Remote connection to an ADSL line from network

I have an existing network as follows. DG834G wireless router connected to
the ADSL phone line and into this router are wired 3 PC's via Ethernet
cables. Several Laptops gain access via wireless to the DG824g router.

Due to rebuilding/extension work on the premises the ADSL phone line box
will have to be moved to a new postion that makes it very awkward to connect
to the router via cable.

My question is.---I have spare DG 834G wireless routers so is it possible to
put one of these next to the ADSL phone line box and connected to the phone
line and then using wireless connect into my existing network. If yes then
how should the two routers be configured. DCHP/DNS etc. ?

If the answer is NO how can I achieve my objective please.


thanks in advance for any help
