p54usb not working on DWL-G120 Spinnaker wireless card

p54usb not working on DWL-G120 Spinnaker wireless card

[d i]

Hi,
I can't get my wireless card DWL-G120 Spinnaker to work with the p54usb module which is in the kernel tree. 
The kernel help page for the p54usb module says that this module should work with the DWL-G120 Spinnaker wireless card.

I now have kernel 2.6.25-r7, but I kept trying to use the p54usb module with my card unsuccessfully since it appeared in the kernel tree (around February this year) -- it never worked. 
I use firmware version 2.5.6.0 from the prism54.org website. I tried with other versions of firmware as well, but most of them did not even load up (error -22 and error -110).

With firmware 2.5.6.0 the module loads up, but scanning for APs reveals no answer, ever. If I set an ESSID of a network I KNOW is around and not crypted it does not set the AP address and the "Link Quality" is always 0  and  it never connects.
The card can not be set in monitor mode.
I can set the card in ad-hoc mode ONLY if the interface is down. If afterwards I try to bring the interface up (with ifconfig), I get an error, and the interface does not come up.
After a while (never fixed) the kernel Oops. 

Both the failure to work and the final unpredictable kernel Oops are always reproducible, although the time it takes the kernel to Oops varies every time.

I've tried this with 3 desktop computers and 1 laptop and all have the same behavior. The wireless card works well in windows or in linux under ndiswrapper.

Did anyone manage to have this wireless card (DWL-G120) working with this module (p54usb) ?

Thanks,
Daniel.

Have you emailed the developer of the driver?

Also, the linux-wireless mailing list would probably be the better place
to ask this kind of question.

Hi,

Yes, I did contact the developer several times. Last time (in May) he told me he is not involved in the project anymore. However, he didn't told me who is, or who I could ask about it, nor any comments on how I (user-level) could solve this problem.

Thanks for the hint. I've posted the question there. If anyone is interested/curious to follow this problem on, here is the link to it: http://comments.gmane.org/gmane.linux.kernel.wireless.general/19429

 

Thanks,
Daniel.

hmm, there are about 5 different types of firmwares... 
- TWO for minipci cards 
	- fullmac are exclusively for prism54
	- softmac are only for p54
- one for isl3886 chips with a net2280 pci-usb-bridge (your card/stick)
- one for isl3887 chips (they have a native USB-Interface)
- one for conextant's cx3110x (spi interface) (found on some Nokia N800/N770 I think
	Johannes did some work here, but that was long ago)

so stick with prism54.org recommendation 2.5.6.0 ...

(Ad-hoc isn't supported... there was a patch but no review!)

And you always have to bring the interface down to change the mode
it's more a mac80211 thing than p54's fault...

Ad-hoc isn't supported and monitor-mode will filter out anything
except beacons...

Hmm, I found 2 problems and I guess there are some more...
(Will post them later today or tomorrow, my timezone is CEST)

but you'll need:
- wireless-dev git-tree (which can be found here:
http://git.kernel.org/?p=linux/kernel/git/linville/wireless-testing.git )
- the "patch" - utility
- time to test & report...

hmm, do you have usbmon enabled in your kernel? Or is there any other facility
to "monitor" what ndiswrapper or p54 is doing? because this logs are very handy!

hmm, I haven't heard of anyone with success...
