I installed the .rpm but where is the file I click to configure everything?
I don't really know what you mean... if it's the iwconfig stuff you can either do it in a terminal as root (after you've installed wireless-tools that is) or you can install xvconfig but then you have to find an rpm for that program.
It's actually quite easy to do it from a terminal:
0. su to root
1. First make sure your card is supported (that you have a driver that works and is up running)
#iwconfig wlan0 key restricted XXXXXXXXXX (if you have encryption)
#iwconfig wlan0 essid ConnectionPoint (where ConnectionPoint is the name of the CP)
2. type #iwlist wlan0 scan
(if the intercae is wlan0 which it probably is)
then you'll get an output which will determine if you can find a CP.
If you don't get an output saying "wlan0 No scan results"
then your card probably works and if you've enter everything right you just have to fix the ip.
I was a bit confused when you started to talk about your ISP. How is your network set up? If it is like mine:
The "ISP-cable" (where I get my internet from) is put into my router and my laptop has a wifi card that connects to the CP in the router.
If it is like that and you have a dhcp server running on the router you can just type:
or if you use dhclient and don't have dhcpcd
If it's not, let me know and I'll tell you how you set up your ip, but if you have a dhcp server running and everything works, you can learn another time about setting your ip =)
