hello,

I tried your repository with my nc10. But the Fn F9-Key does not work correctly! Trying
Code:
sudo nc10 wifi on

in the terminal, I get some error-messages:
Code:
mk@mk-netbook:~$ nc10 wifi
Access Denied - You must be root to perform this operation
mk@mk-netbook:~$ sudo nc10 wifi
WARNING: Error inserting led_class (/lib/modules/2.6.28-15-generic/kernel/drivers/leds/led-class.ko): Unknown symbol in module, or unknown parameter (see dmesg)
WARNING: Error inserting lbm_cw_mac80211 (/lib/modules/2.6.28-15-generic/updates/lbm_cw-mac80211.ko): Unknown symbol in module, or unknown parameter (see dmesg)
FATAL: Error inserting ath5k (/lib/modules/2.6.28-15-generic/updates/ath5k.ko): Unknown symbol in module, or unknown parameter (see dmesg)

Please help me, without your help I can't get online with my netbook!

Micha
(Please excuse my bad english - I know, it's awful!)

Did you install the 'linux-backports-modules-jaunty' package? If so, restart the system.

I think, I did install it, but I'm not sure. Now I can't install anything, because I can't get online with the nc10...

I restarted the system: Now I don't get the error message.
Fn F9 seems to work. But the nc10 don't shows any wlan, even if wifi is on.

What to do now?

Use this command
Code:
iwconfig

and check if 'wlan0' is listed. If so, then the wireless card should be up and running.

Then, try to manually scan for wireless lans, using the command:
Code:
sudo iwlist wlan0 scan

Every 'Cell' section is a found wlan.
The same wlans should be available through the network manager applet in your systray.

It's not listed. Only lo, eth0, pan0 (always with "no wireless extensions.")

mmm, that's strange.

Try to remove then reinsert the ath5k module, with these commands:
Code:
sudo modprobe -r ath5k
sudo modprobe ath5k

and check again if the 'wlan0' is created.
If it's not, check in your dmesg if there is any error explaining what's wrong.

Also, paste here the output of the command:
Code:
lspci | grep Ethernet

No, that changes nothing.

Perhaps it's this:
Code:
[ 1623.976562] ath5k 0000:02:00.0: enabling device (0000 -> 0002)
[ 1623.976578] ath5k 0000:02:00.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16
[ 1623.976599] ath5k 0000:02:00.0: setting latency timer to 64
[ 1623.976720] ath5k 0000:02:00.0: registered as 'phy0'
[ 1623.986789] ath5k phy0: failed to wakeup the MAC Chip
[ 1623.986853] ath5k 0000:02:00.0: PCI INT A disabled
[ 1623.986881] ath5k: probe of 0000:02:00.0 failed with error -5


You find the whole output of dmesg in this file: http://www.bm-kuehn.de/temp/errors.txt (can't attach files here in the board).

Thanks for more help...!

Looking at your dmesg, it seems that the 'ath_hal' and 'ath_pci' modules get loaded during the boot process.
I'm pretty sure this is the problem.
The above modules initialize the wireless card and leave it in a state that the 'ath5k' can't recover from.

The solution is to add these lines to your '/etc/modprobe.d/blacklist.conf' in order to avoid automatic loading:
Code:
blacklist ath_pci
blacklist ath_hal

Let me know if this solves the problem. ;)

No, it's not so good... After another reboot, it does not work again.
The blacklist.conf is unchanged...

What can I do now?

Here is what I did yesterday before I had the problem again:

I installed RandR and tried the Fn F4-Key - it works fine!
Then I installed nc10-fb for the new logo. I restarted the system for have a look at the logo (works fine - thank you)! But now there is no wlan recognized. It seems to be the same problem like before, iwconfig doesn't lists any Wlan0.

The output of dmesg is now here: http://www.bm-kuehn.de/temp/090920-dmesg.txt

Any ideas? It would be great to use the wlan tomorrow...!

Micha

Did you install the madwifi drivers manually?
I ask because ubuntu jaunty does not ship them by default, so they should not be installed.

Looking at your dmesg, it seems that no ath* module get loaded automatically at boot. While this is normal for 'ath_pci' and 'ath_hal' (you blacklisted them), the 'ath5k' should be loaded instead.
If it's not, the only cause I can think of is that the madwifi created some aliases during its installation, "linking" the wireless card to the 'ath_pci' and 'ath_hal' modules, ovverriding the default 'ath5k'.

So, make sure to completely uninstall the madwifi with the command 'sudo make uninstall' from within its sources directory.

PS: In the meanwhile, you should be able to use the wireless card by loading manually the 'ath5k' module.

Yes, I did. That was the first thing I installed in May, while testing ubuntu 9.04. The original drivers did not work with the NC10.

How can I find this folder? And is your driver active after uninstalling madwifi?

How can I load it? (I'm really new at linux...)
Thanks!

I searched for madwifi and found only two files: madwifi.py and madwifi.pyc both in /usr/share/jockey/handlers/.
"sudo make uninstall" does not work (in german: make: *** Keine Regel, um "uninstall" zu erstellen. Schluss", means: no rule for "uninstall". Finish.)
A "sudo make uninstall madwifi" does not work, too (same error).

Hm. You see, I need more help - for a linux newbie.
