D-Link DWL-G120
 

linux is new to me. I really exhausted myself to try to make this adapter work with fedora. I do not have too much hair now :)
Try to use ndiswrapper. Following is what I did
First use unshield to extract the cab file come with the CD.
there is only one inf file and a bunch of sys files. I copy the PRISMA02.sys file of directory Drv9X and PRISMA02.inf to /etc/ndiswrapper/prisma02/ folder.
Then I got lost.
if I use ndiswrapper -i PRISMA02.inf
then ndiswrapper -l
I got bad driver.

I try to use modprobe or iwconfig. The system shows no such command.

I really do not know what to do from here.

I will really appreciate if anyone can help me.

you do not have to copy these files to the /etc/ndiswrapper directory. you can run "ndiswrapper -i file.inf" from your home directory, although it may not make a difference. If it still doesn't work, you're going to have to look around for different .sys and .inf files.

the commands modprobe and iwconfig, like much else under fedora usually have to be prefixed with /sbin

# /sbin/modprobe

# /sbin/iwconfig

Thanks for the help!


I used
ndiswrapper -i PRISMA02.inf
ndiswrapper -l

Got
installing prisma02
installed ndis drivers:
prisma02 driver present

Then:
/sbin/modprobe ndiswrapper

Got
FATAL: Error inserting ndiswrapper (/lib/modules/2.6.11-1.1369_FC4/misc/ndiswraper.ko):Operation not permitted

When I use /sbin/iwconfig

Got
lo no wireless extensions.
sit() no wireless extension


How do I deal with that error? Your help is appreciated.

Check the output of "dmesg" for output relating to ndiswrapper. Also, check your system log (it's in /var/log/)

Then you may want to take a look through this page

http://ndiswrapper.sourceforge.net/p...dex.php/Fedora

and also google your error.

Make sure you're using the newest stable version of ndiswrapper (v. 1.2 as of now)

Cheers

[Edit]

Also, if you got an warning message during "make" relating to the kernel being compiled with 4K stack size, you should check out this thread

Almost got it
 

Thanks for the help and encouragement. After reading those articles and tried several times, finally, I got to the point:

iwlist wlan0 scan

I can see all the accessible wireless points. Feel close to success :)
Then use /sbin/iwconfig wlan0 essid Earth (Earth is my ESSID)
then use /sbin/iwconfig to show the configureation. Everything is cool.


Since I am using WEP.
I try to use /sbin/iwconfig wlan0 key restricted ********** (********** is the 10 digit key)
got error info: Error for wirless request "Set Encode" (8B2A): SET failed on device wlan0; Operation not permitted.

I think after this point, I should be able to link to the networks.

Thanks for your surpport!!

Unknow host
 

after delete the loaded driver and reload the driver that problem is gone.

So, now I use /sbin/modprobe ndiwrapper to load the module. It goes well
/sbin/iwconfig show the status
/sbin/iwlist scan lists all the available access points.
/sbin/iwconfig wlan0 essid ESSID assign the essid to wlan0
/sbin/iwconfig wlan0 key restricted 8888866666 goes well this time.
/sbin/ifconfig wlan0 up activate the network interface

everthing goes without errors.

After this point, it seems it should work.

I use ping

ping www.cnn.com Then the error info unknow host www.cnn.com
ping 64.236.16.84 Then the error info Network is unreachable.


What do I need to do to get over with this last obstacle?

Thanks!

Try hooking the interface up with dhcp

# /sbin/dhclient wlan0

Then check the output of ifconfig - you should now have an IP address

after /sbin/dhclient wlan0 without error information
then use /sbin/ifconfig

lo
inet addr:127.0.0.1 Mask: 255.0.0.0
...

wlan0
inet6 addr: fe80::211:95ff:fe4a:dc80/64 scope:link
...

that does not look like ip address

Ping still does not work.

what should I do next?

Check the output of /sbin/iwconfig

You should see your essid that you assigned in iwconfig. If it says off/any, or if the AP shows just a row of zero's then iwconfig did not pick up the information correctly. Make sure the mode is set correctly (usually this is "managed"). Try setting the wep key to "open" rather than "restricted". Post the output of iwlist scan and iwconfig if you're still having problems.

Cheers

still not working
 

Thanks for your patience! Please stay with me. I am almost done :)

ping still not working

following are the output from /sbin/ifconfig /sbin/iwconfig /sbin/iwlist

One last step DNS
 

Now. Actually, if I ping some ip address, it is working.
I can even use mozilla if I input ip address.
But once I use something like www.cnn.com, I got unknow host error. I guess it must be related to DNS setting. But I do not know how. One more step I am ready to go :)

Thanks butler
