[gentoo-user] ipw3945 and 128 bit WEP encryption

[gentoo-user] ipw3945 and 128 bit WEP encryption

[Peter Kelly]

Holas!

I recently bought a Dell Inspiron e1505 laptop.  I purposely got an Intel 3945 
wireless card installed, because I read that it was more linux friendly than 
the dell wireless card.

I emerge'd  ipw3945, but can't get it to work.  I get an error 

error for wireless request "Set Encode" (8B2A) 
Operation not supported

when I run 
# iwconfig eth1 key "26 hex character key"

when trying to set the the encryption key for my home network.  I'm certainly 
not going to turn off WEP encryption, so I need to fix this.
I've got a crappy 6 year old computer using a pcmcia and the airo module that 
has no issues at all.  I used the same /etc/conf.d/wireless file, so that 
essid, key, etc, were all from a working setup.

I'm sure that I'm doing something so simply wrong, that the 4 hour delay to 
figure out that /dev/sda6 requires scsi sata drivers built into the kernel, 
will make this seem stupid.

It's currently off building KDE/X on the only available wired jack in the 
house (who thought I'd ever need 13 switch connections?), so if I mis-typed 
something, I apologize.  Please ask.

Thanks.

Peter

is ipw3945d running?

Also, make sure that you have pressed the WiFi button to switch on the 
hardware on that laptop, or have switched it on in the BIOS (not familiar 
with the model).

Yes, the daemon is running.  It starts when you modprobe ipw3945.
There isn't a wifi switch that I've found.  There is an LED that blinks 
slowly.  The card appears to be on.  I just can't get it configured.

Thanks.

Well I can attest that the wep will work with this card...I have it working.

What versions of net-wireless/ipw3945, net-wireless/ipw3945-ucode,
net-wireless/ipw3945d, and net-wireless/ieee80211 do you have
installed?  In other words, what is the output of:

emerge -pv net-wireless/ipw3945 net-wireless/ipw3945-ucode \
    net-wireless/ipw3945d net-wireless/ieee80211

And I suppose the outputs of "iwconfig -v" and "iwconfig" could help too.

Thanks, Richard.  I'm not sure how I did it, but suddenly it 'just worked'.  

What I can't do is 
/etc/init.d/net.eth1 restart

If I shut it down, then I need to either reboot or kill the ipw3945d, then 
start it again.  I put the ipw3956d call in /etc/conf.d/local.start, which 
brings it up fine.  Very kludged, but maybe once I get X running at more than 
1024x768 I'll spend more time on it.  Getting the wireless part working so I 
could emerge away from a switch was the first biggie.

Rather than starting ipw3945d in local.start, it is probably better to
start/stop it with the module.  You should have a
/etc/modules.d/ipw3945 file that contains:

----
install ipw3945 /sbin/modprobe --ignore-install ipw3945 ; sleep 0.2;
/sbin/ipw3945d --quiet
remove ipw3945 /sbin/ipw3945d --kill ; sleep 0.2; /sbin/modprobe -r
--ignore-remove ipw3945

alias pci:v00008086d00004222sv*sd*bc*sc*i* off
alias pci:v00008086d00004227sv*sd*bc*sc*i* off
----

If so, run "modules-update" to regenerate /etc/modules.conf and
activate the instructions.

Note: I'm not sure which of the above lines I modified myself and
which ones came from the ipw3945 package.  But the first line starts
the daemon when the module is loaded, the second stops it when the
module is unloaded, but only if you use "modprobe -r ipw3945".  It
will _not_ work correctly if you do "rmmod ipw3945".

The third and fourth lines prevent the module from being loaded
automatically by udev, and are necessary because /var on my system
isn't mounted when udev starts.

HTH,

Are you sure about that?  It doesn't do that for me.  Try a 'ps ax | 
grep ipw'.  In addition to the kernel daemons [ipw3945/0] and 
[ipw3945/1], there should be an instance of the userspace daemon 
/sbin/ipw3945d, which for me is not started except through 
/etc/init.d/ipw3945d.

Maybe you need to modprobe ieee80211_crypt_wep and the relevant crypto 
algorithm modules? That's what I remember being the issue when the card 
generally works but WEP doesn't. I think the older wifi supporting code 
doesn't let you separate this stuff out, while the new code doesn't 
automatically handle loading modules when necessary. I remember dmesg 
being more informative than iwconfig when it fails, also.
