eth0 works... only 10 minutes. Solved (?)

[pep]

Yes, i have a CNet PRO200WL PCI NIC with Davicom / Tulip chipset connecting my machine to the Xavi router from my ADSL provider. Nothing more, apart the splitter that connect also my phone.
So i did the magic suggested here and founded in

http://www.ubuntuforums.org/showthre...hlight=davicom

add "dmfe" without the quotes to /etc/modules
add "blacklist tulip", without the quotations, in /etc/modprobe.d/blacklist

Now the connection starts and stay on for ... 10 minutes
the network settings from the system settings panel are read automatically at startup and display the same values of the windows side. But sometimes they disappear until the next reboot, when the connection works... for the following 10 minutes.

what follows is all the information that could be relevant to someone less naive then me

hope on help.

Re: eth0 works... only 10 minutes. Solved (?)

MANY THANKS for your help. I had exactly the same problem and followed your link -

http://www.ubuntuforums.org/showthre...hlight=davicom

I'd like to add that as a newbie it took me a while to discover that Kubuntu doesn't have gedit - it uses kwrite. Obvious to some more experienced users but not to me! I changed gedit to kwrite and voila! - a working internet connection!

Thank you again.
