iMac cannot connect to internet after Sequoia Update

You would have had to install ESET for it to show up there. Since you didn’t install that, it is not the cause of your problem.

Also, if you are not using the Firewall (you noted it was off), none of that is affecting your Mac.

Do you have any other useless Internet security software installed?

I'm also facing this issue. Issue doesn't happen only at the start. Unfortunately, my mac would disconnect randomly, while I'm working. To recover my wifi connectivity, I'm required to restart my mac. My mac is always very close to and infront of my wifi router. While my mac is having issues connecting to wifi, my iphone connectivity remains stable and works well.

I had a horrible day and you give me the solution, my ESET showed a notificación “it isn’t compatible with sequoia OS” but I am not realize that it was the problem with not access to internet.

the solution is “system settings/Network/Filters” select ESET filter and at the bottom click in the “-“ to remove them.. and done !!!

Open you System Preferences-Airport pane and to of the plane is a ‘Location’ toggle and and custom named and don’t worry it will still auto connect like before. IMHP Apple needs to look at the Automatic because some users cheap internet routers only last about 2years!

I was connected to the wifi already, but cannot browse nor connect to internet.

Best way is this:

System Settings > Network > Wifi.

Delete the Wifi, by right-clicking it and choose 'Delete Service'.

Restart PC

Then go back to System Settings > Network

In Other Services tab, click the icon with three dots '...', Choose Add Service, and Wifi.

This will reset all your connections, try to find again your Wifi Name in: System Settings > Wi-Fi

Then just connect back if you know your wifi password. Just do this in case you did everything, ie Terminal, DNS reset, etc...

THANK YOU AND ITS WORK..

Erase all VPN setting, go to System - Network - VPN - Erase All filters

Weird. My Little Snitch has been running since I updated to Sequoia just under three weeks ago as well as the update without a hiccup. I use it as the Firewall not Apples.

I love you. 😘

(2022 M2 MacBook Air, Sequoya 15) keep losing connection and trying to connect again and again. No firewall VPN or eset is used. Changing this from fixed to rotating solved my problem. now it connects.

Same problem here. But I don’t have any ESET installed neither Little snitch.

yesterday I was able to get my WiFi connection work… but today it’s dead again.

i have tried to use terminal and check what is blocking incoming connections and it’s says com.apple.controlcenter.

have no idea how to fix it.

by the way! My telegram and WhatsApp are working on laptop and I can still chat and upload images/audio/video/make calla

I had a similar problem.

i attempted all of the above with no success.

my case was that the OS was displaying that the WiFi was connected successfully but all browsers were saying I had no internet connection.

What worked for me was turning off the “Private Wi-Fi address”.

In System Settings go to Network.

On the Wifi block got to details.

In the you will see the block for Private Wi-Fi address. Turn it off.

This is not an end all solution if you prefer this security. But will give you an insight into the problem.

In my case it’s the Access Control on my router only allowing specific Mac Addresses to connect to the network and this setting was changing the address.

I hope that helps someone.

Goto WiFi and look in details. You will see box like this. Try Fixed and Off.
