Hi guys, first time using this forum, because im already with no solutions in my mind. 

I bought a TL-SG105E switch to share the internet from my modem/router VODAFONE, through cable, with my PC, PS4, and PS5. I turn on the switch plug and play, everything is fine, but the switch detects that the port 1 (connected from router) is 1000MF (detected automatically), and the port 2 conected from the switch to my PC, only runs in 100MF, if i tried setting to this port 1000MF, the switch shutdown the port, and my PC get no internet or network, even the LED from port on the switch, its turned off, showing no connection.

Of course in PC i have only 50Mb's, and my internet connection its from 1000mb. 

What can i did wrong?
