So using the following simple test method and test program, I'm not seeing anything near 900mbps on the WAN to LAN test.

Seems like the HW NAT accelleration or Cut-Through that should be working on this router, isn't. This test is using the WAN port. I don't have any support for the SPF+ port.

This would not be acceptable for users on a 1Gb ISP plan with this expensive top of the line NG gaming router. :smileyfrustrated:
