 Posted: Tue Mar 20, 2018 4:04 pm Post subject: Network interface disappeared after bios update |
 |
|
Hi Everyone,
I hope someone can help. I have updated my computer with the newest BIOS and now networking stop working. Before I made the BIOS update my network interface was working fine - 6 months plus. It is a r8169 Gigabit Ethernet and named enp33s0 (looking in dmesg, it seems to be called eth0 now but I have tried to add it as eth0 and still not working).
Syslog tells that the interface net.enp33s0 does not exits and therefore fails to start.
To be sure, I have recompiled (with the same settings as before) the kernel and modules but no luck.
All help is appreciated.
Regards Stig |

It looks like you're back to as if you were installing the network for the first time once more.
Assuming you're using static setup, openrc. So you have /etc/conf.d/net with config_eth0=xxx and the symlinks from /etc/init.d/net.eth0 -> net.lo ?
If you manually set up that eth0 device, does it work?
This is strange that the persistent device names didn't work, but with an ACPI/BIOS change, all bets are off. I've had one motherboard whose ethernet simply died with a bios change... that was annoying.

Thank to both of you. How do I find the new persistent name? Do you know a cmd? |

You are right. It did change the persistent name to enp30s0. The command I used to find the name was:
Thank you again - this solved my problem. |
