Yes, it is the at76c503 driver.

I do not follow you. Do I need the image? Could you explain to me what's a
firmware image and then whether I need it to connect?

Yes, in my case it defaulted to open, but I'll do what you say and see.

I have the configuration file ifcfg-wlan0 in /etc/sysconfig/network-scripts,
and it seems the network configuration utility made it correctly. The thing
is that if I got the error we have been talking about, and then when it's
time to get the IP information I got it "done", I would be connected, but I
always get: "failed". Anyway, thanks for your feedback.
