There are lots of similar questions, but i think my case is different because of a driver issue.

So the problem is that my laptop cannot connect to wireless network (cannot test for wired) after the last upgrade to 12.04 version. During the upgrade I received an error:

    Preparing to replace linux-firmware 1.79.1 (using .../linux-firmware_1.79.14_all.deb) ...
    Unpacking replacement linux-firmware ...
    dpkg: error processing /var/cache/apt/archives/linux-firmware_1.79.14_all.deb (--unpack):
    trying to overwrite '/lib/firmware/ar3k/AthrBT_0x31010000.dfu', which is also in package bt-dw1705-firmware 0.1
    dpkg-deb: error: subprocess paste was killed by signal (Broken pipe)

As this package is responsible for the wireless network, I think the problem is here. Of course I searched it, but none of the suggested solutions worked (couldn't try some without internet). I also checked the other threads only about the update with no effect.

Some diagnostics frequently asked for:

Try this: askubuntu.com/questions/425583/… It worked for me yesterday. –  user296844 Jun 23 at 22:56
    
Try sudo modprobe ath9k if it works I will put it in an answer. If not do you have the tools installed needed to compile a new driver? What is wrong with your wired connection? Can you tether to your cell phone? –  Wild Man Jun 24 at 0:00
    
The driver for your device ath9k doesn't require firmware. –  chili555 Jun 25 at 12:42
    
@WildMan I tried it, and although lsmod listed after adding it, there wasnt any change in the networking. Does that mean it worked? Anyway, I'm not sure about the compiler tools (note that I'm quite new to ubuntu). I dont know anything about the wired connection, it may be good or bad too, I simply wasnt able to try it. By the way I found out that during the update there was an error saying "oem-wireless-ath9k-3.9-rc4-2 kernel module failed to build" which seems relevant. –  vzsm Jun 26 at 20:44
    
Do you have a computer that came preinstalled with ubuntu? What did you upgrade from? Did you install a new kernel? With the driver loaded please run the script that is in the accepted answer in the link below so we may see the information needed to help diagnose the issue. <askubuntu.com/questions/425155/…; –  Wild Man Jun 26 at 21:21
