After the update Catalina 10.15.7 have problems with the Internet connection

Hey Ken. I get your point, these devices aren’t exactly cheap. However the technology and our wireless environments are constantly changing and evolving. I’ve seen many bugs over the years, not just with Apple, but with many tech companies.

Of all the tech companies I’ve used and worked with, Apple is by far the most responsive, not just by responding to feedback, but also by being available to talk to, work with you, and actually willing to individually put in the time to try to help your, and other’s issues.

In either case, I don’t think a public complaint would do anything to help resolve the problem, but would rather suggest contacting them directly to take a look at it, investigate it, and figure it out, as they are more willing to do so, and more readily available than any other tech company I know.

Hope it works out on your end though, I know how, when you need a connection, especially now-a-days, you need it to work. But as I’m sure you know, technology is not perfect, and there’s no set science to make it work for everyone all the time, and never will be.

I’m sure if you contact them directly, they’d be happy to help out, if not to fix it right off the bat, then at least learn more as to the cause.

It's clearly something that has been around for a while:

None of the solutions suggested in that link by mike1london seem to work.

Spent 2 days chatting with "Apple Support". Forget it, they'll never fix it. They don't care.

A summary of the "support":

• Them: does it occur in recovery mode?
• Me: yes.
• Them: then it's a hardware issue.
• Me: no, because the same macOS Catalina base system is being used in recovery mode.
• Them: uh... It's still certainly a hardware issue.
• Me: no, computer wifi was working fine until migrated to a fresh install of macOS Catalina. All my other home devices connect fine.
• Them: well, your computer is obsolete (Macbook Pro mid-2012). We don't support it. I can arrange an Apple Repair if you want because I believe it's a hardware issue.
• Me: it's definitely not a hardware issue. Tons of people are having this issue. My Macbook Pro wifi was working fine until I migrated to a fresh install of macOS Catalina. I think Apple needs to look into it.
• Them: Disconnected...

They've offered to help me migrated back to High Sierra. I said I could do it myself.

Disheartening...

The problem is that with distance (extremely short for a wireless internet connexion), the wifi connexion is unstable and drops.

Like being in another room, it drops so much that eventually you are not connected to internet anymore.

Never had this issue. Used to be able to go in my garden...

So, I went through all the pages of this thread, and here is what I can say.

I do not use any of the security softwares mentioned in the 10 pages of this thread.

I do not use MS Teams.

I do not have Mail sync in iCloud.

I only have an internet provider router, nothing else. Nothing complicated.

I do not have any fancy DNS settings. It's basically empty that section.

I do not have any proxy activated.

I have obviously the Apple firewall activated (God knows why they don't activate it by default... )

I am on WPA2, no WPA3.

Renewing DHCP has no effect.

Unplugging and replugging the router has no effect. Don't know why it would have an effect for this particular device in the house anyway while all the others are working fine, as it used to as well when on High Sierra.

Creating a network location as suggested by Gw241 (instead of automatic config) doesn't work, or maybe it did for a bit (or maybe it was psychological...).

Recovery mode or failsafe modes have the problem too.

The Wifi chip/card/interface is detected no problem.

Sometimes, it claims to be fully connected (all wifi arcs are black in the wifi logo), but internet is slow. Clicking on the wifi logo refreshes it and shows that the signal has actually dropped again. That's why some are reporting slow internet connection as well. But it is in fact a drop of wifi signal.

I can even see it right after boot, at the login screen: Wifi connected with all 4 arcs, and then by the time the login is completed (2-3 secs), boom, wifi drop. Turn off wifi, turn it back on. Full signal, and then within 2-3 seconds, boom, no signal.

To use Wifi, I have to be within 2 legs distance from the router... and it still sometimes drops anyway.

Ridiculous.

I have the same problem and on three different macs, two macbook pros (2020) and one imac (2015). While the network interface states that it has an internet connection, there is no response from the router when prompted in the command line.

Does it show a green dot in System Preferences->Network?

Click Advanced, then click DNS. What does it say?

I have the same problem and I noticed it about a week after the update.

I also have tested with and without the Microsoft Teams app, and it remain stable without teams notifications.

Keep testing!

This is a long thread, and it is best if you tell us exactly what you tried:

• create a new location?
• add a new DNS server, such as 8.8.8.8?
• other things?

Clearly various wifi problems with Catalina.

In this thread, they report a loss of the wifi interface itself, visible in syst reports

I too have the same problem. I updated my Mac Book Pro (2019) to 10.15.7 over the weekend and when I started using it for work on the Monday the internet access keeps hanging. Wifi signal is strong and does not drop. The only way to get an internet connection again is to turn off the wifi on my MacBook and then enable it again. But this is only a temporary fix, it is unpredictable how long the internet access works, it can be 10 mins to 1 hour before I have to turn the wifi on and off again.

I don't realise the internet connection has dropped until one of the following apps stops working - Outlook, MS Teams, Safari, OneDrive, Zoom and Bluejeans.

I have no issues with other laptops, iPhones or SmartTvs in the house.

Having seen the above post i have decided to hold off on updating my iPhone 11 to 14.0.1.

Apple - Please fix this issue asap as I use my laptop everyday for work.

Hi Luis,

I am grateful that you monitor this forum and are quick in replying to people's posts.

But please answer me, Are 3rd party solutions (be they security programs or productivity or entertainment) not welcome on MacOS?

Tomorrow, if VPN software (which is for security) causes network drops after an update, will forum moderators call them the problem too?

Should users not report bugs in the future and assume that only Apple SW works on Apple HW?

Third party software is of course welcome in macOS.

I use a lot of third party applications too, and I’d be pretty upset if that were taken away!

But the problem is that many these so called “antivirus” and other “security” applications are either completely useless or downright harmful.

An “antivirus” is not just unnecessary, it degrades performance, conflicts with the very serious built-in security features of the OS, and gives unsuspecting users a false sense of security. There exist exactly zero viruses capable of infecting a mac. That is not to say there is no malware: there is! But it is the sort of malware that requires active user participation to get installed. By using phishing and other engineering techniques it fools the user to allow the installation of harmful software. An antivirus provides no protection against that.

Other common sources of malware is aggregation sites that offer all sorts of “free” downloads, and torrents. Again, having an antivirus does not protect the user from his own misguided dodgy website visits and downloads from untrusted sources. Common sense, on the other hand, does.

VPN software is perfectly legitimate, of course, but it needs to be properly implemented and - quite importantly- it needs to be kept up to date. The same goes for any software, of course.

And last but not least are programs that falsely claim to clean, optimize or speed up your mac. Cleanmymac is notorious for corrupting mac systems left and right. (Then of course people blame Apple)

But of course there are many other scams out there.
