Theoretically this should work as you propose it. That is, configure the first 802.11n AirPort Express Base Station (AXn) as a wireless Ethernet Bridge. Apple calls this configuration a ProxySTA. Then connect a second AXn to the first by Ethernet. Configure the second AXn as a bridge. Finally connect a third AXn by wireless to the second and configure both of the for an extended network.
Are you saying I would need three AXn to create the extended network? or would it just work with 2?
AXn(Recieving)-----Ethernetcable-----AXn extending network
Will this not work?
Sorry just want to know how much I'm in for and if it will work before i go out and spend it.
Thanks for the reply
You basically have two options:
AXn#1 (configured as a ProxySTA) > AXn#2, where ">" is an Ethernet connection and AXn#2 would be configured as a bridge, OR
AXn#1 (configured as a ProxySTA) > AXn#2 >>> AXn#3, where ">" is an Ethernet connection, and ">>>" is a wireless one. The #2 & #3 AXns would be configured for an extended network.
