    Pls HELP, no internet connection, lan or Wlan

    hallo everybody

    Internet not working in wireless and LAN cable
    in my new laptop
    Lenovo G580, i5, 3210M, win7
    i installed fresh Ubuntu 12.04 beside the Win7

    also more other versions of Ubuntu, Xubuntu
    and Kubuntu live CDs are the same case.

    both working automatically and perfect in Mandriva 2011 live CD and Win7

    in the first, after installing Ubuntu the wireless was working but very
    weak and always stop and asking for password and don't accept it and never
    comeback till i restart the Ubuntu and so on, but now
    nothing working entirely with Ubuntu , the LAN cable or WLan

    p.s.

    i saw that driver name of Wlan in win7 is different like follow
    (win7)
    Broadcom 802.11n network adapter
    (ubuntu)
    Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller (rev 01)

    please help me to fix this problem
    thanks

    The Win and Ubuntu output both indicate the same card, the Ubuntu output just has more detail so no problem there.

    Please run and post:
    Code:
    lspci -nn
    Tell us the exact details of your wireless device. Also, get your install CD ready to go in case we need it.

    Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller [14e4:4727]
    This device uses the Broadcom proprietary driver. Please drop your install CD in the tray and navigate to pool > restricted > b > bcmwl and drag and drop bcmwl-kernel-source to your desktop. Now navigate to pool > main > d > dkms and drag and drop dkms to your desktop. Now let's reinstall from the terminal:
    Code:
    sudo dpkg -P dkms
    sudo dpkg -P bcmwl-kernel-source
    sudo dpkg -i Desktop/*.deb
    Now see if the driver loads:
    Code:
    sudo modprobe wl
    Is it now working?

    Re: Pls HELP, no internet connection, lan or Wlan

    dpkg: warning: there's no installed package matching dkms
    dpkg: warning: there's no installed package matching bcmwl-kernel-source

    and then the rest lines working ok
    but nothing happened , i restart, also nothing.

    i wanna mention here that the wireless icon already in sys-try shown and wl is ON but he can't see any routers however there are 2 routers around

    Re: Pls HELP, no internet connection, lan or Wlan

    Let's see the result of these commands:
    Code:
    sudo modprobe wl
    dmesg | grep wl
    rfkill list all
    The pipe symbol | is on the right side of my US keyboard on the same key with \. Thanks.

    May we see:
    Code:
    lsmod | grep -e b43 -e brcmsmac -e ssb -e wl
    sudo iwlist wlan0 scan
    Generally, the wireless interface created by bcmwl is eth1, not wlan0.
