Hello,

I am using Debian 11, and no matter what I do, I repeated on each
reboot, I will boot into a system with no gateway set (or rather, the
"default route is 0.0.0.0," which naturally gives this device no
internet connectivity.

I am using the NetworkManager, and have a static IP set.

If I turn off the network, and restart it, then it will set the Gateway properly.

All other settings persist through reboot, except for the gateway.

I have not found an error messages, and as mentioned, if it restart the networking, it works. Just on reboot, it does not set the gateway properly.

thanks in advance.

Are you talking about connecting to an internal network or are you
talking about connecting to your ISP's network?
If connecting to an internal network, do you have control over this
network?

I am using the NetworkManager, and have a static IP set.

So you configured a static ip (4?) and did you also configure the netmask
and gateway statically?
Or are you expecting your host network (local or your ISP?) to send the appropiate gateway to your client?

If I turn off the network, and restart it, then it will set the
Gateway properly.

All other settings persist through reboot, except for the gateway.

I have not found an error messages, and as mentioned, if it restart

If you are talking about connecting your client to your ISP, did it ever
work as you expected? Did it stop working? After which changes did you
make on your side?
Your ISP or your local network might grant you a fixed IP address but
they still might supply the address and the gateway via DHCP. In that
case their DHCP database contains an association between the MAC address
of your client hardware and the fixed IP which they send to you together
with netmask and gateway.

Did your MAC address change by any chance? E.g. change of hardware?

thanks in advance.

1. I am talking about basic network connection. I have an ip, so I can
ping local machines, including the gateway router itself.

'ip a' shows the following

I have commented out all the enps27s0 so that the NetworkManager can
handle it. When, I uncomment them
the results are the same, no gateway.
I can manually add the route 'sudo ip route add default via 192.168.1.1'
and this will add it (just like I have done
in the network manager UI, but in both cases, i reboot without a gateway. thanks in advance..

In Network Manager, Edit Connections, choose the Ethernet entry as there
is presumably no other, then settings.

In the IPv4 tab, you will have Method as Manual, and there will be a
table for Addresses below.

You have your chosen static IP address, then the netmask, then the
gateway. What is in the gateway box? Are the characters correct, no
commas instead of full stops etc? I don't remember if NM will allow
malformed addresses, but this problem has to be something simple.

As I think others have said, if you are using a static address on a workstation, you would probably do better making the settings in /etc/interfaces in the old-fashioned way and not bothering with NM.

NM is useful on a travelling laptop where wifi is often used and
possibly VPNs. Having said that, I run NM on my workstation, but use
DHCP with a reservation on the server to provide a static address. It's
what Debian defaulted to, and it works, so I'm not fixing it.
