Ageing commands?

[minthaka]

I remember two years ago, when I issued commands:
iwconfig wlan0 essid ACCESPOINT_NAME and
dhclient
i could connect to the internet opening the browser after them, and everything worked.
Today, I've tried the same thing on Jaunty, but I simply couldn't get ip address.
Are these commands deprecated?

I am running a Jaunty version of mint xfce 4.6 and my wireless connection would drop in and out every few seconds in jaunty with the right module install so I did a

sudo ifconfig eth1 ifup

enter
then

sudo dhcpcd eth1

enter

That was when terminal informed me that dhcpcd was not installed in jaunty so I did a

sudo apt-get install dhcpcd

and rebooted and everything started working correctly. I don't know for sure if that will get you going but it worked for me. I use wicd to connect instead of Network Manager.

As far as I know, dhclient is still the default on Ubuntu. Of course, if you're connecting to an encrypted network, that wouldn't work. You can use iwconfig with WEP networks, but not WPA/WPA2 networks.
