I have 2 wireless routers running on my windows 10 pro network. The primary is a TP-link ax50 and the secondary is an Asus RT-N66U. The TP-link, 192.168.1.xxx subnet, connects to my computers, printers and AV devices via wi-fi and ethernet connections. The Asus, 10.0.1.xxx subnet, connects via wi-fi to my IOT devices like wi-fi cameras, smart plugs and echo dots etc.
Currently, my cable modem is connected to my primary tp-link router. The secondary Asus wan port is connected to the primary via an ethernet switch. This yields an internet connection for wi-fi clients connected to the secondary router. However, it is also allowing access to primary network shares which I don’t want. I don’t want the IOT devices that are wi-fi connected to the secondary router to have primary network share access. This defeats the purpose of a 2nd router on a different subnet all together. If I connect to a lan port (instead of the WAN port) on the secondary router, I lose internet connection on it’s wi-fi clients which need internet to function.
How do I connect and configure these 2 routers so the clients on the secondary cannot access the shares on the primary network while maintaining internet access on both?.
The “easy” method would be to remove the N66U from the equation and utilize the Guest Network on the AX50 for your IoT Devices.
