Check to make sure you don't have any firewalls enabled that shouldn't be. Also, when you say you assigned a static IP, where did you assign it?

Something similar happened to me when I changed out a router. The ATA had a static IP and the router was DHCP. I reserved the same IP address in the router that was statically assigned on the ATA but that did not work. Assign the ATA to be DHCP as well. Maybe that is not your issue, but worth a look.
