    bcm4234 connection on 12.04 but no internet

    Hello all
    I have through this forum gotten as far as installing ndiswrapper loading driver and getting connected to wifi. my issue is now i cant seem to stay connected to internet. will only work for about a minute after i first turn my desktop on. wifi connection never fails just no internet available. any suggestions would be greatly appreciated. thank you in advance.

    I highly doubt that ndiswrapper is the best method to get this going. Please open a terminal and run and post:
    Code:
    lspci -nn -d 14e4:
    rfkill list all
    Thanks.

    Very interesting! Let's widen the search:
    Code:
    lspci -nn
    lsusb
    Thanks.

    Oh, that Broadcom! You had me confused; you said Broadcom BCM4234 and the device is BCM4323. That device does, indeed, only work with ndiswrapper. Let's find out why it isn't:
    Code:
    sudo modprobe ndiswrapper
    ndiswrapper -l
    dmesg | grep ndiswrapper
    Please post the outcome of each command. Thanks.

    Perfect so far! Now how about:
    Code:
    iwconfig
    sudo iwlist wlan0 scan
    rfkill list all
