First install and wireless network (BCM43142)

messenja · 2014-11-22 20:30:38

Hi guys.
Im newbe on it. And sorry for my bad eng =/
I havent ethernet on my laptop, wi-fi only. And i need to install arch (from my USB stick). After system is loaded my lspci -k looks like:
...
04:00.0 Network controller: Broadcom Corporation BCM43142 802.11b/g/n (rev 01)
Subsystem: Lenovo Device 0611
Kernel driver in use: bcma-pci-bridge
Kernel modules: bcma

In ip link command there is no wlan(wlp etc..) interfaces. I have red archwiki and other topics about broadcom wireless, tried to load wl but it seems that there is no wl module in booted system. So how can i configure wi-fi to start installing my base arch system on my laptop?

Thank you.

Can you please post the chipset info from lspci with the following command:

lspci -vnn | grep -i net

EDIT: The above command would get the PCI ID which I find more useful, but it seems the chip ID in your title may unambiguously identify this chip as 14e4:4365. If you see that string of numbers in square brackets in the output of the command above, that would confirm this - and in that case I concur with Gusar's point below. However, some users have compiled the wl package from the AUR on another computer (perhaps in a VM) and transferred the built package to the machine they wish to install to. This is a possibility, but it is a bit involved if you are brand new to archlinux.

Basically, you can't. broadcom-wl is a proprietary driver, that's why it's not part of the install media. The simplest option is getting an usb adapter that is supported, something with an Atheros or Realtek chipset. Use that to install Arch, then compile broadcom-wl in the installed system.

You don't need a usb wireless card: you can either download/compile the package on another computer, or download it on another computer and compile it from the installation medium. The "other computer" in question could be a virtualbox virtual machine running the installation iso of arch linux, in which case downloading/compiling broadcom-wl would be as simple as running "makepkg". (See wiki article on AUR)

Yes, lspci -vnn | grep -i net says:
...
04:00.0 Network controller [0200]: Broadcom Corporation BCM43142 802.11b/g/n [14e4:4365] (rev 01)
When i said that i havent ethernet i meant that i havent wired network. Ethernet interface is present (my lspci command above is not full). Will find wired network to install the base system. Thank you guys for replies.

Downloading beforehand is quite tricky, there's quite a few packages required for the compile chain. But running the install medium in VirtualBox or a second machine could work. The problem in both cases is, does the linux-headers package in the repository match the kernel on the install medium. One could use the Arch Rollback Machine to get the right package, but no idea if someone new to Arch would be capable of handling all that. Using an usb adapter is much, much simpler.

Another way to get the packages is

# pacman -Sp pkgname --print-format "%l" > pkglist.txt

Later pass the pkglist.txt to aria2c, available for windows too. Then the packages should be moved to pacman cache or to tell pacman where the packages are during the installation.

It's quite weird because a driver seems to has been launched but nothing appears for ip link show:

ip link show

    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

P.S. : for further reference, it's a part of the always same history.

Try to install the broadcom-wl driver (yaourt).

Well, it's restrictively licensed then it's not free. I'd like to keep being free :-) but if I have no choice, yes, I may do this.
