andruec wrote: ↑Fri May 11, 2018 9:57 am Okay. Well I've adjusted the logging to be less verbose and hopefully will eventually be able to post more information. For what it's worth my ISP's latest comment is:

'Does the router have a DHCPv6 lease time you can set? Most routers we see, the routers send renew requests each hour but for your connection we only see 3 or 4 requests a day'. Also when the connection dropped at 0257 yesterday they say that a request for an IPv6 address was seen and a response sent.

So it seems like the router either ignored the response or in attempting to update the connection it failed.

Hopefully next time we'll have more information but I still find it very odd that when this happens it always happens at the same time (2am UTC) :-/

The router doesn't have any kind of housekeeping configured for that time, does it?

It's also odd that the 8800NL R2 was doing the same thing (although most of the time that router crashed completely) which was why I replaced it. That router was running slightly old firmware - something released around December 2016 I think. I hadn't updated it because there was a warning about having to do a factory reset and I didn't want the hassle. I decided it was easier to get another router so I could compare config pages side by side.

IDnet should be able to investigate, as 8800NL R2 is a official router they sell, the 8800AXL R2 has almost the same firmware

I'll report back my results on Monday, just to confirm
