    wireless cant reconnect - dell vostro 1700 intel 3945

    Hi out there,

    I am having strange prob with my wireless network, everything starts fine but after a while there will be a dropout, then sometimes the wireless will come back but other times it seems like the driver has crashed or something and the OS can't talk to the card.

    Then lots of stuff hangs. but after a system restart everything is fine again.

    The problem is that its only staying up for about half an hour at the moment so i can't get much done beetween restarts.

    Even if i do the old:-
    ifconfig
    ifup
    ifdown
    the command line hangs and i cant even use Ctrl+C to quit.

    Does anyone have any ideas? maybe i can restart the module or something but not sure how.

    the command line hangs and i cant even use Ctrl+C to quit.
    I think you have bigger problems than the driver for 3945, perhaps IRQ conflicts, but that's a guess. Here are three diagnostic tools. First, open a terminal and do:
    Code:
    sudo cat /var/log/messages | grep iwl
    Or try:
    Code:
    sudo cat /var/log/messages | grep IRQ
    Next, before you type 'ifconfig' in a terminal, open another terminal and do:
    Code:
    sudo tail -f /var/log/messages
    Leave this terminal open and watch for errors to appear as you 'ifconfig.'

    You might also run:
    Code:
    top
    See what's eating CPU cycles before, during and after you 'ifconfig.'

    I cant see any interrupt conflicts
    Code:
    sudo cat /var/log/messages | grep IRQ
    gives

    I have had /var/log/messages tailed while doing ifconfig, ifup, ifdown and i don't get any output into the log file, weird.

    To me it looks like some sort of resource deadlock, like some resource isn't being released then the wireless connection drops out. So that when i try to reconnect the systems calls are waiting for a resource.
