TP-link WN725N nano usb driver installation problem

[TWPonKubuntu]

I have a newly purchased TP-Link device (11/20/13), model TP-link WN725N nano usb
I cannot determine from the supplied documentation whether this uses the Realtek ver. 1 or ver. 2 chip.

This is the data I have collected:

System Kubuntu 13.04 - current as of this date.
Kernal: 3.8.0-33-51-generic

lsusb:
Bus 001 Device 005: ID 0bda:8179 Realtek Semiconductor Corp.

I compiled and loaded the driver for the 8188eu, from this link:

https://github.com/lwfinger/rtl8188e...ive/master.zip

The driver successfully installed and I can now see the following from iwconfig:

wlan0 IEEE 802.11bg ESSID:"public-wc"
Mode:Managed Frequency:2.437 GHz Access Point: 00:0B:0E:E8:41:00
Bit Rate=54 Mb/s Tx-Power=20 dBm

wlan2 unassociated Nickname:"<WIFI@REALTEK>"

Retryff RTS thrff Fragment thrff
Power Managementff
Link Quality:0 Signal level:0 Noise level:0
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0

lo no wireless extensions.

eth0 no wireless extensions.

The device (wlan2) is visible to the WLAN interface utility under Kubuntu 13.04, but no access points are found.
As you see from the iwconfig data, my original b43 wifi (wlan0) is installed and it does find multiple access points.

wlan2 displays this data on the WLAN interface utility:

Type: Wireless 802.11
Connection State: Unavailable
IP Address: No IP address.
Connection Speed: Unknown
System Name: wlan2
MAC Address: 64:66:B3:21:76:FD
Driver: r8188eu

Does anyone have some advice on how to get this device to work on my system? Thanks

You also might need to kill the first connection before network manager will allow a second one. network manager is a huge PITA IMO.

Well... Been there, done that, which is what got me to Larry Fingers github code.
I've also gone through these:
http://www.realtek.com.tw/default.aspx
http://wikidevi.com/wiki/TP-LINK_TL-WN725N_v2
https://help.ubuntu.com/community/Ha...rkCardsTP-Link
http://wireless.kernel.org/en/users/Drivers/rtl819x
There were other *buntu links of various flavors, but the code was just sufficiently unlike Kubuntu/ubuntu that they failed.
I don't use Google directly, not a very safe/private tool, however I do get google results via proxy access.

I did that, disabled the wlan0 connection, without effect on the Realtek connection.
My experience is that I can run two or more wifi connections, simultaneously, just not this particular one.
The primary, the b43 chipset on wlan0, is a desktop internal card with antenna.
The secondary is the usb dongle, wlan2, and I'm not sure how to configure it to become "associated" for operation. That term, "associate", doesn't mean enough to suggest what action to take here.

Additional info. I did blacklist these drivers, per the instructions from Larry Fingers driver.
# Blacklist native RealTek 8188CUs drivers
blacklist rtl8192cu
blacklist rtl8192c_common
blacklist rtlwifi

SOLVED:

This is the process:

From this page:

http://www.ubuntuask.com/q/answers-t...-o-377470.html

The instructions set which worked for Kubuntu 13.04 is as follows:

Download this zip and "extract here" using Ark (or utility of your choice) into your home directory:

https://github.com/lwfinger/rtl8188e...ive/master.zip

This will create a set of directories in /home/your-name/rtl8188eu-master
From your home directory, execute:

cd rtl8188eu-master
sudo make
sudo make install
sudo modprobe 8188eu

The driver should now be active and visible to NetworkManager

A quick addendum, I've moved to Kubuntu 14.04 and the process for installation of the Realtek ttlink wireless adapter worked perfectly, per my previous posting...
