Hello,
I am using Kubuntu 8.04.1 x64 KDE 3.x as my distro running on a Thinkpad T61p. I have both a Intel 4965N Wifi card and a Wired Intel 82566MM Gigabit Network Connection. The strange thing is that my wireless card works fine and has been fine right out of the box. I use Wicd to get on the internet from the Wifi card. I have never used the wired ethernet connection and figured I would check that out. It doesn't work. I plugged the ethernet cable coming from my desktop into the laptop and tried to get onto the internet, but had no luck.
Here is a strange thing I noticed. I went into the system settings in KDE and went to the network settings option and found that my wireless card(wlan0) was enabled while my wired card(eth0) was disabled. No matter how many times I tried to enable the wired card, it would not let me, no error message was dispalyed. When I go into Wicd and connect to my wireless network all of a sudden I find that the wired network card(eth0) is marked as enabled and shows up in ifconfig. If I disconnect from the Wifi network, my wlan0 and eth0 cards disappear from ifconfig. Its as if the 2 are tied together some how??

I want them to work independently. Can any one help me with this problem. I want to use my Wifi sometimes and other times want the wired(obviously not at the same time). Thanks.
