No Network When Connecting Deco X20 With TL-SG105 Switch
So I have a Tp-Link Deco X20 mesh WiFi router. Since it only has two Ethernet ports, so I bought a switch to support more wired connections. The switch I bought was Tp-Link TL-SG105, which is an unmanaged switch.
After the setup, now I have this connection order:
Modem -> Router -> Switch -> PC1, PC2, PC3...
But the problem I have is, when connecting to the switch, my PC can't obtain IP address. It seems like the DHCP on the router is not working at all. I'm getting "Unidentified network" with a 169.*.*.* IP address
.
My other iMac also cannot obtain IP when connecting to the switch.
When connecting the PC directly to the router, it works fine.
What could be the most possible cause of it? Is the switch malfunctioning? Or the Deco x20 needs some extra configuration in order to support an unmanaged switch?
Please help!
