我有BCM4313 wi-fi模块，该模块在开源brcmsmac模块下可以正常工作，但有许多断开连接和突然故障的情况。
因此，我已经下载了专有的tarball并安装了它，但是不能说它产生了任何影响。
当我通过使用删除所有开源模块时
rmmod brcmsmac bcma
然后将所有专有的插入
modprobe lib80211 cfg80211
insmod /lib/modules/my_kernel/drivers/net/wireless/wl.ko
没有任何反应，我的意思是我的Wicd应用程序未检测到任何可用的连接。
无论如何，我都不是Linux方面的专家，所以我想知道什么是合适的解决方案。

lsmod的输出| 加载我的默认模块时，grep -e brcmsmac -e b43 -e bcma：

自从我最初解决的问题得到解决以来，我的联系一直很好。
但是，今天我重新启动只是为了发现我的连接不再起作用。
首先，我通过使用加载了wl模块
sudo modprobe wl
之后检查了ifconfig并发现eth1 inetrface已关闭并执行
sudo ifconfig eth1 up
提出来
不久之后，使用iwconfig来确保正确检测到eth1
到底打
sudo iwlist eth1 scan
查找所有按计划工作的可用网络
但是，当我最终决定连接并使用它时
sudo iwconfig eth1 essid Network_name (no key option here since this it's not set)
由于没有建立连接，并且iwconfig显示没有访问点与eth1接口相关联，因此引发了故障。
我读了很多手册，但仍然不知道要恢复互联网我需要做什么。
重新安装bcmwl-kernel-source应该会将较差的驱动程序brcmsmac列入黑名单，显然没有。请打开终端并执行以下操作：
gksudo gedit /etc/modules
如果其中有brcmsmac，bcma或b43，请将其删除。添加wl。校对，保存并关闭gedit。现在执行：
gksudo gedit /etc/modprobe.d/blacklist.conf
最后，添加以下行：
blacklist brcmsmac
blacklist bcma
blacklist b43
校对，保存并关闭gedit。重启。查看：
iwconfig
您的无线接口现在是eth1吗？您的连接现在可以正常工作了吗？
