System and Network configuration • Can't get wifi to work on fresh debian 11

Hi,

Advanced debian noob here (got the basics right but not much more i think).
I can't get the wifi to work on a fresh debian 11.

Code:

ip a show

shows the wifi interface wlp1s0 as DOWN but still has an ip address (192.168.1.121).

Code:

ip link set wlp1s0 up

returns no error at all, but the interface still shows as DOWN.

Weirdly enough, at login, I can see the dashboard WLAN indicator connect, show signal as green, for like a second, and then nothing.

I have tried manually setting things up in /etc/network/interfaces.d and /etc/network/interfaces, although I don't think I have what it takes to figure it out on my own (yet).
I'm positive I have commented out every modification I have made, to try again fresh.

UPDATE : returns

Successfully initialized wpa_supplicant
ioctl[SIOCSIWENCODEEXT]: Invalid argument
ioctl[SIOCSIWENCODEEXT]: Invalid argument

Now shows wlp1s0 as UP.

And shows active connection to the right SSID.
But pings don't get through and I can't access the web.

For info : the network controller lists as Qualcomm Atheros QCA6174 802.11ac Wireless Network Adapter in lspci
Laptop is Lenovo 14W.

Any help appreciated !
