Hi all,
I am having a major problem on one of my systems with a network controller.
The system has the Intel DQ77MK motherboard. This board has dual NICs.
The first NIC, an Intel 82574LM works fine and is called eno1
The second NIC, an intel 82574L is the problem.
The second NIC is called rename3, or sometimes rename2 / rename6 or
rename7 etc.. It keeps changing.
Whenever I try to apply any configuration to this NIC it changes name
again, therefore I have no network connection. So I change the name in
the config and the NIC changes name again.
I have never seen a NIC called rename before. What is this trickery?!?!?
The system is running ubuntu 18.04. Now I have probably confused you by
posting on the OpenSUSE list, but the fact is I have posted on the
Ubuntu forum and it has been 4 days and I have had no reply what so
ever. It is still Linux after all, so hopefully one of you might be able
to assist?
Ubuntu 18.04 uses netplan to manage the network configuration. I intend
to set up an bond in balance-rr mode as I have done on another system
without issue.
How can I go about diagnosing this? This is the first time I have every
had a NIC not work in any linux distro (apart from broadcom wifi drives
cough cough..) so I have literally no in-depth knowledge of networking
in linux.
so basically... HELP! lol
First things I checked:
Output of lspci:
paul@s34:~$ lspci | grep net

Connection (rev 04)
03:00.0 Ethernet controller: Intel Corporation 82574L Gigabit Network
Connection
Output of ifconfig:
paul@s34:~$ ifconfig -a
