I have a problem but cannot identify the problem? There is a packet loss problem with Ethernet and WiFi on my Vostro 3268 desktop PC. It's a 50% packet drop. On my router, the other devices are working well. But my Vostro 3268 has the problem. I buy my Dell Vostro 3638 in 2017. For nearly 1 year I am stuck on this packet loss. I cannot play any online games because off packet drop. I also call my ISP and we check but its not ISP fault. It's PC fault. Please help.
