My main problem is that WiFi is pumping on/off.
I don't know is it weake signal, hardware or software problem.
I suppose it is weake signal and software problem.
In earlier ubuntu versions it works better.

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.14 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

Sure, but I am rookie with Linux.
I am not sure what is right package to download.

Harri-vainola, could you please provide the full computer model as noted on the sticker?

[Harri-vainola (harri-vainola)]

In fact my Samsung NP900X4D-K03SE works pretty well, no problems (some
tiny).
- suspend / resume works
- network and wlan works
- after I install linux v3.14 kernel[0], as suggested, I was not able
reboot my computer, so I return v3.13
- after that experiment I got some problems but I am going to clean up
my computer

You can close the ticket.
