从 11.10 升级到 12.04 后没有无线网络

从 11.10 升级到 12.04 后没有无线网络

最后在 Dell 630 Latitude 上升级到 12.04 LTS 并且重启后无线停止工作。

由于互联网速度太慢,我尝试过以各种方式安装 STA、b43 甚至 NDISwrapper,但仍然无法正常工作。我不太懂技术,但我安装过几个 ubuntu 系统,并且无线功能也运行正常,我知道这一定很简单,但我就是看不出来。任何帮助我都会很感激。

答案1

我建议,使用临时可用的互联网连接:

sudo apt-get update
sudo apt-get purge bcmwl-kernel-source
sudo apt-get install linux-firmware-nonfree
sudo modprobe b43

断开临时连接并让我们听到您的结果。
