Wired connection fails after booting.

English Install/Boot/Login
1

After a reboot, which occurs almost every other day with Tumbleweed I find I have no network connection. If I left click on the Network Manager widget the Networks window opens and shows two wired connections:-

Wired connection 1 (eno1)
Wired connection 1 (enp0s26f1u2)

On first starting the wired connection starts on the “wrong” one, ie. the one which fails to connect and work. If I select the other connection, I believe eno1, the first connection is disconnected and the other one connected and then it all works.

What is going on, what is “enp0s26f1u2.” Looks like part of an IPv6 address which I never use because I do not know how. Do I have some configuration incomplete? Should something be turned off somewhere?

Regards,

That’s the longest lspci output I’ve ever seen! :frowning:

Does this PC have more than one physical Ethernet port? If yes, can it and is it disabled in BIOS?

Does this PC have a BIOS update available? If yes, please install it and see if it helps. If not, I would file a bug report on https://bugzilla.opensuse.org/.

Probably some USB device. It is plugged into

Probably this one

           Device-3: IBM RNDIS/CDC ETHER type: USB driver: cdc_ether

eno1 is onboard LAN port.

There are autoconnect and autoconnect-priority NetworkManager connection options which you can use to tune which connection is selected for autoconnect.

Hi and thanks for the suggestion. I went into the BIOS and was well out of my depth. There are several layers of options in different sections of the BIOS configuration and I do not understand or recognize any of them. Nothing simple like disable ethernet card 2. Have retreated and left alone.

7

Thanks for the suggestions. There is a USB device connected which works with my remote KVM switch. That seems plausible but this setup has been working correctly for years. Must be Tumbleweed has changed things.

I was not sure about auto-connect priority. I can only examine these devices when not connected. The other option was to uncheck the auto-connect on the one with the “enp0s26f1u2” description so I unchecked this one and connected to the eno1 port and re-booted. Not a good plan!

I am now working on another machine as I cannot boot the problem machine at all. It stalls with failing to connect NFS drives so I cannot get back to reverse my change.
Will try a few more boots but may need to seek help here again.

8

The machine came back up eventually with no network connection.
The priorities on both wired connection 1 are set at -100. To what should I set the connection which works to give preference to this one?

9

This machine is now almost useless as the frequent reboots required for Tumbleweed and this problem with network devices is taking too much time.
I have tried disabling the interface with the strange name but that causes problems shutting down as well as starting.

I am not getting any help here with what priority figures I should set but it does appear that both devices are being used so perhaps the USB connection is the problem. I do NOT however have this problem on an identical machine running Debian.

Options appear to be changing to wicked and giving up on Network Manager. If this fails I may have to go to openSUSE version.

I shall post this now on the network forum where others may have had a similar experience.

10

Just a follow up in the unlikely event that others have this problem. The problem is caused by a driver which has been created (by M$) to enable a USB device to access a network. Unfortunately I have been unable to stop this even though the feature has not been configured and is not wanted. Changes to configurations have only delayed the booting process by (by minutes) so I have now switched to wicked and given up on Network Manager.
All is now working as it should and the unwanted additional “network device” is ignored.

Time flies when you are having fun with Tumbleweed. Every day brings something new and often unwanted!

11

So check your other thread for the same topic…
https://forums.opensuse.org/showthread.php/540526-Network-connection-fails-after-booting
We have shared advice there…NM can be made to ignore interfaces as desired, and you can also make a connection not “auto-connect” if desired. Not hard to alter existing network connection profiles.

Thanks again Deano,
I have the other thread and will look again when I have a quiet moment.
Budge.
