Networking stopped working on Ubuntu
- by 1337Rooster
I installed Ubuntu 10.04 through the Wubi installer (Funny, I installed it today and thought I would have gotten 10.10). I had a network connection and everything was working fine. I rebooted my coumputer a couple of times and then suddenly, I could not connect to the network and when I click the wireless/networking icon it says "Networking Disabled".
I reinstalled Ubuntu and the problem went away. After a few reboots the problem returned. I have tried restarting to see if it would come back as well as a few other things listed below. Any other suggestions would be appreciated.
Tried to restart networking via /etc/init.d/networking:
amato@ubuntu:~$ sudo /etc/init.d/networking restart
* Reconfiguring network interfaces... Ignoring unknown interface eth0=eth0.
[ OK ]
Tried to stop and start it:
amato@ubuntu:~$ sudo /etc/init.d/networking stop
* Deconfiguring network interfaces... [ OK ]
amato@ubuntu:~$
amato@ubuntu:~$ sudo /etc/init.d/networking start
Rather than invoking init scripts through /etc/init.d, use the service(8)
utility, e.g. service networking start
Since the script you are attempting to invoke has been converted to an
Upstart job, you may also use the start(8) utility, e.g. start networking
networking stop/waiting
Tried start networking:
amato@ubuntu:~$ start networking
start: Rejected send message, 1 matched rules; type="method_call", sender=":1.58" (uid=1000 pid=2241 comm="start) interface="com.ubuntu.Upstart0_6.Job" member="Start" error name="(unset)" requested_reply=0 destination="com.ubuntu.Upstart" (uid=0 pid=1 comm="/sbin/init"))
amato@ubuntu:~$ sudo start networking
networking stop/waiting
Tried service networking restart:
amato@ubuntu:~$ service networking restart
restart: Rejected send message, 1 matched rules; type="method_call", sender=":1.60" (uid=1000 pid=2248 comm="restart) interface="com.ubuntu.Upstart0_6.Job" member="Restart" error name="(unset)" requested_reply=0 destination="com.ubuntu.Upstart" (uid=0 pid=1 comm="/sbin/init"))
amato@ubuntu:~$ sudo service networking restart
restart: Unknown instance:
Here are the contents of my /etc/network/interfaces.
auto lo
iface lo inet loopback
I even tried to modify it to this (based on something I read, online, not sure if I was doing the right thing here). Tried everything again and no luck:
auto lo eth0
iface lo inet loopback
iface eth0 inet dhcp
