REALTEK RTL-8100/8101L/8139 UNCLAIMED, Gnome Ubuntu 14.04

[mac75a]

Hi,

I have two wired cards in my system (Gnome Ubuntu 14.04) and I have some problems with them. Some months/years ago I plugged an old REALTEK RTL-8100/8101L/8139 card because the system "refused to detect" (probably it was unclaimed) the RTL8111/8168/8411 PCI Express Gigabit mounted on my mobo (my system was not 14.04, but an older release). Now, with a fresh install of Gnome Ubuntu 14.04, the system sometimes gets both cards enabled, but other times the RTL-8100/8101L/8139 card is not claimed and I don't know why.

I paste the output from some commands. It is in spanish, but I think that no translation is needed (if it is, please tell me). Well, "NO RECLAMADO" means "UNCLAIMED".

I added 8139too and r8169 to /etc/modules to force the system to load these modules...

$ cat /etc/modules
# /etc/modules: kernel modules to load at boot time.
#
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with "#" are ignored.
# Parameters can be specified after the module name.

Please, can someone post any clue about why the card is not always claimed? (yesterday it worked perfectly... today I rebooted 5 times and no luck, so I have to use the other card... But maybe tomorrow this card will not be claimed...)
Can it be a conflict between both realtek cards? (it sounds weird though...)

Thanks in advance!

This card regularly loads two drivers:


8139too 33544 0
8139cp 27953 0
Blacklist the wrong one:


echo "blacklist 8139cp" | sudo tee -a /etc/modprobe.d/blacklist.conf

Thanks for your answer, praseodym.

The module 8139cp is loaded even if I blacklist it:

$ cat /etc/modprobe.d/blacklist.conf
[...]
blacklist 8139cp
blacklist mii


I tried blacklisting mii as it seems to use 8139cp, but even so, both modules are loaded:

$ lsmod
[...]
r8169 67581 0
8139too 33544 0
8139cp 27953 0
mii 13934 3 r8169,8139cp,8139too

[praseodym]

Run:


sudo modprobe -rfv 8139cp 8139too
sudo modprobe -v 8139too
sudo depmod -a
sudo update-initramfs -u

[mac75a]

OK, 8139cp is not loaded any more.



$ lsmod | grep 8139
8139too 33544 0
mii 13934 2 r8169,8139too


But even so, the card keeps unclaimed :-(

Thank you very much for your help!

Is the cable plugged there?

[mac75a]

No, the cable wasn't plugged in that interface, but in the other one. When I plugged the cable nothing changed. But after two reboots with the cable plugged, suddenly it became claimed and started working...

I did some more reboots with the cable plugged, and again it became unclaimed.

After that I decided to test booting from a Windows partition, and it said that the network card could not be initialized (it was recognized in the devices management section, but with a yellow warning sign on it), and the green led of the card was off (the cable was plugged). I rebooted from Windows partition again, and this time the card worked perfectly.

I did some more reboots from Ubuntu and now it seems that the card is always claimed and it works...

So, it seems that is a hardware problem with the card or the mobo, because it is very strange that it works randomly, and it stops working without any reason in Ubuntu and in Windows...

I will mark the thread as solved (if I guess how to do it :) ). Thank you very much for your help, praseodyn!

Regards.
