 |
|
Hello, everyone.
After moving to a new location where I only have access to a wireless network, my desktop's wireless card refuses to detect any networks to connect to. The module loads fine, and there are no apparent errors in /var/log/messages. Everything seems normal, except for the fact that no networks are detected. I tried the b43 driver in the 2.6.39 kernel (which is supposed to support the BCM4321 card, according to the page on wireless.kernel.org), and the same thing happens.
ifconfig:
| Code: |

| Actually, brcm80211 is the right driver for that card, and only starting with the 2.6.39 kernel. So try that. Don't forget to install the firmware (sys-kernel/linux-firmware). |

I tried brcmfmac and it gets even worse results. Nothing shows up in ifconfig and the only thing that shows up in /var/log/messages is
| Code: |
brcmfmac: module is from the staging directory, the quality is unknown, you have been warned.

It would be more important to see the kernel log about b43. Do you have the good b43 firmware install for your card?
