WIFI network takes a very long time to establish on my ASUS laptop

On my ASUS Vivobook X509ja, the wifi network takes a long time to establish when logging in, waking up from sleep (looking at the small symbol at the bottom right of the screen).
It's over 30s and can be up to 2 minutes!
The PC (equipped with an SSD, an Intel Core I5 and 8 GB of RAM) was delivered pre-installed with W10 and at that time the establishment of the network was almost instantaneous.
 
Then there was the forced passage to W11 23H2 (ed family)
 
Finally, "heavy" software "had" to be installed there.
 
I have two independent WiFi networks: one native to the box and the other generated by a Netgear router; the behavior is the same on either network.
 
I would like to know the cause of this problem which is very painful to use or a procedure to find it...
Or a bypass or parade...
