更新到 16.04 后，我的 Wifi 卡不再工作了。我不知道该怎么办。

答案1
我在从 15.10 升级到 16.04 时遇到了同样的问题。我按照其他人的建议解决了这个问题，具体如下：
- 如何安装 wifi 驱动程序 Ralink RT3290和以下第二个答案，第 1 至第 8 步，位于文章的中间位置
我必须通过打开终端窗口并发出以下两个命令来启用我的无线网卡：
sudo ifconfig eno1 up和
sudo service network-manager restart
eno1 是我的无线网卡的逻辑名称（在sudo lshw -C network命令输出中找到）。
您可以通过将步骤 2 中的两个命令添加到 /etc/rc.local 来自动执行它们（请参阅我怎样才能让“rc.local”在启动时运行？我可以让“rc.local”在启动时运行吗？
答案2
将我的笔记本电脑从 14.04 升级到 16.04 后，我的 RT3090 无线网卡也遇到了同样的问题。
经过一番折腾之后，我发现 Wifi 只有在从挂起状态恢复后才能工作。
我最终似乎通过在文件中添加以下内容解决了该问题/etc/rc.local：
sudo ifconfig wlan0 up
sudo service network-manager restart
如果您的设备不是“wlan0”，您可以根据需要替换。
答案3
我通过安装这个驱动程序修复了这个问题：
