Wireless 802.11n Help vs 802.11g Routing?

Yup, I think it will work. My setup does.

I have an Xbox 360. I got the Time Capsule the first week. And when I tried to make the Xbox find the wireless signal (whether the TC was set to n , or g/b) it wouldn't do it. I remember connecting my old Netgear g router, and the TC simply wouldn't start, showing the amber light that always signals a handshake problem.

But something must have changed, perhaps due to an Apple update, or perhaps I just set up the two routers more carefully. Here's what worked:

While the TC was running showing its green light, I connected an Ethernet cord from one of the TC's out sockets to the Netgear's sole in socket. The Netgear was then plugged in, did its startup dance, and my Xbox synced up once again with its old Netgear partner.

As for bottlenecks, I have no idea. I just know I can disconnect the 20ft ethernet cable I had running from the bedroom, under the carpet to the Xbox in the living room. Everything else is gravy.

Once connected, the Xbox streams divx and avis right to the TV screen. I assume the PS3 would so the same.

 

Most, if not all, of what you seem to be trying to do should work. See my earlier post here

Only thing to watch if "n" speed is what you are after is that you only allow "n" devices to connect to the TC wirelessly. Not all macs are "n" enabled, older macs and even the current MacMini are still on "g" as standard.

 

Sounds good to me, though personally I wouldn't buy a TC.

I have a router than splits into a switch for wired, 2 N AP and a G AP. That way all traffic between the routers has to go the router. Also it's easier to diagnose issues this way.
