[solved] wi-fi 6 (AX) card does not connect to wi-fi 5 (AC) router

Hi

I have replaced the slow wi-fi 4 card of an old laptop with a wi-fi 6 (AX) one, but I'm unable to connect to my AC router since then.
Even the bluetooth feature of the new card works as expected, the laptop finds both 2,4ghz and 5ghz networks, but none of them connects.

Any idea on how to make this new card to connect?
Thanks.

Please post the un-grepped system journal for a boot with the issue.  The grep removes context.  Please replace each redaction with a unique token.

My modem/router was configured to block unknown mac addresses and I completely forgot about it. Sorry for my dumbness.
