Poor WLAN throughput between clients

[JB_Walton]

Hi,

I have a the next setup:

WL 500g router
PC (wireless client) + XBox wireless client

Transferring big files between router and either client : 5 mbps
This is good for me.

Transferring between PC and xbox (either way): 500 kbps.
How can i boost that throughput between two wlan clients?

I want to view a dvd on my pc (harddisk) with the xbox.

Any tips?

JB
