WLAN Repeater, no Internet

Good morning everyone,

I have the following problem. I would like to connect a router to a client WLAN and then set up my own WLAN. This config used to work, but unfortunately it no longer works. However, I'm no longer sure which instructions I used back then.

The furthest I managed was to set up my own WiFi, but it said "no internet connection"

See if this fits the bill:

I followed the instructions. Sometimes the connection works under diagnosis and sometimes it doesn't
