[SOLVED] Wireless configuration: firmware not loaded?

Question

Dear all,
I would like to configure my Wifi schede in my Arch installation.
I started following the guide in the wiki (https://wiki.archlinux.org/index.php/Wi … figuration)
but I get to a point where I have an error but don't know how to proceed.
Following the guide I did:
lspci -k
02:00.0 Network controller: Qualcomm Atheros AR9485 Wireless Network Adapter (rev 01)
Subsystem: Samsung Electronics Co Ltd Device 4105
Kernel driver in use: ath9k
Kernel modules: ath9k
So that it seems that the driver for my card is installed and in use.
Next I did:
ip link
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: enp1s0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast state DOWN mode DEFAULT group default qlen 1000
link/ether 20:89:84:0f:7d:91 brd ff:ff:ff:ff:ff:ff
3: wlp2s0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN mode DEFAULT group default qlen 1000
link/ether 50:b7:c3:24:85:c1 brd ff:ff:ff:ff:ff:ff
From the output I deduce that wlp2s0 is the name of my interface, so I try to turn on the interface:
ip link set wlp2s0 up
##NO OUTPUT IS DISPLAYED##
Next I do:
dmesg | grep firmware
[ 11.882857] platform microcode: Direct firmware load failed with error -2
[ 12.143983] platform microcode: Direct firmware load failed with error -2
[ 12.148247] platform microcode: Direct firmware load failed with error -2
[ 12.148586] platform microcode: Direct firmware load failed with error -2
dmesg | grep ath9k
[ 1781.365268] Loading kernel module for a network device with CAP_SYS_MODULE (deprecated). Use CAP_NET_ADMIN and alias netdev-ath9k instead.
I have no idea what I have to do at this point. How do I enable my wifi card and manage my network (possibly with some graphic tools for my MATE desktop)
Thanks a lot in advance for the help!
Cheers,
Luca

Hi, I managed to use my wifi using NetworkManager.
In the wiki it says that I have to be sure no other service that wants to configure the network is running.
Everything seems to work fine now, but can you pleas check my output of "systemctl --type=service" and
let me know if I need to disable any service?

LOAD = Reflects whether the unit definition was properly loaded.
ACTIVE = The high-level unit activation state, i.e. generalization of SUB.
SUB = The low-level unit activation state, values depend on unit type.
29 loaded units listed. Pass --all to see loaded but inactive units, too.
To show all installed unit files use 'systemctl list-unit-files'.
