IPv6 multicast receiving and orinoco

Hi,

IPv6 multicast receiving (destination MAC address 33:33:00:00:00:01) is not
possible out-of-the box with Orinoco Silver cards.  I tried with almost every
firmware version and with the latest CVS driver as well as the one in vanilla
kernels.  Nevertheless, multicast receiving becomes possible if the interface
is put into promiscuous mode and even after the promiscuous mode is unset
(read: it works if I launch tcpdump on the interface and kill it immediately).

I've seen that in the past someone already had come across this problem, but
this was one and a half year ago and I found it worth asking again in case
anyone had more information since then.

Does it happen on all orinoco cards or only the "Silver" series?  Is there
possibly some version of the driver not exhibiting this strange behavior?

I use a bunch of those cards on iPAQs, laptops and desktop computers in a
testbed for routing protocols for ad hoc networks, so I need to know whether
implementing the dirty "promisc-in-and-out" hack is the only way to go.

Which firmware version?

I think there may have been some versions which enable promiscuous
mode when any multicast addresses are listed.  It certainly does this
on all Intersil firmware cards, which don't appear to have a multicast
list in firmware.

says:

guffy:/home/bencer# ifdown eth1
Error for wireless request "Set Mode" (8B06) :
    SET failed on device eth1 ; Invalid argument.

eth1: Looks like a Lucent/Agere firmware version 8.70

what's the problem ?

thanks,

Question about USB adapter from Orinoco-USB

Hello,

  I have got one question about usb-pcmcia adpater from orinoco usb.
  When I remove orinoco classic gold pcmcia from this adapter and I
  will insert prism-based pcmcia card how can I got it work?

  This question is now theoretical - I didn't try, because I haven't
  got any prism-based pcmcia card 

  But in orinoco-head there is prism-usb driver. Is it for prism cards
  in orinoco pcmcia-usb adapter? I think so, because first orinoco
  card were not on hermes-I, but on Intersil Prism II... But I expect
  confirmation from orinoco developers...

  Question to Chris Rankin and normal users: did you try to insert in
  orinoco pcmcia-usb bridge other cards? I view orinoco-usb module and
  there is sign, that it use some from early linux-wlan-ng code, so I
  think, that this combination should work with current
  linux-wlan-ng...

  Can somebody confirm this or refuse? Thanks

Now I can see, that this combination *should* theoreticaly work with
orinoco-usb, not prism-usb driver from orinoco-cvs HEAD branch  I
view source of prism-usb and there is no ezusb support. But
orinoco-usb will still support this card with prism card inside,
because orinoco-usb support pcmcia-usb bridge and it use orinoco.c.

In orinoco.c I can find:

* A driver for Hermes or Prism 2 chipset based PCMCIA wireless
 * adaptors, with Lucent/Agere, Intersil or Symbol firmware.

 So, orinoco-usb should still support card after changing pcmcia from
 hermes-I to Prism - is it right?

problems with orinoco_usb

Hello all,

i have some problems with orinoco usb on an debian system with the
2.6.11-1-686 Kernel. The orinoco card has already worked for some weeks and
now somehow the driver was damaged (i dont know why). modprobe produces the
following error:

modprobe orinoco_usb
FATAL: Error inserting orinoco_usb
(/lib/modules/2.6.11-1-686/kernel/drivers/net/wireless/orinoco_usb.ko):
Unknown symbol in module, or unknown parameter (see dmesg)

and dmesg gives 
orinoco_usb: Unknown symbol release_firmware
orinoco_usb: Unknown symbol request_firmware
orinoco_usb: Unknown symbol register_firmware

So i tried to repeat the things i did some weeks ago to make the card
working again, but today unfortunetly without success.

I took
ftp://ftp.avaya.com/incoming/Up1cku9/tsoweb/avayawireless/AV_WINXP_PC_USB_SR0201.zip
and 
http://folk.uio.no/oeysteio/orinoco-usb/get_ezusb_fw

Copied these two files into the same folder and execute 
sh get_ezusb_fw

This produces the file orinoco_ezusb_fw exectly as its described here
http://folk.uio.no/oeysteio/orinoco-usb/install.html

It seems to me that you are compiling against the kernel that has
firmware download support (CONFIG_FW_LOADER defined in .config), but the
kernel you are running doesn't have that option.

Make sure the kernel sources match the running kernel.

Another possibility is that firmware download support was compiled as a
module and you lost that module or it fails to load.

Re: problems with orinoco_usb

Thanks for helping. 

I got it to work now with the 2.6.12-rc4 Kernel!

Subject: Cannot install orinoco-usb under Ubuntu

Hello,

  Some time ago I wrote how to install orinoco-usb under Debian
  Sarge/Sid. Unfortunately this procedure cannot get working under
  Ubuntu Hoary 5.04. I don't know why...

  I copied firmware to proper hotplug directories, but after plug in
  USB cable there is always "No firmware to download...". I tried to
  hardcode firmware to driver - I copied firmware files to orinoco-usb
  compilation directory, edited orinoco.c (defined hardcode), but
  hardcoding is totaly usunasble - after it still I get errors "no
  firmware to download".

  Did somebody try to install orinoco-usb under Ubuntu? For me this
  distro is not working with orinoco-usb driver. I even compiled
  kernel myself from 2.6.12 kernel.org sources - there is no
  difference...
