Iw dev connect - Operation not supported (-95)

Hello and thanks for dropping by,
The problem I’m having is that after I got my wireless interface to work (indicated as up):
$ ip link list
3: wlp0s20f3: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN mode DEFAULT group default qlen 1000
link/ether c6:ec:15:6f:2d:68 brd ff:ff:ff:ff:ff:ff

I try to connect to my WiFi which the interface found (via the command iw dev INTERFACE scan):
$ sudo iw dev wlp0s20f3 connect Ksenia key 0:0544880620
command failed: Operation not supported (-95)
$ sudo iw dev wlp0s20f3 connect Ksenia key d:2:0544880620
command failed: Operation not supported (-95)

I couldn’t find anything regarding this “Operation not supported (-95)” which was relevant to the iw command.

I was following the Arch Linux Wiki Guide on the subject of Network configuration/ Wireless.

I also disabled my Ethernet so it wouldn’t interfere with the Wifi, but it didn’t work.

Software notes:
I installed Manjaro a few hours ago
Manjaro Illyria 18.0.4
I ran rfkill to make sure it wasn’t the problem:
$ rfkill list
3: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no

So basically, I think the problem has to do with the Wifi interface itself (and making it work in conjunction with Manjaro). Because it says Wi-Fi is disabled in the networks manager window

IIRC NetworkManager is used on all editions to manage network (devices), Try nmcli, see

In the wiki page it does explain that using another service disables nmcli.
I might as well post that:
$ nmcli device
enp1s0 ethernet connected Wired connection 1
wlp0s20f3 wifi unavailable –
lo loopback unmanaged –

Manjaro Illyria 18.0.4 is very old 21.3.7 is the main xfce etc version

Very true indeed.
@Raziel17o1 : try with a current/up-to-date iso/installation.
Also please post more system information, see

I don’t have an extra CD the burn a new image on, I was hoping to install and then update the OS to the current version anyway, but currently it looks like an unlikely option.

If you have a spare fresh drive around, you can use ventoy. Just place the iso in the storage, reboot e select ventoy at the boot menu.
