Mageia forum

I'm experiencing a weird problem I've never encountered before. I'm having a hard time connecting to my home network (wired LAN) and naturally to the internet. The connection is erratic at best. I sometimes cannot connect at all for minutes, but mostly it's just on-and-off connection. It's like 2 to 10 seconds connection on and then it's off again for a similar (or longer) period of time.

First of all, this is my first 64-bit linux desktop. I installed it from a downloaded Mageia1 64-bit DVD and have since installed sources and updated the system. The PC is a dual boot with Win7 pro. Within Win7 the connection works like charm - no problem. All other wired and wireless connections in my network work fine - it's just this one system that doesn't seem to work.

The LAN module is integrated to the motherboard and the model is ASUS P8-Z68-M Pro.

I have two Zyxel ADSL/LAN/WLAN gateways (P-661HNU and P-661HN) and I've tried them both (only one at a time operating in my network). The results are the same with both of them. I've also disabled firewall and MAC filters within Zyxel, but no help.

I've also tried with both automatic (DHCP) or fixed IP configuration.

I don't know, but I would rule out hw-failure as it's working without problems in my Win7 Pro installation.

Here's copy of my ping tests (.254 is my gateway and .9 is the problem PC's fixed IP):

Any help is greatly appreciated!

Are you using a PPOE and if so, which machine is doing the connection?

Have you tried changing cables, if that is an option?

Finally, turn off and unplug your computer to reset the integrated LAN on your computer. I would suggest 5 minutes. All I know it has something to do with resetting WOL that sometimes works.

Also, may seem simple... but make sure you do NOT have an IP conflict. That would do it.

I've changed the cable also, but as I said everything works like charm under Win7 Pro (64-bit). So that's not it. And I'm not using Wake-On-Lan (at least not to my knowledge).

I always turn this PC off for the night (i.e. several hours at a time) and I've changed the PC between Win7 and Mageia several times during the day (thus turning it off quite often).

Thanks CaptSilver, but no, that's not the case. I keep a list of all IPs in my home network. And as I said, I've also tried it with automatic IP configuration (DHCP enabled also in the Zyxel boxes).

If, as root, you run

Code: Select all

tail -f /var/log/messages


in a terminal window, are there any helpful (or unhelpful!) messages relating to the network connection as the connection comes and goes?

OK, this is how shows up in /var/log/messages file. At this same time I tried pinging (a bit further down the ping messages)

OK, this is how shows up in /var/log/messages file. At this same time I tried pinging (a bit further down the ping messages)

- EDIT - This .100 is one of my mounted network storage that the system is trying to connect.

Google found this http://forums.gentoo.org/viewtopic-t-885238-start-0.html which looks a bit like your problem. Can you post the output of

Code: Select all

lspci -nn | grep -i eth


(again run in a terminal as root), which should identify exactly which ethernet device you have.

You can also try booting with pci=noacpi in grub to check to see if some sort of power saving mode is causing it.

OK, thanks martinw and CaptSilver. I'll check these tomorrow and post back.

Here it is.

03:00.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller [10ec:8168] (rev 06)


I had a look at the instructions on the Gentoo and further on Ubuntu forums, but the solution seems quite tricky. First of all, I would need to build the new kernel driver, and I don't know if I know how to do that. Then if I manage to do that, I would have to do that every time the kernel is updated. And that would be real pain in the behind...

Maybe I should just go ahead and by me a new NIC. The problem is that I have only one PCI slot left in the motherboard. Then I would not have any room for any other cards left.

OK, managed to get the network to work properly. Now my problem is that it's not automatically loaded. How can I get that loaded automatically?

What did I do?
I downloaded the package from Realtek's pages:
http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=13&PFid=5&Level=5&Conn=4&DownTypeID=3&GetDown=false#2
I removed the old package as instructed in ubutu forum:

Code: Select all

-> rmmod r8169
-> mv /lib/modules/`uname -r`/kernel/drivers/net/r8169.ko ~/r8169.ko.backup

Then I unpacked the files on my desktop:

Code: Select all

$ bzip2 -d r8168-8.009.00.tar.bz2
$ tar -xf r8168-8.009.00.tar
$ cd r8168-8.009.00


And as per the Readme file in the package, I ran the autorun file:

Code: Select all

# ./autorun.sh

Check old driver and unload it.
Build the module and install
DEPMOD 2.6.38.8-desktop-9.mga
load module r8168
Completed.


And that works like a charm. At least until I reboot the system and I will have to run that autorun again.
How can I make the module to run automatically?

You need to add it to file /etc/rc.d/rc.local.

Code: Select all

/path/to/myshell.sh

and boot your system and it will load it automatical on every boot.

You may need to set that script to executable first i think command it is
firs su root and that command

Code: Select all

chmod +x autorun.sh

Thanks ozky! That worked.

I had the Realtek package untarred to ~/Programmes/ -directory
Here's what I added to /etc/rc.d/rc.local file:

Code: Select all

cd /home/dude67/Programmes/r8168-8.027.00/
./autorun.sh
