I never did get a clear answer to one of my previous questions so thought I 
would distill just that one out and make sure I understand everything.

With my current setup I have my WiFi Ranger router which only has 100Mb switch 
ports. Hooked up to this I have a 100Mb switch and hooked up to that I have the 
100Mb Airport Extreme and a gigabit ethernet capable Mac Mini.

For file transfers between the Mini and the Airport Extreme connected 802.11n 
clients; throughput is currently limited to about 10 MB/sec based on the 
ethernet side of the Airport and not the wireless side of the airport, max 
throughput for the wireless side is up in the 30MB/sec or so range.

What I'm considering doing is leaving the 100Mb router in place with a 100Mb 
connection to a gigabit switch. On the downstream side of the gigabit switch 
I'll have the Mini connected at gigabit and a new gigabit capable Airport 
Extreme.

Given my understanding of the networking issues involved; am I correct in 
assuming that internal LAN traffic (i.e., between the wireless clients and the 
gig wired Mini) will happen at a speed limited by either the 802.11n or the 
gigabit portion of the network and that only traffic destined for the router 
and hence the internet will be slowed down. I believe that the slower router 
and router/switch link are irrelevant to the gig traffic on the LAN side of the 
switch.

Alternatively; does the slower 100Mb router and router/switch connection 
artificially limit the throughput on the gigabit/802.11n LAN traffic?

If it does limit things; am I correct in assuming that the only solution would 
be to double route and have the gigabit Airport Extreme be my LAN router with a 
different subnet from the WAN side of the Airport to the inside of the 
WiFiRanger 100Mb router?

Thanks.
