I've literally tried everything to try and get the internet to work i downloaded the realtek drivers from realteks official website and i put them on a flash drive then compiled them in terminal and installed and everything appears to be successful i blacklisted the realtek 8169 which was the default kernel installed for me. i ran modprobe -r realtek it shows r8168 is running. then at the top of the screen it shows i have a wired connection and its working with the up and down arrows (which wasnt there before) in network manager but when i go to use the firefox browser it says use offline. and the network disconnects it appears like its disconnecting on and off flashing like its trying to connect but cant make a full connection. i tried changing the connection to DHCP,turned off ipv6 their must be something im unaware of that im not doing. this has been extremely frustrating any additional information ill be glad to provide thank you.

heres some logs out of terminal

im also willing to do a fresh install if someone can help me fix this problem...

an update: freshly installed Ubuntu 13.04 64 bit Edition still no internt: trying to install build essentials downloaded it from the internet onto a usb and i get Dependency is not satisfiable: g++ (>=4:4.4.3) when i click on the file build-essential_11.6ubuntu4_amd64.deb on the usb drive.

i also have both realtek drivers on the usb device both r8168_8.035.00.orig.tar.bz2 which i got from here & r8168_8.036.00.tar.bz2 which i got from Realtek

copied both to the home directory extracted opened terminal running command

cd /r8168-8.036.00 then ./autorun.sh

I will post logs soon:

Welcome to Ask Ubuntu! Could you rewrite your question to be more succinct about what the issue is exactly and what you've tried? Right now it's more with quite some personal frustration - which does not help in getting an answer, I'm afraid. Also please take care about proper formatting - it helps a lot to read your question and improves the chance of finding answers. –  gertvdijk Jul 17 '13 at 21:15
    
The issue is iv istalled ubuntu 13.04 and their is no internet connection ill reword it but i tried to provide as much information as possible this is my first time actually using a online forum for help so apologies if it wasnt clear and yes iv been extremely frustrated with this. –  Just Smith Jul 17 '13 at 23:10
    
Try open up terminal and type sudo dhclient eth0 –  linuxk Jul 17 '13 at 23:56
    
that gives me a flashing cursor and the command does not go through it just hangs. –  Just Smith Jul 18 '13 at 0:10
    
Going to install ubuntu and do this step by step and give u guys every step as i do it downloading RealTekDrivers Downloading Build essentials and putting that all on a flash drive going to install build essentials then try compiling the realtek drivers, then ill try running the command sudo dhclient eth0 will let you know results –  Just Smith Jul 18 '13 at 0:14

I had the same problem with my realtek driver, did all the same stuff (using r8168)expect I starting with trying to run DHCP. When i switched to static it went away (but making it static took some trickery because for whatever reason if i clicked add it wouldn't let me save the config). I would suggest running in static and make sure you dont have an address saved in your router for that MAC address. I am by all definitions a noob but it worked for me.

Good Luck,

Welcome to Ask Ubuntu Josh! Thanks for posting this answer, although, it would be great if you actually include steps on how to "switch it to static". Because your answer just says "switch to static", but not everyone knows how to do that =), and especially because you said "it took some trickery". We like to post informative and definitive answers here at Ask Ubuntu. You can always edit your answer to include more information by clicking on the edit link right underneath the text of your answer. Thanks! –  Alaa Sep 21 '13 at 7:30
    
Thanks for this answer it is helpful +1. Maybe the static routing table on my router is causing my issue. I will try to remove that. –  bjackfly Oct 22 '13 at 18:00

I had a similar problem. The solution I found was resetting the BIOS.

I installed Ubuntu. Then worked on it for a few days. Then installed Apache2 and Tomcat. Suddenly the wired internet stopped working. looking at the dmesg log, I could see that connecting to eth0 failed on the r8169 port.

Eventually I tried to reinstall Ubuntu (12.04). The installation program failed to find internet (something which was successful a few days earlier). Suspecting HW problem I updated BIOS to latest version (ASUS M4A785-M). It didnt help. Struggling a few more hours, then tried to reset the BIOS (removing the battery and shortcutting the reset pin on the motherboard). This did the trick. Now the wired NW works again.

BTW. When the Wired NW failed, wifi still worked flawless (via wifi dongle).
