Hello!
I have installed DD-WRT v3.0-r51140 std (12/31/22) on my R9000.
The only thing i have done after flashing, is to configure Wireguard client. This works about half of the time. Sometimes from cold booting, connection to internet never comes up. I suspect the killswitch is blocking traffic.
Most of the time this happens i can just reboot and everything is up and running.
I activated syslog a few days ago to see what is happening. Unfortunately i am not sure how to interpret this information. Could you guys help me?

I will move your thread to the more appropriate Advanced Networking forum, the General Questions forum is not intended for router help.
See the forum guidelines with helpful pointers about how to research your router, where and what firmware to download, where and how to post and many other helpful tips:

You showed only one page of the syslog, the syslog is a text file which can be found at /var/log/messages.
With a client like WinSCP you can get that file and and attach as .txt file to your post
What I see might indicate you have a setup problem with WireGuard.
You are setting up a Wireguard Client with IPv6, even if you have enabled and setup IPv6 it will not work (yet). Only the WireGuard server is IPv6 ready.

So remove the IPv6 addresses of your WireGuard client maybe that already helps enough otherwise we need to see the whole syslog when you do not have internet and also screenshots of your settings (Basic Setup, Service, WireGuard etc)
I see. Sorry for incomplete information. I will try your suggestions. Maybe that will do the trick. The funny thing is that it works sometimes and sometimes not...
I had the exact same setup with my old R7000, and there it worked like a charm every time.
i suspect a timing problem with all the various scripts and components beeing innitialized and activated during cold boot and maybe you start your modem at the same time ?
i had a similar experience once with a WRT1900ACS Router and openvpn connection on cold start that didnt work most of the time ...
the solution was not to start the modem and the router at the same time , because the router was always faster than the modem could start up.

That makes sense, although i dont have a modem. Just a jack in the wall directly to the router. My old router took about 2 minutes from cold to fully working Wireguard. This one is about the same. Pretty odd considering the hardware difference between R7000 and R9000.

To recap how this went:
I removed the IPv6 entries like you said, and this seem to have worked.
