Network manager random disconnects - no conflicts

For a past few months I've been trying to establish a wi-fi connection on macbook A1369.
Using brcmsmac driver, I've installed NetworkManager and got 2 seconds of Internet before losing it.
Since then, it connects and disconnects - nothing helps. It seems random, although disconnection always happens when I'm opening a new webpage (for example, googling something)(mb some DNS is to blame?). I have no internet for a few seconds, then everything is back to the start.

I figured out that I had a conflict of dhcpcd and Network Manager, so I deleted everything except Network Manager. Still getting the error.

Maybe networkmanager is conflicting with wpa supplicant?

Maybe I created additional problems whilst fixing the problem for this long time?

Please help.

Some standard outputs:

Re: Network manager random disconnects - no conflicts

Please edit your post to use [ code ] ... [ /code ] tags.

systemctl list-unit-files --state=enabled

won't show everything. For example, it does not show anything relevant to my networking configuration. Something like

find /etc/systemd/ -name "*.service"

might be better.

Are you sure you want ModemManager.service and systemd-resolved.service enabled?

Re: Network manager random disconnects - no conflicts

Please use code tags and post a complete journal, ideally covering multiple losses.

You got a lease, signal looks og.

It's not locally generated, so ~5 minutes later the AP kicks you.

~4s later you re-associate on first try (the log segment isn't long enough to tell whether you also got a lease.

If this isn't something the AP does (public wifi, quota) it might be down to NMs scanning habits.
Try to disable https://wiki.archlinux.org/title/Networ … domization and if that doesn't work to stop networkmanager, connect w/ wifi-menu/netctl and see whether that gets you a stable connection.
