I've been trying to find a solution for a problem I've been having with my laptop on 16.04 LTS for a few days now. I can only get the wifi to work after coming out of standby by typing these 2 lines which,as far as I know,reloads the driver for the wifi pcb:

modprobe -rf rt73usb  
modprobe -v rt73usb

I've tried a few methods to try and get this to happen automatically.One was from this thread which gave me this:

!/bin/bash  
case "$1" in  
thaw|resume)  
sudo modprobe -rf rt73usb  
sudo modprobe -v rt73usb  
;;  
*)  
;;  
esac  
exit $

I put this in a file called wakenet, details:

ls -al 

drwxr-xr-x 2 root root 4096 nov 27 16:48 .  
drwxr-xr-x 5 root root 4096 ago  5  2015 ..  
-rwxr-xr-x 1 root root  210 giu 26  2015 10_grub-common  
-rwxr-xr-x 1 root root  660 dic  6  2013 10_unattended-upgrades-hibernate  
-rwxr-xr-x 1 root root 1260 mag 23  2012 novatel_3g_suspend  
-rwxr-xr-x 1 root root  112 nov 27 16:48 wakenet.sh

Please could someone tell me where I'm going wrong because when coming out of standby I still get the same problem? I've only got the basics of what's happening so if you could help I would greatly appreciate it.I guess I've made a fundamental error with the script?Cheers.Mark

  • Can you please check this thread http://askubuntu.com/questions/226278/run-script-on-wakeup – Bidyut Nov 27 '16 at 17:34
  • @Bidyut Tried that but couldn't get it to work.My script was:#!/bin/bash
    case "$1" in
    thaw|resume)
    sudo modprobe -rf rt73usb
    sudo modprobe -v rt73usb
    ;;
    *)
    ;;
    esac
    exit $ I put this in an executable file in this location /usr/lib/pm-utils/sleep.d .Is the above ok?     – user620334 Nov 27 '16 at 19:55
  • Not sure if I understand @Bidyut.The above that I mentioned was in the executable file.Although it's difficult to read. – user620334 Nov 27 '16 at 21:29
  • Ya, you need to put it inside the /usr/lib/pm-utils/sleep.d if you are using Ubuntu 14.04, if you are using Ubuntu release greater than 14.04. – Bidyut Nov 27 '16 at 21:42
  • Yes,that's what I've done @Bidyut,put an executable file,with the above script,in the folder /usr/lib/pm-utils/sleep.d .I'm using 16.04 . – user620334 Nov 27 '16 at 22:21
  • Then you need to implement the resume script for systemd. Regarding that it has been described in the thread. I have not used 16.04 so I don't know much about systemd – Bidyut Nov 28 '16 at 05:10

Many thanks @Bidyut ,that was it!From this I did the following: 

sudo touch /lib/systemd/system-sleep/wakeup  
sudo chmod a+x /lib/systemd/system-sleep/wakeup  
sudo gedit /lib/systemd/system-sleep/wakeup

then used the following script: 

#!/bin/sh  
case $1/$2 in post/*)  
    modprobe -rf rt73usb  
    modprobe -v rt73usb  
    ;;  
esac

Also thanks to @Spmp
