I have two wireless cards: a Linksys WPC11 .ver 3, and a Netgear MA401, that I'm trying to use to connect to my home wireless router (a DLink, I think, don't have all the specs right now). I have tried several ways, but although the card (either one) is recognized by the system (running Ubuntu 8.04 Hardy Heron version), the network is not. I need specific instructions preferably using the command line (I don't trust the Network Administrator), taking into account that I still consider myself a newbie, and not quite familiar with all the lingo, etc. of using Linux.

I've been to other forums in search for an answer, but still to no avail. Thanks in advance!

To see wireless interfaces: iwconfig [interface]
To start interface : ifconfig [interface] up

Does the following command list the available wireless networks in your area?
Your NIC may be called something other than "wlan0", just do "iwconfig" as mentioned to find its correct interface name.

I'll have to test it at home tonite. At work right now. Thanks for the suggestion. I'll keep posting results.

iwconfig works, but ifconfig <interface> up returns: ACCESS DENIED everytime I try it.

You have to run ifconfig as root or use sudo.

That's what I've done. Still Access Denied.

Yes. My NIC is called eth2, so I'll run the command using eth2 instead of wlan0. I'm aware of that. Thx.
