Solution to problem 1:

When you installed Linux, you probably didn't install the kernel source and make tools. If you're running redhat/fedora, you can easily install these. Go to Redhat Menu --> System Settings --> Add Remove Applications. Scroll down to the development section, and check the options for "Development Tools" and "Kernel Development" (I'd actauly check all of the development tools if you have room on your hard drive). This should install your kernel source, and create all appropriate links to /lib/modules.

Solution to problem 2:

Since you have the same card, then the bcmw15a.inf driver in the AR folder should work. That's the one I used.

Yeah, I tried the RPM too, and usually that's easier than compiling a program from source, but in this case the RPM is specific to your kernel version.

I have to say thank you so much. I finally got it working. I have downloaded 3 diffrent distributions and got it to work on the RedHat Enterprise 3.0 following you instructions. I was going to load Fedora Core 2 but i did a bad load once and it kept locking up. Which Distribution are you running? Thanks again, Jay

Awesome!
 

No problem. Glad you got it working.

Retaining configuration
 

OK here is what I did to make my config active when I boot everytime
/etc/sysconf/network-scripts/ifcfg-wlan0

_______________________________________________
# Please read /usr/share/doc/initscripts-*/sysconfig.txt
# for the documentation of these parameters.
ONBOOT=yes
USERCTL=no
PEERDNS=yes
GATEWAY=
TYPE=Ethernet
DHCP_HOSTNAME=HostName
IPADDR=
DEVICE=wlan0
HWADDR=00:90:4b:71:a9:f0
BOOTPROTO=dhcp
DOMAIN=
NETMASK=
KEY=59ce04eae82fa8223afab07923
ESSID=BlazingCreations
CHANNEL=6
MODE=Auto
RATE=Auto
_______________________________________________

NOTE:
KEY= is your encryption key
Channel= is whatever channel your router is using My LinkSys is using 6 by Default
HWADDR= is your mac address of you wireless card there are two MAC's on the Dell 1450 True mobile one for 802.11A and on for 802.11G

And if you are into war driving and are in Scottsdale, AZ you can use this to get on my network.

Thanks again for your help.
