Use Router as access point for Android

Here's the deal.  I have an Android Razr Maxx with unlimited data access (grandfathered in).  I use the "hot spot" feature to broadcast the internet 4g signal from my droid to my wireless computers.  Our house is very large and when we get too far away from the droid we can't connect.  I have a Linksys wrt54g router with dd-wrt on it.  I have read for many hours online as well as videos but to no avail.  I want to make the linksys router a repeater of the android signal so that the further we are from the android we can still get the internet reception.

Any ideas?
