[gentoo-user] Kernel 2.6.27 and iwl3945-ucode

[gentoo-user] Kernel 2.6.27 and iwl3945-ucode

[Marco]

Hi all,

I am trying to get my wireless adapter (Intel 3945ABG) running.
following the instructions on http://en.gentoo-wiki.com/wiki/Iwlwifi I
compiled the kernel accordingly. Now the howto states:

 For kernel 2.6.27 and later, use the second slot(version 228.57.2.21)
which needs to be unmasked in package.keywords.

Since I am rather new to gentoo, I am not really sure what to do. I added

=net-wireless/iwl3945-ucode-228.57.2.21 ~amd64

to /etc/portage/package.keywords to use the version mentioned. Testing
what would be installed:

emerge net-wireless/iwl3945-ucode --pretend --verbose

These are the packages that would be merged, in order:

Calculating dependencies... done!
[ebuild  N    ] net-wireless/iwl3945-ucode-15.28.1.6  66 kB

Total: 1 package (1 new), Size of downloads: 66 kB

So version 15.28.1.6 would be used... What am I missing?

Thanks for your help!

You somehow mixed iwl4965 and iwl3945. Version 228.57.2.21 belongs to
iwl4965.

If you really want iwl3945, you don't need to unmask/keyword anything.
I'm on 2.6.28 with version 15.28.1.6.

For iwl4965, I don't see any versions which are not marked stable (I'm
on AMD64).

I see. It was not really clear to me if it is only related to 4965 or
if it also is true for the 3945. Thanks for pointing out!

One more question: I followed the howto for Intel 3945 and also the
handbook ( http://www.gentoo.org/doc/en/handbook/handbook-x86.xml?part=4&chap=4
). I am using wpa_supplicant. But I think I am missing now a
configuration for /etc/init.d/net. What information do I have to
provide there?

modules_wlan0=( "wpa_supplicant" )
where wlan0 is your wlan interface.

If you want different settings for different nets, you can do things
like this:

config_ESSID1=( "192.168.2.2 netmask 255.255.255.0" )
routes_ESSID1=( "default via 192.168.2.1" )
dns_servers_ESSID1=( "192.168.4.1" )
config_ESSID2=( "dhcp" )

Otherwise, dhcp is assumed.

 You can try Wicd which is  a great network manager, until you are more
familiar with gentoo/wifi configuration.
 I have the same chip, with wpa2, wicd handless this without problems.

This is cool! For the moment this is perfectly ok for me!

Thanks for the tips!
