Well Bunny, I just finished getting my wireless running again after a day's worth of messing around. Let's see if I can help you out.
The latest Atheros driver for the AR5005G that I have found is here
. I have the AR5005GS connecting to a Netgear WGU-624, so we are using similar setups.
So download and install the latest Atheros driver on your laptop. I didn't even bother with the Atheros utilities, using just Win XP.
Now, using a hardwired computer, go into your WGR-614's setup page (look on the bottom of the router... using a browser enter the web address or IP and log in) and be sure that your wireless transmitter is turned on, but turn off security for now.
Set up your wireless connection using the Windows wizard, then open up Network connections, highlight the wireless Network you are trying to connect to and hit "Change advanced settings" on the left panel.
This will open up a Properties window for the wireless connection. Go to the Wireless Networks tab, check the box "Use Windows to configure my wireless settings" and add a Preferred network.
The settings should be Open and None for now, since you have no security set on the router. When you set the security up, then the settings between the laptop and the router must be the same, and of course you want to plug your key in.
Now, back on the General tab, you want to highlight the Internet (TCP/IP) Protocol and hit the Properties button.
Chances are, it is set to obtain an IP address automatically, but it may simplify things if you manually assign the IP address to the laptop. Most home networks are 192.168.0.x or 192.168.1.x depending on the routers... use your wireless router's address as a key and change the last number.
The subnet mask should be 255.255.255.0
The default gateway should be 192.168.0.1 or 192.168.1.1 (depending on network), which will either be your router or your DSL modem, depending on how your internet is set up.
I use the DNS server addresses found in the Advanced Properties of my DSL modem... this should allow seamless connection to the internet.
once you have all of that entered and saved, you should be able to connect to the router wirelessly... once you have that working, then you can work on securing the wireless connection.
Hopefully this helps!
