Yesterday I installed Ubuntu 13.04 on a dualboot with Windows 7 preinstalled. Both my wireless and wired connections work fine on Windows 7. Wireless is working fine on Ubuntu also- but cannot get any connection through wired ethernet in ubuntu. The network adapter on my laptop is a Realtek PCIE. Here's the output of ifconfig:

`eth0      Link encap:Ethernet  HWaddr dc:0e:a1:3c:86:e5   
      inet6 addr: fe80::de0e:a1ff:fe3c:86e5/64 Scope:Link 
      UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1 
      RX packets:7177 errors:0 dropped:36 overruns:0 frame:0 
      TX packets:259 errors:0 dropped:0 overruns:0 carrier:0 
      collisions:0 txqueuelen:1000 
      RX bytes:491744 (491.7 KB)  TX bytes:61576 (61.5 KB) `

Any help on how I could get my wired network working? I really need ethernet working cos I only have wireless connection at my Uni... but wired broadband at home!

Can you please open the terminal and run the below command to show what Ethernet controller you have? lspci | egrep -i --color 'network|ethernet' –  Arnold Sep 12 '13 at 16:18

Thanks for your reply @Arnold . I now see something different Before- when I was trying to connect- Ubuntu just kept on trying and failing to connect eventually. But right now- when I rebooted back to Ubuntu-I see the wired connection is connected- but I cant access any pages from mozilla! Any ideas? Here's the output for ethernet controller by the way 01:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8101E/RTL8102E PCI Express Fast Ethernet controller (rev 05) 02:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8188CE 802.11b/g/n WiFi Adapter (rev 01) –  T K Sep 12 '13 at 19:36
    
You're welcome. Can you show the output of this command? sudo cat /etc/resolv.conf –  Arnold Sep 18 '13 at 15:42
    
The output of your ifconfig shows that you're getting an ipv6 ip address which should be fine unless route for ipv6 is not permitted on your router. I'm sure, in your Windows 7 dual-boot your getting ipv4. –  Arnold Sep 18 '13 at 15:47
