More a FYI, I have two clients, one in Bude, Cornwall, the other Bideford, Devon. Around the same time last night both clients who are using a 2670 starting having their routers reboot constantly. They connect to the internet and then after around 20 seconds restart. I have been to Bude and when the router is unplugged from the wan, will stay up. But the moment the wan is reconnected, the reboots start again. I have replaced the Bude router with a non Draytek brand and is stable. I will go to Bideford in the morning to swap out their one.

I realise the 2670 are an older router, however it is supposed to be compatible with SoGEA (which i'm not sure has been enabled in both places yet) and the firmware was the last one available.

However, Bude is connected via Openreach Fibre, Bideford is VDSL via TalkTalk Business. So i'm wondering is there's a firmware bug. No idea why it's doing it. The reboot clears the logs so i'm not able to pin the cause down.

Posted here in case anyone else suddenly gets unexplained restarts.

Better read this article and all the comments below it.

I have had the same issue but when I disconnected the main WAN and left the 4g to automatically kick in the rebooting stopped? As soon as the main WAN is reconnected it starts the boot loop again? Upgraded the firmware everything is OK.

I have to say I'm very disappointed at having seen nothing official from Draytek on this issue directed to Partners, not even those (like us) who have invested in DCNA training and qualifications. I learned of this issue from a client's ISP yesterday when on site troubleshooting an internet issue. The client is now retired and has an (admittedly old now) 2760, but has had the latest available firmware installed for ages.

If Draytek monitors this forum, can you PLEASE engage with your Partners and advide on a timescale for any fixed firmward updates? I don't want to take a large chunk of our entire supported device inventiry off ACS - it would cost us huge amounts in time and some cases travel to restore them, and the advice that seems to be being given just to disable remote admin access is not acceptable without more authoritative data on devices and firmware versions that are without doubt secure, and time to fix on other models.

https://www.draytek.co.uk/support/downloads shows many devices on the main page (which I've always thought of as 'Supported Devices') which are older, and there's a separate 'Legacy Devices' folder off that which is clearly just that. Does Draytek need to shift a load of devices from the main page to 'Legacy Devices'? We need to have, again a document I've never seen, a formal support roadmap for each model, listing end of sale, end of support availaibility and end of life. I've never seen anything like that if it exists. 2860's and 2862's continue to get FW updates, but in one of the articles on this rebooting problem I've seen them listed as EOL. It's not a Draytek article and therefore not authoritative, but the whole situation is unclear and needs clearing up by Draytek.

Come on Draytek, you are costing your loyal Partners a lot of money in wasted time and your poor communication here. You need to sharpen up your communications and action on this so it's clear to us what we should be supporting and what we shouldn't. This needs to happen very quickly before Draytek as a brand loses all credibility in the marketplace.

As a 'new' member (since 2017), my posts had to be approved, so whilst it was waiting, the ISP article popped up which explained everything on another thread. But thank you for the reply

I have to say I agree with this 100%. Draytek UK have been silent on both this forum and the Draytek facebook group. I think Draytek Australia have posted something but nothing about the root cause of this issue.
I think this will be the final straw for some and Draytek products, I know I'm certainly looking at other options.
