Ethernet Connection no longer works

**GazFighter** · March 2nd, 2009

I'm just gonna give up on 9.04 until April. I'm gonna reinstall 8.10. Thanks for the help though.

I see you got an ip address, so your not to far away from getting a working connection. Check /etc/reslov.conf to see if you have the correct dns addresses.

I don't know if we had the same issue, but I had this problem when I did not let grub auto update the kernel list during the upgrade. If you are still booting into the old kernel for intrepid, run update-grub and boot into the new kernel.

I have to configure my ethernet connection after every restart with ...

Code:

sudo pppoeconf

Does anybody know the reason and how to solve the problem?

I had the same problem. Wifi was working, nm said eth0 was not managed.
i solved it by editing /etc/NetworkManager/nm-system-settings.conf where I changed

Code:

[ifupdown]
managed=false

to:

Code:

[ifupdown]
managed=true

and /etc/network/interfaces where I commented out iface and added auto eth0)

Code:

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto eth0
#iface eth0 inet dhcp

Hope this helps

Now it looks like this but the notifier still shows "no network connection" although already online and Firefox starts in offline mode.

Code:

auto lo
iface lo inet loopback


iface dsl-provider inet ppp
pre-up /sbin/ifconfig eth0 up # line maintained by pppoeconf
provider dsl-provider

auto eth0
#iface eth0 inet manual

Since Alpha 6 Firefox recognizes my Internet connection, if I change my Firefox network preferences to "auto"!

Hmm ... Firefox starts again in offline mode.

Is it possible to enable "work online" by default?

**ubu-for** · March 13th, 2009

Now I've found out that if I close Firefox, start Synaptic, download and install some packages, close Synaptic and start Firefox again, the option "work offline" is unmarked.

Hmm ...
