Ethernet Card Not Detected in Linux
Posted: 21 Jan 2018, 20:06
Hi Yogi
I have a real poser this time.
A friend gave me his Dell Optiplex 755, it's not a full-size desktop. I think they call it Small Form Factor? About half the size of a normal cabinet.
I partitioned the drive and have the original program WindowsXPPro, and added Debian, Linux Mint, and Ubuntu, each on their own partition.
The Ethernet Card works just fine using Windows. It's an Intel 82566DM-2 on-board.
It does not work with any Linux distro, not even the older ones I've tried.
The proper drivers e1000e are loaded with each OS.
lspci shows the controller OK.
ethtool eth0 shows No Such Device, however
ethtool enp0s25 shows it and how all the default settings are set.
Got that enp0s25 using ifconfig, which showed it instead of eth0
The last line of ethtool enp0s25 shows Link detected: no
Other details:
While the computer boots up, the Ethernet Card shows a green light.
If I boot into Windows, the green light goes out after post boot, and while Windows is loading then changes to orange, also the light on my Ethernet Switch is on, as it should be.
However, if I boot into any of the Linux Distro's, the green light goes out after post boot, but never comes on after Linux is loaded, and there is no light on the Ethernet Switch, showing the card is not on.
I keep getting the Ethernet Disconnected Warning every 30 seconds, and it tries to connect.
I've tried numerous things I found on-line to try, including creating a new connection in the network manager for the enp0s25.
Heck, I tried so many things over the past couple of days, it would fill a page.
Just curious if you've ever hit a problem like this, and found a solution?
Those folks on-line who finally got theirs working did so by buying an external USB ethernet dongle, or they wrote some new program to force the link or changed enp0s25 to eth0. I tried that and it didn't work for me.
It's no biggie, this is a small computer with only 2 gigs of memory. I was going to use it for when I was doing my writing, but would need the internet working to do that. It does not have UEFI, and I've tried a few bio's settings that have to do with the ethernet card settings. None of them made a difference either.
I can't post what I get from the codes used without a connection to nab them, hi hi.
Thanks!
