[SOLVED] network connection repeatedly being lost and gained

mark1977 · 2012-03-29 14:53:51

Hi,

I've just done a fresh install of Arch 64. About 1 minute after booting up, the network connection (eth0) is lost repeatedly and then regained. This makes it very difficult to use pacman. When I ping 3 packets only 1 is received.
Any idea what is causing this? I've followed the instructions on the network wiki, tried restarting the network.

Here is a screenshot I took:

Cheers,

Mark

To what what are you attached? Router, DSL Modem, Cable Modem?
What is the make and model of your NIC (look at the output of lspci -nn (That is two n;s, not m) It will give you two 4 digit hexadecimal numbers associated with your NIC card. Please report those as well.

At this point, I always ask,"Have you checked your cables?" You would not believe how often this fixed it

Lastly, are you using anything to manage the network? Wicd? NetworkManager?

EDIT: BTW.. (ewaller dons his moderator hat) In the future, if you would like to move threads, go ahead and use the report thread for the thread you want moved and leave a short note to the moderators. We are happy to move things for you; we usually get around to reports pretty quickly. I deleted your other thread.

Thanks ewaller for getting back to me, nice to have helping hand with this. Well the connection works fine from Windows or other linux distros, so I assume it can't be the cable. I'm connected to my router via a cable.

I can't type the whole output of lspci -nn but I believe the line you're after is:

04:00 Ethernet Controller [0200]: Realtek Semicondictor Co, Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller [10ec:8168] (rev06)

I am not using any network managers. This is a fresh install...

Cheers for the advice on how to move threads in the future

Posting at the end of my lunch break: That card is well supported on Linux, I'm surprised you are having issues.

I assume you have not been able to run pacman -Syu since your install (you said it was difficult ) So, you must be running the system that was on the install disk.

Can you verify which kernel you are using ( uname -a ) ?
If you boot from the install media, does the controller work as expected?

I'll try to get back later this afternoon; If not I'll get back this evening ( GMT - 7)

I'm guessing this could potentially be the issue you're facing.

Thanks Gcool that seems to have done the job - can't believe I missed that:)

Thanks ewaller too for your time. I can now use pacman

Edit: Immedaitely after doing this I rebooted and fouund I could not longer boot into Arch: https://bbs.archlinux.org/viewtopic.php … 4#p1080674
