I've been chasing a strange issue since I've been working from home in early March of this year.
The basic summary is; if my work laptop (Lenovo T480) is connected to my home Wi-Fi network, any other device being used on the Wi-Fi will cause a Wi-Fi crash.
For example, if I am using my work laptop on Wi-Fi, and someone else tries to watch YouTube on a smartphone on the Wi-Fi, the Wi-Fi network will crash almost immediately. It will come back up after a few moments, but will crash quickly again if the smartphone is still trying to stream YouTube.
If my work laptop is hardwired to the router, there are no issues.
If my work laptop is not connected to the Wi-Fi (after work hours, for example), there are no issues. I can have two Xbox Ones playing Call of Duty online, with multiple smartphones connected to the network, streaming 4K video on the FireStick, etc. My Wi-Fi network seems very robust as long as my work laptop is not involved.
But, when the work laptop is on the Wi-Fi, almost any other activity on the Wi-Fi at all will cause a crash.
Sometimes even my work laptop alone on the Wi-Fi will cause a crash, if I am in a work meeting with multiple people sharing screens and/or video. I've observed this fairly regularly during the work day, where I keep all other devices (aside from mostly passive devices, such as my Ring doorbell, Ecobee thermostat, etc.) inactive on the Wi-Fi network other than my laptop. But these crashed are much more intermittent and seemingly random.
Does anyone have any suggestions on how to troubleshoot this?

I'm having the same problem with the Lenovo T480s and the Netgear R7000P router. How did you solve the problem? There is no "MU-MIMO" option in the router admin page when I followed the directions given by the moderator.
