[X4U] Can I use a wireless router like a wireless repeater?

[Crandon David]

Hello all,

I'm making my first foray into the wireless router world.

I have two LInksys WRTU54G-TM routers (the TM stands for T-Mobile).

I bought them to use with a wireless security camera as well as T- 
Mobiles @Home phone (VOIP) service.

One is wired to my computer of course, but I'd like to know if I can  
use the second one as sort of a "repeater" to extend the range, but  
do it wireless?

Is this possible?

David
