Just purchased iMac with Snow Leopard OS. Apple tech spt states WEP broadcasts incompatible with OS. Need to update router to WPA or WPA-2. How do I do this with DI-614+

Basically ypu will need to change the wireless settings of the router.
To change the wireless settings you will need to access the router set up page.
Is there any computer connected to the router? If not then you will need to connect one computer to the router with the cable. Open the set up page of the router and change the wireless settings of the router. When you change the wireless security settings, change the wireless network name also ( SSID ). Once you change the SSID and the security on the router, you will need to connect to the wireless network on all the wireless devices with the new network name and security
