1. Release Note
1.1

Revision History

Refer to /VT665x_Linux_src_v1.1x_x86/codechangeindex.txt file.

1.2

Function

Refer to /VT665x_Linux_src_v1.1x_x86/codechangeindex.txt file.

2. Features
This user manual is applied for VNT6655GMA00, VNT6655GCV00, VNT6655GPV00,
VNT6656GEV00, VNT6656GUA00, VNT6656GUV00, VNT6656G6A10 and VNT6656G
6A40 series models.
This source code package can be use in Linux version :
Refer to /VT665x_Linux_src_v1.1x_x86/linux.txt file.

2.2

Contents of the Subdirectory

Refer to /VT665x_Linux_src_v1.1x_x86/linux.txt file.

3. Compile and Install driver
Notice: here, I compile and install VT6655_linux_src_v1.18.05_x86, please use your driver
replace it and if you use VT6656 do this, please use vntwusb.ko replace viawget.ko that
appearing in the guide.
Open the computer and run Linux operating system, you must do all the steps here as the
root user. Please make sure your root login. By the way , make sure you have installed
essential compilation tools , build-essential and linux-headers-xxxx.
First, copy the driver package to your directory. Here, I copy the driver to /home directory.
Enter your directory.
cd /home
Then, we unpack the driver source code and openssl-0.9.8a
unzip VT6655_Linux_src_v1.18.05_x86.zip
cd VT6655_Linux_src_v1.18.05_x86/wpa_supplicant
unzip openssl-0.9.8a.zip

3.1 Compile the driver
cd /home/ VT6655_Linux_src_v1.18.05_x86
make clean
make install
cd /home/ VT6655_Linux_src_v1.18.05_x86/wpa_supplicant/openssl-0.9.8a
make install
cd /home/ VT6655_Linux_src_v1.18.05_x86/ wpa_supplicant/wpa_supplicant-0.5.8
make install

If you execute make clean, and then detect error:
-2-

User’s Guide
Makefile: 23: *** Linux kernel source not found.
You can execute this instruction for link the source in to the kernels binary directory.
ln -s /usr/src/linux-headers-‘uname –r’ /lib/modules/‘uname –r’/source
3.2 Install the driver
cd /home/ VT6655_Linux_src_v1.18.05_x86/driver
insmod viawget.ko
If you execute insmod, appear insmod: error inserting ‘viawget.ko’:-1 File exists.
Then, remove the driver: rmmod viawget.ko, execute insmod viawget.ko again.

4.

Driver Configuration/Parameters

The driver can be configured via two interfaces; 1) command and configuration files 2)
network manager and now we use command and configuration files to run the driver.
In next chapter, we will introduce the network manager.
Notice: Don’t use command mode and network manager at the same time.
4.1
OPEN MODE
You can execute iwconfig instruction to obtain the wireless device interface. If you have
some issue, execute man iwconfig for more information.
iwconfig
Then, we can configurate the ESSID and Network address.
iwconfig interface [essid {desired ssid}]
iwconfig eth1 essid WPSE
ifconfig interface [IP address |up|down]
ifconfig eth1 up
ifconfig eth1 192.168.11.127
Verify whether your wireless device is connected or not.
ping 192.168.11.1
Ok, if this information appearing in the screen. You are successful!
root@jel:/home/VT6655_Linux_src_v1.18.05_x86/driver# ping 192.168.11.1
PING 192.168.11.1 (192.168.11.1) 56(84) bytes of data.
64 bytes from 192.168.11.1: icmp_seq=1 ttl=64 time=6.17 ms

4.2
WEP MODE
May be your wireless router can be configured to shared key wep mode. That is the same as
the open-wep mode.

User’s Guide
1. unhidden ssid
We can configurate unhidden ssid or hidden ssid via your wireless router.
ifconfig eth1 down
ifconfig eth1 up
ifconfig eth1 192.168.11.127
iwconfig eth1 key restricted [1] 1234567890
ping 192.168.11.1
2. hidden ssid
ifconfig eth1 down
ifconfig eth1 up
ifconfig eth1 192.168.11.127
iwconfig eth1 key restricted [1] 1234567890
ping 192.168.11.1
If you have any issue with iwconfig , please refer to man iwconfig command.

WPA-PSK TKIP/AES
1. unhidden ssid
You must still be in this directory:
VT6656_Linux_src_v1.18.05_x86/wpa_supplicant/wpa_supplicant-0.5.8/
gedit wpa_supplicant.conf

configurate wpa_supplicant.conf file.

2. hidden ssid
Make sure you still be in wpa_supplicant-0.5.8 subdirectory remain.

Configurate wpa_supplicant.conf file. There are two configurations for hidden ssid.
1) ap_scan=1 & scan_ssid=1 notice the red typeface

When you complete the configuration, save and close it.

Notice: the red typeface, unhidden or hidden ssid depend on if we add this instruction
scan_ssid=1 to the script file.
Then, execute these commands.
ifconfig eth1 up
