Hi, Thank you for your post! Before going further, I would appreciate if you can clarify the following question: 1. When did this issue begin to occur? If recently, system restore can be under consideration. 2. Can you associate with any software\hardware change? 3. Where did you download the etehrnet card driver? It is suggested to go to realtek's offical website to download the corresponding driver. Please make sure the system is free of virus by performing a full system scan. At this point, it is suggested to assign a static IP address and DNS address for a test. Meanwhile, if it is convenient to you, please post the troubleshoot report as well as the Ipconfig log here. Your time and cooperation is appreciated.
