Hello, I am using acer predator helios 300 ph315-51.
Essentially my internet gives out every time i do something that is heavy on the laptop internet, namely gaming. I use wifi so i don't have ethernet.
When i first got the laptop, everything was fine. I have this laptop for nearly 6 months now. I don't know how this started happening. Every time i try to play something online, like siege, league, csgo, after about five minutes (sometimes thirty) the network goes on either no internet connection (the yellow caution sign) or just stops working, yet the icon shows there is internet as normal. This fixes right after i disconnect and reconnect to the wifi.
My network driver is Intel Wireless-AC 9560 160mhz, updated from the intel website to the latest version (which is 220.127.116.11). The driver date shows 11/11/2018. I've disabled the option for "allow this device to turn off to save power" but it has no effect. Only 1 other laptop in my house suffers from this, but it is very rare for them. All the other devices work just fine. Speedtests show that i have 75+ mbps download stable, but this is false for my laptop.
Generally, my gpu and cpu temps go up to 90 degrees C and sometimes my cpu goes up to 100 degrees C. I always have max fans on and sometimes GPU overclocked to "faster". I thought that this is the reason, but i had 3 tabs on at once in firefox, my cpu is cool, and then my network stops working again, just randomly. I've had these temps since the first time i played on the laptop, so I doubt that this is the main issue. This issue is so frequent that i have to alt-tab, reconnect, alt-tab back in to the game every few minutes, or in other games i just get kicked out of the game for no internet connection.
