MB only shows 100 mbps should I get a new NIC

So I just upgraded ethernet to 1000Mbps and I wanted to check my MB's capability.

So I went into Network picked my card and pressed Status - it showed 100Mbps

My mb is a MB1151 Asus B250M-A Prime ( [https://www.asus.com/dk/Motherboards/PRIME-B250M-A/specifications/](https://www.asus.com/dk/Motherboards/PRIME-B250M-A/specifications/) ) it says Gigabit controller, but ethernet status only show 100Mbps.

So do I need to upgrade to a gigabit NIC?
