I have a modem-cum-router with DHCP enabled as my primary router. Primary router is 192.168.0.1 and DHCP lease pool starts at 192.168.0.20. The DOCSIS internet cable is connected to it. I have a network switch connected to this router. A secondary router is connected to this switch via Ethernet. (Cable connected to LAN on router.) The secondary router has DHCP disabled and has IP address as 192.168.0.2.
The secondary router also has 3 more LAN ports. These wired LAN ports have no issues connecting to the network. But, for the wireless connections on this router, I am facing some issues. If I connect a device to the secondary router wirelessly, then no issues. But after that if I connect the same device to the primary router wirelessly, then the device only connects to the primary router and always gets stuck at obtaining IP address while connecting to the secondary router. If I forget both wireless connections on the device and restart the secondary router, then only can I connect with the secondary router again. But if I connect to the primary router, I get stuck in the same loop. Also, if I ever connect to the primary router first, then I cannot connect to the secondary router. I have been trying to get this working since 3 days! I am on the verge of losing my mind and laughing hysterically until I die. Please help!!
