[SOLVED] Realtek network adapter works on live USB, but not on install

During installation, wifi was easy to set up using netctl. But after booting into the newly installed system, there seem to be some issues.

I have the Realtek RTL8822BE adapter, which I thought was natively supported by the kernel. lspci -k shows that it uses the kernel driver rtwpci.

dmesg | grep rtw gives the following output:

rtw_pci 0000:02:00.0: Direct firmware load for rtw88/rtw8822b_fw.bin failed with error -2
rtw_pci 0000:02:00.0: failed to request firmware
rtw_pci 0000:02:00.0: failed to load firmware
rtw_pci 0000:02:00.0: failed to setup chip efuse info
rtw_pci 0000:02:00.0: failed to setup chip information
rtw_pci: probe of 0000:02:00.0 failed with error -22

Any help would be greatly appreciated!

Which command did you pass to pacstrap? https://www.archlinux.org/news/base-gro … -required/

You will likely need to install linux-firmware (it's only optional because there are systems where it isn't required)

Welcome to Arch Linux.

Most likely you forgot to install the linux-firmware package. Then you'll have to choose and install your network manager as well. Also check if you need some of the optional dependencies when installing a package (e.g. wpa_supplicant for netctl).

Thank you both so much! Can't believe it was so simple.
