Wlan network interface not showing

Hi, I recently installed arch on my laptop. It lacks an ethernet port so I've had to use wireless, It's been working on and off for a few days but now the wlan interface won't show when I run 'ip link'. I can see it's been detected in lspci and it is written, 'Kernel driver in use: iwlwifi'. It's called Intel corporation wifi 6 (Rev 20).

Ip link https://prnt.sc/22d34k9

Re: Wlan network interface not showing

Check your dmesg/journal for error messages from the iwlwifi module. What did you set up for configuring the network in general? Did you forget to install linux-firmware?

In both journal an dmesg it repeats 3 times that it failed with code -2 but then it says it did load the firmware and detected my wifi card and shows the hardware address.

To configure, originally I unblocked the interface from rfkill then "ip link set wlan0 up" then setup dhcp with dhcpcd then finally iwctl and it worked.

Also I did install linux-firmware with pacstrap.
