Urgent wirless networking issue

[johngalt9999]

I am trying to help my friend set up a home network, following are the specs:

*OS: winXP
*Linksys Wirless Access/ Point Router (Befw11s4)
*2 NIC cards
*2 Modems 56K
*2 PCs

***Problem:
Normally, when I set up a network with wirless router, I would simply link the cable modem to the wireless WAN port on the router with a CAT 5 network cable, then connect one of the pc with a cable or via 802.11 b PCI card. However, my friend doesn't have cable or DSL, which mean he doesn't have constant live connection to the internet (use 56K modem). So, how would I set up a home network for him via wireless router?

Thanks in advance

This the router you need.
Disable DHCP on the wireless router, and connect it to this router, using regular switch ports, NOT the WAN port. Now the wireless router is just a Wireless Access Point (WAP)
Connect an external modem to the com port on the SMC router.
There is one for sale here, cheap. All that is left is get an external USrobotics or other quality modem.
Link to router.
