我最近安装了 Ubuntu 16.04 和 Windows 10,我是 Linux 新手。我有一台联想 Ideapad 500,16 GB RAM,AMD FX 8800。
安装 Ubuntu 后,wifi 无法使用,我找到了一个解决方案,你必须在新目录中安装驱动程序(我认为是这)。
所以我的 wifi 现在可以使用了,但问题是连接速度比 Windows 10 慢,下载速度也更慢,我通过 speedtest.net 确认了这一点(在 Windows 上我得到 4-7 Mbps,在 Ubuntu 上我得到 ~0.5 Mbps)。我尝试了一种解决方案,你必须在驱动程序文件中添加 nohwcrypt 命令(我认为),然后此解决方案。但是不起作用,网络仍然很慢。这是输出sudo lshw -C network
