Hi,

Code:

# lspci -k

07:00.0 Network controller: Broadcom Corporation BCM43142 802.11b/g/n (rev 01)
   Subsystem: Dell Wireless 1704 802.11n + BT 4.0
   Kernel driver in use: bcma-pci-bridge
   Kernel modules: wl

Code:

# iwconfig
enp9s0    no wireless extensions.

sit0      no wireless extensions.

lo        no wireless extensions.


My wireless card works with broadcom-wl-dkms in Arch.
With Gentoo, I emerged broadcom-sta and I blacklisted following :

Code:

blacklist bcma-pci-bridge
blacklist bcma
blacklist b43
blacklist ssb


wl is loaded, but still interface is not detected.
Code:

# Module                  Size  Used by
wl                     6265123  0
x86_pkg_temp_thermal     4535  0


Any ideas ?

I got this info from this page. Try emerging b43-fwcutter and then running the following:

Code:
wget -q -O- http://www.lwfinger.com/b43-firmware/broadcom-wl-5.100.138.tar.bz2 | tar jx
b43-fwcutter -w /lib/firmware broadcom-wl-5.100.138/linux/wl_apsta.o

That didn't work :(

Sorry, I misread the model number. Do you have the following options in your kernel config?

Code:

Processor type and features  --->
    Preemption model  ---->
        <Choose something other than Preemptible Kernel (Low-latency desktop)>
[*] Networking Support  ---->
    [*] Wireless  ---->
        <  > cfg80211 - wireless configuration API
Device Drivers  ---->
    [*] Network device support  ---->
        [*] Wireless LAN  ---->
            <M> IEEE 802.11 for Host AP (Prism2/2.5/3 and WEP/TKIP/CCMP)

Make sure you are using the latest version (echo net-wireless/broadcom-sta >> /etc/portage/package.accept_keywords; emerge -1u broadcom-sta). If that doesn't work, maybe try ndiswrapper? ... or submit a bug.

I also noticed there are net-wireless/broadcom-firmware-downloader and net-wireless/broadcom-firmware-installer packages under the Pentoo overlay. Maybe these would help as well?

Which kernel?
Wireless stopped working updated to gentoo-sources-3.17.8-r1.
Works with 3.10.14.
