I am using Windows 10, Ryzen 5 with a TP Link 2.4G wifi receiver.

I first noticed the wifi problem when I was playing valorant. It lags because the packets (icon from the game) suddenly gets high on the graph.

Sometimes, I also get disconnected in a zoom meeting.

All our devices at home including laptops, tabs, and smartphones work fine with our internet connection. Only my Windows PC have the problem.

When I try speed testing, it would detect 72mbps then will suddenly drop to 40mbps. Like it is lagging.

I have tried changing the wifi receiver, and I bought a new one so I don't think that's the problem. I also reinstalled the 802.11n driver.

Any idea what could be the problem? Please help me.
