Extend Wireless Signal -TimeCapsule 500GB + 2 Express 2009 - Not Work !!

Question

Hi
In my home, I use a Time Capsule first gen 500GB as Router Acess Point. Attached to it, I have 1 PC Desk(Wired), 1 Playstation3/PSP (Wireless), 1 Brigde Wifi used in my SKY Decoder, 2 Iphone (one Classic and one 3GS), 1 IPAD, 2 Macbook White 2008 and 1 AppleTV 2G.
My Home has many rooms and walls are trick, which reduces the signal. To improve the signal, I bought 2 Airport Express, but never worked properly.
When I put The express to Extends the signal, my macbook stops the TimeMachine Backup, my PS3 don´t logs on network and my And my browsing speed drops dramatically, but the sign of the signal is full.
I use the TimeCapsule as MIX WIFI (802.11N-b/g 2.4ghz), because most of the equipment working in G ( Iphones, PS3, Sky, PSP).
The configs on TC ( Criate a Wireless Network - WIFI b/g/n 2.4Ghz - Allow it to be expanded - channel 2 - WPA/WPA2 Personal - SSD WIFILNK_N)
The confis on Express 1 and 2 ( Extend a Wireles Network - Same SSID on TC - Allow wifi client - WPA/WPA2 Personal with same Key)
I don´t know what I'm doing wrong, because I tried all modes and settings in Express WDS and Deny Wifi Client Connection)and have the same problem.
I don´t try to put all in True WIFI N (2.4 or 5ghz) because the others equipments.
My last attempt is to share this problem here...

Welcome to Apple's discussion groups.
What some people do wrong with network extension is to put the extending device too far from the main station. Try moving them to a point half way between the main station and the remote client.

That menu bar icon just shows you a rough indication of the signal from the nearest access point but doesn't reflect overall throughput. If you hold down an "option" key when you pull down that menu bar icon, you'll see a value for "RSSI", which is a better indicator of the signal strength.
Use the advice in this thread on the Time Capsule to investigate the signal and noise levels that each AirPort Express sees:

I don't know what you mean by "True WiFi".
