Hi voria, Something very strange happened, I finally managed to get the wifi working at full speed by building the 2009-04-13 version of the driver, but then after a rebooting, the wifi was gone once more!

I tried everything from changing the settings of the modem, network manager, ndiswrapper, different distros ...

The thing I don't understand is that many people here have that model and it work for them, so why not for me ?
On the netbook, it's written model: np-nc10-ka01fr

And lspci says:
Ethernet controller: Atheros Communications Inc. AR242x 802.11abg Wireless PCI Express Adapter (rev 01)

And my kernel:
2.6.28-11-generic

Do you have the same card ? an what's your model of netbook please ?

Mine is NP-NC10-KA04IT: 04 stands for blue color, IT for the italian keyboard layout.
Your NC10 is exactly the same as mine, except that it's white (01) with french keyboard layout (FR).

The wireless card is exactly the same too, so it's not normal you are having all these problems.

Please remove the manually installed driver ('sudo make uninstall' from inside the compat-wireless sources directory), then install the 'linux-backports-modules-jaunty' package with this command:
Code:
sudo apt-get install linux-backports-modules-jaunty


When done, paste here the output of the command:
Code:
dpkg -p linux-backports-modules-2.6.28-11-generic

Hi, thanks for the answer.

Here is the output:
maike@maike-netbook:~$ dpkg -p linux-backports-modules-2.6.28-11-generic
Package: linux-backports-modules-2.6.28-11-generic
Priority: optional
Section: admin
Installed-Size: 4008
Maintainer: Ubuntu Kernel Team
Architecture: i386
Source: linux-backports-modules-2.6.28
Version: 2.6.28-11.13~ppa6~nc10~jaunty
Depends: linux-image-2.6.28-11-generic
Pre-Depends: dpkg (>= 1.10.24)
Size: 1297760
Description: Ubuntu supplied Linux modules for version 2.6.28 on x86
This package contains modules supplied by Ubuntu for Linux kernel 2.6.28 on
x86.
.
You likely do not want to install this package directly. Instead, install
the linux-generic meta-package, which will ensure that upgrades work
correctly, and that supporting packages are also installed.

I should maybe mention that I've installed kernel 2.6.29-02062901-generic

Meantime I went on samsung website to see the specification of the netbook, it's written AR5007EG, but i've opened the pc and saw AR5bx63 ??
Also noticed on the website, the netbook's picture was a samsung NC10 Sens, I've only got a NC10, not a sens, does it make any difference ?

If you are using a different kernel, then you are not using the wireless driver from my custom package, even if it's installed.
It is for kernel 2.6.28-11 only.

Hi, I uninstalled my new kernel, so I use now : 2.6.28-11-generic

And there is a new version of compat driver : 30-04-2009
This one builds fine, but still i can't connect to wif.

Here is my /etc/modules file
Code:
lp
ath5k


And my /etc/modprobe.d/blacklist.conf
Code:
# evbug is a debug tool that should be loaded explicitly
blacklist evbug

# these drivers are very simple, the HID drivers are usually preferred
blacklist usbmouse
blacklist usbkbd

# replaced by e100
blacklist eepro100

# replaced by tulip
blacklist de4x5

# causes no end of confusion by creating unexpected network interfaces
blacklist eth1394

# snd_intel8x0m can interfere with snd_intel8x0, doesn't seem to support much
# hardware on its own (Ubuntu bug #2011, #6810)
blacklist snd_intel8x0m

# Conflicts with dvb driver (which is better for handling this device)
blacklist snd_aw2

# causes failure to suspend on HP compaq nc6000 (Ubuntu: #10306)
blacklist i2c_i801

# replaced by p54pci
blacklist prism54

# replaced by b43 and ssb.
blacklist bcm43xx

# most apps now use garmin usb driver directly (Ubuntu: #114565)
blacklist garmin_gps

# replaced by asus-laptop (Ubuntu: #184721)
blacklist asus_acpi

# low-quality, just noise when being used for sound playback, causes
# hangs at desktop session start (Ubuntu: #246969)
blacklist snd_pcsp

# EDAC driver for amd76x clashes with the agp driver preventing the aperture
# from being initialised (Ubuntu: #297750). Blacklist so that the driver
# continues to build and is installable for the few cases where its
# really needed.
blacklist amd76x_edac

blacklist ath_pci
blacklist ath_hal


I'm wondering what are your setting in network-manager and in your router's page, do you use wifi G, B or BG and what type of encrytion ? Wpa, wpa2 ?

Thanks.

I'm using network-manager with no special settings... I just select my wlan from the list, insert the password, and I'm online.
My router's wifi is set as BG, with WPA2 encryption.
Please give a try with the new linux-backports-modules package on my repository.
It's updated to 2009.05.01 (today) snapshot for wireless driver.
At the moment it's not available yet, it's in queue to be built. It should be done in the next few hours.

LPIA stands for 'Low Power Intel Architecture', it's similar to i386 but it's optimized for atom processors.
It's the architecture I'm currently using on my NC10.

The build processes for lpia on launchpad repositories have an higher priority than the i386 ones. Usually the lpia packages are built in a few minutes from when I upload the sources, i386 goes in queue for hours instead.

Oops,
can you use LPIA backports-modules, if all the rest of the machine is i386?

Do you get some power consumption benefits by using LPIA? Now, in my nc10, WinXP in second partition consumes 15% less power than jaunty i386 in the first one.

Usually yes, but you have to force apt to accept a different architecture, and this is not a good practice at all. Anyway, the i386 package for 'linux-backports-modules' has finally been built and it is available on my repository.

Actually I can't say too much, because I never used jaunty i386 (well, I installed the beta version but it was used only to test new packages, nothing more), and I can't compare jaunty with my old intrepid system because there are too many differences.
But it seems that the system is slighty more responsive.
Anyway, my advice is to use lpia. There must be a reason if a specific architecture has been created for low power processors. ;)
