sudo apt-get install git dkms git make build-essential
cd /usr/src
sudo git clone https://github.com/lwfinger/rtl8188eu.git
sudo dkms add ./rtl8188eu
sudo dkms build 8188eu/1.0
sudo dkms install 8188eu/1.0

Hi, thanks for your instruction and I have a question about how to match the kernel version.
I am running 16.04, with an older kernel (my $(uname -r) returns "3.10.107-190").
So when I run step #8, it complains that I don't have linux-headers-3.10.107-190.
Could you please tell me how do I solve this problem?

Hi, thanks for your help. But when I try last step, sudo modprobe 8188eu, i get the following message: 'modprobe: ERROR: could not insert '8188eu': Device or resource busy'. How to solve it? Thank you

This is just a copy-paste gist for the code that can be found at askubuntu.com, check the link.

@weiminshen99

it complains that I don't have linux-headers-3.10.107-190

Just try sudo apt-get install linux-headers-3.10.107-190 or linux-headers-generic.
Searching can be done this way: apt-cache search linux-headers

Check out this answer: https://unix.stackexchange.com/a/246881

Copy/paste - worked perfectly! Thanks!

Works great Thanx!!!

Yes, it worked! Even in several computers, no problems at all. You just need to plug it out and stick it in again when you get this error: 'modprobe: ERROR: could not insert '8188eu', repeating the command 'sudo modprobe 8188eu'. Perfect. Thank you so much

If you get 'modprobe: ERROR: could not insert '8188eu', you can get the current driver module name by typing sudo lshw -C network (source: https://askubuntu.com/a/333430) then removing it with sudo modprobe -r currentDriverName (source: https://unix.stackexchange.com/a/246881) and finally sudo modprobe 8188eu
