Network Manager wireless functionality is broken with marvell 8686 v9 driver

[RajiB]

Create new image with menlow-lpia fsets
install menlow developer architecture
copy marvel 8686 v9 firm ware to /lib/firmware/mrvl
Reboot system
Load 8686_v9.ko ,sd8686.bin,helper_sd.bin modules
Click on Nm-Applet icon, It displays wireless connection as wired.

Note: If another the machine has wired connection , Nm-Applet displays 2 wired connections instead of one wired and one wireless.

I debugged it a little bit. In 'HAL' (hardware abstraction layer) the 'info.category' is set to 802.3 instead of 802.11 for wlan0 device.
When Network-Manager queries 'info.category' property , it gets the values as ethernet. I am guessing it is the driver's job to set this property correctly. So assigning the bug to feng.

[Feng Tang (feng-tang)]

I just upload a fix for this issue to both 2.6.22 and 2.6.24 moblin-kernel, and current HAL info shows the 8686 is a 802.11 device.

please test it

[RajiB (raji-linux)]

Feng,

I verified this bug with 2.6.22-24-menlow-developer kernel and problem is exists. Can you confirm that your changes are merged into moblin repository? I created image with image-creator and tested it on D0 hardware , followed exactly same procedure as before.

[Feng Tang (feng-tang)]

Raji,

You are right. My fix is checking to the 2.6.22-25 version, which is not cutting released yet. So you may need wait for the 2.6.22-25 version which integrates the fix

[Feng Tang (feng-tang)]

Alek has cutting the 2.6.22-25 menlow kernel release, please have a try.

I've run the NM applet and it is recoginzed as a wireless device. Also I used command line to test the WEP/WPA-TKIP, and they worked

hi Feng,
I do some test with 8686_v9 driver on crownbeach.
I test both 2.6.24-5 and 2.6.22-25, the result is the same.
It is reported as a wireles network instead of wired network.
But nm-applet still fail to associate AP.
Even test with AP that without WEP/WPA , nm-applet still doesn't work.

[Feng Tang (feng-tang)]

axel, thanks for the info.

Raji, could you take a look at this issue?

[RajiB (raji-linux)]

Yes, will let you know.

[RajiB (raji-linux)]

I am trying to root cause the issue but blocked right now, because SDIO card does not get recognized on D0 Hardware,with bios ver 72 and kernel 2.6.22-25-menlow-developer kernel , I tested with image created on 3/13.

Earlier when I had same issue with other SDIO cards, it was due to BIOS version, so if this works for you, let me know what version of bios are you using.

[RajiB (raji-linux)]

axel, In between are you able to connect via "iwconfig" command? If you were successful then it is probably NM problem otherwise could be a driver issue.Appreciate it if you could test that while I resolve the SDIO card issue.

Thanks
Raji

[RajiB (raji-linux)]

SDIO card is recognized on one D0 that my peer had, so I am debugging on that machine. When I ran

"sudo iwconfig wlan0 essid Guest" was successful ,but "sudo dhclient wlan0" failed to fetch IP. I am working with feng to resolve this issue.

[Axel Lin (axel-lin)]

I can use iwconfig to assocate with AP.
But NM doesn't work.

I debugged the NM a little bit, and make a small patch for one null string handling issue. With this patch, moblin NM now works basically on Crown-Beach, WEP/WPA-TKIP verified.

[Jing Wang (jing-j-wang)]

feng, if this bug is fixed?

[Feng Tang (feng-tang)]

I've sent Raji a patch for NM, need Raji's confirmation for the bug fix

[RajiB (raji-linux)]

8688 A2 is working well with the NM patch that feng sent but 8686 v9 is broken, for me iwconfig is not able to associate, I think that is causing the NM to not connect , but Network Manager is not crashing with the patch, I am going to check in the fix today 3/20 , please verify on your side also.

[Feng Tang (feng-tang)]

I used latest kernel as well as latest Network-Manager, it works well for both 8688_a2 and 8686_v9. So I change the status to "Fix commited".

For 8686 V9 use, user need make sure the firmware in /lib/firmware/mrvl as exactly the V9 version.

hi...
im using moblin2 beta version on intel atom platform and it is very very slow.
when i checked , i found metacity process taking up nearly 60% of cpu usage making moblin2 beta extremely slow.
please help me in getting rid of this problem..

earlier i was using moblin2 netbook(not beta version)on the same platform which was fast enough but im facing wireless connectivity problem in it.
when i connect the wifi adapter, i find the required network and enter its ssid.
i hav given the network name as guest.
And it shows as if it is connecting(or searching)but it never gives me an ip address or connects to the network.
if i connect a ethernet cable between the router and the moblin system,i get an ip and am able to use the network.
why am i not able to have a complete wireless connection?
please help me in establishing a wireless connectivity.
