Associating multiple bridges to one access point

One access point (Buffalo Nfiniti WZR2-G300N) is connected to an ADSL
modem through CAT5 cable, providing wireless coverage over the entire
house. What I want to do is to install wireless-to-Ethernet bridges at multiple
spots for multiple computers. For example,

[Room1] wireless signal -> bridge --(CAT5)--> computer1
[Room2] wireless signal -> bridge --(CAT5)--> Ethernet switch --(CAT5)--> computer 2/computer 3.

I bought two Belkin F5D7330 gaming adaptors (or bridges) and installed one
for each room. However, the problem was that only one Belkin bridge worked
at a time. With the bridge in room2 turned off, the bridge in room1 works
well. But once the bridge in room2 is turned on, the bridge in room2 doesn’t
give me internet connection (limited connection icon is shown at the task
bar), while the bridge in room1 still works well. On the opposite case that the
room2 bridge is turned on first, same situation happens (only the room2
bridge works).

This makes me conclude that multiple of Belkin F5D7330 cannot be connected
to one SSID at the same time.

My question is.. which Ethernet bridges (or WDS) would enable multiple of
them to be connected to one AP at the same time? Which specification can I
check to ensure that functionality? I was actually considering something like
EnGenius ECB3500 that looks more professional that the Belkin gaming adaptor.
Will multiple of this be able to connect to one AP?

Sounds like:

You are not using DHCP
All of your bridges have the same static IP

so what connects first gets the IP and everything else is locked out.

Changing the IP of one of the bridges simply solved the problem.
Thank you very much for your comment!

i use EOC-8610S EXT multiple bridges to one access point working ok but befor five days
fash problem
