|
|
Hi, I've got a BCM4322 802.11a/b/g/n wireless on a Dell vostro 1320 , it worked fine with broadcom-sta and wicd untill two or three months ago than I made 1 or 2 kernel update but I didn't used the wireless in this period. Now I need wireless again but it doesn't work.
wicd scan (very fast) for wireless but didn't find anything (I know for sure there' one wireless ready and working)
this is my emerge --info:

This is not a solution, but it does provide insight into the problem:
http://pof.eslack.org/2012/05/23/why-broadcom-80211-linux-sta-driver-sucks-and-how-to-fix-it/
(Ubuntu patches, and the discussion refers to wext and cfg80211 as
alternatives, while on my system the kernel has cfg80211, mac80211,
*and* wext options enabled, and wpa_supplicant uses the "-Dwext" driver
without issues with different kinds of wifi hardware drivers enabled
in the kernel. So the idea that wext and cfg80211 are different ways
of doing the same thing is perhaps obsolete. They seem to function
more as complementary parts of wifi hardware management by
the kernel on newer kernels.) _________________ TIA |

-Dwext only works with newer drivers because cfg80211 has a wext compatibility module (CONFIG_CFG80211_WEXT). But their approach to configuring the hardware is quite different: wext uses ioctl, cfg80211 uses netlink.
BCM4322 is supported by the b43 driver. That's a much better option than the closed-source wl driver. |

A question: if I disable
in the kernel, will the wpa_supplicant -Dwext driver cease to work
with mac80211 kernel wifi hardware drivers? _________________ TIA |

Yes. You'll have to use -Dnl80211 instead. |

Ok, thanks for the info (I didn't mean to hijack the thread,
but in the interests of clarity, ....) _________________ TIA |
