I am using Mac Book Air, with OS version 12.0.1.
I bought it in 2021. The internet speed is becoming slow after a use of 8 hours of office work.
Not sure why. Other devices are working fine.
Can anyone please help here?
MacBook Air 13″, macOS 12.0
Welcome to the Apple Support Communities.
Have you tried restarting your Mac and trying again? Is macOS up-to-date: Update macOS on Mac - Apple Support?
If that doesn't work, first, review Connect your Mac to the internet using Wi-Fi - Apple Support to make sure those settings are correct. Then, take a look at: If your Mac doesn't connect to the Internet over Wi-Fi - Apple Support. I'd also suggest that you read: Recommended settings for Wi-Fi routers and access points - Apple Support.
If the issue persists, add a new Wi-Fi network location and test: How to use network locations on your Mac - Apple Support.
If Wi-Fi still isn't working right, Start up your Mac in safe mode - Apple Support and test there. Also, Use Apple Diagnostics to test your Mac - Apple Support and see if any issues are flagged.
