[Solved] Realtek Ethernet controller fails to connect.

dinosaur · 2011-07-21 00:18:48

Hey guys,
So I need help trying to get my Ethernet controller to work.

Relevant `lspci` line:

07:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 06)

During and after the Arch Linux installation (also had same results with Linux Mint install), eth0 has been unable to connect to anything, although eth0 does in fact show up on ifconfig.

Not sure if helpful, but after `ifconfig eth0 up`, result of `dhcpcd eth0`:

dhcpcd: version 5.2.2 starting
dhcpcd: eth0: waiting for carrier
dhcpcd: timed out

I have since tried to install two of Realtek's drivers (one r8169 and another r8168), but without any positive change.

So anyways, I need help, please. Whatever you guys need me to paste in order to help troubleshoot this problem I will gladly do. I just want this problem fixed as soon as possible.

Thanks!

* EDIT. Problem was in the Ethernet cord, not the Ethernet controller. My bad.

https://wiki.archlinux.org/index.php/Co … k_messages mentions your card and says you need to blacklist the r8169 driver in modprobe.conf and reboot.

Can you post the output of 'ifconfig -a'?

You may want to try http://releng.archlinux.org/isos/ as the official isos have a pretty old kernel.

Yeah, I saw a lot of things like that, but I don't get any "eth0: link up" in dmesg like the wiki says.
Output of `dmesg | grep -E "(eth0|r8169)"`: http://paste.pocoo.org/show/443197/

Sure. http://paste.pocoo.org/show/443196/

Okay, will do.

Wait, you have wlan running? So maybe you can just update your system - you will get the current kernel and more! :-)

Haha, I have updated my system with wlan0. Didn't solve the Ethernet problem though...

Just to be sure, does your updated system show you're running dhcpcd 5.2.2 (as in your first post)? We're using dhcpcd 5.2.12 atm.
Or are you saying you've just updated it?

Are you using r8168 now?

Sorry for the confusion. I ran those commands from the LiveCD because that was most similar to the vanilla install before I made any changes. On my actual install, I have updated packages, including dhcpcd which is at 5.2.12, and my kernel, which is at 2.6.39. Although the updates haven't really changed anything, at least as far as I can tell.

Yes, since my install I have experimented with other drivers, and right now I'm using Realtek's version of r8168. Found here: http://www.realtek.com/downloads/downlo … down=false
Current `dmesg | grep -E "(r8169|r8168|eth0)"`: http://paste.pocoo.org/show/443231.

*Edit: I have also blacklisted r8169 in modprobe.conf like you suggested.

I'm not sure what the difference is, but you can use https://aur.archlinux.org/packages.php?ID=27000

Does it work with some liveCD? Maybe it's a configuration problem.

Looks to be the exact same driver I already have installed, but I still appreciate the find.

So far I've tried it with Arch Linux and Linux Mint. Maybe I'll give some other distros like Gentoo, Fedora, or whatever will be most promising for hardware compatibilty a try.

Turns out the Ethernet cord I was using was messed up. Plugged in a new one and it worked. *sigh*
