Following upgrading from 20.04 to 22.04, networking doesn't work until I issue
sudo nmcli networking off && sudo nmcli networking on
This is true of both ethernet/wired and wifi and ping from the terminal. I'm running Ubuntu 22.04 on a Lenovo X230 laptop.
Perhaps relevant: when using Ubuntu 20.04 networking would work on boot but when I swapped from wired to wifi or vice versa, I needed to restart NetworkManager with the above command. Under 22.04 networking doesn't work on boot until it's restarted and I need to restart when switching.
I could hack it by adding it to login but I'm sure it'll bite me later if I don't find the root cause.
Here's the result of sudo journalctl -b 0 -u NetworkManager after boot when networking isn't working. This is using a wired connection with wifi turned off, confirmed by sw rfkill:

I can't see the reason for one working and the other not.
When it's not working ping www.google.com results in ping: www.google.com: Name or service not known
/etc/network/interfaces contains
# The loopback network interface
auto lo
iface lo inet loopback
/etc/network/interfaces.d is empty
When working output from sudo ifconfig enp0s25 is
enp0s25: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500

And when not working (previously been working hence packet count):

uname -a gives

rfkill list all gives
0: tpacpi_bluetooth_sw: Bluetooth

The yes for wifi is expected as I'm currently testing with wired. If I switch wifi back on, rfkill behaves as expected and network issue remains.
I'm using kernel 5.15.0-46 so it's not this issue
Package backport-iwlwifi-dkms isn't installed so its not this issue
Any help much appreciated
