Wifi repeater unique SSID and dns

i am following the tutorial at https://doc.turris.cz/doc/en/public/repeater
Everthing seems like working beside DNS. I am able to ping and other IPs but no domain namens. Tried to enable dns forwarding with but that did not do the trick.
Another issue is that sometimes the uplink wifi goes down but does not come up again. In that situation i have to reconfigure from the beginning.
Can somebody help?

I am going with https://github.com/openwrt/packages/blob/master/net/travelmate/files/README.md now. Seems like its working great :slight_smile: There is also a nice support thread: https://forum.openwrt.org/t/travelmate-support-thread/5155
