network problem when suspending

Hi guys,

I have Linux SuSE 10 installed in a laptop. The network works okay but
it doesn't work after suspending.

I have tried restarting manually the drivers using ifdown and ifup. The
problem is when getting the ip address from a DHCP server. It just look
for a DHCP server and it just says that it can't find any. The strange
thing is that everything is okay when I restart the computer normally.

Does anybody has experienced a similar problem?

thank you....

Ziller,

This is quite typical. You'll probably have to rmmod the appropriate
module(s) as well.

Something like:

ifdown eth0
rmmod eepro100 (or whatever you're using)

If it won't unload you'll have to stop other services and/or rmmod other
modules as well.

then:

ifup eth0

If "ifup" doesn't load the module you'll have to do it with "modprobe"

One thought would be to put these commands in a script to make is
easier. Often X will break when you suspend too. I sometimes just
disable the suspend feature all together.

How about a "rcnetwork restart" (or whatever is used to start the
network services, e.g. "/etc/init.d/network restart") ?

Furthermore it would be pretty much interesting for the developers to
know more about that particular problem (hardware, kernel, drivers).
Could you please report that bug to bugzilla ? You will find more
information how to report a bug under
http://www.opensuse.org/Submit_a_bug and

Never give up !

Scott,

Great, finally the problem was solved with your advice.

once, the computer restarted it is need just to run

rmmod natsemi
modprobe natsemi

and that's it.
It is no necessary to use ifdown and ifup and rcnetwork didn't work.

Now I will make that it be done automatically when suspending.

Thank you again!
