WiFi Not Working MacBook Pro

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.

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

<< I had been using a VPN called ZenMate for about 3 years (with no issues) that changed recently to CyberGhost, which I installed about a month ago. However, when I first had the issue a few days ago, the first thing I did was uninstall that as it was the only change I had made in recent weeks. >>

You still have a whole lot of baggage from VPNs installed. you should remove ALL of them, and NEVER re-install.

For individual use, a VPN you installed yourself is Not a security improvement. It merely punishes performance and makes your life MORE difficult, without improving your security in the slightest.

At the time of this report, Zendisk was still very much involved in every aspect of your mac's Wi-Fi connection. it is being invoked by a launch daemon:

 [Loaded] com.zenmate.charon-xpc.plist (ZenGuard GmbH - installed 2018-10-28)

        Executable: /Library/PrivilegedHelperTools/com.zenmate.charon-xpc

if you see anything Zendesk there, select it and use the Remove [-] button below the list.

Editorial:

your computer is considered Vintage (i.e., getting a little old)

You have only 8GB of RAM installed, which is really not enough for MacOS 12 Monterey, but it is not upgradeable. Your currently running items have spilled over into RAM simulated on the Boot SSD drive (58 MB.)

You have a 500-ish GB SSD drive, but only about 32 GB free, which is essentially FULL. For size comparisons, MacOS requires 9 GB free just to go from OFF to up-and-running.

no backup is showing.

¿what is the date of your most recent full backup, and by what method?

<< Perhaps there are some remnants of that left behind? >>

that would not be so awfully unusual.

you can download and run this little discovery Utility, Etrecheck. Etrecheck generates a report (pre-laundered of any personally-identifiable information) which can be posted back to the forums using the (slightly complicated) included directions. Readers can help you find those remnants or any other know Bad Actors.

navigate to these directories and drag these items to Trash. They can not be removed from Trash until after they are no longer part of MacOS, which is accomplished by a Restart:

/Library/LaunchDaemons/com.zenmate.charon-xpc.plist

/Library/PrivilegedHelperTools/com.zenmate.charon-xpc

open a browser and type this all-numeric IP address:

1.1.1.1

if you get the CloudFlare** splash page, you may have a Domain-Name Server (DNS) issue, such as the specified DNS server may be offline and you may not have not specified a second one as an alternate.

**CloudFlare is not part of the solution, they just have the easiest-to-remember all numeric IP address that reliably answers with a splash page.

192.168.10.254 is a device on your local network, and even if it is your Router Address, is not good enough.

the numbers shown in my example are the ones for OpenDNS, or you could manually enter the ones for Google DNS:

8.8.8.8

8.8.4.4.

By far the easiest way to cause instability and crashing is to install ANY third-party speeder-uppers, Cleaners, Optimizers, or Virus scanners. or a VPN that you installed yourself.

The idea that a third party, with no special knowledge of the inner workings of MacOS, can somehow find a simple way to protect your computer — that is not already being done by MacOS itself — suggests that the MacOS developers are somehow "holding out on you". That is absurd.

You should remove any and all (other than Apple built-in) virus scanners, speeder uppers, optimizers, cleaners, App deleters or VPN packages you installed yourself, or anything of that ilk.

We are learning that ANY VPN features can send EVERYTHING toward the VPN, so that all but the VPN is shut off.

If the VPN is malfunctioning, even unrelated connection method stop working.

select an interface you no longer want in that list, and click the delete [-] button under the list.

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.

If your Internet service provider is having an issue, it would be out of your control...
