1. Configure each router individually by directly connecting from a PC with static IP addresses starting from 192.168.0.1 through 192.168.0.254. Leave DHCP enabled on only the first router. 2. Connect the routers in sequence from the modem to the first router's WAN port, then from each subsequent router's LAN port to the next router's LAN port. 3. Configure each router with the same SSID, encryption, and password for the wireless network. This will allow clients to connect to one network and seamlessly roam between the routers.
