Hi @munecito ;
How did you install network-manager in pi-topOS? Did you update Raspberry Pi OS apt sources to upgrade to bookworm or you just installed the network-manager package in bullseye?
I’m asking because on pi-topOS bullseye there’s a few packages that depend on dhcpcd (for managing the USB connections or access-point mode) so it’s probable that if you installed network-manager on bullseye, some dependencies were removed.
Some logs would be useful to determine what’s the issue. For example, the output of these commands:
systemctl status NetworkManager
systemctl status wpa_supplicant.service
systemctl status dhcpcd
cat /etc/os-release
cat /boot/pt-issue.txt
these will probably print a longer output:
journalctl -b -u NetworkManager
journalctl -b -u wpa_supplicant.service
journalctl -b -u dhcpcd
