I think i was able to narrow down the problem.
Out of curiousity i started playing around with the different wifi security options in my router.
Turns out:
- Disabling wifi security → Notebook can connect without problems to wifi
- Enabling WPA + WPA2 → Notebook can connect without problems to wifi
- Enabling WPA2 CCMP → Notebook can connect without problems to wifi
- Enabling WPA2 + WPA3 → Notebook can’t connect to wifi and presents me the infinite password prompt
While i’m not surprised that the old intel wifi card doesn’t support wifi authentication with wpa3 i’m kinda surprised that there seems to be a difference between pure wpa2 ccmp and wpa2 + wpa3 mode (as wpa2 should still be an available option to use).
Gonna keep researching …
