[SOLVED] Connect to internet after installation

Hello, I'm trying to install Arch at laptop first time, and stuck with next problem

While installing, I was connecting to internet using wi-fi  through iwd, command

iwctl --passphrase ... station wlan0 connect My_Wi-Fi

After rebooting and entering system not from installation medium, I can not to connect internet:
ip link doesn't show wlan0
iwctl mostly hang with Waiting IWD to start.... (One time after n-th reboot it finally started, but show no devices)
Also rfkill list shows only bluetooth.

dmesg | grep -i firmware show several bugs:

[Firmware Bug] : TSC_DEADLINE disable due t Errata; please update microcode to version: 0x25(or later)
DMAR: [Firmware Bug]: No firmware reserved region can cover this RMRR [0x.....]; contact BIOS vender for fixes
DMAR: [Firmware Bug]: Your BIOS is broken; bad RMRR [0x...]
ACPI: [Firmware Bug]: BIOS _OSI(Linux) query ignored
[Firmware Bug]: Invalid critical threshold (0)
[Firmware Bug]: ACPI(PXSX) defines _DOD but not _DOS
bluetooth hci0: Direct firmware load for brcm/BCM43142A0-0a5c-216c.hcd failed with error -2

Re: [SOLVED] Connect to internet after installation

Check the output of uname -a and of pacman -Q linux
Ensure the versions match.

Does your WiFi show up in the output of lspci -nn   ?
If so, what is the chipset, and what are the VID and PID (The hex digits in the [xxxx:xxxx])?

Re: [SOLVED] Connect to internet after installation

I am not a user of Broadcom devices, but I think you need to install broadcom-wl-dkms.

There are several ways you can do this -- with a wired connection, USB tether a phone, or start from your install media and set up a chroot.
