macOS Sequoia network issues

Since a unexpected update to Sequoia from Sonoma, i've started to have lots of problems with network connections, VPN, WiFi connections and also wired connections..

I'm working mostly from home and there are no issues with my internet connection, every other device that is not a Mac works flawlessly..

I work using VPN and it disconnects very more than often/day. The WiFi connection never drops from Mac OS but during the "disconnection time" i am not able to browse anything , means a possible internal DNS problem?? , but i am able to ping 8.8.8.8 or whatever . i'm working leaving a terminal window with a active ping to 8.8.8.8 and when my VPN gets disconnected the ping stops too and i get the shell prompt..

I've read all the posts, i have no active firewall, i've a fixed ip for wifi, the connection disconnects also with a WIRED cable (tried with different LAN adapters) and wifi down.

The only good point, looking at all the messages on this thread , is that i am not alone.. but someone (Apple?) should fix this behavior . Before with Sonoma everything worked well..

Thanks.

OK, I've had enough of the drop outs. As a I posted, the only thing that seems to work, but not always now, is toggling WiFi off and on. I was doing something important on my Mac today and the internet dropped out again. After spending 10 minutes trying to get the internet working again, I had to start my work over. This is a very poor showing from Apple - is there a fix rumoured to be coming soon?

After pressing post on the above I closed the computer used to log on the server vis VPN and went to bed. Next day (27th) the problem has returned. Server Terminal app was left open on the server and when logging I found these strange lines on the terminal screen that appears to have been created by about 1 minute (26th) after I made the above post and close VPN connection.

I will check with corporate IT tomorrow to see if Ntiva has messed with the server.

Also having intermittent network issues since updated MacOS to Sequoia.

Even after downgrading back to Sonomo, some Macs lose their network connection randomly, either in the middle of the day or in the morning after a reboot.

Reapplying all network settings restores network connection for a while. So, we've created a script that does so that users can fix the issue by running it, but any suggestions regarding is welcome.

If the OS was upgraded in place, its worth trying re-installing the third party protection software. All of my connection loss issues vanished after uninstalling my Sophos Endpoint Protection client. I suspect that the in-place upgrade of the OS with the changes its making to the networking stack isn't playing nicely with already-installed third party software.

I have an update :

It looks that my "Problem" it's Microsoft Defender ( or something related to it).

As a recap : i already have Mac Os Sequoia 15.0.1 that does NOT solve the problem, i am using VPN (Fortinet /Cisco) and leaving everything active on the Network Extensions made the Mac Os Network connection disconnect.(General/Login items & Extensions/Network Extensions)

Disabling Microsoft Defender Extension made my pc connected again and stable without any disconnection. I've tried it for many hours and i can say that (for me) this is the main problem.

Our support is working on it if i have update i will share with you all .

This problem is still with my M1 MacMini (LAN cable to modem). There doesn't seem to be a pattern except that at start-up the internet will work, then stop a little time after that (but not always). Then, I switch on WiFi (it works, most times) and then switch off WiFi and go back to LAN only. Sometimes this doesn't work, and I need to restart and that works...half the time. It just crashed again while I was typing this (fortunately, I copied what I had typed and pasted it in) - I had to switch on WiFi again to get internet access. Had. Enough.

Turns out that this server is the only computer in the building that does not have Ntiva installed. So that was not an issue.

However, server now stays on for random length of time. Rebooted yesterday morning and it stayed on until 4 AM today. Had to reboot twice today, getting about 2 hours on a boot.

I used set it up to reboot every day of the week at midnightusing:

sudo pmset repeat restart MTWRFSU 00:00:00

Now looking for a way I can have our remote webpage monitoring service send a message that can be used to trigger a reboot.

I installed the 15.1 update last night and all seemed well. The start-up this morning was the fastest I've ever seen on a Mac. And, it connected to the internet via LAN! THEN, it disconnected and I had to toggle-on WiFI to get the internet working again, wait for a moment and then toggle WiFi off. Sigh.

I applied 15.1 as well. Initially seemed okay, but now my secondary copper interface is flaky; Finder open on a share across it will randomly drop some or all listed files, and I have to close the tab and reopen from network locations > my server > my share > mydir

I didn't have problems with my wi-fi randomly disconnecting until I updated 15.01 to 15.1. My wi-fi connection drops at least 6 times a day; my primary network will not auto-connect, I have to select it. I updated my wife's MacBook Air from macOS 14 Sonoma to macOS 15.1 Sequoia and boy is she really mad at me for updating her computer since she is having the same wi-fi issue. There is absolutely no problem with my network as I use YouTube TV and it is on the same network as our laptops.

Same issue. Upgraded from Sonoma to 15.1.

Mac Studio

M1 Ultra

10Gb to SNS Server, direct connection.

Video editing, Adobe Premiere

Was working fine before upgrade.

Since on 15.1 it will disconnect the network drives when I do an export from Adobe Premiere, sometimes right away sometimes after it gets halfway through the export. The drives just disconnect. Tried all the usual fixes, even a Thunderbolt 10Gb adapter. All "fixes" gave the same result, no fix. For me not even a fix for a little while, all setting changes/adjustments gave no change.

The curious point is that when I'm just working in Premiere and not exporting it's fine, no disconnection. It's almost like the sustained high throughput causes it to crash.

Luckily I had the media I needed on another drive or I would be dead in the water with no way to export this project.

More information. Just clicking on files and playing videos from the network drive is fine but for example UnZipping a file causes it to disconnect. Copying files from the network drive to an external hard drive is fine, no disconnection.

However we are dead in the water! As I cannot export any video projects, all our main video media is on the network drive and would take hours/days to move to another non-network drive.

197GB out of 2TB. I'm using iCloud which manages the Desktop and Documents.

Seems to only effect my Mac Studio. My MacMini (M1, 16GB, 15.1) is fine (so far) in connecting to the same server and I can do exports from Premiere from that server with no problem (so far).

I wish 15.1 did fix the problem. It doesn't for me. Finder open to a directory on my 10GE copper link still randomly goes off in the weeds.

The intermittent black-window and magenta-screen issues on my Studio also remain from Sonoma.
