D-Link DWL-G122 Rev. C1

[mbinz]

Hello,

Searching forum I found many posts saying the DWL-G122 works with BT out of the box, and a few ones saying BT wouldn't even recognize it.

It seems to be the DWL-G122 with the revision C1 that makes the problems. "Lucky" as I am, mine has revision C1 too and of course it doesn't work, iwconfig doesn't even show it.

Searching the web, I found out that rev. C1 uses a different chipset (RT2571W)....
There are linux drivers for it available here: http://www.ralinktech.com/supp-1.htm, but my knowledge about linux is very limited so I didn't yet try to install them.

Has anyone managed to use a DWL-G122 Rev. C1 with BT?
Will it be supported by BT in the future? To install special drivers is a bit pointless with a live cd, cause I'd have to do it everytime I run it, right?

Cheers
Marco

Hi. I'm also a "lucky" owner of this USB card.
I'm in the way to start some tests with this HW. Unfortunately my work doesn't allow me a lot of spare time to do it as quick as I'd like. Anyway I had enough time to think about three different options:
1) I'll check with ndiswrapper and windows drivers
2) I'll try to compile drivers from http://www.ralinktech.com/supp-1.htm
3) And finally, if not lucky, because of the kernel version I'll wait to next release of backtrack and try drivers from http://rt2x00.serialmonkey.com/
If successful, I'll let the community know my progress. Meanwhile if you want to contact me for something, just send to me a private message.

Hi,

Maybe I'll have some time on the weekend to experiment a little myself.

I think we should only aim for the ndiswrapper solution if everything else fails. I don't know if monitoring mode is available with ndiswrapper and I'm quite certain injecting isnt. Can anyone confirm this?

What's the difference between the offical ralink drivers and the rt2x00 project? Do the offical drivers lack some features? I mean there must be a reason for the rt2x00 project if the manufacturer itself already provides an opensource driver.

Cheers

Solutions:
1) Works, but can't set monitor mode and use aireplay
2) Drivers require an up-to-date kernel
3) Sure!

monitor mode will NEVER be available with ndiswrapper since you're using windows drivers (only ad-hoc and managed mode)

I just got the rt2x00 drivers. They compiled fine, and modprobe rt2700 showed now error, but still iwconfig only lists lo, eth0, and sit0....

[mbinz]

I got the drivers from ralink (RT73_Linux_STA_Drv1.0.3.0.tar.gz) and added the product ID and vendor ID found by lsusb (07d1:3c03) to the file rtmp_def.h to get the driver to recognize the DWL-G122, as mentioned in this thread: http://61.222.76.235/phpbb2/viewtopic.php?t=2134

After that, iwconfig finally listed the device rausb0 but the ralink driver doesn't seem to support monitoring mode, iwconfig rausb0 mode monitor results in Error for wireless request "Set Mode" (8B06) :
SET failed on device rausb0 ; Invalid argument.


So I tried the same thing with the rt2x00 drivers (rt2570-1.1.0-b1.tar.gz), there the file to add the IDs is rt2570sw.h. With the freshly compiled rt2x00 driver iwconfig lists rausb0 too, but when I tried to do ifconfig rausb0 up my computer completely froze up (ifconfig used 99% processor time) and I had to reboot.

You give up too easily. What card did you buy instead, do you know of one that works out of the box? (Actually I thought the DWL-G122 would....)

Update on my testing:

I've tried both ndiswrapper and RT73 drivers from Ralink. They have worked. Ndiswrapper appears to be easier. On the other way the RT73 driver is tricky to get working but it appears to be stronger.

Anyway, none of them allows me to configure in monitor mode, so basically I only can connect to TheNet and surf over there, without using the excellent tools that BackTrack is offering.

I also have tried rt2570 driver from http://rt2x00.serialmonkey.com/ , but same effect as observed by mbinz: ifconfig (almost) hangs the system, and of course no network.

So my choice is: I'll try to use new rt2x00 driver from http://rt2x00.serialmonkey.com/. Unfortunately, they need an upper version of kernel than currently existing in BackTrack, so I'll need to wait.

So when new version of BackTrack comes, I'll give a try. I hope to get some patience

Cheers.
