I've just started using Ubuntu 12.04.1 LTS on my Alienware M14x. And I'm having some trouble.
The wifi keeps disconnecting every 5 to 15min. I've read a lot about this on the Internet, but the only solution I found didn't work for me (it was to deactivate the IPv6).
And the other problem is that my battery life is really short since I have a dual-boot Windows 7 and Ubuntu. On Ubuntu it lasts 3 hours maximum!!!
So I'm really new to all this stuff, I know I have to give you a lot more details but I just don't know what. So if someone is kind enough to help me, I'll do anything .
Thank you in advance.
