I have installed 13.04 (64bit) and after not having any wired internet, did a fresh install with 12.04 (64bit). The machine was previously running Windows 7 with wired connection working fine. A wierd issue is that normal Google searches (even images!) work from Firefox. Clicking on any links fails, however.
I cannot paste terminal outputs as I only have wired access from the Ubuntu machine.
uname -r
shows that the kernel is: 3.8.0-29-generic
.
ifconfig
shows that eth0
has an inet address (129.11.224.156)
Pinging google.com
or 173.194.70.101
gives the following result:
PING www.google.com (173.194.70.101) 56(84) bytes of data
4 packets transmitted, 0 received, 100% packet loss, time 3023ms
Pinging the router is successful:
4 packets transmitted, 4 received, 0% packet loss, time 3000ms
dmesg
gives the following output for eth0:
tg3 0000:02:00.0 eth0: Link is up at 100 Mbps, full duplex
tg3 0000:02:00.0 eth0: Flow control is off for TX and off for RX
Let me know if I need to provide more information.
Thanks!

Update 2:
Changing the mtu
to 1472 and restarting the network did not have any effect
Here is the output for cat /etc/network/interfaces
:
auto lo
iface lo inet loopback
Update 3:
Ok so apparently I need to go through a proxy server. I have followed instructions given here:
How to Configure Ubuntu desktop to use your proxy server
This has been successful in enabling fullinternet access. I have set proxies following a few instructions here.
Thank you for the help!
sudo lshw -class network
androute -n
sudo ifconfig eth0 mtu 1472
and then restart the networksudo /etc/init.d/networking restart
. If this doesn't help, provide us this file:cat /etc/network/interfaces
