Rfkill randomly disables wifi

Rfkill disables wifi. It happens often when I run some resource-heavy app like chrome, or randomly (happens about 1 time per 30 mins ~) when computer is not under heavy load.

Logs from network manager:

NetworkManager[934]: [1632350333.5819] manager: rfkill: Wi-Fi hardware radio set disabled

After turning it off and on, rfkill enables it:

NetworkManager[934]: [1632350335.5534] manager: rfkill: Wi-Fi hardware radio set enabled

It's a little annoying to restart it every time and refresh all. Does anyone know what might be the cause?

Probably an incorrect power management setting. Please edit the question and add your specific Wi-Fi hardware.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
