Hello everyone, I need help, I bought an adapter with chipset VIA VT6656
usb wifi, but I can not install on my X35 MINI2440 FriendlyARM model,
I'm using kernel zimage_X35, with rotfs_qtopia_qt4.img.

when I plug the device comes this message:

Can anyone help me please ?

jokin 
I have got to install the VIA VT6656 driver on my micro2440 with Linux
2.6.32.2.
There are perfect instructions to make it in this link.

I am a begineer with linux so if I have made it, you will can too.
Good luck.

Hi Jokin,

Kindly let me know where can I download the
VT6656_Linux_src_v1.20.03_x86.rar.

Thanks,
Speed

Please, let us know
Good luck

Hi all,

I succesfully compiled the driver following jokin tutorial.
I got vntwusb.ko driver. I tried to install it on 2.6.32.2 kernel (the
original from FriendlyARM) using insmod vntwusb.ko command, but I don't get
any eth1 interface when using ifconfig.

I'm not an expert of drivers, perhaps I missed something?
Can anyone help?

Thanks!

Hi,

I finally found my mistake: I used ifconfig instead of iwconfig to see eth1
interface.

But I get an error when trying to set the ESSID :

[root@FriendlyARM /]# iwconfig eth1 essid my_essid

Does somebody have an idea?

Hi everybody,

I managed to connect the mini with VIA VNT6656 wifi adapter successfully to
my network with WEP encryption.

In fact, when the driver is installed, nothing is reported by ifconfig.
eth1 is mentionned by iwconfig only. It is necessary to do ifconfig eth1 up
to get VNT6656 interface available for configuration with ifconfig.

So for beginners like me with linux wifi, the correct initialization is:

ifconfig eth0 down
modprobe vntwusb
ifconfig eth1 up
iwconfig eth1 key YOUR_KEY
iwconfig eth1 essid YOUR_NETWORK_NAME
ifconfig eth1 192.168.1.230 netmask 255.255.255.0
route add default gw 192.168.1.1
echo "nameserver YOUR_DNS_IP" > /etc/resolv.conf

then you should be able to connect ping and connect to your network.
Now I have to manage to connect to WPA network with wpa_supplicant.

When i did "make -C kernel_src M=$PWD modules" i got the following:


make: Entering directory `/home/eswara/linux/linux-2.6.32.2'

  WARNING: Symbol version dump

Please can you help me with the above, especially getting 0 modules.

I don`t really get it! It seems to be quiet easy but when I type in the
following:

make -C /opt/FriendlyARM/mini2440/linux-2.6.32.2/ M=`pwd`modules

...I get this error:

make: Entering directory `/opt/FriendlyARM/mini2440/linux-2.6.32.2'

It seems, that it needs a makefile...but there isn`t a folder drivermodules
before....so there isn`t a makefile...

I apologize, if this question is far too dumb...

Thanks in advance!
