Correct the DG834 is a ADSL modem/router, ADSL Firewall router, ADSL Gateway router (no wireless), a myriad of names.Chris B said:
I'd leave it on the 192.168.0.1 IP address you note in the preceding posting. But you need to get the wireless device off the same IP address (you cannot have two devices on the same LAN with the same IP address.) You can either manually set the wireless access porint (WAP) to something different in the same subnet (e.g. 192.168.0.100) or set it to be a DHCP client to the router (the DG834) and let it get an IP address from that.
You also need to disable "DHCP server" capability in the WAP and that leaves the DG834 as the DHCP server for you network; and this is all clearly described in the Connecting two SOHO broadband routers together. - JohnWill description.
