Try ping'ing a known IP address from a terminal window. www.ubuntu.com translates to 82.211.81.166, so try: ping 82.211.81.166 If that works, then try: ping www.ubuntu.com and if that doesn't work you have a dns problem. Check out contents of /etc/resolv.conf and then see if the addresses of the name servers are reachable via ping.

We can do this by running "ip route" mojo-jojo david% ip route 10.187.182.224/27 dev eth0 proto kernel scope link src 10.187.182.233 default via 10.187.182.225 dev eth0 >From this we can see that our default route is to 10.187.182.225 using eth0 network device. Lets try pinging that: mojo-jojo david% ping 10.187.182.225 PING 10.187.182.225 (10.187.182.225) 56(84) bytes of data. 64 bytes from 10.187.182.225: icmp_seq=1 ttl=64 time=0.317 ms 64 bytes from 10.187.182.225: icmp_seq=2 ttl=64 time=0.291 ms 64 bytes from 10.187.182.225: icmp_seq=3 ttl=64 time=0.224 ms --- 81.187.182.226 ping statistics --- 3 packets transmitted, 3 received, 0% packet loss, time 2001ms rtt min/avg/max/mdev = 0.224/0.277/0.317/0.041 ms So we know we can at least reach the router. Now, lets see if we can get any further than this. Lets try pinging Ubuntu's webserver. mojo-jojo david% ping 82.211.81.166 PING 82.211.81.166 (82.211.81.166) 56(84) bytes of data. 64 bytes from 82.211.81.166: icmp_seq=1 ttl=52 time=30.5 ms 64 bytes from 82.211.81.166: icmp_seq=2 ttl=52 time=30.8 ms 64 bytes from 82.211.81.166: icmp_seq=3 ttl=52 time=30.2 ms --- 82.211.81.166 ping statistics --- 3 packets transmitted, 3 received, 0% packet loss, time 2006ms rtt min/avg/max/mdev = 30.232/30.532/30.836/0.318 ms If this works, then we have working networking and can move on to checking DNS. If this doesn't work, we need to find out where the problem lies using mtr (I'd normally suggest traceroute here, but it doesn't look like it's a part of the standard Ubuntu install).

Anything beyond this is nothing you can control, but considering it works in Windows it's unlikely that this is the case. There is another possibility why you can't reach the second hop and that is that the default route isn't correct, but this address should have been given to you via DHCP like your IP address. If this is all working, we can check DNS. Try looking up a host by name using the host command: mojo-jojo david% host www.ubuntu.com www.ubuntu.com has address 82.211.81.166 If this works, then your networking should be working fine.

Re: [ubuntu-uk] ADSL problem
Can you ping the router? Can you ping the ISP's router or DNS server? If so, can you ping a host name (eg www.google.co.uk)? Or can you ping stuff, but only stuff that's on the local net? What's the output of the "ip route" command?
