Networkmanager snafu

Ask Fedora

Love fedora 44.
I seem to stumbled on a networking snafu.
The network manager found my ethernet hoever the default gateway was missing completely. This resulted in (at first) strange behaveour on mounting smb shares. Perhaps someone also has this ecperience or it is mainly on my side. for now it is fixed by adding networking setting in the gui.

Great work all developers on F44 :slight_smile: :slight_smile: it’s awesome

If you are using DHCP then the issue is the gateway is not being sent from the DHCP server I expect.

For all other systems in my home all works well except for the thinkcentre. Reinstalled and again same issue. All other systems goes well.

Perhaps a combination thinkcentre - fedora.

You could use wireshark to watch the DHCP messages and see if the gateway option is included from the router. Disconnect then connect to trigger the DHCP exchange.
I see in the DHCP ack a Router field with IP address of my IPv4 router.

I looked at the logs on one of my systems and see these:

I’m guessing you are missing the set default route message.

I shall check wireshark. However it does notexplain why other workstations in my network do get all info including gateway via dhcp Except thus one :slight_smile:

There is not enough information to answer that question.

That i know. :wink: Hopefully i can find someting in wireshark. But my guess is the problem is in the thinkcentre at the network port. I Just plugged in a wifi dongle and all works. If i know more, i post this.

Thanks 4 replying:)
