@kooper2013: And everything that relies on check_ps (and process monitor) that goes askew will be because cron is disabled. Is this over wireless or something? It would help to know all the details of the issue and have screenshots of all applicable settings to see where things are going awry.


LOG attached, diverted to USB. ntp disabled, cron enabled.
Screenshots won't help, I'm quite sure. The router is not reachable by WLAN nor LAN, no pings returned.

Last line is always
Jan 1 23:16:01 home user.info : [upnp] : maybe died, we need to re-exec it

Set time to 23:50 manually and waited. So disregard the times in the LOG. The router will stop as soon as 0:00 is shown in GUI (+/- 1s).

If left in this status over night, the router is cold, as if it switched itself off.

Going by your log, wireguard requires ntp to be enabled. It looks as if dnsmasq is in a restart loop - not sure if that's ntp or dns failure / wanup failure / config problem. Also, I don't know why you have upnp enabled, but unless there is a specific reason why it's enabled, I would disable it. Seems like worst case is reset, hard reset, and start from scratch.

WireGuard doesn't seem to require real time (first thing I checked).
I know upnp is unsafe. It is only enabled in my internal network, not available from outside.

I'll try older builds, now that I'm able to reproduce it without waiting for real midnight. But little time these days...

Thanks for looking at it, @kp!

Router/Version: NetGear R7000
File: netgear-r7000-webflash.bin
Firmware: DD-WRT v3.0-r47911 std (12/23/21)
Kernel: Linux version 4.4.274
Mode: Router, wifi/eth, 2 subnets, 2x WG tunnels
Previous: r47074
Reset?: N
Status: Working after reboot

upgraded using:
Code:
wget http://download1.dd-wrt.com/dd-wrtv2/downloads/betas/2021/12-23-2021-r47911/netgear-r7000/netgear-r7000-webflash.bin
write netgear-r7000-webflash.bin linux &


All working - flawless upgrade , easy and quick.

Differences noticed:

1. I run 2 WG tunnels to different endpoints at the same VPN that also use the same key. In previous version the "WireGuard Status (F5 to refresh)" section just displayed details of the first tunnel, for both first and second tunnels. It was only a cosmetic problem, the connection details were correctly shown in the syslog. BUT - it is nice that it is fixed now !! Thank you Smile Each tunnel now shows its own details in that section.

2. Both my WG tunnels use Policy Based Routing (PBR). That section has now been expanded with more options/granularity. My own PBR details did not carry over to the new version (this is expected, and there is a post about it ). For me, it was just easier to re-enter those details into 47911. And - also to disable "Query DNS in Strict Order" on the Services page...

Over the last few months, I have had some stability problems with my 2nd WG tunnel. It seems to stay up for about 3 weeks and then requires a bit of a reset to keep going. The first WG tunnel does not have those problems. Anyway, I am curious to monitor over the next couple months to see if that changes/improves with this new version. EDIT - I suspect the VPN provider is at fault for that.

MY thanks to all the devs and all those who tested #47911 Smile

In your attached log, the following entry did show up multiple times:
Code:
Jan  1 23:01:37 home user.info root: WireGuard stopped waiting after 91 seconds, trying to set routes for oet1 anyway, is there a connection or NTP problem?

Better assume all kinds of encryption protocols need correct time. Unbound DNS definitely needs it.

Did you setup NTP time client by entering a domain name? Try IP addresses, or leave the field blank!

There were multiple mstpd errors as well... I dunno that one. Per kp69 said, maybe you should just disable uPnP to reduce the amount of logging.

I will not go into detail but WireGuard when implemented on a device without a RTC needs the correct time.

That is what the log is trying to tell you Smile

Three weeks without a disconnection? Wow that is something which is very rare with my provider (Keepsolid).
I use the fail over setting so that the next tunnel will start when the first goes down.

Sometimes after days sometimes after 1 or 2 weeks, it is either too busy and I am kicked off or down for maintenance, they have acknowledged the problems and are taking action, WG is increasingly popular Smile

Hi @egc, @kp, @mwchang,

this is an older issue. I went back to r47171, which also stops at 0:00. Then I decided to give up.

Now cron is disabled, ntp (and upnp) enabled on r47911 and it doesn't stop at 0:00. Don't know what the problem is.

Remarks:
ntp was just disabled for the tests (I needed to set time to 23:55 to wait just 5min rather than 24h).
wg works at least for a few minutes with the wrong time.
The spam in the log about upnp isn't bothering me.

It looks like you are setting the routers own IP address as DNS server, DNSMasq then starts querying itself and eventually could lock up.

Only use trusted DNS servers like 9.9.9.9 or 1.0.0.1 or 208.67.222.222 in Static DNS 1-3

On services page Disable "Query DNS in strict order"

Do not put anything in the Time Server IP/Name field just leave it blank only set the time zone.

Rebooting your router every day should not be necessary

You have guest wifi but the guest VAP's are not unbridged so not really safe but it depends on your guests Smile

Wifi Country settings Japan is not very well tested for testing use USA

After a lockup it seems you put the same settings in again not sure if that helps
