I have an icon "wlan reset" setup as following:

a file /usr/share/applications/wlan-reset.desktop containing:

[Desktop Entry]
Name=wlan reset
Exec=sh -c "exec /path/program"

as devel-su created a script

rmmod wlan
sleep 20
modprobe wlan

script with setuid bit:

chmod 4755 <script>

c code from setuid on shell scripts

#include <stdio.h>
#include <stdlib.h>
#include <sys/types.h>
#include <unistd.h>
int main()
   setuid( 0 );
   system( "/path/script" );
   return 0;

compile the program:

gcc <c code> -o <program>

program with setuid bit:

chmod 4755 <program>

et voila a wlan / wifi reset without rebooting

Both with the icon and the commandline is that wlan status icons most of the time does not get updated.

Thank you! I needed this. Now I see there is an app based on this solution on OpenRepos: Wlan reset

Thanks! Shouldn't it use "modprobe -r" instead of rmmod? "man rmmod" says so.
