Here is how I understand how is configured the Network Topology when the Omega(2) is used as a WiFi Access Point. Since a picture is worth a thousand words, here's a graph I picked up on the net, and commented using an example of possible IP addresses. http://www.imagebam.com/image/d4a65a514745969 As can be seen, Internet can go back and forth through the Omega(2) to support the WiFi sub-network. If the Internet traffic requested by the WiFi sub-network is too much to bare, the Omega(2) will clearly become the bottleneck, thus limiting the number of WiFi users that can benefit from an acceptable Internet speed.
