network card and 'suspend'

[trekker92]

hello

since a year, under windows i just suspend my computer the night, and the next day he is working fine, with ethernet.
But with fedora, it's differents :
when i suspend it, the next day, only the green led works. the orange don't light up;
i've tried to plug and unplug the ethernet wire, that do nothing.
i always need to reboot to use network..

i've try this :

[root@HP-PAVILION-DV7-2130SF init.d]# ./network restart


but it's doesn't works.. help me please

WHICH Fedora are you using ?
Which ethernet interface is involved ?
Is this wifi or the wired enet ?

he output of 'uname -a' and 'lspci -vnnk' would be very useful.

Great F16 and an r8169. (I hate the realteks, but they are very common).

The green vs amber LED likely means your interface is set at 100Mhz, not 1G.
This command as root should tell you the speed.
mii-tool eth0
You may need to install the mii-tool binary as
yum install net-tools
You need to use YOUR interface name, which may not be 'eth0'. The command
ip link
shows all the interfaces.


So I suggest you test speed with the mii-tool while it's working and after it's wedged.

If the speed looks wrong - then this command may fix it (again as root)
mii-tool -r eth0

If that doesn't fix it try these two commands as root
modprobe -r mod r8169
modprobe r8169

You can create your own script to patch this up in /usr/lib64/pm-utils/sleep.d, once we know what fixes it.

Probably something like ...

#!/bin/sh
# r8169 hack

case "$1" in
	hibernate|suspend)
		;;
	thaw|resume) 
             /sbin/mii-tool -r eth0
		;;
	*) exit $NA
		;;
esac

hello

thanks you for answering

so i've do that :

[root@HP-PAVILION-DV7-2130SF tkr]# mii-tool p6p1
p6p1: negotiated 100baseTx-FD flow-control, link ok
[root@HP-PAVILION-DV7-2130SF tkr]# yum install net-tools
Modules complémentaires chargés*: langpacks, presto, refresh-packagekit
Le paquet net-tools-1.60-126.fc16.x86_64 est déjà installé dans sa dernière version
Rien à faire
[root@HP-PAVILION-DV7-2130SF tkr]# ip link
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: p6p1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
link/ether 00:23:8b:92:3e:26 brd ff:ff:ff:ff:ff:ff
3: wlan0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN qlen 1000
link/ether 00:25:56:ac:1d:ea brd ff:ff:ff:ff:ff:ff

When i need to load the script? after the suspend?

thanks again

Remember if you use NetworkManager you'll have to enable the Connect automatically option otherwise the network will be offline after resuming untill you manually reconnect.

This is a feature and not a bug ;-)

[trekker92]

hello

thanks for your answer..
the 'connect automatically' option is aleady active..

[george_toolan]

What does dmesg say after resuming? Usually it should look something like this:

[33884.413679] Restarting tasks ... done.

I have had a similar problem with fc 12. Only way the network runs was after a reboot.
Now tried this-
Suspended.
Reset router and waited till it worked - all lights on and blinking
Resumed pc by pressing swith
fedora network restarted automatically
PLEASE DISREGARD THIS DOES NOT WORK ALWAYS
PROBLEM AND SOLUTION IS ELSEWHERE

[nefg]

Final Solution for me was "service NetworkManager restart" from root terminal (not "service network restart"). There are other threads e.g. http://forums.fedoraforum.org/archiv.../t-262356.html which say the same thing.
Main thing reboot is not needed.
