WiFi Not Working MacBook Pro

My WiFi suddenly stopped working for no apparent reason - I was in the middle of a Google search using Chrome and it came back with No Internet.

The status bar shows I am connected and when I run a wireless diagnostics it tells me “Your Wi-Fi connection appears to be working as expected”.

But it’s not. No browsers will load any pages and any applications that work over WiFi show no connection and will not open or load.

Chrome says: No Internet ERR_INTERNET_DISCONNECTED.

Firefox says: Unable to Connect

Safari does sometimes start to load and the progress bar moves to about halfway, but it takes around 5 minutes for any page to start loading.

There is some kind of connection, but with something is throttling Safari and completely blocking everything else.

It’s definitely not my WiFi signal because all other devices are connecting and working without issue and I have tried to connect in other locations with the same error.

I had made no changes or installed any programs prior to it stopping working.

I am using a MacBook Pro with macOS Monterey version 12.6.6

Any suggestions greatly appreciated.

when you enter ANY all-numeric IP address, a request for that exact page is sent to the Internet.

when you result an alphabetic request, it first generates an Internet-phone-number lookup (also known as a Domain-Nname Server (DNS)) lookup request.

if the Domain-name server you specified is not working properly, you get "can't connect" messages.

system preferences > Network > Wi-Fi > (advanced) > DNS

transcribe all the numbers there and post back to the forums.

I deleted those files, emptied the trash and did a Restart.

However, even after uninstalling everything and doing that, ZenMate and CyberGhost still show!!

How on earth do I completely get rid of these things? Maybe an uninstaller of some kind? Or do I just need to take it to a repair store where they know what they are doing?

Thank you, again!

Thanks. Yes, I got the Cloudflare splashpage on Safari.

Nothing on Chrome or Firefox.

Any suggestions what I should do? I’m not even sure what Cloudflare is?

That didn’t work unfortunately. I tried the two in your screenshot and it didn’t work, so I tried the two others and that didn’t work either.

Thanks for the suggestions anyway.

is this MacBook is running official MacOS update?

Jun 19, 2023 2:50 PM in response to SarahEFla

¿did you click the (Apply) button when done? Nothing gets updated unless/until you do.

I always close Preferences completely, and re-open to be sure I entered things correctly.

Yes, I did click apply and closed preferences. I just reopened Preferences and the 8.8.8.8 and 8.8.4.4 are still showing under DNS Servers.
