I am trying to configure SMC 7904WBRA (all-in-one) modem to act as only wifi router to connect my wifi devices into my main LAN.

I have an adsl modem as router that connects to a switch.

I just want to use this modem to connect to the switch and allows any wifi devices connected to this modem to be able to use internet.

adsl modem (auto dial-up router)*

| smc7904wbra -------> wifi devices**
8 ports switch***


Here is what I have tried.

1) main ip for adsl modem (LAN) is 192.168.2.1

2) main ip for SMC (LAN) is 192.168.2.100

3) DHCP only served by SMC. (192.168.2.101 to 192.168.2.200)


The problem is, my wifi laptop cannot surf internet because SMC modem is unable to route traffic to adsl modem. Perhaps something I need to add into the routing table?

The problem with this method is that I will then need to make the SMC the dialer. Cause for now, I am using the modem under bridge mode. I have a linux server to do the dialing for me. Hmm...maybe i have to restructure my network.

hmm..this smc doesn't have dhcp relay server.

I tried another modem Aztech DSL600EW and it can be configured easily because in the LAN of this router, can key in GATEWAY. With this gateway, the DHCP server of this router will pass the gateway info into the clients. Too bad this router have problems or else I can use it.

Anyone want to exchange router with me? SMC7904WBRA with Aztech DSL600EW.
