how do you have the setup done ?
1- 2 seperate networks one for main router one for the assus and 2 NICs on the streaming machine and then you bridge the two networks from the OS.
2- 1 network, but Asus acts as a wireless Repeater (getting a main network IP wirlessly then broadcasting on the LAN ports) ?
I use #2 - one network. Asus is a client bridge (Note, not repeater), and primary router is DHCP server.
The speed is awesome in this mode, better than seeking wireless-N USB adapter, in my opinion. Of course, if you stream 1080p video, you could upgrade routers to N/Gigabit. Still saves money in the end.
