After I upgraded Windows 10 (from Windows 7), I began to experience, problems with my WiFi connection. From time to time the WiFi icon (bottom right corner) next to the clock will display small yellow ! sign saying "No Internet Access". Also games (WoW,LoL) are causing this thing to occur. My internet is not the problem, my laptop was running perfectly on Win7. I have couple of other devices here at home running perfectly - phones, smart TVs and two other machines running Windows XP and Windows 7. They have good stable connection while on this laptop shows "No Internet Access". The laptop is literally next to the router, so there is zero signal distortion. I have tried some things which I found on the web but none of them helped. The laptop is Lenovo G580 Please help me, because this is getting ridiculously annoying.
I wrote a ticket to Riot Games and they gave me a guide to follow which was supposed to help me (guess if it did ) That's it: https://support.riotgames.com/hc/en-us/articles/201752664#section-windows.
PS: Last year I installed Windows 8.1 on the laptop and I had similar problems, I couldn't fix it so I installed Windows 7 back.
PS2: This "No Internet Access" problem is not constant. Its from time to time and whenever I launch a game. There are 3 things that help fix the problem temporary:
1. Turn the WiFi off and then on
2. Disconnect and then connect to the network
3. Restart the router
