The cable modem can only detect a single connected LAN side device, be that router, or computer. By trying to be clever and using your current ADSL router's LAN ports only as a switch, all that is happening is the modem sees the first device plugged into the router and then gets rather confused.

The firewall etc of the router won't work if you are just using it as a switch. The firewall relies on blocking traffic passing between WAN (internet) and LAN side ports. A switch doesn't interfere with traffic it's just a junction box.

Ebay the ADSL router and get a cable compatible one instead.
