Hi,

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 
| Code: |
07:00.0 Network controller: Broadcom Corporation BCM43142 802.11b/g/n (rev 01)
Subsystem: Dell Wireless 1704 802.11n + BT 4.0

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.
