Network doesn't work after standy or hibernate

[wkcchampion]

Hello. I have ubuntu 10.10 on my old desktop, I'm encountering this problem.

If I put the computer on standy or hibernation, the network does no longer work after the system is resumed back!

I tried both the current 28 and the previous 27 kernels, but it occurs anyway.

This computer has only an Ethernet/cable connection to my router. No Wi-fi. The motherboard is an old KV( 3rd eye by Abit.

My netbook has Ubuntu netbook edition and the issue doesn't take place there.

Thanks for the help

[wkcchampion]

bump anyone?

I think you have to try pressing and holding the PC’s power button for five seconds or more. On a PC that's configured to Suspend or Hibernate with a press of the power button, holding down the power button will usually reset and reboot it.

please, a serious answer! That will abruptly power down my computer...

Hi

After coming out of suspend open a terminal and type


sudo /etc/init.d/networking restart

Enter your password. It will not be echoed to the screen. Does that bring it back up ?

Kind regards.

Hi Matt,
I tried your solution. Unfortunately, it doesn't seem to work.

This is what appears in the terminal:



marco@casa:~$ sudo /etc/init.d/networking restart
* Reconfiguring network interfaces... Ignoring unknown interface eth0=eth0.
[ OK ]
marco@casa:~$


The network is still down after I've launched the command.

Hi

Please post the output of (case sensitive)


lspci -nnk | grep -A3 Network

EDIT: Hold on i have just realised you only have a wired network connection

Try this one instead.


lspci -nnk | grep -A3 Ethernet

Kind regards

Yes i was editing my post. I did not realise you had an ethernet connection and no wireless connection.

Please post

Hi

After suspend on resume, open a termina and type


sudo rmmod via-velocity
sudo modprobe via-velocity

What are your connection speed like after that ?

Kind regards

it works. The network gets back working. Any way to do this automatically on resume?

Yes, but i will not be able to look at this for a couple of hours.

I cant remember the exact file to put it in. I think it's one of the acpi configuration files but i will need to check.

Bump this thread so it appears in my user_cp area and i will be able to find it.

Kind regards

Hi

Can you post the output of


cat /etc/default/acpi-support

between code tags.

Kind regards

Hi

Can you post the output of

marco@casa:~$ cat /etc/default/acpi-support
#
# Configuration file for the acpi-support package
#
#
# The acpi-support package is intended as "glue" to make special functions of
# laptops work. Specifically, it translates special function keys for some
# laptop models into actions or generic function key presses.
#


#
# Suspend/hibernate method
# ------------------------
#
# When gnome-power-manager or klaptopdaemon are running, acpi-support will
# translate the suspend and hibernate keys of laptops into special "suspend"
# and "hibernate" keys that these daemons handle.
#
# Only in situations where there is no gnome-power-manager or klaptopdaemon
# running, acpi-support needs to perform suspend/hibernate in some other way.
# There are several options for this. The options are:
#
# dbus-pm:
# Perform suspend and hibernate actions via a DBUS request to the power
# management daemon. This works for power management daemons that we don't
# know of. (For gnome-power-manager and klaptopdaemon this will do nothing,
# since those will be detected when they are running, and triggered using
# a virtual keypress.)
#
# dbus-hal:
# Perform suspend and hibernate actions via a DBUS request directly to HAL,
# bypassing any running power management daemons.
#
# pm-utils:
# Use pm-suspend and pm-hibernate to suspend and hibernate. (The dbus method
# normally results in this as well, but calls through dbus. Use this option
# only if you don't have dbus installed.)
#
# hibernate:
# Use the hibernate package to suspend and hibernate.
#
# acpi-support:
# Use the legacy built-in suspend/hibernate support. (DEPRECATED)
#
# none:
# Do not attempt to suspend/hibernate. Set SUSPEND_METHODS="none" to
# disable suspend/hibernate handling in acpi-support.
#
# If you specify dbus or pm-utils, the result will normally be the same as when
# you suspend from your desktop environment. If you specify "hibernate" or
# "acpi-support", be aware that this probably does not match what your desktop
# environment would do (unless you have managed to configure something so that
# the DBUS power management interfaces call the hibernate package).
#
#
# Please specify a space separated list of options. The recommended value is
# "dbus pm-utils"
#
SUSPEND_METHODS="dbus-pm dbus-hal pm-utils"



#
# LEGACY BUILT IN SUSPEND SUPPORT (DEPRECATED)
# --------------------------------------------
#
# These options only work for the "acpi-support" suspend method. This is NOT
# recommended, but is retained for backward compatibility reasons.

# your machine on hibernation

Hi

That looks good.

I can't actually track down the info i read on this so this might not be the correct technique but it's worth a try. If not we can try something else.

I think this is what we need to do.

Open a terminal and type


sudo nano /etc/pm/10-wireless

Enter your password as normal.

Type


SUSPEND_MODULES="via-velocity"

Ctrl + o to save and ctrl + x to exit.

Suspend and resume.

Kind regards

nope :(

[matt_symes]

Hi


nope :(

Don't worry. We'll fix it.

I might have to look at this tomorrow though. I have a party to go to very soon.

Remove that file you created.

Kind regards

[matt_symes]

Hi

Try this. Create a file called /etc/pm/sleep.d/10_wireless_sleep


sudo nano /etc/pm/sleep.d/10_wireless_sleep

Add this code.


#!/bin/sh

if [ "$1" = "suspend" ]
then
modprobe -r via-velocity
fi

if [ "$1" = "resume" ]
then
modprobe via-velocity
fi

Make the script executable


sudo chmod +x /etc/pm/sleep.d/10_wireless_sleep

Suspend and resume.

If that does not work there is something else we can try. If it does work we can clean up the script tomorrow.

Kind regards

It works - the machine is online after the resume. I did a bandwidth test and the speed looks normal. I think it is solved!
Maybe take a note on this for future kernels

[matt_symes]

Hi

It's not the best script in the world. It was just more for testing.

If you want a better updated script reply and i will post one. I may post one anyway.

Glad it's fixed though.

Kind regards

Well, ok then... post one as u have time Does that script make my computer "believe" that the wifi has morphed into an ethernet connection?

:D No morphing. I will post it in a couple of hours. It will give me something to do on a Sunday morning.

Hi

Try this script. It should handle both suspend and hibernate.


#!/bin/sh

case "{$1}" in
suspend|hibernate)
# Unload via-velocity
modprobe -r via-velocity
;;
resume|thaw)
# Reload via-velocity.
modprobe via-velocity
;;
esac

Call it the same name as before and make sure it's executable with chmod.

Kind regards

case "{$1}" in
suspend|hibernate)
# Unload via-velocity
modprobe -r via-velocity
;;
resume|thaw)
# Reload via-velocity.
modprobe via-velocity
;;
esacCall it the same name as before and make sure it's executable with chmod.

Kind regards
This one doesn't work. shall i get back to the old one?

[matt_symes]

Hi

I'll test it now. Maybe i should have done that first. Wait for a little while and i will get back to you.

Kind regards.

[matt_symes]

Hi

Try this.


sudo nano /etc/pm/sleep.d/10_wireless_sleep

copy and paste this


#!/bin/sh

case "$1" in
suspend|hibernate)
# Unload via-velocity
rmmod via-velocity
# touch /home/matthew/suspending
;;
resume|thaw)
# Reload via-velocity.
modprobe via-velocity
# touch /home/matthew/resuming
;;
esac

make it executable.


sudo chmod 751 /etc/pm/sleep.d/10_wireless_sleep

You can test to see if it's being called by removing the # infront of the touch /home/matthew/..... commands and changing matthew to your user name.

That created the two files in my home directory after hibernating.


matthew@matthew-laptop:~$ ls ~/*ing
/home/matthew/resuming /home/matthew/suspending
matthew@matthew-laptop:~$

Hopefully that will fix it for you.

Kind regards

[wkcchampion]

it did it! Thank you!

If everything else fails, use the following script which unloads and loads all module in your system. Remember this script is dangerous to use on production and use it at ur own risk.
Also It may not work for you, but it worked for me. Just my 2 cents.


#!/bin/bash

lsmod >./lsmod.txt_everythingworking
cat ./lsmod.txt_everythingworking | while read LINE
do
MODULE_NAME=`echo $LINE | awk '{print $1}'`
sudo rmmod $MODULE_NAME
sudo modprobe $MODULE_NAME
done
