I'm new to Ubuntu and Ubuntu server. I found somewhere that I could enable my wifi card with
ifconfig wlan0 up line, and it does. Now it seems like I'm connecting to a network using the line
sudo iwconfig wlan0 essid XXXX key xxx, what else do I need?
I found that I need to "start up" the connection with dhcpcd program but command line replies that dhcpcd can be found in some packages which I can not install using the command
apt-get install dhcpcd. Any ideas?
