Ubuntu 8.10 Internet help?

Since DHCP fails (because it keeps trying the same IP as our other pc) I have followed this guide http://www.cyberciti.biz/faq/setting-up ... aces-file/ and I think I should have something like this...

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet static
address 192.168.1.15
network 192.168.1.0
netmask 255.255.255.0
gateway 192.168.1.1

This lets me access my other computer over the network and the router it self, but not the internet. Here is a list of what I can and can't do :/

I can...
Ping websites
Trace Routes to websites (tracert under windows?)
access router
access network

I can not...
browse internet
download packages
download updates

I have tried defining correct settings using the GUI Network configure thing but defining a manual IP there doesn't even give access to the network (even though it says it is connected o_o) or anything which is why I am trying the manual approach.

edit: I am connected using a Ethernet card and a Ethernet cable connecting my card to the router which is connected to the wall.

it should not be getting an ip address identical to others, there is something up with your DHCP server on your router.

that being said, has it ever occured to you to wonder where its getting the DNS info from?

when was the last time you rebooted/reset your router? it sounds like it needs it if the dhcp server is doing retarded things.

The router is switched off every night, I have tried manually configuring the routers DNS settings. The router and internet/network work fine under Windows XP and Vista which is odd...

You need DNS information.

Look in the /etc/resolv.conf file. It should have a line
nameserver 192.168.1.1

If it doesn't, then it can't look up names, which means no internet. You can add the line anywhere in the file.

If you ever switch dhcp back on, the dhcp server will likely overwrite this information. There is an option to tell it not to do this, but it's not springing to mind.
