[Solved] No network interface showing for wireless card on fresh in...

Hi guys,

I have just installed Arch on my laptop. After rebooting and logging into the system ip link shows only 'lo' and 'enp2s0' entries, no entry for my wireless card. I rebooted into the Arch live system and ip link does have an entry for my wireless card. I don't know where to go from here and have had no luck searching for a solution, any help would be appreciated.

Also, I have previously installed Arch on this laptop without this issue.

Arch install dmesg output
Arch live env dmesg output

Arch install lspci output (Arch live env output is identical):

03:00.0 Network controller [0280]: Qualcomm Atheros QCA9377 802.11ac Wireless Network Adapter [168c:0042] (rev 31)
	Subsystem: Dell QCA9377 802.11ac Wireless Network Adapter [1028:1810]
	Kernel driver in use: ath10k_pci
	Kernel modules: ath10k_pci

Arch install ip link output:

    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

Arch live env ip link output:

Did you install linux-firmware?

Did you install linux-firmware?

pacman -Ss linux-firmware shows that it is not installed. It shows as "core/linux-firmware 20190923.417a9c6-1 (base),"  does that not mean it should have been installed by pacstrap'ing base (which I definitely did)?

After installing linux-firmware and rebooting the wireless card now shows up with ip link so I guess that's solved. Thank you for your help!

Re: [Solved] No network interface showing for wireless card on fresh in...

it's an optional dep of the standard kernel; you have to pay attention to what pacman tells you. I know it's a lot with pacstrap, but it's important.

Where it says base, it's talking about the group that isn't used anymore.
