After upgrading from 7.04 to 7.10 internet broken.

So a ping to www.ubuntu.com resolves ok?

And Firefox cannot get to www.ubuntu.com?

That's odd.

Are you able to run the following from a terminal window?

sudo apt-get update
sudo apt-get upgrade

The browser is now showing "connected to www.___" and I can surf www.newscientist.com, any page on my homepage site! But as soon as I leave this site I get the "connected to xxx" and nothing loads.
sudo apt-get update shows "5% Getting Headers" and the modem lights show some comms every 5 seconds or so, but thats as far as it gets.
Thunderbird sends the password to ISP but 30 seconds later gives "Unable to connect to server" error. Yet this dual boot of 8.04 works fine.

What does ping www.ubuntu.com show?
Does firefox open www.ubuntu.com?
The www.newscientist.com is cached from a previous working session, I am presuming, rather than a currently working connection.

ping www.ubuntu.com gives reply from ubuntu's IP address.
Firefox cannot open www.ubuntu.com.
I guess www.newscientist.com is cached.
Also running pppoeconf in terminal "failed to find the access concentrator of your provider".
Thanks for your help!

try this in firefox and let me know what it shows

Hello

Hmm, mine works perfect like this (My /etc/network/interface):

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# This is a list of hotpluggable network interfaces.
# They will be activated automatically by the hotplug subsystem.
auto eth0

# The primary network interface
iface eth0 inet static
address 192.168.1.100
netmask 255.255.255.0
gateway 192.168.1.2

and maybe the problem would be pci related

Add the pci=noacpi boot option and try

A bit more info on the above: Give the following command in a terminal (applications -> accessories -> terminal)

 gksudo gedit /boot/grub/menu.lst

Then add "pci=noacpi" to the end of the # defoptions line:

    # defoptions=ro quiet splash pci=noacpi

Your defoptions line may differ a little, just add the recommended text to the end of the line, save the file, then close the editor.

Afterwards, in a terminal, run:

    $ sudo update-grub

This will update grub to use the new option. Afterwards, reboot, and then run the system again..

Thanks for your help.
Tony, tried http://91.189.94.251/ but got "waiting for www.ubuntu.com" but nothing further.
Bhavani, added "pci=noacpi" to menu.lst and updated grub then rebooted, but no change.
Any ideas?
Thanks again,
Steve.

That should have opened up www.ubuntu.com
Can you boot from the Ubuntu 7.10 live CD and get onto the internet?

Hmm according to this

https://wiki.ubuntu.com/HardwareSupportComponentsWiredNetworkCardsRealtek

your nic is reported working and auto detected in ubuntu 8.04

One easiest way is to upgrade your os to ubuntu 8.04

Regards

Bhavani Shankar.

Bhavani,
Yes but my Nvidia 6600GT video card simply wont run on 8.04 (see question 34223) and 10 minutes on 60 Hz refresh is anyones limit!

Tony
7.10 live cd wont access internet either.

Thanks for your help.

I'm a little confused now.
Are you on version 7.10 (this question = #34186) or 8.04 (#34223)?

I would recommend that you go for 8.04 in terms of getting the network support sorted.

I have posted in #34223 regarding your nvidia issue on 8.04. The nvidia 6600GT is a common card, I would be surprised if we cannot help you get it working, even though it is taking some time to resolve.

I am dual booting 7.04 upgraded to 7.10, and 8.04.
I added 8.04 to ensure everything worked in it before upgrading and breaking even more stuff! And to get a working browser.

The original plan was to upgrade to 7.10 then 8.04. But browsers and synaptic just wont work in 7.10. So no upgrade to 8.04!

I guess backup, format and start again with 8.04?

Steve,
If you can afford to reimage and start again with 8.04 CD then that would be the preferable option.
The network support is definitely better.

Do you have any important data on this machine or can you just wipe and start again?
