我刚刚在联想 B590 上安装了 ubuntu。我的问题是我可以通过 wifi 连接我的笔记本电脑，但我没有互联网连接。
我找到了一些技巧，比如关闭 IPV6，但不起作用。我已经完成了所有的 apt upgrade 和 apt update。
所以现在我已连接以太网线，并且已关闭我的 wifi 以便上网并发布我的问题。
以下是有关我的设置的一些信息：

你们其中一人告诉我这是关于两个司机之间的冲突，所以我按照指示去做了
sudo -i
echo "blacklist b43" >> /etc/modprobe.d/blacklist.conf
echo "blacklist ssb" >> /etc/modprobe.d/blacklist.conf
exit
这就是结果

答案1
尝试通过 apt 安装此包 firmware-brcm80211 或者您可以尝试通过附加驱动程序安装它（此处有描述性过程：http://www.psychocats.net/ubuntu/drivers）
顺便说一下，只需按下超级键（Windows 键），然后输入“附加驱动程序”并按照指导的程序操作，就可以解决问题。
答案2
尝试使用以下命令重新启动网络管理器：，service network-manager restart
然后使用以下命令在终端中进行测试：ping www.google.com
答案3
我们在您的粘贴中注意到了这一点：
b43 413696 0
mac80211 778240 2 b43,brcmsmac
cfg80211 622592 3 b43,mac80211,brcmsmac
ssb 57344 1 b43
有两个相互冲突的驱动程序争夺无线控制权。我认为正确的驱动程序是韓國。让我们将其他人列入黑名单。从终端：
sudo -i
echo "blacklist b43" >> /etc/modprobe.d/blacklist.conf
echo "blacklist ssb" >> /etc/modprobe.d/blacklist.conf
exit
重新启动并让我们听到结果。
