I've finally (after a full week) gotten my wireless adapter in in the Network Configuration box. It shows as active (only after I set a static IP) however I can't get on the net.
I have tried to ping the Rounter but it doesn't work. It says "Host unreachable".
The only thing that I can think is the problem is the fact that I have my router is setup with WEP and a passphrase. Something I read said that passphases aren't supported by CentOS.
Can someone help me get this think working please?

Verify you can get a working connection first by turning off WEP on the router.
Insure that your router and wireless device are using the same 64 or 128-bit encryption, Linux defaults to 128-bit encryption.
Verify that a /etc/sysconfig/network-scripts/key- file exists and exactly matches the hex key of the wireless router or the key is modified correctly to for the passphrase: KEY=s:mypassphrasehere

Re: Wireless Network Adapter Active But No Internet
How do I change the level of encryption in CentOS? (ie. 64 or 128)

Review: man iwconfig
Please check first by:
iwlist scan
iwlist key
I forgot to answer you concern, yes Linux supports WEP encryption and passphrases.

Re: Wireless Network Adapter Active But No Internet
I reviewed: man iwconfig
I can set the key s: using this command however, I couldn't find anything that said how to change from 128 to 40bit. Currently, my router is set to 40bit so I think that is the problem.
Is there a command to change to 40bit?

Re: Wireless Network Adapter Active But No Internet
Thanks for your help!!!
I figured out that my router is set to Channel 4 and my setup in CentOS was set to channel 11. After changing my setup to be the same as the router I got it working.
Question: During boot when it tries to configure eth1 it says "SET failed on device eth1: Invalid argument." But it still connects and gets me an IP address.
Does anyone know why this is?

Known bug with the wireless-tools nothing to worry about. One can edit the /etc/sysconfig/network-scripts file if this bothers you, sample below;
TYPE=Wireless
DEVICE=eth1
HWADDR=
BOOTPROTO=
IPADDR=XXX.XXX.XXX.XX
NETMASK=255.255.255.0
GATEWAY=
DOMAIN=
ONBOOT=yes
ONHOTPLUG=yes
USERCTL=yes
IPV6INIT=no
PEERDNS=no
ESSID=
CHANNEL=4
MODE=
RATE=
Also you can check the /etc/sysconfig/network-scripts/keys-eth1 file for your passphrase;
KEY=s:my_pass_phrase_here
