Edimax EW-7612UAn v2
300Mbps Wireless High-Gain USB Adapter
Review of Linux Compatibility
Edimax EW-7612UAn is a USB WiFi stick, which is available in two different versions,
- both of them using a different chipset and hence needing different drivers.
Version V1: 0bda:8172
The version V1 of the EW-7612UAn bases on the Realtek RTL8191SU chipset
- and has the USB ID: 0bda:8172 :
Bus 001 Device 006: ID 0bda:8172 Realtek Semiconductor Corp. RTL8191SU 802.11n WLAN Adapter
The stick is supported under Linux by the kernel module rtl819x.
- Alternatively, the driver provided by Edimax for download can be used.
- However, this driver has to be compiled and installed by hand.
- EW-7612UAn (USB \ VID_7392 & PID_7612)
Version V2: 7392:7822
The version V2 of the EW-7612UAn bases on the RTL8192CU (RTL8192SU ?) chipset
- and has the USB ID: 7392:7822 :
Bus 001 Device 006: ID 7392:7822 Edimax Technology Co., Ltd
There is no driver integrated in the Linux standard kernel for this stick until now.
- Therefore, one has to download the driver from the Edimax homepage.
The configuration and installation of the driver is explained in detail at blog.
- The following steps have to be executed in order to install the RTL8192 driver:
1. The RTL8192CU(SU) driver package needs to be downloaded:
2. The tools unzip and nano are needed for the installation. These tools can be installed by
apt-get install unzip nano
3. Afterwards, the downloaded archive can be unzipped:
4. and the included archive can be unpacked:
cd RTL8188C_8192C_8192D_USB_linux_v3.4.2_3727.20120404/driver/ tar xfvz rtl8188C_8192C_8192D_usb_linux_v3.4.2_3727.20120404.tar.gz
5. In order to change the souce code files, one should change to the following directory:
6. and has to change the file osdep_service.h
and add after the lines
#include <drv_conf .h> #include <basic_types .h></basic_types></drv_conf>
the following include command:
#include <linux /sched.h></linux>
This means, that the file should look like the following:
#ifndef __OSDEP_SERVICE_H_ #define __OSDEP_SERVICE_H_ #include <drv_conf .h> #include <basic_types .h> #include <linux /sched.h< //#include <rtl871x_byteorder.h></linux></basic_types></drv_conf>
7. Finally, the driver can be compiled and installed
cd .. make clean make sudo make install
8. The compiled kernel module 8192cu can be loaded by
