Please attach here the output of the following commands:

Code:

lspci -nn

Code:

sudo dmidecode -s system-product-name

PS: Thread moved to the 'linux' forum, as it's not an hardware problem.

Hi
Thanks man everything worked out exactly said...

I did only the installation. But i want to ask if i should prevent system from upgrading kernel?

Also there is one flaw left, considering the gravity its minor but my wireless lan light is still not going off when wireless gets disabled. This was just for info, it doesn't bother me.

anyways thanks a ton for making my day...

I think this is not a good idea. If new kernels are released, there is a reason.

Anyway, you can block any package from being updated using the graphical package manager. Select the package you want, then go to 'Package'->'Lock Version'.

Assuming you are using 'samsung-scripts', by default wireless is disabled by using the 'iwconfig' command line utility. This works good on NC10, where radio is turned off when setting transmit power to 0, but it might not work with other models.
Try to edit the file '/etc/default/samsung-scripts', and change 'WIRELESS_TOGGLE_METHOD' to 1, and 'WIRELESS_MODULE' to "ath9k" (the driver used by your wireless card).

i did the edit and am trying this option without restart, light is still not going off.

leave it i don't want a fix for it ... guess nothing is perfect...

thanks a ton

voRia · **Posted:** 25/03/2010, 18:02

Well, I don't know if the ath9k module has support for rfkill (ie, a way to physically turn off the wireless radio). If it lacks this support, there is no way to turn completely off the wireless card by using the current 'samsung-scripts' package.

Anyway, with lucid I will release a new package in its place, 'samsung-tools', which among other things, has support for the new 'easy-slow-down-manager' interface, providing a better and more general way to turn off the wireless card (it should work independently of the wireless card model in use).
If you want to try it on karmic, you can follow the instructions in this thread.
