Even I had same problem and fixed it. Try the code below one by one in terminal having the adapter connected. You can see changes in terminal after each code.
sudo apt-get update sudo apt-get install linux-headers-$(uname -r) build-essential git git clone https://github.com/lwfinger/rtl8188eu cd rtl8188eu make all sudo make install sudo insmod 8188eu.ko
