    Wireless-AC 8265 killing my network. Firewall blocking errors. internet speed 10x lower.


      I've had this problem for more then a week now. And at first I thought it was my router problem etc.
      But here I will explain what happens.



      The main issues is when playing online games, sometimes just particular ones.
      And the issues persist for an hour even after I exited the game.
      I still got a quarter (3-6mbit/s) sometimes around half (6-8mbit) of my 16mbit/s connection but could watch youtube in 1080p and do everything else except when I start gaming.





      Here is one event:
      1. when running that online game (rust) , I could play for 10 minutes but then people start teleporting and i get *timed out* errors.
      meanwhile I can't open ANY website, and if I was lucky to open speedtest.net, and if I was lucky to actually DO an speedtest. it showed me 0.50 download speed. ping mostly double or triple from the normal 56 ping.
      And if the speedtest website didn't start doing the speedtest. it showed me an error about firewall blocking connection. It even showed me a few times a totally different speedserver server somewhere in Poland (instead of germany, at the border close to the netherlands which is the opposite side of poland) and there was a red triangle thing showing me that my ports are blocked or whatever.


      2: Speedtests. this speedtests are AFTER I exit the online game client. and can persist up to a few hours

      3: Speedtests MANY hours after I stop playing the game.
      Speedtests average the same everyday whenever I try running the online game.

      5. Playing a LAN game (Factorio)
      Now this issue is the weirdest one and always happens. whereas in the online game you can play for the first 5-15 minutes before the issues start.
      In Factorio, me and another person are both connected to the same router and we use that router access point to connect both of our laptops to play the game locally without creating a server or whatever.
      Once the other person joins, most of the things work okay, but as soon as you open a youtube video or something, the exact same problem appear, except sometimes you DO open youtube but videos not buffering at all, just a black screen not even a millisecond.


      6. Sometimes it nothing works at all and when I try to open a website I get some kind of DNS errors.
      And sometims when the wifi adapter shows a yellow sign that it has no connection to the internet and when I try to resolve the problem.
      It says that the Device cannot communicate with the main DNS server.




      I hope all this facts help you to help me if anyone will actually try helping me.

      Please HELP ME!!
      I start regretting choosing this model of the laptop because the wifi adapter was one of the reason I choose it, I had a choice between the AC WLANKiller™ and 8265, but AC WLANKiller™ had bad reviews about having troubles connecting to different networks.
