I'm new to Ubuntu - to be honest this is my very first day trying it... and I've already spent hours trying to make my wired connection work.
I've been using this wired network with Windows and OSX, and in both systems I also had some trouble trying to connect in the past (and the troubleshooters did their magic and helped me get connected).
Today, this is what I got:
I'm running Ubuntu 11.10;
ifconfig:
eth0 Link encap:Ethernet HWaddr 78:2b:cb:c3:bf:8f

I also have some information from Windows ipconfig /all that I ran at my friend's machine
Ipv6 Address: <address> preferential
Ipv4 Address: 172.26.65.23 <preferential>
Netmask: 255.255.254.0
Default Gateway: 172.26.64.1
DHCP Server : <address>
DNS Servers : <address>
DNS Suffix : <suffix>
The weird thing is that I've tried to configure everything manually, using "Network Connections". When I add everything inside IPv4 Settings, the connection is finally successful, but only for 4~5 seconds before getting disconnected again...
Update:I just changed the Connection Method to "Local-Link Only", and the same described above happens: At first, it says "Connection Stablished", but after a few seconds, the wired network gets disconnected.
I hope someone can help me get connected!
Thanks!
