    gives 0: acer-wireless: Wireless LAN

    Hard blocked: no

    Code:
    dmesg | grep wl
    Gives no output, only returns to prompt.



    My machine is now having trouble shutting down as well. I guess I should start another thread for that after the WiFi is working again, though.

    Let's try a bit harder:
    Code:
    sudo modprobe -r b43
    sudo modprobe wl
    dmesg | grep wl

    Code:
    sudo modprobe wl
    was interesting. The, now expected, no output return to prompt occured. Then a message appeared on the desktop informing me that a conection to my network had been established. I have no idea what happened, as I don't quite understand what modprobe accomplishes. I hope it will tell you something that can help you! The network connection seems to be stable now but ifconfig still does not list any 'wlan' interface.

    Code:
    dmesg | grep wl

    After reboot the WiFi connection didn't return. I tried to repeat the process that seemed to have caused the connection to be established before but it didn't work.

    Hi, the driver you are using..wl produces eth1 (usually)
    not wlan#, wlan0 or wlan1 is usually seen with the b43 driver
    so not seeing a wlan# is normal.
    please do..
    Code:
    sudo modprobe wl
    then do..
    Code:
    cat /etc/modules
    cat /etc/modprobe.d/blacklist.conf | grep blacklist
    lsmod |egrep 'b43|bcma|ssb|wl'
    thanks.

    ah ha !

    cat /etc/modules lp b43

    that is loading the b43 driver,let's fix that
    please do..
    Code:
    sudo gedit /ect/modules
    backspace out b43 (remove)
    and replace with wl
    it should now look like this
    lp
    wl
    click save and close gedit
    then boot.

    That did the trick! WiFi is working normally now! I would have never figured that out on my own. Well maybe some day but it would have been long after I had reinstalled the entire OS to try to fix the problem! Thanks a lot!

    So now my most immediate question has to do with kernels/modules/drivers... I am wondering if I am begining to understand this... A module is a section of the kernel which calls on a driver file and loads it at startup. Is that close? Are modules discrete pieces of software in the kernel, or is the word module just used to identify a generic/common part of the kernel whose job is to load/start things like drivers when the OS boots? I have a lot of other questions too but I will need to go back and read the thread to remember those.

    Also, am I correct in thinking that the problem with my wifi boiled down to the fact that a module had been programmed to load a driver that does not work with the broadcom 4313, and that reprogramming the module to load the lp driver in place of the b43 was what got the wifi working again?

    I will be looking for instructions on how to do several things with Ubuntu. If I can not find answers for my questions already posted in this forum, I hope you and your friend Chili555 can participate in the solutions!
