I recently updated the kernel to 3.12.6, but when I started my Fedora 19, all my network connections seemed to have disappeared (no more life signs of my ethernet card neither of my wifi card)

ifconfig shows nothing (except lo) and the same for the network icons on my desktop (cinnamon or gnome 3)

Booting on the previous kernel version 3.12.5 is my workaround for the moment, but if anyone have a clue or know how to report the bug, it will be most appreciated, as I am only a user :)

feel free to ask any required information needed !

For a start, I use some Lenovo T420 .


Last updates I did (since about a week) seem to have solved my problem. Kernel was not the issue apparently, because it was not altered.

Unfortunately, you probably don't want to try compiling the drivers yourself. The bug probably runs deeper than that and you will likely spend alot of time fixing it yourself.

I would increase the limit on the number of kernels that are installed:

edit /etc/yum.conf and edit installonly_limit until the issue is fixed.

Then after you did that, file a bug report, somebody will give you the commands required to help them pinpoint the issue.

They will likely require the output of dmesg for a well behaved kernel and one that is not well behaving. You can try dmesg | grep -i warning or dmesg | grep -i error.

You might try include the output of lspci as well, for example, I have the line

02:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 06)

which corresponds to my card(well controller).

Thank you very much for answer. I would have forgotten about the limits and I would have been very annoyed if the problem isn't fixed soon :)

and, could you please point me to where I am supposed to file the bug ? Fedora website ? or another more related to the kernel ?

Unless you know for sure that it is an upstream bug, you should file it to Fedora. The Fedora team then sends the bug upstream or makes a patch for Fedora until it gets solved upstream

The bug tracking website is

You should file your bug under the appropriate subsection.

You should also try and search for an existing bug and add yourself to that mailing list. Although that may be hard to find if it is your first time searching for bugs. The advantage is that you skip the triage step. If you file a new bug, it may take longer to get triaged.

I would also like to point out this answer.

I think it gives a better solution for keeping an older version of a kernel. You may want to try it if this problem persists.

hopefully some recent updates fixed my issue, but thanks for the link

Seems like ethernet and wifi drivers of your system are for kernel 3.12.5 - and yes, these are kernel specific stuff, and they refuse to work with kernel 3.12.6. One sure solution can be to recompile the driver source code for kernel 3.12.6 -:) But you can browse the web (and the NIC vendor site particularly) for the latest driver.

Hope it helps!

I certainly don't want to modify and recompile the kernel, haven't time to learn how to do that these days. But I will give a look if I can get the drivers elsewhere. Thank you for your answer.

I had the similar issue with WiFi and the same kernel version as you do. And problem was that I didn't have kmod package for my card drivers. My wifi card is: Network controller: Broadcom Corporation BCM43142 802.11b/g/n (rev 01) So I have to install broadcom-wl package. When I updated kernel my wifi was not functional at all. I solved the problem installing kmod-wl package.

thanks for the feedback, mine are :

Ethernet controller: Intel Corporation 82579LM Gigabit Network Connection (rev 04)

Network controller: Intel Corporation Centrino Advanced-N 6205 [Taylor Peak] (rev 34)

tried to do some yum search intel but the most "like my device" seem to be the package for Centrino 6000 (for wifi), and I already have it. I can't find anything for the gigabit ethernet controller in the Fedora repos

yum update and now everything seems ok.

I had this problem as well and did a yum update and the lan drivers started working off of copper LAN. Earlier versions of fedora like 15, 16 required extensive driver marking and configuration. Had a terrible time with it.

19 works great.

Thank you for your answer, but 19 isn't working for me on this point :(
