Internal IP address for D-Link 704p router

I bought a D-Link DI-704p, because i thought it could be configured just like a linux box set up as router, i.e., 1 NIC connected to my cable modem, other NICs with separated IP numbres (192.168.0.1, 192.168.1.1), in orden to separate networks using 2 switches.

My d-link router documentation says it has 1 WAN port and 4 LAN ports, but until now I've got the same address (192.168.0.1) for all LAN ports.

a) Can I configure separated IP numbers for each LAN port?

b) If I cannot do so, can I connect d-link router's 4 LAN ports to 4 ports in one switch to enhance bandwidth? My best one is a 3Com (with managment, stackable).

c) Is there any cheap product (not this d-link) than can behave like a real router?

Sorry abot the grammar, thanks a lot

The 704P is a real router.  You're suppose to connect the cable modem to the WAN port with a regular straight CAT5 cable, and all the other computers to the LAN ports.  If DHCP is enabled on the router, the router will assign each PC a unique IP address.
I have the older 704P RevA and dont' have any problems with it.
Check out the following site for more documentation on the router.

The 4 LAN ports are not seperate ethernet ports (from the router viewpoint). It is a built in ethernet hub/switch, with the 704p connected to it internally. Thus none of the four LAN ports actually have the IP address that you assign to the device it is an internal port, that is connected to these four external ports.

a.  No, you can't.

b.  No, you can't. Why would you want to ? Given that your cable might be 1.5Mbps MAX, a single ethernet port is going to be 10Mbps minimum, which is already going to be 6 times faster than your cable connection. The ethernet port is not your bottlenexk, your Internet/cable connection is.

c.  Define cheap ? Your best bet might be to use a Linux box if you want cheap as most cheap commercial boxes I have seen only have configuration for a single internal IP address.
