When I was installing XBMC Live I got a "network autoconfiguration failed" message during the DHCP configuration. Then I manually configured the network settings with the following:
IP - 10.0.2.15
Gateway - 10.0.2.1
Mask - 255.255.255.128
DNS - 8.8.8.8 and 8.8.4.4

I got through the installation fine and XBMC is running, however I have no network access.

When I go to /etc/network/interfaces I see:

Code:

# This file......
# and how....

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto eth0
iface eth0 inet static
         address 10.0.2.15
         netmask 255.255.255.128
         network 10.0.2.0
         broadcast 10.0.2.127
         gateway 10.0.2.1
         # dns-* options are implemented by the resolvconf package, if installed
         dns-nameservers 8.8.8.8 8.8.4.4
         dns-search dummy.net

The I changed the last part to:

Code:

auto eth0
iface eth0 inet dhcp
         # address 10.0.2.15
         # netmask 255.255.255.128
         # network 10.0.2.0
         # broadcast 10.0.2.127
         # gateway 10.0.2.1
         # dns-* options are implemented by the resolvconf package, if installed
         # dns-nameservers 8.8.8.8 8.8.4.4
         # dns-search dummy.net

Entered:
$ sudo ifdown eth0
$ sudo ifup eth0

I got "Bound to 10.0.2.15" and apt-get update worked fine. But if I reboot I get no network again and have to repeat this.

My system is a Asus AT5IONT-i and it's connected by wire (no wireless card).

I had the same problem, using the same MB - AT5IONT-I.

Fresh install of XBMC and no network connection. The same happens after fresh install of Ubuntu 10.04.2. I didnt find any post anywhere related to this MB, everybody says it works without problem.

I solved it by changing cable and connection to different port of my switch and magically automatic network configuration works well and I am online (XMBC and also Ubuntu 10.04.2). I know, stupid advice, but try it.
I really didnt change anything more and it works again.

this is the default entries on /etc/network/interfaces

before you reset this enter this command on terminal

Code:

[b]ip addr flush eth0[/b]

then reset your /etc/network/interfaces then restart networking or reboot.

Code:

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet dhcp

change them to this and retry

Hi. Thanks a lot for your help but I think I finally found a solution. Used the jumper on the board to clear the BIOS and now everything seams fine. I plug a USB drive with Ubuntu 10.04LTS minimal and network configured automatically.

slamka, I had already tried that. I also connected the cable to my MacbookPro and it worked fine, so no problems there. Thanks anyway. And it's not a stupid advice. Stupid is giving up without trying everything.
