Problems with the Internet, second disconnects. What to monitor?

Question

Computer networks

Hello. There is a home network of this kind:

Wi-Fi routers themselves on a free channel, almost in the line of sight (behind a small piece of wood). The problem is that with a constant load such as an online game + WebRTC (discord), there is an Internet disconnect for a second, which unpleasantly interferes.
How can you monitor and understand what the problem is?

Answer 1

You can monitor PingPlotter if under Windows: www.pingplotter.com
But the online game with Wi-Fi does not fit. Moreover, the routers are behind a small piece of wood. Throw the wire already, be normal people, there is no need to suffer.

Answer 2

pingploter to the game servers, and test it for at least 30-50 minutes, where you can see exactly where the cliffs are. Another option is to update the firmware on routers, I had a similar problem on an asus router, as I updated the firmware to the latest one, everything began to work perfectly.
