I'm having some disconnecting problems with my TP-Link wifi adapter (Archer T4U 1200 AC) when reaching high download speeds.
So basically I have purchased one about 11 months ago. At first use I already noticed that when downloading at high speeds (+/- 8MB/s and higher) my internet would just cancel out, disconnect or what else you want to call it. Therefor I have always limited my download speed to 5 MB/sec and it would not give me problems anymore. And if it did accidentally download faster, I always had to manually fix it by disconnecting and reconnecting to my router and it would work again.
Now since I upgraded my internet to a 500 mbit download speed I am getting the same problem with it while working (browsing) with spotify on the background.
I have already concluded that this problem is not caused by my router as other devices (5 people, 3 smart tv's, 4 laptops and alot of smartphones) are not having any similar problems.
I have already tried the following:
1. upgrading the firmware
2. tried other USB ports (2.0 and 3.0)
3. use it with and without extension cable
Does this issue sound familiar to anyone or is anyone able to help me out on this? I know it's a ''cheap'' option to buy a new one but I'm more of a try to fix it person :)
Edit: I'm also in close range of my router (~2 meters)
