Vigor 2862n rebooting at 00:00 every Sunday was created by af7567
Hi
I have a 2862n connected by WAN2 to a FTTP modem and the PPPoE login is handled by the DrayTek router. Everything is working fine but for some reason it keeps crashing/rebooting at 00:00 every Sunday. When it restarts this way the WAN2 connection drops to 10Mbps instead of 1Gbps and I need to restart the router again to get it back to 1Gbps. The only schedules that I have ever set on the router are to disable WiFi at the weekend which does "force down" from 00:00 to 23:59 on saturday and sunday. I have cleared those schedules now to check if the same problem happens next weekend.
I set up email reporting and got the following emails after tonights crash:

I don't know if that explains what causes the crash.

Is there any particular reason for running this Release Candidate?
Maybe the public release will behave better? https://www.draytek.co.uk/support/downloads/vigor-2862 (Currently 3.9.4.1)

Only to someone with a copy of the Vigor 2862 source code - which unfortunately, is no one here :(

So you have nothing set at >


GUI > System Maintenance > Reboot System > Auto Reboot Time Schedule



You could try setting up a reboot schedule and then deleting it again.

I wondered why it said RC5 too, but that is actually the public version 3.9.4 which was the latest version when I downloaded it a few weeks ago. It's not the BT version though because I had been told by the ISP to not use a BT firmware version. But since 3.9.4.1 is out now I should give that a try when someone is back in the office :)

Good idea, I will give that a go too.
Still very strange that this unexpected midnight reboot would cause the ethernet connection to the modem to only go 10Mbps when it's fine at 1Gbps the rest of the time. Is there really an option somewhere to "reboot and set WAN2 to 10Mbps" :)

Draytek at their best :roll:

It's not the BT version though because I had been told by the ISP to not use a BT firmware version.


I was a long time user of Virgin Media, so when I moved house and had to switch to VDSL, I had no idea which firmware version to use (on my 2860). I just tried 'em all - and found significant differences in speed...

(There again, you'd like to think your ISP would know best - unless of course, it's Talktalk :roll: :lol: )

To add - at one point - in the Virgin Media days - Draytek had me switch to one of the 'vectoring versions' (for want of a better phrase). I couldn't understand what difference this would make (given the 2860 was using WAN2 to connect to a VM Super Hub. But it did :!: )
