BCM57780 Driver

I have installed 15.4 on a Dell Studio xps 8100. It has a BCM57780 Gigabit Ethernet PCIe device which does not seem to connect. lspci lists it. I can find the mac with ip a. There are no lights when I connect the network cable (tested on other machines). I have a USB WiFi dongle which works fine. I can’t seem to find a driver in YAST or in other internet searches.
Can anyone advice on how to get the interface working?


Please share the output of

inxi -Na
  • You can save the output to a text file on a memory stick, and transfer here via an internet connected device.

Even with just the BIOS active (no distro booting), I would expect to see the ethernet port lights if connected to an active device.

You could also check the status as reported by ethtool command. Refer to ‘man ethtool’ for more info.

Studio:~ # inxi -Na

Device-1: Broadcom NetLink BCM57780 Gigabit Ethernet PCIe vendor: Dell
driver: tg3 v: kernel port: N/A bus-ID: 04:00.0 chip-ID: 14e4:1692
class-ID: 0200

Ok, that confirms that the tg3 driver is loaded as expected. Did you also examine the link state with ethtool (with ethernet cable plugged in)?

BTW, when posting commands and output please use the preformatted text button </>.

Faulty NIC hardware?

Or cable?
Defect? (just filling in to get to 20 characters)

Could be, I guess. When I see the guy that gave me the computer, I’ll ask if it was working. The cable has been tested with another computer on the same router and port.

The OP checked the cable already.

Just in case the advice in this post is of value here…

Thanks for that. I can’t find that text in the service manual. Might we have different versions of the manual?

I was really pointing you at the suggestion in the post, not the service manual they refer to. :wink:

I had seen that post. My PCI card just arrived. I guess I’ll test it out later tonight.
