I tried to install debian on my laptop but there where some problems with my wireless network card. I can't disable it so I installed debian without any network. But now I want to use my standard wire network card, so my question is how I install that through the terminal.

I have no experience with debian before so I have no idea how to do it.

First thing to check is to see whether the system has picked up the network card and initiated the driver which you will find by looking at /var/log/dmesg.
If it found the card then you can setup the network. Edit the file /etc/network/interfaces. If you are going to use dhcp then enter;

auto eth0
iface eth0 inet dhcp

if you need a static address then do;

auto eth0
iface eth0 inet static
address <ip-address>
netmask <ip>
gateway <ip-address>

To start the network open a terminal as root and do;

/etc/init.d/networking start
