[gentoo-user] Wireless Issue

Hi,

I have an Intel 3945 wireless adaptor in my laptop.  I have always used
the ipw3945 driver in gentoo because I have never had any luck with the
iwl3945 driver.

I currently am running the 2.6.30-r10 linux kernel and previous to that
I ran 2.6.30-r6.  For the last 2 kernel builds that I have done, I have
been unable to build the ipw3945 driver because it is looking for TKIP
(and a couple of other security things, but I don't recall off the top
of my head).  The point is, I used to be able to select TKIP and the
other things in the kernel, but cannot find those things specifically in
the 2.6.30 range of kernels.

Tonight I, again, following the wiki, tried building the iwl3945 driver
into the kernel, but had no success.  I need to get wireless working
because I am changing isp's and will not longer be using an ethernet
connection, but a dsl one.

I don't know if it matters, but I am using wireless-extensions as
opposed to wpa-supplicant because it doesn't seem that wpa-supplicant
supports the Intel 3945 wireless adaptor.

Any help would be appreciated.

Regards,

Colleen

Have you found out yet what really isn’t working? It could be a number of 
things, but when dealing with kernel drivers “it doesn’t work“ is not enough. 
;-)

IWL3945 and wpa_supplicant are working just fine over here. My only difference 
is that I’ve built it as a module. Here’s what I set in the kernel config.

Networking
  [*] Wireless
    -*- Wireless extensions
    {M} Common routines for IEEE802.11 drivers
    <M> Generic IEEE 802.11 Networking Stack (mac80211)
Device drivers
  [*] Network device support
    Wireless LAN
      [*] Wireless LAN (IEEE 802.11)
        <M> Intel Wireless WiFi
          <M> Intel PRO/Wireless 3945ABG/BG Network Connection (iwl3945)

# lsmod | grep iwl3945:
iwl3945                80412  0 
iwlcore                98076  1 iwl3945
mac80211              142636  2 iwl3945,iwlcore
cfg80211               82108  3 iwl3945,iwlcore,mac80211

IIRC, there’s nothing more to it, really.
I also added suppor for tun/tap and devices and some ppp options because I use 
vpn on my Uni’s network, but I don’t reckon they’re a requisite for wireless. 

Then I grabbed iwl3945-ucode from portage, and that was it, IIRC. Just last 
weekend I rebuilt my system from scratch and it worked right away after I 
installed the ucode, dhcpcd and wpa_supplicant. Then I created the symlink 
net.wlan0 -> net.lo in /etc/init.d and added it to the default runleven via 
rc-update. Oh yeah, I had to add the driver module iwl3945 to 
modules.autoload.d/kernel-2.6, because it didn’t get loaded (by udev?) at 
boot. Not sure if that is still necessary, but it was at some point in the 
past, obviosly.

Lastly, you need of course a correct wpa config, which is no rocket science 
either. Here’s mine for our WPA2 home network:

network={
	ssid="our ssid"
	key_mgmt=WPA-PSK
#	group=TKIP
	psk="our secret keyphrase"
}

To connect, I did:

# wpa_supplicant -c/etc/wpa_supplicant/wpa_supplicant.conf -Dwext -iwlan0 &
# dhcpcd wlan0 &

and I was ready to go (That is from my memory, it may contain typos or similar 
errors).

It should be build as a module because the driver needs access to
external firmware, and unless you are using an initrd with the external
firmware built into it, you're best of with a module.

FWIW, I've also been using the iwl3945 for as long as I can remember and
haven't had any issues.

[gentoo-user] Wireless Issue

[CJoeB]

Hi,

I had wireless working just fine back when I was using the
2.6.27-gentoo-r8 kernel.  Since upgrading to the 2.6.30 series of
kernels, I haven't been able to get it working.  I was using the ipw3945
driver, but this driver needs TKIP and something else (don't remember
what) set in the cryptographic section of the kernel source.  I can't
seem to find where that is located, if it is in the kernel that I am
currently running - 2.6.31-gentoo-r10.

I've tried using the corresponding driver within the kernel, but I still
get told that my wireless connection does not exist and that I should
verify the hardware or kernel module driver.

I have also always used wireless-tools.  I know wpa_supplicant is
supposed to be better because you can enable WEP encryption, but I tried
to set that up too and I still get told that my wireless connection does
not exist and that I should verify the hardware or kernel module driver.

I'd be happy just using wireless-tools if I could get the ipw3945 driver
to build, but can't without TKIP.  Does anyone know if this setting has
been taken out of the kernel source or if it is just located in some
obsure place that I can't find?

Regards,

Colleen

I'm sorry if I'm mistaken, or if this comes across as awfully rude but didn't you ask the same question back in March? Did you have a look at the replies from then to see if that could help with this issue?
Also you can search within the kernel by entering '/' a search field will come up, and if you know part of the name (past thread of same title should reveal that), you should be able to locate it.

Hope it helps

If I remember correctly, I think there were major changes to kernel
wireless infrastructure introduced in 2.6.30. And in wpa_supplicant
some changes had to be made for some people, like changing the driver
(in my case from -Dmadwifi to -Dwext). Sorry I'm not familiar with
your particular driver but I know there were major changes in general
around that time.

You may also need to emerge net-wireless/iw if you don't have it already.

In the crypto/cipher section of the kernel I've found it easiest to
just build all of them as modules and then they're available if
needed.

After you built your new kernel, did you re-emerge iwl3945-ucode?  I
usually forgot that step when upgrading my kernel (along with
nvidia-drivers).  I believe if you look in /var/log/messages, you'll see
a message about missing microcode if this is the case.

Also, I use wireless-tools just fine with mine, and it's running
2.6.31-r10 (I keep meaning to upgrade my kernel to the latest stable).
