Would a wireless bridge work?

[Jimjebus]

I have theese free wireless bridge which i belive are wireless bridges i got with my Bt vision set up box which i don't use enough.

 

Now if i were to use wireless bridges to send a connection from my home hub to bridge 1 to bridge 2 in the living room to use on most products with ethernet ports e.g xbox 360 or ps3 or media centre would it work properly with a good speed or would it be slower ?

 

The bridges are made by Contrend :S

 

if this doesn't work where could i get a good cheap one from?
