Hi Saney, Thank you for posting. Based on my research, I would like suggest the following:1. Please turn off your security software (such as anti-virus, firewall, etc.) to see if it works.2. Please connect the computer to the Internet directly (bypass the router) to check the issue. Please run ipconfig /all to export the network settings on the problematic computer when you connect it to the router and post the information to this thread. I will perform further research. Thanks.Nicholas Li - MSFT
