Good day,
I have had this strange problem with openSuse for a while: internet would randomly go down, getting back after unplugging and re-plugging the Ethernet cable.
I am positive it is not an hardware issue, because this never happens with Windows 7.
Since today my connection is not working anymore. I get a few seconds of web and then… nothing, not even the router admin page (192.168.1.1).
I was using ifup to connect, and the settings cannot be wrong, since I have another PC with the same hardware on the same network with same Suse version and same configuration working fine.
I’ve googled a few tests I could run by myself to see if something was wrong and I found this post. So I’ve tried.
# rcnetwork restart
Gets me about half a minute of internet connection, enough to load a page or download a few RSS feeds from Thunderbird. Then internet dies.
So I continued:

I don’t know what was I expecting, but I’ve done some pinging…
# ping -c1 130.57.66.6

I wasn’t using any particular nameserver…
# grep -v ^# /etc/resolv.conf
search CASA

After all this I’ve tried switching to NM (I’m on KDE). When I do rcnetwork restart I don’t even get enough time to log in to the router admin page, internet dies in a few seconds.

The others are the same.
This is quite upsetting, I can’t spend my time restarting rcnetwork every 40 seconds. Any more tests I should run to get useful info?
Please help me get my internet back!
