Why does my series s says Ethernet cable is plugged in when it's not?

My Xbox series s won't connect to the Internet, I usually run it on a network/Ethernet cable. Then the other day it looses Internet connection while playing starfield. I reset the console by unplugging it for 30 min. Didn't fix it. Unplugged the Ethernet and was just gonna use the wifi, but it acts like a the Ethernet is still plugged into it when it's not. Wont let me go offline or use wifi.
