看了别人的ＢＢＳ，自己没有搞店。

Linux 3.19.0-37-generic

安装较新的内核

authentication with xx:xx:xx:xx:xx:xx timed out
driver=rtl8188ee

先尝试 lwfinger 维护的 rtlwifi 驱动：https://github.com/lwfinger/rtlwifi_new
下载 zip，解压，make，sudo make install

或者直接使用PPA (rtlwifi-new-dkms 0.6~trusty)：https://launchpad.net/~hanipouspilot/+a ... tu/rtlwifi

补充一些资料，大家好帮助我分析问题！

已经按这个方法安装成功，如何应用rtl8188ee驱动？

已经按这个方法安装成功，如何应用rtl8188ee驱动？

如果采用手动编译法，sudo make install 过程中会自动为已有驱动创建备份(./backup_drivers.tar)，自动替换内核自带的 rtl8188ee，并自动启用。（编译出的模块名字与内核自带的一样，都是'rtl8188ee.ko'。）

现在使用了 dkms 法，只能假设 其已自动替代内核自带的 rtl8188ee，并已自动启用。

到 /lib/modules/`uname -r`/kernel/drivers/net/wireless/ 中找 rtl8188ee.ko，看修改时间是否为刚才。
