This is good choice many of us recommend as best solution.

Question: This is CentOS 6? i386 or x86_64?

You downloaded appropriate firmware and compiled all of it?

What does "iwlist" command give you?

Have you installed all other packages needed for wireless?

> I then made an entry in /etc/sysconfig/network-scripts:

Change the name to ifcfg-wlan0

> DEVICE="eth1"
Change to DEVICE="wlan0"
> #BOOTPROTO="dhcp"

> ONBOOT="yes"
> TYPE=Wireless

Add this:


Why is BOOTPROTO disabled?

Do not worry about it, most native speaking English don't bother to 
write correctly.
