I searched for this problem so many times and couldn't find any solution. I have 2 PC's. One is laptop, other was new setup for gaming. When I'm using gaming one suddenly internet disconnects and wont reconnect until I restart the big one, while this happens I can connect to the internet via Wi-Fi on my iPhone but cannot in laptop, I'm taking same error - your pc is offline - when I restart the big one - gaming computer - I was able to connect via Wifi in laptop too.. I change my modem it didnt help me. I was using pirate version of Windows 10, I bought one and format both PC. No solution.. And this has no time. Maybe after 10 day of using PC then suddenly gone. Maybe 3 day. This is frustating.. Sorry for bad english this is not my main language guys but please help. Thanks for your moment.
