strangevy 写了：后来尝试下载驱动安装，好像也不成功

若已执行过 sudo make install，执行 sudo make uninstall 将其移除

尝试安装修改版驱动 https://github.com/Mange/rtl8192eu-linux-driver
如遇到困难将相关的输出全部复制贴上来

你的无线网卡是什么？
TP-LINK TL-WN821N V5 ？

无线网卡驱动确实是令人懊恼的事情

尝试安装修改版驱动 https://github.com/Mange/rtl8192eu-linux-driver

这个驱动安装成功！
# modprobe lib80211
# modprobe cfg80211
# insmod 8192eu.ko
之后可以连接上wifi，但是重启后又没有。
重新执行
root@strangevy-ubuntu:~/文档/rtl8192eu-linux-driver-master# insmod 8192eu.ko
insmod: ERROR: could not insert module 8192eu.ko: File exists
也不行了

这个驱动安装成功！
# modprobe lib80211
# modprobe cfg80211
# insmod 8192eu.ko
之后可以连接上wifi，但是重启后又没有。

gksudo gedit /etc/modules
在 /etc/modules
加上這三行
lib80211
cfg80211
8192eu.ko （或 8192eu）
重開機

補充
1. modprobe / insmod 單次載入
/etc/modules 每次開機即載入
2. 第一次使用 gksudo 需要先安裝 gksu 套件

加入8192eu就搞定了，thx
