Wifi on new MacBook Air M1 with OS Monterey constantly slows down until I restart computer

Hello:

I recent bought a new MacBookAir M1 running OS Monterey and used Migration Assistant via Time Machine to migrate everything from my old MacBook. But now I have a problem that after I start up my new MacBook Air, the internet over wifi gradually starts slowing down over the subsequent hours, to the point where I almost can't work anymore. At first I restarted the modem every time, but no results. I then tried to renew the DHCP lease, which didn't give results either. Then I discovered that if I restart my MacBook Air, then the internet over wifi returns to normal speed -- before beginning to gradually slow down again. This is very annoying.

Any suggestions of how to fix this?

Thank you

MacBook Air 13″, macOS 12.0

Hello PeterR,

Thanks for reaching out in Apple Support Communities! We understand your concern with the performance on your MacBook Air. We're happy to assist you with this.

It's not uncommon for the MacBook to run at slower speeds right after upgrading. The MacBook has to reindex the information stored on the system. To help isolate this issue, boot into safe mode to see if the same thing happens:

You misunderstand my problem. My MacBook Air is not running at slow speed. It is the wifi connection that slows until I restart the computer, which otherwise maintains its' normal speed.

It is not the settings on the router. We have three other devices connected to the same wifi and none them suffer these slowdown symptoms.
