I have recently installed Ubuntu 10.04 beside my Windows XP on my laptop: Dell XPS 1330

I`m now facing some problems with my new OS :

  1. The driver for my wireless network card isn't recognized although I have installed the recommended driver which was in Ubuntu Hardware Driver section.

  2. When I connect my laptop to my TV using HDMI port, the screen is OK but there is no sound!

  3. When by any reason my network cable is unplugged, the whole network service goes down and I have to restart the system.

Thanks in advance for your helps.

I'm unable to dig up further Hardware-Specs for that laptop, can you please add the output of lspci and aplay -l (in code tags) to your question? –  Bobby Sep 27 '10 at 10:30
    
Have you ever upgraded the BIOS? In my case (Dell Latitude D830) the original BIOS version (A02) was almost unusable; docking/undocking froze everything, WLAN could see the access points but not connect them, suspend/resume was buggy... all this with Windows 7, Ubuntu, Debian, openSUSE and PC-BSD. After I upgraded the BIOS to latest version (A14) everything started to work. –  Janne Pikkarainen Sep 27 '10 at 12:49
    
I have also a Windows XP beside my Ubuntu and I have no problem there, But yes you are right It can see the access points but cannot connect to them. Do you think the BIOS might be the problem although there is no problem in my XP? –  Saba Jamalian Sep 27 '10 at 13:12
    
I don't see an audio controller for your HDMI connection in the lspci output, only the on-board audio. What device does XP use for HDMI audio? –  Ignacio Vazquez-Abrams Sep 27 '10 at 13:24
    
I think it uses my graphic card itself. –  Saba Jamalian Sep 28 '10 at 9:22
