OS X / Airport / WEP / Network connection issues!

I have installed the latest firmware update.

I can connect to the network when wireless security (password)  is turned off.

From what I’ve read, WD TV Live needs/likes WPA2 and the OS X Aiport only uses WEP.

What are my options beside buying a router?

I’d rather return the device and buy an Apple TV - but I love our old WD TV. 


Does it work if you set your SSID to BROADCAST mode?
