Problem with wired network connection

[Siassei]

Hello,

I installed Fedora 11 on my computer with the live cd. If I run the live cd, the network connection is active. But, after the installation the cannt connect with the wired network. I must use an internal Server to connect the www. The server controlls my mac address and if it correct, the server allow the connection.

ipconfig and the network manager can read the correct mac address. Why it does not work :confused:

OK. It is the KDE networkmanager. If the NetworkManager is disabled then run the Network.

But, I need the Manager for VPN. Why does not the Networkmanager work?
