Bringing Up Wireless Connections Automatically

[Robert L. Cochran]

How do I get Fedora Core 5 to automatically detect and set up my wireless 
connection? I can see that it detects the Broadcom 43xx (I think it's a 
4316) integrated wireless controller, but the runlevel 5 scripts don't 
actually detect and configure the connection with the essid and encryption 
key, then do a dhcp call to get an IP address, the host name, and the DNS 
information.

If I do this manually in a terminal as root:

iwconfig eth1 essid hummr
iwconfig eth1 key open xxxx...
dhclient eth1

The wireless connection comes up and Firefox can visit websites etc. But I 
have 2 problems:

The hostname isn't changed from localhost.localdomain to the one I want for 
this machine (it should be supplied by my dhcp server)
I'm only getting an 11 Mbps bitrate and I know this wireless connection can 
do 54.

and perhaps a third issue:

The connection doesn't seem able to scan for available wireless networks, 
either.

Thanks for any advice that can be supplied. I did look for this information 
on fedorafaq.org and fedora.redhat.com. I also Googled.
