ADSL USB Modem through Wireless Router: is it possible?

Hello everybody:

I am pretty new to the wireless world and I am having some problems
to find information.

I have an ADSL USB modem (Sagem fast 800) and I'm wondering if it is
possible to attach this modem to a wireless router (I was looking at
SMC 7004VWBR, for example) so I can have the modem + router wifi in a
room and the computer in another different room.

It is important and it would be great to not use any wire in my home
.

Thanks in advance.

Oscar.
