Hello and welcome to the forum

Let's take a step back - exactly what wireless AND wired devices does your computer have? Can you post the output of

lspci -nn | grep -e '\[0200\]' -e '\[0280\]'

[chili555]

Yes, please identify your hardware as steeldriver requested.

[davidcholo]

OOOOOOHHHHH!!! Thank you all for your replies, okey i'll do that, but please be patient cause I literally have to boot to ubuntu and boot again to windows 7 to be able to reply,

[davidcholo]

Here is the output.

03:00.0 Ethernet controller [0200]: Atheros Communications Inc. AR8161 Gigabit Ethernet [1969:1091] (rev 10)

We could instruct you how to continue to download dependencies and dependencies of dependencies for several dozen posts and eventually you'd get the driver alx compiled and installed. That assumes you stick with the process for that long and don't get disgusted and go back to Windows.

Or you could install 13.04 and your device would work immediately with no other steps!

What do you prefer? steeldriver and I will help in either case. We secretly hope you pick 13.04 but don't tell anybody! Shhh!

[davidcholo]

well sir, if it what you suggest then I shall go with 13.04,
so now, first i think i have to get rid of my 12.04, any recommendation?

[chili555]

I am not very experienced with dual-boot, but I'd suggest you open Update Manager, and select 'For any new version.' as attached. You should be offered an update to 13.04 and I'd install it.

steeldriver will chime in with his opinion, I hope.

[davidcholo]

mmm. but will I even be able to update without internet?

[davidcholo]

arrrgghh,,,if needed, I think it would be hard to uninstall ubuntu cause I installed it in the windows partition!!! arrrgggghhhh!!! I'm scared now,
