Wireless Connection to Sony XBR9

Question

I have just purchased a Sony XBR9 with a LAN input, an Airport Extreme 802.11n and an Airport Express 802.11n. My intent is to connect (hardwire) the Extreme in one room to my Dell & modem and the Express to the XBR9 in another room on the same floor. The manuals make no mention of this type of set-up but I believe I must set the Express to 'Bridge' mode to accomplish this.
Am I on the right track?
Have I purchased the correct equipment to achieve this?
Do I load both utilties on my PC?
My knowledge of Home Theater is excellent, my computer knowledge not so!!
Any and all guidance will be greatly appreciated.

Answer 1

On that basis (and noting the final comment of my original post!) could you please provide me with step-by-step instructions for setting up the Extreme and the Express.
To activate ProxySTA, you must set up the 802.11n AirPort Express Base Station (AXn) as a wireless client and then enable the Allow Ethernet Clients setting; both settings are located in the Wireless tab of AirPort Utility. The feature should work with any wireless network: a, b, g, or n; and 5GHz or 2.4GHz. (Note that the Express, which ships with firmware 7.3, must also be updated to firmware 7.3.1 for this feature to appear.)
Start by performing a "Factory Default" reset on the AXn.
To set up the AXn as a "Wireless Client," using the AirPort Utility, either connect to the AXn's wireless network or temporarily connect your computer directly (using an Ethernet cable) to the Ethernet port of the AXn, and then, make these settings:
o Launch the AirPort Utility.
o Select the AXn.
o If not already connected to the AXn's wireless network, go ahead and switch to it when prompted.
AirPort > Wireless
o Wireless Mode: Join a wireless network
o Network Name: <type in the network name/SSID of the wireless network that you want to join or select it from the pop-up menu>
o Wireless Security: None
OR, if you are using security on your wireless network:
o Wireless Security: <Select the appropriate level of security for the existing wireless network: 40-bit WEP|128-bit WEP | WPA Personal | WPA Enterprise>
o Password: <enter your wireless network security password>
o Verify Password: <re-enter the same security password>
o Allow Ethernet Clients (check)
o Click Update to write the new settings to the AXn.
which 'utility' do I load to the PC; the Extreme or the Express or both
Actually either as the same utility comes on each of the CDs provided with the AirPorts.
