I’ve set up a router (model STF-1200 Opal) to act as the gateway for my network as well as a DHCP server. Its range is set to 192.168.20.0/24. For internet connectivity, it connects to the WAN through a modem provided by my ISP, authenticating via PPPOE, and it’s connected through its WAN port. The internet works flawlessly.
For my local network, I have connected an 8-port unmanaged TPLink switch to the router’s LAN port. This switch caters to TVs, computers, and servers through wired connections. All devices on the local network work perfectly; they have internet access and can communicate with one another locally.
However, I’ve encountered a puzzling issue: when I attempt to access the router’s web configuration interface using its IP (192.168.20.1) from my computer, which is connected to the switch, the web interface simply doesn’t load. The browser doesn’t display an error message; it just endlessly loads. Interestingly, when I connect my computer directly to the second available LAN port on the Opal router, I can access the router’s admin web interface without a hitch.
Considering the switch is unmanaged and everything else on the local network is accessible, I’m at a loss as to what might be causing this. Any insights or suggestions would be greatly appreciated. Thank you!
