Check that NM didn't somehow acquire a spurious route. Edit Connections
-> Your connection, little gear wheel in the lower left. IPv4 Settings
-> Routes.
Are you sure you aren't getting that spurious route from the DHCP
server? To check on that, add a short script to
/etc/NetworkManager/dispatcher.d, called, say, 50environment. It should
look something like
--------------------------------------------------
#!/bin/bash
LOG=/var/log/NetworkManager
{
echo "Environment is:"
printenv
route -n
} >> "${LOG}" 2>&1
--------------------------------------------------
Somewhere in that log file you should find a variable that specifies
extra routes, if any.
You can also check to be sure you are getting the correct
address. That should be in $IP4_ADDRESS. Mine looks like:
IP4_ADDRESS_0=192.168.100.44/24 192.168.100.31
I think the second address is either the DHCP server, or the DNS server.
The variables NM uses are detailed in man 8 networkmanager.
