Description

When a total of more than 8 clients are connected and someone starts downloading (sometimes it is not even necessary to download something), then someone or even several users have completely lost the Internet before reconnecting.

I had 5 devices connected to a 2.4 network, 4 to 5 GHz network and my Internet started to disappear constantly when I started downloading on another device (ps 4) from 2.4

Tried the latest stable 19.07.3 and latest SNAPSHOTS

Research direction

Start by reproducing the reported loss of Internet with more than eight clients while downloading on the Newifi-D2, using the listed OpenWrt stable and snapshot versions. No source file or test is named; progress would require identifying the MT7621 wireless-driver cause and validating that connected users no longer lose Internet access.
