Can't connect to router settings through Etheet

I have a D-Link router. I want to connect to the settings menu (using 192.168.1.1) in order to do things like port forwarding. I am unable to connect to this address while using Etheet (Chrome just tries to load the page forever and nothing happens), but when connecting through WiFi I can load the page. Why might this be happening? I'm using Windows 10.

Update: Tried again with Edge and IE. Same result, page just hangs and doesn't load; I don't even get the sign-in prompt.

Update 2: Used the commands ipconfig /release, ipconfig /renew and ipconfig /flushdns. Page now doesn't load at all; Chrome just says

The 192.168.1.1 page isn't working. 192.168.1.1 didn't send any data. ERR_EMPTY_RESPONSE
