Macbook Pro 2019 13-inch issues with MacOS Monterey 12.0.1

Hi,


I "upgraded" my MacBook Pro (13-inch, 2019, Two Thunderbolt 3 ports) to MacOS Monterey 12.0.1. Just after the "upgrade" my wifi keeps being disconnected. I got an ethernet usb adapter (1Gbps), same thing, it disconnects randomly. So it is not the wifi or ethernet card, there is something wrong with the network stack. I am thinking of going back to BigSur. I already tried the SMC and NVRAM tricks, same thing. Anyone with the same issue? The computer worked flawlessly with BigSur.

Hello IvanCL,


Thank you for using Apple Support Communities. Based on your post, your MacBook Pro keeps dropping Wi-Fi connection and ethernet. We'll do our best to assist.


Have you had a chance to test this in safe mode: How to use safe mode on your Mac

Testing safe mode will tell us if there may be a third-party extension causing the behavior.

Use sections, 'If the issue continues in safe mode' and 'If the issue doesn't continue in safe mode', depending on the results there.


Keep in mind, if you're using a VPN or security software, we'd recommend to disable them and restart the device; as these may be blocking the connection.


What happens if you connect using another user on your Mac to test this out: Set up users, guests, and groups on Mac

Doing this will help to isolate between all users on the Mac or just happening within your user account.


Hoping to hear back, take care.

Hi destiny241,


Thank you for your help. I found the following active under my Network configuration:

"Cisco AnyConnect Socket Filter"


I disabled it and the issue went away. I have not tested my AnyConnect VPN after this but I rarely use it. So it is good for me now!


Cheers!
