我刚买了一台新电脑（联想 G580），安装了 Ubuntu 13.04。我无法通过 Wi-Fi 连接，只能通过电缆连接。
我尝试了几个网络（我自己的和邻居的），但都没有成功，然后奇怪的事情发生了：当我用我的 Android 设备创建热点时，我能够连接到互联网。我有点困惑！
有人知道可能发生什么事或如何解决吗？
也许这些数据是有用的：
02:00.0 Ethernet controller [0200]: Qualcomm Atheros AR8162 Fast Ethernet [1969:1090] (rev 10)
03:00.0 Network controller [0280]: Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller [14e4:4727] (rev 01)
如果您需要任何进一步的数据，请询问，我会尽快回答。
PD：在安装 Ubuntu 13.04 之前，我使用的是一台装有 Ubuntu 12.04 的旧电脑，WiFi 运行良好。
PD2：我尝试了几种 WiFi 连接，包括我自己的和 3 个邻居的，但我们都使用同一个 ISP。
编辑：
连接到 Android 热点时运行“grep NetworkManager /var/log/syslog | tail -30”的结果：

答案1
在 Lenovo G580 上运行以下命令对我有用：
sudo apt-get install build-essential linux-headers-generic linux-headers-`uname -r`
wget -O- http://linuxwireless.org/download/compat-wireless-2.6/compat-wireless-2012-07-03-pc.tar.bz2 | tar -xj
cd compat-wireless-2012-07-03-pc
./scripts/driver-select alx
make
sudo make install
答案2
同样的问题。Android 热点没有任何安全性，所以我将家用无线路由器改为非加密，现在我的笔记本电脑就可以正常工作了！！！
我采纳了 Daniel Yuste Aroca 的建议，发现 DHCP 存在问题。因此，我为笔记本电脑分配了一个静态 IP 地址，现在它可以在启用安全的情况下工作。
因此看起来 DHCP 在启用安全性的情况下无法工作。
我还尝试了另一个用户的建议，禁用了专有驱动程序。它在启用 DHCP 和安全性的情况下工作。
对我来说，这是一个小总结： - 专有驱动程序：它适用于 DHCP 和无安全性，或静态 IP 和启用安全性 - Ubuntu 驱动程序：它适用于 DHCP 和启用安全性

答案3
尝试禁用第三方驱动程序。对我来说，这个方法有效。Piotr
