View Full Version : Ubuntu dropping network connection

28-10-2009, 09:23 PM

I have an Ubuntu 9.04 box that I tend to keep turned on all the time. The PC has a static IP assigned and seems to work fine after a restart but after a few days/week 'something' happens and the connection drops. After this the computer can no longer be pinged, can't ping out or access any network resource.

It can still ping itself (localhost/own IP) but anything else I try and ping I get a 'network destination unreachable'.

If I restart the computer again it will start working fine. Anyone know what the could be? Disabling/enabling the network interface does not fix the problem. I've done any system updates that were available.

Thank you,

So I did some more fiddling around and found that by running:

sudo /etc/init.d/networking restart

it seems to fix the issue. Although that doesn't really fix the problem permanently. I've also removed the static IP and set up a DHCP reservation on the router to assign it that same IP, maybe this will fix the issue.

Feel free to share any views as I still don't understand why it happens :)

Sounds more likely to me to be a hardware issue?? Do you have another network card to try?

Is the existing card PCI - is it seated properly?
