brcmsmac/brcmfmac
The brcm80211 drivers have been included in the kernel since 2.6.37. Since the release of 2.6.39, they have been renamed to brcmsmac (for PCI cards) and brcmfmac (for SDIO).
These drivers should be automatically loaded during startup and no further action should be required of the user.
At the time of writing, there are three choices for users with Broadcom Wi-Fi chipsets:
brcmsmac/brcmfmac
b43
broadcom-wl
无线网卡驱动现在没一个统一的驱动标准, Broadcom Wi-Fi 有三种驱动选择
brcmsmac/brcmfmac
b43
broadcom-wl
按照文章提示,你还需要移除多余的驱动,因为你用的是第三种,MGC 已经安装了第二种驱动,但愿你自己能解决这个问题,然后把方案说道说道。
