Hardware • Qualcomm Atheros QCA6174 802.11ac Wireless Network Adapter: 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.shows the wifi interface wlp1s0 as DOWN but still has an ip address (192.168.1.121).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 : returned

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

and showed wlp1s0 as UP.

and showed active connection to the right SSID.
But pings still didn't get through and I couldn't access the web.
Now I don't know what I did differently but it no longer works.

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

Any help appreciated !
