I have 3 hosts (computers). The 3 hosts used to connect the router directly and the IP address of them are 192.168.0.101,192.168.0.102,192.168.0.103

Recently, I bought a switch and I linked all 3 hosts to the switch. Then, I linked switch and the LAN port of the router.

The question is if the gateway was the set to 192.168.0.1 in the router, the 3 hosts can not be detected by the router. But after the gateway changed to 192.168.50.1, the 3 hosts can be detected.

I want to keep the original IP address of my 3 hosts. How can I do to solve it? Why does not the 192.168.0.1 detect the 3 hosts?

Appreciate for any help.

below is the screenshot of the router config. enter image description here

You can change your gateway to 192.168.254.1, and still keep the same address on your hosts. As for the reason... I suspect it may be related with some auto-config feature on the switch. If it is possible, try to disable it.
