    Yet another can't connect to wireless...

    I just installed Ubuntu last night and have thus far not been able to connect to wireless. No connections are shown. I've installed ngisdtk, but I need the .inf files and I'm not sure where to get them. Because every thing I've read has asked the poster for it, here is the dump from sudo lshw -C network:

    uninstall ndiswrapper completely and blacklist the module brcm80211:

    sudo modprobe -rf ndiswrapper
    sudo apt-get remove --purge ndiswrapper-common ndiswrapper-utils-1.9 ndisgtk
    sudo rm /etc/modprobe.d/ndiswrapper.conf
    sudo rm -r /etc/ndiswrapper/* 
    echo "blacklist brcm80211" | sudo tee -a /etc/modprobe.d/blacklist.conf
    sudo depmod -a
    Reboot and install the Broadcom-STA-driver vie cable under "additional drivers"
