Intel 82579LM [8086:1502] Subsystem [1028:0498] Network driver for e1000 card not loaded on boot on beta 20.04

[Naveed Khan]

Hi

The symptons are:

I was running 20.04 Desktop Beta - everything was ok, I have an on board network card
00:19.0 Ethernet controller: Intel Corporation 82579LM Gigabit Network Connection (Lewisville) (rev 04)

After patching on 20th April - the network dissappeard - not the device mind you.

When you did ip a - you got

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host
       valid_lft forever preferred_lft forever

I tried downloading the latest as in the build on 20th but on boot from USB - it does not gring up the network

My hack - install another 100M pci card - this caused the network drivers to be loaded and both cards to work.
Current state of play:

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host
       valid_lft forever preferred_lft forever
2: enp5s2: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UNKNOWN group default qlen 1000
    link/ether 00:40:f4:28:8f:30 brd ff:ff:ff:ff:ff:ff
3: enp0s25: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000
    link/ether 18:03:73:d8:e9:94 brd ff:ff:ff:ff:ff:ff
    inet 192.168.0.25/24 brd 192.168.0.255 scope global noprefixroute enp0s25
       valid_lft forever preferred_lft forever
    inet6 fe80::1a03:73ff:fed8:e994/64 scope link
       valid_lft forever preferred_lft forever
6: enx424d7f654382: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc fq_codel state DOWN group default qlen 1000
    link/ether 42:4d:7f:65:43:82 brd ff:ff:ff:ff:ff:ff

enp0s25 is detected and working. If I unplug the ethernet to the 100M card that is a:
05:02.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8100/8101L/8139 PCI Fast Ethernet Adapter (rev 10)
then the network stops working!

Well weird.

Many thanks for the help. But I expect I cant be the only person with this issue the intel 1000m card is quite popular - the system is a Dell t1600 xeon

Hi

I downloaded the released 20.04 Desktop image. I get the same behaviour.
With no additional cards plugged in I do not get a network.
When I attach a WiFi USB - I get a wifi network
It says the wired card has no cable.

On main system boot
Once I plug in a USB WiFI card - the wired network and wireless become available.
A bug in NetworkManager?

I havr attacted to typescripts one when booted from istall media and other on the installed system

Hi

The problem was it was not loading the driver for the ethernet card.
I downloaded the latest driver from Intel - version 3.8.4 https://downloadcenter.intel.com/download/15817

Did a make install and then rebooted.

That fixed it. The card was recognised and lsmod shows e1000e loaded

Thanks

We'd still need this card to be probed automatically without external driver as possible. So I'm leaving this open.
