I have installed Linux for the first time and Mdk10 official is the only version I have ever seen. So, I have never seen any other version. For 10 you pick Configure Computer/Network Internet/Manage connections. At this point a dialog about eth0 is displayed. You can change the IP address, DHCP, etc. There is a tab 'Options' and it has a check box labeled 'Network Hotplugging'. I had to uncheck it to fix my problem. Another use told me you can get the same effect by editing /etc/sysconfig/network-scripts/ifcfg-eth0 and adding/modifing these line ONBOOT=yes MII_NOT_SUPPORTED=yes I have no idea what those lines mean or if they work. HTH...David One of the nice things about Linux is that all configuration is by clear text files. No messing about with arcane registry entries is required. When you set that box in the GUI to disable 'Network Hotplugging' what the GUI does is write MII_NOT_SUPPORTED=yes into the configuration file for that interface. You can learn an awful lot about Linux by exploring the configuration files in the /etc folder, but of course for a newbie it is awfully conforting to be able to use a GUI to configure your system. Network Hotplugging is a daemon which looks for Ethernet heartbeats. Most Ethernet cards are able to detect electrical signals which indicate that there is another ethernet device on the other end of the cable (MII). If Network Hotplugging is enabled your system will automatically up an interface when the heartbeat is detected, and will down it if the heartbeat disappears. This is especially good for laptops because it means you can just plug in the Ethernet cable, and within a few seconds you are connected to the network. The downside of hotplugging is that there are a few devices which will get confused and end up in the wrong mode, and some devices do not support it at all. Hence the ability to disable it. derek -- www.jennings.homelinux.net http://twiki.mdklinuxfaq.org Want to buy your Pack or Services from MandrakeSoft?

Turning off 'Network Hotplugging' in MCC networking fixed it. One poster mentioned you could get the same effect by setting MII_NOT_SUPPORTED=no in /etc/sysconfig/network-scripts/ifcfg-eth0.

After a boot you could run dmesg which dumps the last load of system messages on your screen. Might not show enough though. You can also, as root, examine /var/log/messages and /var/log/syslog to see additional information that surrounds loading the driver for your LANcard. Use 'less' for checking the files, it makes scrolling and searching easy. :) Paul -- Breeding rabbits is a hare raising experience. http://www.nlpagan.net/linux.htm Have you visited http://twiki.mdklinuxfaq.org yet?
