    No wireless in my ubuntu 12.04 laptop

    I have recently installed the ubuntu 12.04 on my dell inspiron 15R through wubi inside windows ultimate 64 bit.
    But I cannot see any wireless network as the network icon shows no notifications regarding wireless connection.
    May be the driver is not working.
    I have searched other threads on other sites and follow a thread to unistall bcm-kernel-source and then install the firmware-b43-installera and b43fwcutter .
    But it didn't work.
    here is the results of lspci -vvv
    Code:
    $lspci -vvv

    I did the fresh install of ubuntu and follow your instructions but still to see any wireless connection. The network icon is not showing anything about wireless.

    Re: No wireless in my ubuntu 12.04 laptop

    Did you try wiring it to get internet then getting a new driver.
    Or look on the ubuntu for dells section on this site maybe it will help. There is something with dell laptops.

    Ethernet is working just fine but no wireless
    Bluetooth gets on but no wireless and the rutilt wireless manager says no wireless interface.
