You have been subscribed to a public bug: I installed Ubuntu Server 12.04 i386 with no network connected to the computer; the network chipset was however properly found and installed.
After the successful installation of Server with the inclusion of SSH, LAMP, Postgre SQL, and SAMBA, I booted up the PC. All was Ok so I ran "sudo shutdown now" and moved the server to it's permanent location where I hooked it to the network and booted it up. At this point, it should have gotten a DHCP address, but did not. So I edited the /etc/network/interfaces file and setup static IP to an unused IP in my network (10.1.1.252). At this point I could ping my other computers and my other computers could ping it and could connect via SSH and could see the default webpage from the LAMP install. That said, the Ubuntu server COULD NOT ping my gateway which has an IP of 10.1.1.254. The really weird thing is that my gateway COULD ping the Ubuntu server! Here's more information on my config: My network uses 10.1.1.x for the IP. My gateway is 10.1.1.254. The Ubuntu Server is 10.1.1.252. >From my windows laptop I login to the server via SSH no problem. ALL local connectivity works, EXCEPT from the server to the gateway.

I will be unable to further test as I must get the server up and running so am beginning a reinstall now. ** Affects: network-manager (Ubuntu) Importance: Undecided Status: New ** Tags: bot-comment -- Installing Ubuntu with network disconnected causes major network issues https://bugs.launchpad.net/bugs/1019614 You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. -- Mailing list: https://launchpad.net/~desktop-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
