Archer C6 v2.0 - 5 Ghz WiFi Drops sometimes on heavy load.

Hey!
I have an Archer C6 v2.0 router with v.1.2.1 Build 20200110 frimware, to be able to use the 500 Mbit/s internet connection i have on LAN and WLAN.
There are 4 devices on the 5 Ghz WLAN (3 phones and my laptop) and 2 on LAN and 3 on the 2.4 Ghz WLAN.
The problem is, when i start a download from torrent, or do a speedtest, the connectivity stops, the 5 Ghz network stops the internet connection, and i cannot reach the router also, until i reconnect to the WiFi. After that, the downloads works fine without any other issues. But it happens often, when the router is not used heavily and instantly get a heavy usage.
Recently i found out that it drops sometimes without load also..
I tried to disable the NAT, Firewall, DDOS protection but nothing worked..
I am very disappointed, because i updated the frimware twice, and the problem still exists..
Any advice would be very useful!
Thank you!
I. Patrik
@Kevin_Z Wired connection is staying connected. The led is the same, but sometimes i see the status led (if i think right) go orange. I was not able to try pinging but i will try. I used QoS for a while, but it slowed down the internet speed so much, so i disabled it. I was used for 1 or 2 hours only, when i brought the router.
Have a nice day
Edit:
I was able to reproduce the problem, but now this happend: A started a download, then my internet connection broke. This is the pinging (ofc timed out) 
The internet connection still worked on phone and on another PC with UTP.
After Disconnect and Reconnect to the Wifi, the download started again, and everything worked..
As of 2020.04.13:
I downloaded a 2 Gb game from Steam store, and the Wireless completly stopped on all wireless devices, for about 20 sec.. it recovered after all by itself
