Problem - TL-WN722N v2.0

Wed Mar 22, 2017 2:47 pm

Hi there !

I have a TL-WN722N v1.10 that works out of the box with my Raspberry Pi 3 and I recently bought a second one (a 2.0 version) that doesn't at all..

I searched a lot on the Internet, but I don't find any solution...

I use this image of Raspbian : 2017-03-02-raspbian-jessie
My kernel version ("uname -a" command) :

Code: Select all

Linux raspberrypi 4.4.50-v7+ #970 SMP Mon Feb 20 19:18:29 GMT 2017 armv7l GNU/Linux
"lsusb" command with the v2.0 adapter gives me :

Code: Select all

Bus 001 Device 004: ID 2357:010c  
Bus 001 Device 006: ID 1a2c:0c21 China Resource Semico Co., Ltd 
Bus 001 Device 005: ID 046d:c52b Logitech, Inc. Unifying Receiver
Bus 001 Device 003: ID 0424:ec00 Standard Microsystems Corp. SMSC9512/9514 Fast Ethernet Adapter
Bus 001 Device 002: ID 0424:9514 Standard Microsystems Corp. 
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
whereas "lsusb" command with the v1.10 adapter gives me :

Code: Select all

Bus 001 Device 007: ID 0cf3:9271 Atheros Communications, Inc. AR9271 802.11n
Bus 001 Device 006: ID 1a2c:0c21 China Resource Semico Co., Ltd 
Bus 001 Device 005: ID 046d:c52b Logitech, Inc. Unifying Receiver
Bus 001 Device 003: ID 0424:ec00 Standard Microsystems Corp. SMSC9512/9514 Fast Ethernet Adapter
Bus 001 Device 002: ID 0424:9514 Standard Microsystems Corp. 
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
I think I don't have the right firmware for the v2.0, but I can't find how to install it, even after hours of try... I guess I don't do it right relative to my kernel version, but I can't find...

I hope someone has a solution... ;)

Thanks a lot. Best regards.

Hey there,

i have exactly the same problem. Nothing will work.
Also by tryint to compile the kernel module founded at:

http://www.tp-link.de/download/TL-WN722N.html

TL-WN722N(EU)_V2_161112_Linux for Kernel 2.6.18~3.19.3

Hopefully there is anyone who solved this problem

Having the same problem... Bought the same adapter yesterday and still can't make it work with kali linux.

Code: Select all

 usb_modeswitch -v 2357 -p 010c 


gives that manufacturer is Realtek with s/n: 00E04C0001... The chipset was Atheros previously, but now it's Realtek. Worked with ath9k_htc drivers previously, but now i guess some rtl???? are needed...

It looks like TL-WN722N uses Realtek chipset RTL8188EUS (https://apps.fcc.gov/eas/GetApplication ... id=3260166). And it's such pain in the ass to find and compile drivers for Linux... If somebody wants to try here are the drivers and the manual for older kernel (http://www.mediafire.com/file/6fudhr4fm ... 188EUS.zip). Good luck! It's surely not impossible, but too much for me atm. I guess I'm simply going to return my adapter tomorrow morning.

Hi,
I too bought the WN722N after seeing on forums that it should work, not realising that the v2 is a different chipset. After a bit of searching I found that the rtl8188eu driver from lwfinger supports this device. I'm not an expert but I managed to compile it and it works:
(TL-WN722N v2.0 USB ID 2357:010c, Rasbian Jessie 4.4.50-v7+ #970)

Download the driver source zip from
http://github.com/lwfinger/rtl8188eu

Unzip it and move the rtl8188eu-master directory somewhere like /home/pi/rtl8188eu-master

Make sure the Linux headers are installed:

Code: Select all

sudo apt-get install raspberrypi-kernel-headers
(this can take a few minutes to complete).
Create the symbolic link to the headers:

Code: Select all

sudo ln -s /usr/src/linux-headers-$(uname -r) /lib/modules/$(uname -r)/build
Compile and install the driver:

Code: Select all

cd /home/pi/rtl8188eu-master
make all
sudo make install
If necessary configure the wireless LAN using /etc/network/interfaces as described elsewhere, e.g.: viewtopic.php?t=52616
Reboot.

For anyone buying wireless adapters, it is common to find different chips in each version and, sometimes, different chips in each batch or shipments to different countries. Finding the USB chip id line in lsusb is the only reliable way of identifying the chip.

Please try the following solution by MrEngMan - works flawlessly simple to use

First it would be a good idea to fix your internet connection so you can download without problems.

The simplest way to install my wifi drivers is to use my install-wifi script which determine the wifi adapter you use and the kernel version you have and then should automatically download and install the right version of the driver. You can download and install the script using commands

sudo wget http://fars-robotics.net/install-wifi -O /usr/bin/install-wifi
sudo chmod +x /usr/bin/install-wifi

After it is installed run the following

sudo install-wifi

driver should be instantly installed. works for mostly realtek drivers

kashyapgada instructions worked flawlessly on my Pi Zero.

Thanks a lot for getting my TL-WN722N Wi-Fi adapter up and running.
