Seems that you are digging in the right direction... I suppose that is not good!

Sorry for the confusion, just wanted to say that wired LAN and WLAN leads to the same results.
What services are you using on your router?
 
Nothing special - is this something that has to be installed separately?
I need to know which services are enabled on your router, amtm and entware.

Very well. Excellent feedback. I found your problem: VPN. I found that it uses the unbound_manager script. I recommend looking for support in the script topic. unbound_manager

Thank you rgnido for you advice. I still don't understand how you came to this conclusion but I will try to dig in this direction. I plan to setup the router and all the installed stuff completely from Zero again. Just to avoid too much effort based on a bad configuration. Thanks again!

What response do you get if you lookup router.asus.com from the Mac? That would answer straight from dnsmasq without forwarding to unbound.

Notice that we had discussed in another post.
The dns resolver must communicate with the VPN provider's dns in order for the local query cache to exist.
If you use a VPN client, you must inform the unbound credentials. Your unbound is communicating with root servers only.
In a sinulation without unbound, only with dnsmasq:
the VPN dns will be read by the file /tmp/resolv.dnsmasq and will be cached with the option cache-size=1500.

I deactivated the VPN (told the IP 192.168.1.15 to choose WAN instead if VPN within the GUI). My real IP was shown in IP-leak test and DNS leak test. But I still get the same query time at about 95-100msec.
 
Try to ping your router from your mac.
What's the response time?

Hello all,

thank you for your help so far!
Tonight I did a nuclear reset of the router as mentioned by L&LD. I also formatted the JFFS partition.
without any addition software I executed the dig command in the terminal again:

I still get the same query time at about 95-100msec. Even without unbound installed!
Stating this its clear now that unbound is not causing this problem. Sorry for posting in this forum!
Ping command to the router leads to about 0,3msec - so I have to search the problem somewhere else... Thank you again for your advices so far!

I’m interested in the dig response time.

executed "router.asus.com" directly in the terminal of my MAC:

Code:
Christians-MacBook-Pro:~ chris$ dig router.asus.com

; <<>> DiG 9.10.6 <<>> router.asus.com

;; ANSWER SECTION:

Does not make sense right? - its like my computer adding 105 msec query time on top...
