Acer predator neo 16 network speed issue

Recently I took gbps internet connection.. My pc is easily getting 500 600 mbps using ethernet. But my laptop (Acer predator helios neo 16) is not getting that speed despite ethernet cable. It's getting the same speed I was getting using wireless connection. In the adapter settings I have checked it shows 1 gbps. Moreover I have tried enabling 1 gbps full duplex. But nothing seem to work at all. It's very frustrating for me. I have tried for quite a long time now. I would be real grateful If anyone can give me any solution for this problem. Thank you in advance
