Ethernet Gone from HP d530 Desktop / Ubuntu 12.04

Asked by Julianloui on 2014-09-16

2014-09-16

I used to be able to see my HP d530 SFF computer's integrated Broadcom ethernet hardware listed in the BIOS PCI Devices section but no longer. Neither do I see it when I enter the 'sudo lishw' command in Linux. Does this mean that the ethernet driver has gone bad or been deleled somehow?

My d530 is now running Ubuntu 12.04 as its only operating system.

I've used commands such as lshw, iwconfig, inxi, etc. only to find nothing related to the ethernet hardware. When I run Browser Linux on this computer, I also see only local loopback and wlan0, but not eth0.

Any help will be much appreciated.

If you reset your BIOS to default settings does it appear?

How do you reset BIOS to default?

Julianloui

Power off the system. As soon as it powers up a little, repeatedly tap F10 on the keyboard.

Andrew,

PCI Devices still fails to show the ethernet after a BIOS reset.

What is the output of:

sudo dmidecode -t 1

Andrew,

By the way, Ubuntu didn't accept 'sudo dmidecode -t l'. So I issued 'sudo dmidecode -t bios' as a substitute and got the above output. I hope I did it right.

Julianloui

You could try the 3.17 kernel from the Kernel PPA, otherwise all I can suggest is that you update the BIOS and test (be very careful. It may require Windows) If all else fails I suggest you report a bug.

If you super want to use Ethernet you can buy a compatible PCI Ethernet controller for pennies and use that. You may even have a buddy with one s/he can give you

Andrew,

Since my HP d530's ethernet 'card ' is integrated into the motherboard, I have no way to replace it with a discrete card.

As for trying the 3.17 kernel or updating the BIOS, I'll consider them as future alternatives. I think I can continue putting up with using a wireless connection for this particular computer. After I installed Linux Mint 17 as a companion O.S. to Ubuntu 12.04 last night, everything works quite well and fast in Mint.

Many thanks again.
