Monterey 12.2.1 Internet Over WiFi is Inconsistent

Try booting to Safe Mode. That boot up takes minutes and clears caches and other things that may resolve your problem.

How to use safe mode on your Mac - Apple Support

Do you have problem when in Safe Mode

A lot of times just boot to Safe Mode followed by normal boot resolves problems.

Booting in safe mode fixes the problems for a few hours and then networking breaks again. Network connectivity stops or is intermittent with both WiFi and Ethernet. If you have NOT upgraded, stay away from 12.2.1. When is apple fixing the release. It is the worse release I have ever experienced from Apple

Similar problem here. Onboard apps work perfectly fine but internet is really flaky with 12.2.1. I may go to my news media website and it fires up just fine. Then I may go to a different site and it may work OK but when I try to go back to the first site it's like the internet connection freezes up. I then have to reboot the computer (which now takes much longer than in the past) in order to clear cache....which should be empty anyway. I've had to do that three times already today since installing 12.2.1 this morning. It's a real PITA. As you can see I'm not lacking for memory.

I'm wondering if the download/install of 12.2.1 (which took over an hour), did something to the Wifi router. I've since rebooted the router and the problem seems to have disappeared. Strange that the issue started up right after getting 12.2.1 running.

I am having the same issue. It’s driving me crazy. However, I have no issues if connecting my Mac mini to my iPhone as a hotspot. No other devices are having issues on my network. It’s only been since I updated to 12.2.1.

I'm also having the same issue on my end. I'm currently doing an upgrade to V12.3.1 of Monterey, and will report here if I have any issues going forward after that upgrade. I don't see anything listed in the "notes" for the upgrade that refer to this "connectivity" issue though.

I have confirmed that when I'm on Wifi or LAN, that I have the same "experience". I don't think it's a router issue, as other devices (including other OS device/s); work "fine" when connected on Wifi or LAN. I also tried the "safe mode" boot, and coming back to the "normal" boot and it didn't manage to resolve the issue. I actually noticed that it caused the "intermittent" internet "breakages" after coming back from the safe boot, which was strange.

I have also noticed that this doesn't really follow a "pattern" in terms of when the issues occurs i.e. last night it was giving me issues, I left the Macbook "as is" and came back today in the morning and it was "ok". So it seems random at best, and not really linked to some "third party" software on the Macbook.

Has Apple had anything official to say with respect to this, as I see this item has been open for some time?

Just an update on this... I could unfortunately not upgrade to 12.3.1 on my end, as the network kept timing out so I couldn't download the "update". What I resorted to was downgrading the Mac OS version from 12.2.1 to 12.0.1 as well (using one of my backups).

This seems to have resolved the issue, I've had no issues since doing the downgrade. So there is definitely something wrong on the previous release of Monterey.

Since I rebooted my modem/router on the 11th I've had no more problems with freezing. Websites pop up almost instantly and do not freeze. Fingers crossed.

My issue keeps getting worse. Networking only works in safe mode. I have rebooted my router. That does not help. I have two other macs that work fine. Has anyone seen how to fix this?
