I recently installed Archlinux on my laptop, and as per the instructions on the Arch Wiki (https://wiki.archlinux.org/index.php/Wireless_network_configuration#Check_the_driver_status) I checked the output of the 'lspci -k' command.

The sample output from the wiki is like this:

06:00.0 Network controller: Intel Corporation WiFi Link 5100
    Subsystem: Intel Corporation WiFi Link 5100 AGN
    Kernel driver in use: iwlwifi
    Kernel modules: iwlwifi

When I run the command, my output is this:

03:00.0 Network controller: Broadcom Corporation BCM4352 802.11ac Wireless Network Adapter (rev 03)
    Subsystem: AzureWave Device 2123

I noticed that the 'Kernel driver in use' and 'kernel modules' fields are not displayed. Being new to the OS, I have no idea what that means or what to do about it.

How do I get the kernel to 'use' my wireless adapter? If it matters, I'm booting the OS from a USB drive.

Seems like Broadcom devices have a weird history with respect to Arch Linux.

I found this Arch Linux wiki article which seems to be your question exactly. The salient advice given is this:

Install broadcom-wl from aur, unload the brcmsmac and load the wl module.

That AUR package is here. Oddly, the Broadcom page referenced from the AUR page doesn't claim that is supports BCM4352, but quite a few other Arch forum pages say that the broadcom-wl package both works and doesn't work.

  • Would you elaborate on how I install it? I can't download it on Linux without an internet connection and I don't know how to transfer it from my downloads folder in Windows.

  • @TheDerkus - I've never set up or used a dual boot machine, and I only use Windows at work. I would guess that you could mount the Windows disk when you've booted from a USB drive, but I don't know for sure. That's really another question. Jun 22 '15 at 0:49
