help connecting wireless card to AP


I am new to wireless linux.

I am attempting to connect my wireless interface to my AP.

1st I enable the wlan interface:
ifconfig ra0 up

2nd I scan nearby APs:
iwlist ra0 scan

3rd I attempt to connect to wireless AP (i'm assuming this is where I am missing something vital.):
iwconfig ra0 mode managed key s:mypassword ap 00:60:1D:01:23:45

The link light on the card does not turn and `dhclient ra0` does not receive any response to the sent DHCPDISCOVER.

more info:
card - ralink chipset; belkin pc card 'N Wireless Notebook Card' F5D8013
ap - netgear (dont know model off hand & not at home) B/G wireless router
ap is using WPA security

Any help is appreciated.

First disable security on the router and make a plain non secure connection. See if you can do that.

You need wpa-supplicant on your Linux box. If that is installed, you should be able to configure security to match the WPA settings on the router.

I don't know if wpa-supplicant comes installed on your distribution or not.

Hello Hewson

I'm using wireless with Fedora 8 and can give you some pointers with that if it is what you are using. CentOS is going to be quite different though as it doesn't contain all the extras Fedora does to ease the process and I can't help you with that.

Post back if it is Fedora and tell if you are using Gnome or KDE for your desktop and if you installed from the DVD or a live cd. Surprisingly, Fedora sets itself up differently for each of those options.
