wlan0 not found during installation

Hi,

I am stuck at the wifi configuration process during installation. USB is in my laptop with the iso but my wifi device cannot be found.

`ip link`:
only shows lo and enp9s0

`lspci -v` shows Network controller to be Broadcom BCM4312 with kernel driver in use: b43-pci-bridge and kernel modules as ssb.

ls /proc/sys/net/ipv4/conf says `all default enp9s0 lo`

`lsmod | grep wifi` doesnt return any thing.

`iwctl device list` is empty

`uname -a` gives Linux archiso 6.1.10-arch1-1.0 .....

Laptop is a 32-bit Dell Latitude whose wifi works just fine on a windows 7 installation. How do I get my wifi to work. Can anyone help me?

Re: wlan0 not found during installation

You might miss the firmware for the Broadcom Wifi. It's always easier to install without wireless and then add the corresponding firmware to the installed system.

You can also try to find the corresponding firmware package and install it into the live ISO environment.

Re: wlan0 not found during installation

The broadcom-wl package claims to contain a driver for the Broadcom 802.11 Linux STA wireless driver, whether that's suitable for a BCM4312 I couldn't say.

You can either download the package on another machine or the same machine and presumably put it on the USB stick in addition to the ISO, or find a short network cable and plug the laptop directly into the router so you can install it using pacman.


Architecture: pentium4, Testing repos: Yes, Hardware: EeePC 901+2GB RAM+OS half on the SD card.
