested with different computers and different ethernet cables with the same result. I noticed that the active port light and the internet connection light on the duma keeps going off for several seconds and the PC indicates the ethernet is not connected then connected when the Netduma port light comes on again. This implies to me that the port or switch on the Netduma is flapping causing the PC to lose the connection. I've tried factory resetting the Netduma but hasn't fixed the problem. I've tried enabling the WiFi on the Netduma to test but I can't get the WiFi configuration page to load. I've tried updating to the latest Firmware but I can't get the upgrade process to complete. The network has been working fine since the R2 was installed in Aug 2021. The network topology is as follows: Virgin Media Business Broadband - Coax Cable - Virgin Media Business Hitron Router - Ethernet - Netduma R2 (v3.0.205) - Ethernet - Windows 11 PC Link to comment Share on other sites More sharing options...
Netduma Liam Posted June 9, 2022 Share Posted June 9, 2022 Are you able to get to the Network Settings -> WAN and enable remote access to tech support? If so, I can then access it remotely and reflash it, that should fix the issue for you. If not, sometimes disconnecting the R2 from power and leaving it for a good 15+ minutes to allow for residual power to drain, it can bring it back from the brink.

david Posted June 11, 2022 Author Share Posted June 11, 2022 It’s very hit or miss if I can access wan config. If I get access I’ll enable remote access and let you know. It’s been powered off for days before I tested again. It was working fine and just stopped working a few weeks ago without any changes to config or network. I’ve removed it from the network for now but I’ve been retesting it over the last few weeks with no improvement. Link to comment Share on other sites More sharing options...
david Posted June 11, 2022 Author Share Posted June 11, 2022 I managed to get access to the WAN config page an remove access is enabled. Do I need to do anything to give you access via the broadband router firewall? Link to comment Share on other sites More sharing options...
david Posted June 11, 2022 Author Share Posted June 11, 2022 Is it possible to update the firmware without using the UI? e.g. via the USB socket? Is it possible to access the R2 UI from the internet facing side of the router? Link to comment Share on other sites More sharing options...

Do I need to do anything to give you access via the broadband router firewall? Could you take a screenshot of this please as it's not something we would have disabled. Remote support has to be enabled otherwise we can't gain access, the R2 WAN IP should also be in the DMZ of the ISP router. 19 hours ago, david said: Is it possible to update the firmware without using the UI? e.g. via the USB socket? Is it possible to access the R2 UI from the internet facing side of the router? Neither of those options are possible currently. Link to comment Share on other sites More sharing options...
david Posted June 13, 2022 Author Share Posted June 13, 2022 Sorry typo in previous message - should read "remote access to tech support" is enabled. The R2 is assigned DMZ on the broadband router so it should be accessible from the internet. Link to comment Share on other sites More sharing options...

The method I've used is a little more granular but unfortunately means you'll now be on an older firmware. If you could now access the DumaOS interface, complete the setup wizard and then re-upgrade to the latest firmware, everything should be fixed for you.

david Posted June 13, 2022 Author Share Posted June 13, 2022 Thanks - I'll have a go now and let you know how I get on Link to comment Share on other sites More sharing options...
david Posted June 13, 2022 Author Share Posted June 13, 2022 That worked - I'm back up and running - I've installed firmware v3.2.453 and run through the setup wizard. Everything seems to be working. Thanks for your help. Link to comment Share on other sites More sharing options...
