    Default Wlan, Ethernet device and mouse suddently no more available

    Hello everybody,
    I have some problems with Backtrack since I tried to restore the grub installation, which was substituted by that of BT, which excluded all other linux OS installed.
    So I followed the instruction to restore Grub2 and it works! I have now all my OS back inclusive BT4.
    But... neither touchpad nor usb-mouse functioned anymore, and starting /etc/init.d/networking the wlan0 device, which was recognized till that moment, outputted
    Code:
    SIOCSIFADDR: No such device
    wlan0: ERROR while getting interface flags : No such device
    wlan0: ERROR while getting interface flags : No such device
    Bin d socket to interface: No such device
    Failed to bring up wlan0.
    done.
    I put then the live cd in the laptop (Acer aspire 5630) and I see everything works well, so I decided to install BT4 new. I reboot and the issues are still here: no mouse and no wlan.

    Searching in internet I found out how to enable SHMConfig for the touchpad, unfortunately the touchpad is still dead, but the usb-mouse functions again...

    what can I do to get the touchpad and, more important, the wlan0 device working again?

    Greetings

    EDIT:
    when I try to run synclient, the answer is always:" X server supports X Input 1.4. I need 1.5.", I have no idea what this could mean.
    What now concern wlan, this is what I get
    Code:

    One thing to try, check /etc/network/interfaces and make sure it looks something like:
    Code:
    auto lo
    iface lo inet loopback
    
    auto eth0
    iface eth0 inet dhcp
    
    auto wlan0
    iface wlan0 inet dhcp
    
    auto wlan1
    iface wlan1 inet dhcp
    Make sure your /etc/resolve.conf file contains:
    Code:
    nameserver <gateway, ie 192.168.1.1>
    Then type:
    Code:
    ifconfig wlan0 up
    Hopefully that helps get you network interfaces up and going.
