Having trouble installing a piece of hardware? Want to know if that peripheral is compatible with Linux?

Fried Network Card Alive Only in Windows?


Hi, I have a network card which has always worked with linux. Its an intel integrated 10/100. A few days ago it quit working (in linux), although the lights still came on. I was plugging and unplugging network connections from the card prior to the problem, so I figured I must have fried it. I have tried puppy and xubuntu livecds. Both state that there is no network hardware available although the device shows up in lspci, and dmesg says nothing. I tried resetting the cmos and leaving the computer unplugged for awhile to no avail. However, the device WORKS in windows xp, its the device I am using to write this right now. It still doesn't work in Linux anymore. Any ideas?

Did you make any serious system changes or updates prior to the point where the card stopped working? If you updated the kernel, it's possible that the driver for that card has either been removed or is broken somehow. Or perhaps there's a problem with udev or something like that.

Can you tell us exactly what chipset it is? What is the output of lspci?

Have you checked your network settings?

I vaguely recall discussion of an Intel NIC with firmware which needs setting a particular way for Linux to detect it and that Windows has to be used to set the firmware. Which NIC model is this? Perhaps all that plugging and unplugging upset it (or could Windows have changed the firmware config?).

I know it wasn't an update or setting, because I run linux off of my livecds. That's what I have been using as of late until I get time to really install gentoo. I was installing gentoo right before this started happening. It wouldn't have messed with my firmware would it? Here's the output of lspci:
Code:
02:08.0 Ethernet controller: Intel Corporation 82562EZ 10/100 Ethernet Controller (rev 01)

Good info

Possibly associated: Or it could simply be physical damage. Not suggesting you were rough with it but if it was "on the edge", cable un/plugging might have been the last straw. Intel's DOS-based diagnostics here.

I don't think it is damaged though, because its working right now. It's what I am using to post to you. I am browsing the internet just fine on xp. (Linux still says no device) The internet is also at the same speed as before. I remember the linux intel ethernet adapter bug, but that is for gigabit adaptors, and this is a 10/100. The port looks phsyically fine, and all the lights come on. Is there any network diagnostic tool I could run on linux?

So the hardware used to work under Linux, and is still OK (at least as far as Windows is concerned) and we can rule out Linux software changes because you are running Linuxes from CDs.

I can think of only one theory -- that the hardware/firmware has (been) changed in a way which makes in incompatible with Linux but still OK for Windows.

Here's interesting and suggests some things to try around Windows and BIOS power saving and sleep/resume ...

This is a related post. The OP never really said how he fixed it. Maybe if you PM him he can explain it??

EDIT: I think this is the part that worked for him, quoting Skaperen:
Quote:
Try completely pulling the battery from the laptop and leave it out for several minutes. An ability, even if not enabled, to have network packet cause the system to "power on" could leave the NIC and a few other parts enabled enough for the controller and/or BIOS code to be checking on this all the time, preventing the NIC from going to a cold reset state.

I did finally solve this problem. I left the computer unplugged with the power supply unplugged from the motherboard (otherwise capacitors may not discharge) and the cmos battery removed. After starting it up 2 days later the problem is gone. Good advice brucehinrichs!
