CPU overloaded when wi-fi is enabled

kr flag

I just received a brand new laptop today (the Neptune 15" v2 from Juno Computers) that comes with Ubuntu 20.04 preinstalled. I've been having a strange issue with the wi-fi since about an hour after I turned it on for the first time.

Sometimes, a few seconds after I enable the wi-fi, while it's still trying to connect to my router, the machine starts running agonizingly slowly --- the display updates about once per second. I've run top while it's in this state, and there's a kworker taking up a lot of the CPU when it's in this state. Sometimes it will eventually succeed in connecting to the wi-fi and sometimes it will fail, but either way it will go back and forth between running smoothly and slowing down a lot, and the wi-fi will cut out a lot.

My phone is connected to the same wi-fi network with no problems, and everything is consistently smooth when connecting through Ethernet. The wi-fi device is "Wi-Fi 6 AX200" from Intel.

Does anyone know what this might be? I'm happy to provide any additional information that might help.

Hi... If your issue is with overloading CPU you can use gnome extensions like Cpu freq which allows you to control your cpu speed

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.
