 |
|
Hi,
few month ago i used wireless on my notebook without problems. I have a BCM43225 card, and installed the relative firmware (sys-firmware/b43-firmware and net-wireless/b43-fwcutter ), also the kernel module build-in.
Few month ago worked perfectly, now i can't see the card, ifconfig and iwconfig don't see it.
Have you any idea how to solve?
Thank you

A good start would be your output of lspci -k.
Also https://wiki.gentoo.org/wiki/Wifi might be of help for you. |

Something similar happened to me a month ago, after updating the kernel:
The kernel wasn't getting the firmware from userspace anymore. I ended up adding the firmware to the kernel build:
| Code: | CONFIG_EXTRA_FIRMWARE="iwlwifi-6000g2a-6.ucode"
CONFIG_EXTRA_FIRMWARE_DIR="/lib/firmware"
|
(check the firmware name in /lib/firmware).
If your dmesg complains about not finding the firmware, this could be it. |

dmesg | grep firmware

Now i try with your configuration for loading extra firmware. |

I have a subdir "b43" under /lib/firmware, which contains several file *.fw
What files i have to include in that kernel configuration?
And why it is needed? Bug in loading firmware? |

ok, with kernel 3.14 it works...
Now, if i use networkmanager with nm-applet, wireless works perfectly, but iwconfig doesn't work..

# iwlist wlp2s0 s
wlp2s0 Interface doesn't support scanning.

Have you any idea? |
