help : Wifi router and ADSL modem requiring conflicting addresseson LAN

[M L]

I have a LAN with three PCs connected to Internet through a Eicon DiVA
modem.
This modem requires the PCs to have LAN addresses in the 192.168.1.2-5
range and has itself the 192.168.1.1 address.

I just bought a US robotics 5462 WIFI router for connecting a
wifi-equiped laptop both to my home LAN and to internet.

I discovered that this device only works with 192.168.2.1 address and
requires a wired LAN PC with an IP address in the 192.168.2.100-200 range.

When I give my main desktop PC an IP address at 192.168.2.100 I have
access to the router administration tool at 192.168.2.1 but i lose
access to the modem at 192.168.1.1.
If I switch back to 192.168.1.2 for the PC I can see the modem but not
the router.

Subnet mask is 255.255.255.0 for all PCs.

All PCs are under WinXP Pro sp1.

What can I do for having both the router and the modem working ?

Thanks

You can change the wireless router's IP address.

Configure the wireless router as an access point only, bypassing its
routing functions. See page 28 of the User Guide for how to:

1. Disable its built-in DHCP server.
2. Change its LAN IP address to the range 192.168.1.2-5

The User Guide is available at:

Connect one of the router's LAN ports to the DSL modem. Don't connect
anything to the router's WAN port.
