Thread: no wireless after resume from S3

  1. #1

    Default no wireless after resume from S3

    Open Suse 11.1, Linux linux-ma5q 2.6.27.23-0.1-pae
    wireless card = BCM4328
    driver = broadcom wl
    system = Compaq 6715b

    On resume from S3 the wireless will not connect.
    iwlist scan shows my network so I think the wireless card works.
    killed NetworkManager as root
    restarted NetworkManager& and now wireless connects.

    maybe this will help someone

    I see the same problem on my site. The reason is that the dhclient isn't started.
    Does anybody know how it should work after resume?

    I was just going to open a thread because of this problem. I have it since last week. The only work around I found was to start my laptop with the wifi switch off, and then turn it on once Suse (11.1) is up an running. I have this problem with KDE & Gnome.

    ...Any help with this will by much appreciated!

    Pm-utils - openSUSE

    Either adding the kernel module to the list of "SUSPEND_MODULES" or creating a custom hook which

    a) reloads kernel modules

    and/or

    b) restarts network services

    will most likely solve the problem.

    thanks for advice.

    "adding the kernel module to the list of "SUSPEND_MODULES"" I have no idea how to do it and where? edit hook called modules ?

    as for modules reload i post my "50modules" hook that is present in pm-utils, is it enough?
    Code:
    #!/bin/bash
    
    . /usr/lib/pm-utils/functions
    
    suspend_modules()
    {
    	[ -z "$SUSPEND_MODULES" ] && return 0
    	for x in $SUSPEND_MODULES ; do
    		echo "trying to unload: $x"
    		modunload $x
    	done
    	return 0
    }
    
    resume_modules()
    {
    	[ -z "$RESUME_MODULES" ] && return 0
    	for x in $RESUME_MODULES ; do
    	 	echo "trying to reload: $x"
    		modprobe $x
    	done
    }
    
    case "$1" in
    	hibernate|suspend)
    		suspend_modules
    		;;
    	thaw|resume)
    		resume_modules
    		;;
    	*)
    		;;
    esac
    
    exit $?
    and as for restart of network service hook: what number should it be and should it be something like: /etc/rc.d/network restart
    I would appreciate your help alot .
