Wifi card recognized by installation media but not on installed system

Hi everyone,

I'm installing arch on an MSI GS43VR 7RE Phantom Pro.
Everything seemed to go well until I rebooted into the newly installed system and found that I couldn't connect to the internet.

I tried to connect through wifi-menu as I did from the installation image and rather than seeing the network selection menu,
I was greeted by the following error:

# wifi-menu
Invalid Interface Specification
Usage: wifi-menu [-h | --help] [-o | --obscure] [INTERFACE]

Interactively connect to a wireless network on INTERFACE using netctl,
If only one wireless interface is available, INTERFACE can be omitted,

Arguments:
  -h, --help     Show this help
  -o, --obscure Show asterisks for the characters of the password
                      and store the password as a hexadecimal string

Clearly something wrong with the interface so I looked at what interfaces ip link shows me:

# ip link
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

So it only sees loopback... not even my ethernet controller.

lspci shows:

# lspci -k | grep Network
lspci: Unable to load libkmod resources: error -12
3e:00.0 Network controller: Qualcomm Atheros QCA6174 802.11ac Wireless Network Adapter (rev 32)
    Subsystem: Bigfoot Networks, Inc. QCA6174 802.11ac Wireless Network Adapter

It seems like there are some firmware drivers in the installation media that aren't getting copied over by pacstrap,
but everything I've read on the arch-wiki indicates that my wireless driver should be included in the linux-firmware package.

What am I missing?

for reference, this is what the installation media outputs when I run ip link:

# ip link
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: enp61s0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc nq state DOWN mode DEFAULT group default qlen 1000
    link/ether **:**:**:**:**:** brd ff:ff:ff:ff:ff:ff
3: wlp62s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP mode DORMANT group default qlen 1000
    link/ether **:**:**:**:**:** brd ff:ff:ff:ff:ff:ff

Thanks in advance for your help

`pacstrap` does not "copy over" anything; it installs a new base system which indeed is not what is on the iso.  This is specifically noted in the installation guide for networking.

So we just need to figure out what is needed for your hardware and get it installed.

Have you worked through this yet?

Can you check what module is in use in the live system for your wireless card?

Re: Wifi card recognized by installation media but not on installed system

Your installed kernel may be different then the booted one, like in [1]

please post

$ pacman -Q linux
$ uname -a

I did and as I have a qualcomm 802.11ac it would appear I need the ath10k driver but I cant seem to find that in the pacman list. In fact theres nothing for qualcomm or atheros at all

I read through the link at the bottom of your post and realized I also forgot to mount /boot before installing the kernel... I feel like an idiot bit that fixed it. I can access my wifi card now. Thank you so much
