My notebook is MSI MegaBook s420, support 802.11g MiniPCI Wireless Network Adapter a product from RaLink Technology.

Based on this page
http://baruch.ev-en.org/laptop-s420.html
I used the rt61pci or rt61 driver.

I've got the rt61 driver from
http://www.ralink.com.tw/support.php?s=2
Select 'RT2501PCI/mPCI/CB(RT61:RT2561/RT2561S/RT2661)'.

And i had tried to install the driver packages 2009_0123_RT61_Linux_STA_v1.1.2.3 based on it's README file. This is README file installation.

Build Instructions:
====================

1> $tar -xvzf RT61_Linux_STA_Drv_x.x.x.x.tar.gz
go to "./RT61_Linux_STA_Drv_x.x.x.x/Module" directory.

2> $cp Makefile.4 ./Makefile # [kernel 2.4]
or
$cp Makefile.6 ./Makefile # [kernel 2.6]
or
$cp Makefile.RTL865x ./Makefile # big endian platform

3> [kernel 2.4]
$chmod 755 Configure
$make config # config build linux os version

4> $make all # compile driver source code
4.1> $make install

5> $cp rt2561.bin /etc/Wireless/RT61STA/ # copy firmware
$cp rt2561s.bin /etc/Wireless/RT61STA/
$cp rt2661.bin /etc/Wireless/RT61STA/

6> $dos2unix rt61sta.dat
$cp rt61sta.dat /etc/Wireless/RT61STA/rt61sta.dat
# !!!check if it is a binary file before loading !!!

7> $load
#[kernel 2.4]
# $/sbin/insmod rt61.o
# $/sbin/ifconfig ra0 inet YOUR_IP up

#[kernel 2.6]
# $/sbin/insmod rt61.ko
# $/sbin/ifconfig ra0 inet YOUR_IP up

========================================================================

But Error occurred, when i load the last command :

$/sbin/insmod rt61.ko
$/sbin/ifconfig ra0 inet YOUR_IP up

the error are like this:

SIOCSIFADDR: No such device
ra0: ERROR while getting interface flags: No such device
ra0: ERROR while getting interface flags: No such device

is there any suggestion and solution to this problem? Thank you for your kind attention.

I think you've been misled by the README. Try wlan0 instead of ra0.
I've used the RaLink rt61 driver, and more recently the rt61pci module included in kernel 2.6.31, and they've always come up as wlan0.

i had tried your suggestion to replace ra0 with wlan0. but i still get the same error.

SIOCSIFADDR: No such device
ra0: ERROR while getting interface flags: No such device
ra0: ERROR while getting interface flags: No such device

or maybe my network setting in Debian is not active?
if so, how can i activate the network setting?

thank you.

First you need to run 'lsmod' to see whether the module has actually been loaded. Also take a look at the system logs for clues.

Then run 'iwconfig' to see what interfaces it sees. I know squat about Debian, so I can't offer more specific help.

i use Ndiswrapper and problem solved.
