Hi Fitzcarraldo,
thank you very much for the explanations.

Hmm, I wonder if that switched off USE flag (savedconfig) is the problem. What are the contents of your directory /lib/firmware/?

Well, that looks OK to me: you do have the microcode file iwlwifi-5000-5.ucode (plus iwlwifi-5000-2.ucode and iwlwifi-5000-1.ucode) in /lib/firmware/

Regarding your first post:

Code: Select all

sabayon harmon # lsmod | grep iwl
iwlagn                180153  0
mac80211              165909  1 iwlagn
cfg80211              119001  2 iwlagn,mac80211

On PCLinuxOS WiFi works fine:

Code: Select all

[root@localhost ~]# lsmod | grep iwl
iwlagn                170878  0
iwlcore                52621  1 iwlagn
mac80211              189461  2 iwlagn,iwlcore
cfg80211              126787  3 iwlagn,iwlcore,mac80211

I'll bet your PCLinuxPOS installation is using an earlier kernel than 2.6.39. You can check on both installations by using the uname -a command. My installation using the 2.6.37 kernel has the following Intel WiFi modules loaded:

Code: Select all

$ lsmod | grep iwl
iwlagn                160149  0
iwlcore                47364  1 iwlagn
mac80211              167330  2 iwlagn,iwlcore
cfg80211              119308  3 iwlagn,iwlcore,mac80211

In the 2.6.39 kernel the iwlcore module is for the legacy 3945/4965 devices (see [PATCH 4/4] iwlwifi: split the drivers for agn and legacy devices 3945/4965), whereas the iwlagn module covers the Intel WiFi devices listed (as I also mentioned in an earlier post).

However, if you look back at one of my earlier posts, you'll notice that the Sabayon 2.6.39-r7 kernel config has:

Code: Select all

meshedgedx src # cat linux-2.6.39-sabayon/.config | grep IWL
CONFIG_IWLAGN=m
# CONFIG_IWLWIFI_DEBUG is not set
CONFIG_IWL_P2P=y
CONFIG_IWLWIFI_LEGACY=m
# CONFIG_IWLWIFI_LEGACY_DEBUG is not set
CONFIG_IWL4965=m
CONFIG_IWL3945=m
meshedgedx src #

so I would have expected iwlcore to show up in the output from lsmod because the config has CONFIG_IWLWIFI_LEGACY=m, CONFIG_IWL4965=m and CONFIG_IWL3965=m. So I'm not sure what is happening. Although I can't see why it would help in your case, I suppose you could try loading the iwlcore module just to see what happens:

Code: Select all

# modprobe iwlcore

[harmon]

Hi!
1.

Code: Select all

sabayon ~ # modprobe iwlcore
FATAL: Module iwlcore not found.


2. Of course I know "uname" :
PCL: 2.6.38, openSuse 2.6.39 (no problem - everything works fine)...
I would like to understand that; if I have time, I'm searching through several forums and see the problems of the user after having installed a new release (half year intervall is no good idea - why not 12 or 18 months?) or a new kernel.

[Fitzcarraldo]

harmon, if you are using another distribution that is also using a 2.6.29 kernel and WiFi works, then I suggest you compare the WiFi settings in the kernel configs (.config file in kernel sources) to see if you can spot anything different.

[harmon]

Hi!
i) I don't know how to see the WiFi settings.
ii) After the last update some packages were removed:
(?attachment quota has been reached?)
A scan is finding my WLAN.
But no connection: A window (Secrets for.. ) opens several times with the right password, I confirm, it opens again...
WLAN interface:
Connection configuring , no IP address, MAC address okay, driver iwlagn, Access Point SSID okay, but
Access Point MAC: 00...00.

Use the zcat command to save the config of a running kernel. See e.g. HOWTO: Upgrade kernel using genkernel for an example of using the zcat command.

Hi!
Thank you, Fitzcarraldo, for your help.
The WLAN problem is solved (BT not):
After the last update the wireless connection was shown again, incomplete, as I wrote. I found out all details, deleted the connection and established again, choosing "connect automatically" and it works again!
I hope, one day, I can return help (in the German subforum, I suppose).
