2. Computer B (Other Wireless) IP: 192.168.1.26/29

Ubuntu Linux TP-Link TL-WN723N Driver

Update

The more recent driver for TP-Link TL-WN723N can be found on https://github.com/lwfinger/rtl8188eu. This new driver address problem for kernel 3.8+. Do not forget to copy the firmware file rtl8188eufw.bin to /lib/firmware/rtlwifi/. Failed to do so, you might can not bring the device up.

 

I just bought a nano wireless adapter from TP-Link, the TL-WN723N. But my Xubuntu 12.04 did not recognize it, well that sucks. But thanks to this guy he made the driver for it: https://github.com/gleb-chipiga/rtl8188eu.

Driver Installation

Make sure the compiler and git already installed on the system.

$ mkdir -p /tmp/tp-link && cd /tmp/tp-link
$ git clone https://github.com/gleb-chipiga/rtl8188eu
$ cd rtl8188eu
$ make
$ CURRENT_KERNEL=$( uname -r )
$ sudo cp 8188eu.ko /lib/modules/$CURRENT_KERNEL/kernel/drivers/net/wireless/
$ sudo depmod -a
$ sudo modprobe 8188eu
$ ip link show

The wireless adapter should be detected, no need to reboot.
