Broadcom BCM4321 找不到网络

Broadcom BCM4321 找不到网络

我花了几个小时尝试让我的 wifi 卡工作。我将 PCI 卡从一台正常工作的机器移到另一台新机器。两台机器都运行 Ubuntu 12.04。该卡在第一台机器上运行良好,但现在无法找到任何无线网络。我正在使用司机被告知要与BCM4321芯片组。我使用此页面作为安装指南:https://help.ubuntu.com/community/WifiDocs/Driver/bcm43xx#A12.04_.28Precise_Pangolin.29_-12.10.28Quantal_Quetzal.29

我希望有人能提供建议来帮助我摆脱痛苦:)详情如下。

dmesg(BCM4329看起来很可疑,因为芯片组应该是BCM4321):

lspci:

配置:

lshw(是驱动程序=wl0好的?):

root@mymachine:/# lshw -C network

lsmod(驱动程序实际上并不与内核通信,对吗?):

root@mymachine:/# lsmod | grep wl
wl                   3074978  0
cfg80211              499466  1 wl
lib80211               14381  2 wl,lib80211_crypt_tkip

我对 /etc/modprobe.d/blacklist.conf 所做的更改(添加了最后 3 个):

# replaced by b43 and ssb.
blacklist bcm43xx
blacklist brcmsmac
blacklist bcma
blacklist b43

iwlist扫描:

root@mymachine:/# iwlist eth1 scanning
eth1      No scan results

您有 3 种可能的解决方案

  • 使用以太网(将电缆连接到路由器和电脑),然后转到设置管理器->附加驱动程序并查找使用 Broacom 驱动程序的位置(类似的东西)
  • 如果您没有找到该驱动程序。然后执行此解决方案sudo nano /etc/modprobe.d/blacklist.conf,然后添加blacklist b43并从黑名单中删除 brcmsmac。然后转到sudo nano /etc/modules并添加wlbrcmsmac。后者在我的 PC 上运行良好。我也有 Broadcom,但不是同一个。
  • 如果这些解决方案都不起作用,则升级到 Ubuntu 13.10,使用以太网连接到互联网,然后转到其他驱动程序,您肯定会找到 Broadcom 驱动程序。
