How to get the tp-link TL-WN723N working on ubuntu?

Look in the Windows drivers cd:

/media/CD176A1/TL-WN725N_WN723N/Driver Files/Windows 7 32bit

for the file netrtwlanu.inf search for RTL8188EU. If you have that do this:

add other drivers on blacklist sudo gedit /etc/modprobe.d/blacklist

# Blacklist native RealTek 8188CUs drivers
blacklist rtl8192cu
blacklist rtl8192c_common
blacklist rtlwifi

Go here https://github.com/lwfinger/rtl8188eu

Get the zip from Download this repository as a zip then:

then:

cd ~/Downloads/
unzip rtl8188eu-master.zip -x
cd rtl8188eu-master/

then do the steps from README.md:

make
uname -r 

in my case 3.2.0-43-generic-pae so I use

sudo cp 8188eu.ko /lib/modules/3.2.0-43-generic-pae/kernel/net/wireless/
sudo depmod -a
sudo modprobe 8188eu
ifconfig # and you can see the wlan interface :-)

if it is not RTL8188EU look in that file and write here as a comment the RTL8... you find there
