Today I did a fresh install of Ubuntu 7.10 and I discovered my wired internet was not working. I thought it could be my internet, so I booted XP - all well and good, back to Ubuntu 7.10 - not working, and then the 7.04 Live CD - all working.

The thing is, Ubuntu 7.04 deteced my wired network perfectly first time everytime, now in 7.10 thats a different story.

Really, a wired network should be just plug in and play. Has anyone else had this problem and is anyone able to help.

Thank-you in advanced

what does ifconfig say

ifconfig says:

those are the basic steps to debugging your connection,
ifconfig # get the card working
route or netstat -nr # check to see if we are on a network, can you ping the router?
can you ping the outside world? (see google IP address below) if so it's working and connected to your ISP
DNS get your nameserver working.


you have a connection, did you set up the IP address as 192.168.1.100?
if not you are DHCP.

what about route? (maybe netstat -nr )
there should be a few lines, with default pointing to your router box.
ping your router box
ping this.... (bbc.co.uk) 212.58.224.85
put this in your browser bar (ggogle) 216.239.59.147

if the above are true it's your DNS, now look at /etc/resolv.conf
ther should be a nameserver line in there eg:
nameserver 10.247.80.1

which will usually be your router box, but you could put other DNS servers if you like

see man resolver resolv.conf
