ipw3945 wireless drivers

rmh3093 · Posted: Fri Feb 17, 2006 5:40 pm Post subject: ipw3945 wireless drivers

Since there is no thread about this I figured I would start one. Anyone that buys a notebook with the new Intel Centrino Core Duo will have an IPW3945 wireless card. Intel's site says drivers will be available Q1 2006. The sourceforge project the ipw3945 drivers was just registered at the beginning of the month. Here is a link to the sourceforge project for those that are interested:

i'm waiting also
if anyone needs more information or beta-tester - post it :lol:

i have some more problems on my inspiron, but most import is the wireless-connection.

(: 0c:00.0 Network controller: Intel Corporation Unknown device 4222 (rev 02)

i have tried the way to patch the kernel to be able to work with 16k stacks and got the card activated while using ndiswrapper with the w39n51.inf from intel, but that was not totalay working - it only seems to be ;-)

but the ap never get locked withe the card .. and it was very unstable and sometimes the maschine completly freezes - so i have paused testing that way :-(

here is lspci output, mabe needful :?:

Eagerly waiting for the drivers too... I have a Dell Inspiron 9400 with an nVidia 7800 Go. Fortunately only WiFi and the SD card reader do not work.

Hey,

I have got the same problem with my wireless card on my Dell Inspiron 9400, which I got two weeks ago. I also tried to patch the kernel, but trying to insert the module gave me an error, that the ndiswrapper.ko is of invalid format. It was independent on whether or not the SMP was on.

I haven't yet tried to make SD card reader to work. Moreover i have troubles with screen resolution and audio control. Unfortunately I have bought a crapy graphic card - Intel Media Accelerator 900 Graphics. I cannot force it to work properly with xorg using VESA. It stretches the display as its natural resolution is 1440x900 which is unreachable for me...

Anyway, did somebody of you managed to get xorg with 1440x900 working, please post your xorg.conf?
The problem with sound I have seems to be general for all users of Intel HDA... When I plug in the headphones the sound is still coming also through the internal speakers of the laptop. This is really bad, if I want to listen to music while working at the office without annoying my colleges...

Has somebody solved this problem???

unfortunatly or not i have another grphic-card in my 9400, i choosed the 7800 go, which work fine with the nvidia-driver
for my audio i have choosen the way over alsa-driver ( type into /etc/make.conf "ALSA_CARDS="hda-intel" - emerge alsa-driver and execute alsaconf)
i got sound, but not from the subwoofer.

Please bear with the original poster. This thread should talk about Wireless NIC 3945 drivers and issues. For more general questions and support on the Dell Inspiron 9400, use the dedicated i9k4 thread instead.

Hi people.

I've just created and tested my own ebuilds for ipw3945.

Preliminary notes

Intel Licences

The driver is a set of three packages from Intel: the driver module, the microcode and a regulatory daemon. Only the driver module is GPL'd. The other two are Intel-specific licenses. Hence the presence of two Intel licenses in the tarball. These licenses are provided with Intel's packages, which we can find at sourceforge.

My ebuilds do reference these licenses. Hence they must exist in /usr/portage/licenses before the ebuilds are used. They're included in the tarball and will therefore be extracted to the required directory.

Unofficial ebuilds

Since these are not official ebuilds they will be placed in a portage overlay directory. In my example I'll assume the portage overlay resides in /usr/local/portage/. See Gentoo Wiki on how to create and use third-party ebuilds with portage overlays.

Install Instructions

Download and extract the tarball from the above link:

i have not tried your e-build but I do have ipw3945 working with 2.6.16-rc4-mm2, thanks for beating me to ebuild, i will try it out!

I'm not sure why, but I had to create an init script to manually delete the /var/run/ipw3945d.pid file at shutdown or else it would not start up automatically with the automatic modprobe at boot.

Thanks for your work!

Thanks for all your help VinzC, I'm slowly getting there with my 6400.

Has anyone got wpa working with this card?

I'm getting

As per Intel requirements, use the latest version of wireless-tools - you might have to unmask it. You might have to use an unmasked version of wpa supplicant as well.

Solved it, I was trying -Dext instead of -Dwext.

-Dwext works like a charm. Thank you.

P.S. There is a new version of the driver out :-)

Hi!
I can't connect by IPW3945ABG to wifi AP.

lspci

03:00.0 Network controller: Intel Corporation Unknown device 4222 (rev 02)

I use my old working wpa_supplicant.conf
But
wpa_supplicant -w -i eth2 -c /etc/wpa_supplicant.conf -Dwext
say only
ioctl[SIOCGIWSCAN]: Resource temporarily unavailable
what's the problem?

VinzC: I still haven't been able to try your ebuild since I cant emerge ieee80211 but I was poking around and notice that the default Makefile comments out support for monitor mode and qos support. It an easy tweak for people using the ebuild, maybe you wanted to include it as a use flag option or something.

Anyway, I hate using ebuilds for kernel drivers so I made a patch for the 2.6 kernel series which adds IPW3945 support. There are config options to add support for QoS and promiscuous mode.

VinzC: when installing ieee80211, after i remove the old headers and then the ebuild extracts the source ,appllies the patches then just before it builds the ieee80211 modules the build fails and it complains about missing files. When i try to do the install manually (i extract the ieee80211 bz2 file to a tmp dir and run the install) after i type 'make' all the files in the working dir dissapear, i dont know where they go but that is what is keeping from using he ieee80211 outside of the kernel tree

One out of three times the /sbin/ipw3945d --quiet fails to start, the module however loads fine.

I increased the sleep to 1.0, but that hasn't fixed it.

Is it just me?

for those having problems getting the ipw3945d started at boot using /etc/modules.d/ipw3945 I made an rc script to start and stop the daemon
